Meta-Analysis Review
BACKGROUND
Chronic suppurative otitis media (CSOM) is a chronic inflammation and infection of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane. The predominant symptoms of CSOM are ear discharge and hearing loss. Systemic antibiotics are a commonly used treatment option for CSOM, which act to kill or inhibit the growth of micro-organisms that may be responsible for the infection. Antibiotics can be used alone or in addition to other treatments for CSOM.
OBJECTIVES
To assess the effects of systemic antibiotics for people with CSOM.
SEARCH METHODS
The Cochrane ENT Information Specialist searched the Cochrane ENT Register; Central Register of Controlled Trials (CENTRAL via the Cochrane Register of Studies); Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 16 March 2020.
SELECTION CRITERIA
We included randomised controlled trials comparing systemic antibiotics (oral, injection) against placebo/no treatment or other systemic antibiotics with at least a one-week follow-up period, involving patients with chronic (at least two weeks) ear discharge of unknown cause or due to CSOM. Other treatments were allowed if both treatment and control arms also received it.
DATA COLLECTION AND ANALYSIS
We used the standard Cochrane methodological procedures. We used GRADE to assess the certainty of the evidence for each outcome. Our primary outcomes were: resolution of ear discharge or 'dry ear' (whether otoscopically confirmed or not, measured at between one week and up to two weeks, two weeks to up to four weeks, and after four weeks); health-related quality of life using a validated instrument; ear pain (otalgia) or discomfort or local irritation. Secondary outcomes included hearing, serious complications and ototoxicity measured in several ways.
MAIN RESULTS
We included 18 studies (2135 participants) with unclear or high risk of bias. 1. Systemic antibiotics versus no treatment/placebo It is very uncertain if there is a difference between systemic (intravenous) antibiotics and placebo in the resolution of ear discharge at between one and two weeks (risk ratio (RR) 8.47, 95% confidence interval (CI) 1.88 to 38.21; 33 participants; 1 study; very low-certainty evidence). The study did not report results for resolution of ear discharge after two weeks. Health-related quality of life was not reported. The evidence is very uncertain for hearing and serious (intracranial) complications. Ear pain and suspected ototoxicity were not reported. 2. Systemic antibiotics versus no treatment/placebo (both study arms received topical antibiotics) Six studies were included of which five presented useable data. There may be little or no difference in the resolution of ear discharge at between one to two weeks for oral ciprofloxacin compared to placebo or no treatment when ciprofloxacin ear drops were used in both intervention arms (RR 1.02, 95% CI 0.93 to 1.12; 390 participants; low-certainty evidence). No results after two weeks were reported. Health-related quality of life was not reported. The evidence is very uncertain for ear pain, serious complications and suspected ototoxicity. 3. Systemic antibiotics versus no treatment/placebo (both study arms received other background treatments) Two studies used topical antibiotics plus steroids as background treatment in both arms. It is very uncertain if there is a difference in resolution of ear discharge between metronidazole and placebo at four weeks (RR 0.91, 95% CI 0.51 to 1.65; 40 participants; 1 study; very low-certainty evidence). This study did not report other outcomes. It is also very uncertain if resolution of ear discharge at six weeks was improved with co-trimoxazole compared to placebo (RR 1.54, 95% CI 1.09 to 2.16; 98 participants; 1 study; very low-certainty evidence). Resolution of ear discharge was not reported at other time points. From the narrative report there was no evidence of a difference between groups for health-related quality of life, hearing or serious complications (very low-certainty evidence). One study (136 participants) used topical antiseptics as background treatment in both arms and found similar resolution of ear discharge between the amoxicillin and no treatment groups at three to four months (RR 1.03, 95% CI 0.75 to 1.41; 136 participants; 1 study; very low-certainty evidence). The narrative report indicated no evidence of differences in hearing or suspected ototoxicity (both very low-certainty evidence). No other outcomes were reported. 4. Different types of systemic antibiotics This is a summary of four comparisons, where different antibiotics were compared to each other. Eight studies compared different types of systemic antibiotics against each other: quinolones against beta-lactams (four studies), lincosamides against nitroimidazoles (one study) and comparisons of different types of beta-lactams (three studies). It was not possible to conclude if there was one class or type of systemic antibiotic that was better in terms of resolution of ear discharge. The studies did not report adverse events well.
AUTHORS' CONCLUSIONS
There was a limited amount of evidence available to examine whether systemic antibiotics are effective in achieving resolution of ear discharge for people with CSOM. When used alone (with or without aural toileting), we are very uncertain if systemic antibiotics are more effective than placebo or no treatment. When added to an effective intervention such as topical antibiotics, there seems to be little or no difference in resolution of ear discharge (low-certainty evidence). Data were only available for certain classes of antibiotics and it is very uncertain whether one class of systemic antibiotic may be more effective than another. Adverse effects of systemic antibiotics were poorly reported in the studies included. As we found very sparse evidence for their efficacy, the possibility of adverse events may detract from their use for CSOM.

Meta-Analysis Review
OBJECTIVE(S)
Tympanostomy tube (TT) placement is the most common surgical procedure in children. Less than 10% of TT do not self-extrude. This study is a systematic review (SR) on elective TT removal in the pediatric population: timing, perforation rates, and role of simultaneous repair. A PICOTS (population, intervention, comparison, outcome, timing, setting) question was formulated: In pediatric patients who have retained TT, what is the preferred time to elective removal of such tubes, and what are the outcomes in terms of perforation rates? Does an intervention at the time of TT removal improve perforation rates?
STUDY DESIGN
Systematic review and meta-analysis.
METHODS
We searched four major electronic databases: EMBASE, MEDLINE, CDSR, CCRCT for articles published prior to 02/19/20. EndNote® was used to gather references, review abstracts, and obtain full text articles. Inclusion criteria were studies reporting patients aged 0 to 18 years undergoing elective TT removal with follow-up greater than 3 months. Exclusion criteria included patients >18 years, duplicate patient series, or case series with fewer than five patients. Articles that were not available in English, not available in full text, and those that only addressed long-acting TT were excluded. Data were pooled and meta-analysis was conducted to examine how timing of TT removal, patching of the tympanic membrane, or any TM intervention at TT removal affected outcomes.
RESULTS
A total of 1,064 references were found. We identified 63 unique studies for full text review. Of these, 17 were selected for SR. MINORS (Methodological Index for Nonrandomized Studies) scores were low-revealing high bias among the studies. Reported perforation rates after elective TT removal ranged from 0% to 57%. Four studies had data suitable for comparative meta-analysis, which showed a significant increase in perforation rates after elective removal of TT after 3 years compared to removal prior to 3 years (OR 2.89; CI 1.78-4.69). No difference in perforation rates were identified when TM intervention vs. no intervention at time of TT removal was performed (six studies: OR 1.21; CI 0.71-2.07). No difference in perforation rates was identified when the type of TM intervention was compared, including freshening of TM edges, to patching with various materials (paper, fat, gelfoam®/gelfilm®, Trichloroacetic acid) (three studies: OR 1.07; CI 0.52-2.19).
CONCLUSION
From the data reviewed in this SR and meta-analysis, elective TT removal at or prior to 3 years' retention showed decreased perforation rates. However, TM intervention at the time of TT removal was not shown to lower perforation rates. In the absence of tube complications such as granuloma formation, nonfunctional tube, or chronic tube otorrhea, it may be reasonable to wait up to 3 years to electively remove a retained TT.

Review
Consumers' and health providers' views and perceptions of partnering to improve health services design, delivery and evaluation: a co-produced qualitative evidence synthesis.
BACKGROUND
Partnering with consumers in the planning, delivery and evaluation of health services is an essential component of person-centred care. There are many ways to partner with consumers to improve health services, including formal group partnerships (such as committees, boards or steering groups). However, consumers' and health providers' views and experiences of formal group partnerships remain unclear. In this qualitative evidence synthesis (QES), we focus specifically on formal group partnerships where health providers and consumers share decision-making about planning, delivering and/or evaluating health services. Formal group partnerships were selected because they are widely used throughout the world to improve person-centred care. For the purposes of this QES, the term 'consumer' refers to a person who is a patient, carer or community member who brings their perspective to health service partnerships. 'Health provider' refers to a person with a health policy, management, administrative or clinical role who participates in formal partnerships in an advisory or representative capacity. This QES was co-produced with a Stakeholder Panel of consumers and health providers. The QES was undertaken concurrently with a Cochrane intervention review entitled Effects of consumers and health providers working in partnership on health services planning, delivery and evaluation.
OBJECTIVES
1. To synthesise the views and experiences of consumers and health providers of formal partnership approaches that aimed to improve planning, delivery or evaluation of health services. 2. To identify best practice principles for formal partnership approaches in health services by understanding consumers' and health providers' views and experiences.
SEARCH METHODS
We searched MEDLINE, Embase, PsycINFO and CINAHL for studies published between January 2000 and October 2018. We also searched grey literature sources including websites of relevant research and policy organisations involved in promoting person-centred care.
SELECTION CRITERIA
We included qualitative studies that explored consumers' and health providers' perceptions and experiences of partnering in formal group formats to improve the planning, delivery or evaluation of health services.
DATA COLLECTION AND ANALYSIS
Following completion of abstract and full-text screening, we used purposive sampling to select a sample of eligible studies that covered a range of pre-defined criteria, including rich data, range of countries and country income level, settings, participants, and types of partnership activities. A Framework Synthesis approach was used to synthesise the findings of the sample. We appraised the quality of each study using the CASP (Critical Appraisal Skill Program) tool. We assessed our confidence in the findings using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach. The Stakeholder Panel was involved in each stage of the review from development of the protocol to development of the best practice principles.
MAIN RESULTS
We found 182 studies that were eligible for inclusion. From this group, we selected 33 studies to include in the final synthesis. These studies came from a wide range of countries including 28 from high-income countries and five from low- or middle-income countries (LMICs). Each of the studies included the experiences and views of consumers and/or health providers of partnering in formal group formats. The results were divided into the following categories. Contextual factors influencing partnerships: government policy, policy implementation processes and funding, as well as the organisational context of the health service, could facilitate or impede partnering (moderate level of confidence). Consumer recruitment: consumer recruitment occurred in different ways and consumers managed the recruitment process in a minority of studies only (high level of confidence). Recruiting a range of consumers who were reflective of the clinic's demographic population was considered desirable, particularly by health providers (high level of confidence). Some health providers perceived that individual consumers' experiences were not generalisable to the broader population whereas consumers perceived it could be problematic to aim to represent a broad range of community views (high level of confidence). Partnership dynamics and processes: positive interpersonal dynamics between health providers and consumers facilitated partnerships (high level of confidence). However, formal meeting formats and lack of clarity about the consumer role could constrain consumers' involvement (high level of confidence). Health providers' professional status, technical knowledge and use of jargon were intimidating for some consumers (high level of confidence) and consumers could feel their experiential knowledge was not valued (moderate level of confidence). Consumers could also become frustrated when health providers dominated the meeting agenda (moderate level of confidence) and when they experienced token involvement, such as a lack of decision-making power (high level of confidence) Perceived impacts on partnership participants: partnering could affect health provider and consumer participants in both positive and negative ways (high level of confidence). Perceived impacts on health service planning, delivery and evaluation: partnering was perceived to improve the person-centredness of health service culture (high level of confidence), improve the built environment of the health service (high level of confidence), improve health service design and delivery e.g. facilitate 'out of hours' services or treatment closer to home (high level of confidence), enhance community ownership of health services, particularly in LMICs (moderate level of confidence), and improve consumer involvement in strategic decision-making, under certain conditions (moderate level of confidence). There was limited evidence suggesting partnering may improve health service evaluation (very low level of confidence). Best practice principles for formal partnering to promote person-centred care were developed from these findings. The principles were developed collaboratively with the Stakeholder Panel and included leadership and health service culture; diversity; equity; mutual respect; shared vision and regular communication; shared agendas and decision-making; influence and sustainability.
AUTHORS' CONCLUSIONS
Successful formal group partnerships with consumers require health providers to continually reflect and address power imbalances that may constrain consumers' participation. Such imbalances may be particularly acute in recruitment procedures, meeting structure and content and decision-making processes. Formal group partnerships were perceived to improve the physical environment of health services, the person-centredness of health service culture and health service design and delivery. Implementing the best practice principles may help to address power imbalances, strengthen formal partnering, improve the experiences of consumers and health providers and positively affect partnership outcomes.

UNLABELLED
Previous surveys indicate that the majority of clinicians recommend avoidance of air travel for a period of time following an acute orbital fracture. This advice has largely been based on the theoretical risk that in-flight pressure variation may exacerbate orbital emphysema and produce visual compromise, though no previous reviews have been conducted on the evidence underpinning this advice. The purpose of this study was, therefore, to conduct a systematic review of the literature pertaining to the safety of air travel in the setting of an acute orbital fracture. A systematic review of the OVID Medline database - and of cases referenced as providing evidence for adverse outcomes due to flying with an orbital fracture - was carried out.Two articles were identified from the literature with data specific to patients who undertook air travel following orbital fractures. A large case series identified no complications in patients exposed to both pressurized and unpressurized air travel, and only a single case report detailed an adverse outcome requiring intervention. The remainder of the articles that had previously been cited as evidence against air travel involved additional factors such as intra-ocular pathologies. There is, therefore, a paucity of evidence to support the conventional advice regarding avoidance of air travel, though clinicians should exclude the possibility of an associated intra-ocular injury, advise against nose-blowing in flight, and provide advice regarding alternative methods to the Valsalva maneuver for equalizing middle ear pressure in flight.

Acta Oto-laryngologica Jun 2021Eosinophilic Otitis Media (EOM) is a relatively newly defined entity of recurrent and resistant otitis media.
BACKGROUND
Eosinophilic Otitis Media (EOM) is a relatively newly defined entity of recurrent and resistant otitis media.
OBJECTIVE
To perform a systematic review of otologic manifestations, diagnosis and management of eosinophilic otitis media (EOM).
METHODS
393 patients diagnosed with EOM of 26 studies met inclusion criteria and were assessed for demographics, otologic manifestations, diagnostic criteria fulfilled, and medical and surgical treatments.
RESULTS
Most common otologic manifestations were hearing loss (65%), otitis media with effusion (16%), tympanic membrane perforation (13%), and otorrhea (13%). 93% had a predominantly eosinophilic middle ear effusion, 95% had asthma, 85% had a highly viscous middle ear effusion, 71% had nasal polyposis, and 58% had resistance to conventional treatment. For treatment, 39% received intratympanic steroid injections, 33% received systemic steroids, 17% received steroid ear drops and 13% received a biological agent. 39% of patients underwent a surgical intervention with 26% receiving functional endoscopic sinus surgery and 18% receiving myringotomy with tube insertion. Success rates were highest with use of intratympanic steroids (45%), systemic steroids (26%), and biological agents (58%).
CONCLUSION
Intratympanic steroids show the most efficacy in treating EOM, and aggressive optimization of asthma may be beneficial in resolving otologic symptoms. Surgery should be reserved for refractory cases and complications.

Review
Endoscopes are increasingly being used in middle ear surgery as an adjunct to or replacement for the operative microscope. The superior visualization of hidden areas and a minimally invasive transcanal approach to the pathology are some of the endoscope's advantages. The aim of this review is to compare the surgical outcomes of a totally endoscopic transcanal approach with a conventional microscopic approach for type 1 tympanoplasty in patients with chronic otitis media (COM) in order to establish if endoscopic myringoplasty (EM) could be a better alternative to microscopic myringoplasty (MM). A literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. The selected articles were identified by searching PubMed Central, PubMed, MEDLINE and Embase databases for the relevant publications. Only studies where the same surgeon in the department performed both endoscopic and microscopic myringoplasty have been included in the review. The results suggest that with an endoscopic approach, minimally invasive myringoplasty can be achieved with a similar graft success rate and postoperative air-bone gap (ABG) improvement, a shorter operative time and less postoperative complications compared to a microscopic approach.

Review
OBJECTIVE
The objectives of this review are to identify the types of materials with their associated complications and respective considerations when used to obliterate the mastoid cavity.
METHODS
A systematic search was performed across PubMed, Embase, Medline and Cochrane databases from January 2009 to January 2020 for randomized controlled trials and observational studies of patients that underwent mastoid obliteration. Studies that fulfilled the inclusion criteria were screened and scored according to the MINORS and relevance scores to determine final inclusion. Types of complications were grouped into minor and major complications based on the Clavien-Dindo classification.
RESULTS
Two thousand five hundred and seventy-eight ears were evaluated. There were a total of 165 (7.9%) minor and 142 (6.8%) major complications in the autologous group. Overall complication rate is 14.8%. The major complications were largely recurrent and residual disease requiring revision surgery. There were 10 (18.5%) minor complications and three (5.6%) major complications in the allogenic group. The cumulative complications risk is 24%. For the synthetic group, there were 39 (8.0%) minor and 34 (7.6%) major complications. The cumulative complication rate is 16.6%.
CONCLUSION
Current evidence on materials for mastoid obliteration has been evolving. Each material has its strengths and limitations. The trend over the last decade favours the use of autologous materials. The principle of using a material remains being cautious of not reimplanting skin that can lead to the development of a cholesteatoma. The choice of materials is dependent on patient factors as well as the surgeons' preference and experience.

Otology & Neurotology : Official... Aug 2021To investigate the relationship between laryngopharyngeal reflux (LPR) and recurrent (ROM) or chronic otitis media with effusion (COME).
OBJECTIVES
To investigate the relationship between laryngopharyngeal reflux (LPR) and recurrent (ROM) or chronic otitis media with effusion (COME).
DATABASES
PubMed, Scopus, and Cochrane Library.
METHODS
Three authors searched articles published between January 1980 and September 2020 about the association between LPR and the development of recurrent or chronic otitis media. Inclusion, exclusion, diagnostic criteria, and clinical outcome evaluation of included studies were analyzed using PRISMA criteria. The bias analysis of included studies was evaluated with the Tool to assess Risk of Bias of the CLARITY group.
RESULTS
Twenty-six clinical and three experimental articles met our inclusion criteria, accounting for 1,624 children and 144 adults with COME or ROM. According to the pH study type, the prevalence of LPR and gastroesophageal reflux disease (GERD) in OM patients were 28.7% (range, 8-100%) and 40.7 (range, 18-64%), respectively. The majority of studies identified pepsin or pepsinogen in middle ear effusion, with a range of mean concentrations depending on the technique used to measure pepsin. There was an important heterogeneity between studies regarding definition of COME, ROM, and LPR, exclusion criteria, methods used to measure pepsin/pepsinogen in middle ear secretions and outcome assessments.
CONCLUSION
The association between LPR and OM is still unclear. Future clinical and experimental studies are needed to investigate the association between LPR and OM in both children and adults through extensive gastric content analysis in middle ear suppurations and impedance-pH monitoring considering acid, weakly acid, and alkaline reflux events.

Meta-Analysis Review
OBJECTIVE
Juvenile Otosclerosis (JO) and Congenital Stapes Footplate Fixation (CSFF) are rare ossicular chain disorders seen in the paediatric population and present with conductive hearing loss. Ongoing controversy exists regarding the role of surgical intervention in JO and CSFF given the poorer hearing outcomes and complications when compared with surgical intervention for adult otosclerosis. The objective of this study is to assess the published data on the surgical outcomes of JO and CSFF in order to guide clinicians and counsel patients on the various medical options for these disease entities.
METHODS
A systematic review of MEDLINE, EMBASE and Cochrane was performed with inclusion criteria of children with JO or CSFF and hearing outcomes following stapes surgery. Studies identified by the search were reviewed and assessed by two independent reviewers in line with the PRISMA guidelines.
RESULTS
464 articles were initially reviewed and 28 articles met inclusion in the systematic review and meta-analysis. A total of 810 ears (473 and 337 cases of JO and CSFF respectively) underwent stapes surgery. Average age at time of surgery for JO and CSFF was 14.3 and 10.2 years old respectively. The mean pre-operative Air-Bone-Gap (ABG) for JO and CSFF was 31.8 ± 5.2 dB and 39.4 ± 10 dB respectively. Following stapes surgery, the mean post-operative ABG for JO and CSFF was 9.6 ± 6 dB and 19.2 ± 12.5 dB respectively. Surgical success rate (defined as ABG <10 dB) was 81% for JO and 41% for CSFF. Mean ABG gain for JO and CSFF was 24.8 dB (95% CI: 18.6-33.1) and 22.6 dB (95% CI: 18.4-27.8) respectively. The reported number of dead ears was 4/473 (0.8%) for JO and 2/337 (0.6%) for CSFF. 23 cases (2.8%) reported sensorineural hearing loss (SNHL) >10 dB.
CONCLUSION
CSFF was associated with poorer hearing outcomes compared to JO, however both entities showed similar improvement in ABG post operatively. Counselling patients and their families on the surgical success rates and complications of JO or CSFF is an important part of the decision making process when deciding between a surgical option or conservative measures such as hearing aids.

The Laryngoscope Dec 2022To examine the effectiveness of Eustachian tube procedures for the treatment of baro-challenge Eustachian tube dysfunction. (Review)
Review
OBJECTIVE
To examine the effectiveness of Eustachian tube procedures for the treatment of baro-challenge Eustachian tube dysfunction.
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, databases, including PubMed (National Library of Medicine, National Institutes of Health), Scopus (Elsevier), and CINAHL (EBSCO), were searched for articles examining the effectiveness of Eustachian tube procedures for baro-challenge Eustachian tube dysfunction. Outcome measures included symptom resolution, ability to return to work, equalization problems (EP) scores, Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores, and pressure chamber testing parameters. Pooled meta-analysis was performed for dichotomous measures and ETDQ-7 scores.
RESULTS
Eleven articles with 81 patients were included. Seventy-two patients from 10 articles underwent balloon Eustachian tube dilation; nine patients in 1 study underwent laser Eustachian tuboplasty (LET). All 81 patients were preoperatively symptomatic with barometric pressure change, and 26/30 (86.7%) were unable to work due to symptoms. On meta-analysis, after balloon dilation Eustachian tuboplasty (BDET), 82.5% (n = 30 [95% confidence interval: 42%-100%]) had improvement in ability to valsalva, 79.1% (n = 16 [57.9%-94.1%]) in ability to return to work, and 84.3% (n = 69 [69.8%-94.7%]) in any symptom. Of 25 patients with individual ETDQ-7 scores, 79.1% [51.4, 96.9] had improvements after BDET. For four case series with 36 patients, ETDQ-7 scores decreased by 1.2 [0.7, 1.7] (p < 0.00001). Of 20 patients with preoperative ETDQ-7 scores >2.0, there was a mean decrease of 2.1 [1.3, 2.8] (p < 0.00001).
CONCLUSION
From the available evidence, Eustachian tube procedures appear to be effective at improving symptoms of baro-challenge Eustachian tube dysfunction. However, higher quality evidence is needed to support making definite recommendations for the use of balloon Eustachian tube dilation or LET for these patients. Laryngoscope, 132:2473-2483, 2022.
