Review
BACKGROUND
Acute mastoiditis (AM) is a severe infection of the mastoid air cells that occurs in cases of acute, sub-acute, or chronic middle ear infections. No definitive consensus regarding the management of AM has been identified. The current guidelines include a conservative approach (parenteral antibiotics alone, antibiotics plus minor surgical procedures such as myringotomy with a ventilation tube inserted or drainage of the subperiosteal abscess through retro-auricolar incision or needle aspiration) or surgical treatment (mastoidectomy). The main aim of this review was to evaluate and summarize the current knowledge about the management of pediatric AM by analyzing the current evidence in the literature.
METHODS
We examined the following bibliographic electronic databases: Pubmed and the Cochrane Library, from the inception date until February 2023. The search was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISM). The key words used for the search across electronic databases were: `mastoiditis` and `management`; `mastoiditis` and `surgery`; `mastoiditis` and `conservative`; `mastoiditis` and `antibiotics`; `mastoiditis` and `myringotomy`; `mastoiditis` and `grommet`; `mastoiditis` and `drainage`; and `mastoiditis` and `mastoidectomy`.
RESULTS
We selected 12 articles involving 1124 episodes of mastoiditis. Some of these studies considered medical therapy alone as a valid first step, whereas others considered a minor surgical intervention as an initial approach along with antibiotic therapy. Considering the studies that evaluated medical therapy as the initial sole treatment option, the success rate of antibiotics alone was 24.6%. Overall, the success rate of minor surgical procedures, excluding mastoidectomy, was 87.7%, whereas the mastoidectomy success rate was 97%.
CONCLUSIONS
Overall, there is no shared consensus on the diagnostic or therapeutic approach to mastoiditis. Conservative therapy has gained considerable ground in recent times, quite limiting the predominant role of mastoidectomy. Further studies will be necessary to definitely develop standardized protocols shared in the scientific community.

Review
This systematic review was aimed at gathering the clinical and technical applications of CAD/CAM technology for craniofacial implant placement and processing of auricular prostheses based on clinical cases. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, an electronic data search was performed. Human clinical studies utilizing digital planning, designing, and printing systems for craniofacial implant placement and processing of auricular prostheses for prosthetic rehabilitation of auricular defects were included. Following a data search, a total of 36 clinical human studies were included, which were digitally planned and executed through various virtual software to rehabilitate auricular defects. Preoperative data were collected mainly through computed tomography scans (CT scans) (55 cases); meanwhile, the most common laser scanners were the 3dMDface System (3dMD LLC, Atlanta, Georgia, USA) (6 cases) and the 3 Shape scanner (3 Shape, Copenhagen, Denmark) (6 cases). The most common digital design software are Mimics Software (Mimics Innovation Suite, Materialize, Leuven, Belgium) (18 cases), Freeform software (Freeform, NC, USA) (13 cases), and 3 Shape software (3 Shape, Copenhagen, Denmark) (12 cases). Surgical templates were designed and utilized in 35 cases to place 88 craniofacial implants in auricular defect areas. The most common craniofacial implants were Vistafix craniofacial implants (Entific Medical Systems, Goteborg, Sweden) in 22 cases. A surgical navigation system was used to place 20 craniofacial implants in the mastoid bone. Digital applications of CAD/CAM technology include, but are not limited to, study models, mirrored replicas of intact ears, molds, retentive attachments, customized implants, substructures, and silicone prostheses. The included studies demonstrated a predictable clinical outcome, reduced the patient's visits, and completed the prosthetic rehabilitation in reasonable time and at reasonable cost. However, equipment costs and trained technical staff were highlighted as possible limitations to the use of CAD/CAM systems.

Review
BACKGROUND
The prominent ear is a type of congenital ear deformity that can be corrected by a variety of nonsurgical treatments, such as splinting and the taping method. However, there is no objective evaluation method that is universally accepted. The aim of this review is to evaluate objective measurement methods that are used in the available literature to analyze nonsurgical treatment of prominent ears.
METHODS
A systematic review was performed in the MEDLINE and Embase databases in December 2022 and updated on April 2023 according to Preferred Reporting Items for Systematics and Meta-Analyses (PRISMA) guideline. Any study using objective measurements (continuous variables such as distance and angle) to evaluate the effect of nonsurgical treatment of prominent ears was included. The Joanna Briggs Institute (JBI) critical appraisal for case series was used for quality assessment.
RESULTS
A total of 286 studies were screened for eligibility, of which five articles were eligible for inclusion. All of the included studies were case series. The helix mastoid distance (HMD) is the most commonly used parameter to measure treatment outcome. Pinna and cartilage stiffness, length, and width were also used, but without clear statistical relevance. HMD was classified into grading groups (i.e. good, moderate, and poor) to evaluate the treatment's effect.
CONCLUSION
Based on the included studies, objective measurements are rarely used, and when used, they are largely heterogeneous. Although HMD was the most frequent measurement used, all studies used different definitions for the measurement and grouped subsequent outcomes differently. Automated algorithms, based on three-dimensional imaging, could be used for object measurements in the nonsurgical treatment of prominent ears.

(Review)
Review
BACKGROUND
Cholesteatomas are growths of squamous epithelium that can form inside the middle ear and mastoid cavity and damage nearby structures causing hearing loss when located at the petrous apex. The primary goal of petrous apex cholesteatoma resection is gross total removal with tympanoplasty and canal-wall up or canal-wall down tympanomastoidectomy. At present, there is no definitive surgical approach supported by greater than level 4 evidence in the literature to date.
METHODS
A systematic review was conducted utilizing PubMed, Embase, and Scopus databases. Articles were screened and selected to be reviewed in full text. The articles that met inclusion criteria were reviewed for relevant data. Data analysis, means, and standard deviations were calculated using Microsoft Excel.
RESULTS
After screening, five articles were included in the systematic review. There were a total of eight pediatric patients with nine total cholesteatomas removed. Conductive hearing loss was the most common (77%) presenting symptom. Perforations were noted in seven ears (86%). Recurrence was noted in 50% of patients with an average recurrence rate of 3.5 years (SD = 1.73). Average length of follow-up was 32.6 months (SD = 21.7). Canal-wall up was the most utilized technique (60%) and there were zero noted surgical complications. Five of the seven (71%) patients that experienced hearing loss from perforation noted improved hearing.
CONCLUSION
Due to its rarity, diagnostic evaluation and treatment can vary. Further, multi-institutional investigation is necessary to develop population-level management protocols for pediatric patients affected by petrous apex cholesteatomas.

OBJECTIVE
IgG4-related disease (IgG4-RD) involving the temporal bone is an uncommon and underrecognized pathology often mistaken for malignancy. This systematic review is the first that aims to thoroughly analyze IgG4-RD of the temporal bone.
DATABASES REVIEWED
Ovid MEDLINE, EMBASE, Cochrane Library, and Google Scholar.
METHODS
We used the following search keywords: "lgG4-RD," "skull," "skull base," "cranial," "temporal bone," "inner ear." We additionally manually searched the bibliographies of relevant articles. The JBI Critical Appraisal Checklist for Case Reports and Case Series was used to assess the risk of bias; because of the scarcity of the reports, data were available through limited case series and reports; thus, data synthesis was not possible.
RESULTS
We identified 17 studies with 22 cases with temporal bone involvement. The most common presenting symptoms were hearing loss, otalgia, and headache. The mastoid and petrous bone were the most affected anatomical areas. Both computed tomography and magnetic resonance imaging were used. Biopsies showed the characteristic lymphoplasmacytic infiltrate in all cases, with histopathology being the diagnostic modality that set the diagnosis. Most patients were treated with corticosteroids ± surgery or a combination of corticosteroids and immunosuppressants with 95.5% symptomatic response and disease control.
CONCLUSION
IgG4-RD of the temporal bone radiologically manifests as space-occupying, lytic lesions; clinically, it presents with vague otological symptoms. Diagnosis involves a thorough workup, with histopathology being crucial in setting a definite diagnosis. IgG4-RD tends to respond well to systemic corticosteroids, whereas surgery is mostly required for diagnostic purposes.

Review
Bezold's abscess is a deep neck abscess related to otomastoiditis. Due to the insidious clinical presentation, diagnosis can be extremely challenging, leading to delays in treatment and possible life-threatening complications. The literature currently provides a fragmented picture, presenting only single or small number of cases. The present study aims at examining our experience and the literature findings (based on PRISMA criteria) of 97 patients with Bezold's abscess, summarizing their epidemiology, pathogenesis, clinical presentation, imaging findings, and treatments. Bezold's abscess is found at any age, with overt male prevalence among adults. The clinical presentation, as well as the causative pathogens, are strikingly heterogeneous. Otomastoiditis and cholesteatoma are major risk factors. A clinical history of otitis is commonly reported (43%). CT and MRI are the main diagnostic tools, proving the erosion of the mastoid tip in 53% of patients and the presence of a concomitant cholesteatoma in 40%. Intracranial vascular (24%) or infectious (9%) complications have also been reported. Diagnosis might be easily achieved when imaging (CT) is properly applied. MRI has a limited diagnostic role, but it might be crucial whenever intracranial complications or the coexistence of cholesteatoma are suspected, helping to develop proper treatment (prompt antibiotic therapy and surgery).

Meta-Analysis Review
Clinical characteristics and an evaluation of predictors for a favourable outcome of Mycobacterium abscessus otomastoiditis: a systematic review and meta-analysis of individual participant data.
BACKGROUND
Otomastoiditis caused by Mycobacterium abscessus is rare, but its incidence has increased over the past decades and its optimal treatment remains unknown. This study aims to summarise the clinical and therapeutic features and find characteristics of patients with M. abscessus otomastoiditis associated with favourable treatment outcomes.
METHODS
We searched MEDLINE, Embase and Web of Science to identify studies including patients with M. abscessus otomastoiditis. A 1-stage individual patient data (IPD) meta-analysis was conducted. A 2-level mixed-effects linear regression model was provided for antimycobacterial treatment duration.
RESULTS
Twenty-three studies reported a total of 85 patients. Children possess a unique clinical profile including a history of ear infections, tympanostomy tube placement and antibiotic treatment. Antimycobacterial treatment was administered for 26 (interquartile range [IQR]: 15-35) weeks. Macrolides were prescribed in 98.8% of the cases. Surgery was performed in 80.5% of the cases, of which, 47.1% required revision surgery. Otalgia was a significant predictor (β = 9.3; P = .049) of antimycobacterial treatment duration.
CONCLUSIONS
Mastoid surgery (regularly requiring revision) and a multidrug regimen for a minimum of 6 months, including a minimum of 3 active agents, are most often needed to attain cure. The presence of otalgia significantly extends the treatment duration of M. abscessus otomastoiditis.

Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females. PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I test statistic, and -values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies. In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm). The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

Review
Streptococcus pneumoniae remains an important bacterial pathogen, particularly for young children in low- and middle-income countries. A systematic review was conducted of peer-reviewed literature from PubMed published as of May 13, 2020, to identify articles relevant to invasive pneumococcal disease, pneumonia, otitis media (OM), nasopharyngeal carriage (NPC), antimicrobial resistance (AMR), and vaccination coverage in Egypt, with particular focus on children ≤ 18 years of age. A total of 16 relevant articles spanning three decades were included in this review. Among studies reviewed, S. pneumoniae was the causative agent of meningitis in 21-30% of cases among hospitalized children between 1983 and 2003. One study showed that serotypes 6A and 6B predominated among meningitis cases of pediatric patients aged < 5 years. This review also revealed that S. pneumoniae was the most commonly identified bacterial pathogen of acute mastoiditis, a severe complication of acute OM, among children aged 9 months to 11 years. NPC studies showed that approximately 30% of Egyptian children were carriers of S. pneumoniae. AMR, especially to penicillin, continues to be a growing concern in low- and middle-income countries, including among Egyptian children. Several predominant serotypes were identified to be associated with penicillin resistance, such as 6B, 1, 19A, 23F, and 6A. Currently available pneumococcal vaccines (PCVs) such as PCV10 and PCV13 may provide coverage against the most prevalent circulating serotypes among Egyptian children. Comprehensive disease surveillance and immunization programs are needed to ensure that this vulnerable population is sufficiently protected against pneumococcal disease.

BACKGROUND
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can affect the nervous system, triggering problems such as the Guillain-Barre Syndrome (GBS), an association that can bring complications to the patient.
OBJECTIVE
This scoping review aimed to clarify the clinical features and analyze patients with GBS associated with SARS-CoV-2 infection, looking at morbidity, mortality, and neurological outcomes.
SEARCH STRATEGY
The search was conducted through Medline, Web of Science, Embase, CINAHAL, Latin-American and Caribbean Literature in Health Sciences (LILACS), clinicaltrials.gov, SCOPUS, and the Cochrane Central Register of Controlled Trials.
SELECTION CRITERIA
Observational studies, published after 2019, describe patients with GBS associated with SARS-CoV-2 infection. There were no language restrictions while selecting the studies.
DATA COLLECTION AND ANALYSIS
Three authors, Kleyton Santos de Medeiros, Luíza Thomé de Araújo Macêdo, and Wederson Farias de Souza, independently screened the search results using titles and abstracts. Duplicate studies were excluded. The same authors then went through the entire text to determine whether the studies met the inclusion criteria. Discrepancies were resolved by other reviewers, Ana Paula Ferreira Costa, Ayane Cristine Sarmento, and Ana Katherine Gonçalves. Finally, the selection of the studies was summarized in a PRISMA flow diagram.
MAIN RESULTS
Main manifestations were fever, coughing, dyspnea, sore throat, ageusia, anosmia, and respiratory failure, in addition to paresthesia of the upper and lower limbs, tetraparesis, facial diplegia, areflexia, asthenia, mastoid pain, acute ataxia, fatigue, numbness, swallowing disorder, and moderate low back pain.
CONCLUSION
Coronavirus disease 2019 (COVID-19) can trigger the GBS, despite the few studies on this topic. Patients had clinical manifestations of COVID-19 infection and neurological manifestations characterizing GBS.
