Review
BACKGROUND
Group A streptococcal(GAS) meningitis is a severe disease with a high case fatality rate. In the era of increasing GAS meningitis, our understanding about this disease is limited.
PURPOSE
To gain a better understanding about GAS meningitis.
METHODS
Five new cases with GAS meningitis were reported. GAS meningitis related literatures were searched for systematic review in PUBMED and EMBASE. Case reports and case series on paediatric cases were included. Information on demographics, risk factors, symptoms, treatments, outcomes, and emm types of GAS was summarized.
RESULTS
Totally 263 cases were included. Among 100 individuals, 9.9% (8/81) had prior varicella, 11.1% (9/81) had anatomical factors, and 53.2% (42/79) had extracranial infections. Soft tissue infections were common among infants (10/29, 34.5%), while ear/sinus infections were more prevalent in children ≥ 3 years (21/42, 50.0%). The overall case fatality rate (CFR) was 16.2% (12/74). High risk of death was found in patients with shock or systemic complications, young children(< 3 years) and cases related to hematogenic spread. The predominate cause of death was shock(6/8). Among the 163 patients included in case series studies, ear/sinus infections ranged from 21.4 to 62.5%, while STSS/shock ranged from 12.5 to 35.7%, and the CFR ranged from 5.9 to 42.9%.
CONCLUSIONS
A history of varicella, soft tissue infections, parameningeal infections and CSF leaks are important clinical clues to GAS in children with meningitis. Young children and hematogenic spread related cases need to be closely monitored for shock due to the high risk of death.

Review
BACKGROUND
Facial nerve hemangiomas (FNHs) are rare tumors that primarily occur near the geniculate ganglion in the temporal bone. Despite their rarity, they can cause significant facial nerve dysfunction. The optimal management approach for FNHs remains uncertain, with surgery being the mainstay but subject to debate regarding the extent of resection and preservation of the facial nerve.
METHODS
Systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We queried the PubMed/Medline (accessed on 5 March 2024) electronic database using combinations of the following search terms and words text: "geniculate ganglion hemangioma", "ganglional hemangioma", "hemangioma of the facial nerve", "facial hemangioma", and "intratemporal hemangioma".
RESULTS
We identified a total of 30 literatures (321 patients). The most common site involved for the facial nerve hemangioma was the geniculate ganglion area followed by internal auditory canal, tympanic segment, labyrinthine segment and mastoid involvement. All patients were treated with conservative management or surgery. We report a 48-year-old female patient with HB grade 2 facial palsy and hemifacial spasm underwent SRS using Cyberknife technology. The treatment targeted the FNH in the left internal acoustic canal near the geniculate ganglion. Six months post-treatment, clinical improvement was evident, and lesion control was confirmed in a follow-up brain MRI.
CONCLUSION
The rarity of FNHs contributes to the lack of consensus on optimal management. This illustrative case demonstrates the feasibility of SRS as a standalone treatment for FNHs.

Review
PURPOSE
This review aims to investigate the effects of the Gufoni maneuver on horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV).
METHODS
A comprehensive search, including PubMed, PEDro, REHABDATA, SCOPUS, EMBASE, and Web of Science, was conducted to determine randomized clinical trials (RCTs) studying the effects of the Gufoni maneuver for HC-BPPV from inception to March 1, 2024. The quality of the included studies was estimated using the Physiotherapy Evidence Database (PEDro) scale.
RESULTS
Ten randomized controlled trials (RCTs) were included in this review with a total of 1025 HC-BPPV patients (mean age = 58.58 years; 63% female; 55% right-side HC-HBPPV; 49% geotropic HC-BPPV). The included RCTs ranged from 4 to 9 out of 10 (median = 6.5) on the PEDro scale. The included studies showed that the Gufoni maneuver revealed efficacy when compared to the sham maneuver but not when compared to other maneuvers such as the Barbecue roll maneuver, the Appiani maneuver, the Mastoid oscillation, the head shaking, and the modified Gufoni maneuver.
CONCLUSIONS
The Gufoni maneuver is considered an option for treating patients with geotropic or apogeotropic HC-BPPV. Precise diagnosis of the BPPV, the subtype of HC-BPPV, symptom duration, history of previous BPPV attacks, the applied methods of maneuver and the proficiency of the clinician performing the maneuver, proper diagnosis, presence of any underlying health conditions are critical for successful treatment. Further studies are strongly warranted.

The Journal of Laryngology and Otology Mar 2024This study aimed to form astute deductions regarding the presentation, treatment and mortality of otogenic brain complications.
OBJECTIVE
This study aimed to form astute deductions regarding the presentation, treatment and mortality of otogenic brain complications.
METHODS
A systematic literature search of four medical databases (PubMed, Embase, Web of Science and Scopus) was conducted. Studies associated with otogenic brain complications were considered eligible. Fixed- and random-effects model meta-analysis was developed to assess the proportion estimate for each outcome individually.
RESULTS
Twenty-eight studies, with 1650 patients in total, were included. In 66 per cent of patients there was a known history of chronic otitis media. The most common symptoms were purulent otorrhoea (84 per cent), headache (65 per cent) and otalgia (45 per cent). A brain abscess was observed in 49 per cent of patients, followed by meningitis (34 per cent) and sinus thrombosis (22 per cent). A combination of surgical and conservative therapy was chosen in 84.3 per cent of cases and the mortality rate approached 11.1 per cent.
CONCLUSION
Otogenic brain complications are a possibly life-threatening condition. Prompt imaging examination may set the final diagnosis and lead to an effective treatment.

Meta-Analysis
OBJECTIVE
To determine if cochlear implant (CI) is safe and effective in patients with radiation therapy (XRT)-induced sensorineural hearing loss and to discuss considerations in this population through a retrospective cohort review, systematic review, and meta-analysis.
DATABASES REVIEWED
PubMed, Cochrane Library, and Embase.
METHODS
We retrospectively reviewed all CI cases after head and neck (HN) XRT at our institution, noting intraoperative findings, postoperative complications, and hearing outcomes. Change in speech discrimination scores (SDSs) was the primary outcome measure. Systematic review was performed to identify all cases of CI after HNXRT. A meta-analysis was performed to assess SDS change.
RESULTS
The retrospective cohort review identified 12 patients who underwent CI after HNXRT. One patient with HN cancer (HNC) and one with central nervous system pathology (CNSP) received bilateral implants. Six had HNC, three had CNSP, and one had Langerhans cell histiocytosis. Eleven had abnormal findings during CI. There were no postoperative complications. Twenty articles with an additional 97 patients were suitable for systematic review inclusion. Of the 109 patients, 67 (61.5%) had HNC and 18 (16.5%) had CNSP. Abnormal intraoperative findings were common (30.3%), most frequently in the mastoid (66.7%). Postoperative complications, including wound dehiscence and infection with some requiring explantation, occurred in 10.1% of patients. Sixty-six patients were included in the meta-analysis. All demonstrated SDS improvement (mean increase, 56.2%).
CONCLUSION
Patients with prior HNXRT benefit from CI. Paying careful attention to surgical planning and technique, postoperative care, and patient expectations is imperative, as complications are not uncommon.

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.

Meta-Analysis Review
This study aimed to investigate the anatomy of the spinal accessory nerve (SAN) in the posterior cervical triangle, especially in relation to adjacent anatomical landmarks, along with a systematic review of the current literature with a meta-analysis of the data. Overall, 22 cadaveric and three prospective intraoperative studies, with a total of 1346 heminecks, were included in the analysis. The major landmarks relevant to the entry of the SAN at the posterior border of the SCM muscle (PBSCM) were found to be the mastoid apex, the great auricular point (GAP), the nerve point (NP), and the point where the PBSCM meets the upper border of the clavicle. The SAN was reported to enter the posterior cervical triangle above GAP in 100% of cases and above NP in most cases (97.5%). The mean length of the SAN along its course from the entry point to its exit point from the posterior triangle of the neck was 4.07 ± 1.13 cm. The SAN mainly gave off 1 or 2 branches (32.5% and 31%, respectively) and received either no branches or one branch in most cases (58% and 23%, respectively) from the cervical plexus during its course in the posterior cervical triangle. The major landmarks relevant to the entry of the SAN at the anterior border of the TPZ muscle (ABTPZ) were found to be the point where the ABTPZ meets the upper border of the clavicle and the midpoint of the clavicle, along with the mastoid apex, the acromion, and the transverse distance of the SAN exit point to the PBSCM. The results of the present meta-analysis will be helpful to surgeons operating in the posterior cervical triangle, aiding the avoidance of the iatrogenic injury of the SAN.

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
The mastoid process has attracted the attention of several researchers due to its protected position at the base of the skull and the fact that it is relatively compact, in addition to being highly resistant and dimorphic, considered as a gold standard anatomical structure in the determination of the sexual dimorphism of skulls. However, intrinsic and extrinsic factors may influence this anatomical structure over time, providing contradictory and ambiguous data. Therefore, other anatomical structures need to be evaluated concurrently with the mastoid process to provide better accuracy and reliability of skull sexual dimorphism data. Thus, the objective of this systematic review was to evaluate the degree of reliability of the mastoid process to determine sexual dimorphism compared to other dimorphic structures, since there are still no systematic reviews on the subject in the literature. This review follows the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and was recorded in the Prospective International Systematic Reviews Registry (PROSPERO) (CRD 42023395167 Systematic Registry) (CRD420223). The inclusion criteria for selecting the studies were based on the PICO question: "Are skull anatomical structures reliable as alternatives to determine sexual dimorphism compared to the mastoid process?". A literature search for studies was performed in the MEDLINE Scopus, Web of Science, LILACS, and Cochrane Library databases. The Kappa agreement presented an approval level of (k = 0.93). This systematic review analyzed 13 ex-vivo studies published between 2008 and 2023. The risk of bias was considered low in 12 of the studies, and high in 1 study. Based on the findings, it can be concluded that even with the limitations of this systematic review, quantitative and qualitative analyses are essential in sexual identification of human skulls, and different anatomical structures can be used as references in addition to the mastoid process, with high reliability and precision, among them the; glabella, frontal profile, superciliary arch, bizygomatic width, maximum cranial length, and nasal height.

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.
