Objective: Steroids given systemically, locally, or both are the mainstay of treatment for acute acoustic trauma (AAT). The overall recovery rate (full, partial, and none) is undetermined. Study design: Original case series and systematic literature review. Setting: Case series of a tertiary referral center and a systematic literature review. Methods: Cases of AAT between 2012 and 2022 were retrospectively analyzed for demographics, acoustic trauma characteristics, treatment modality and delay and prognosis. This case series was added to the series identified by a systematic literature review. This review included "Medline" via "PubMed", "EMBASE", and "Google scholar". All series were pooled for meta-analysis defining prognosis following steroidal treatment for AAT patients. Results: The pooled analyses included 662 ears, out of which 250 underwent complete recovery of hearing (overall proportion = 0.2809, 95%confidence interval [CI] = 0.1611–0.4178). Any recovery was recorded for 477 ears (overall proportion = 0.7185, 95% CI = 0.5671–0.8493) and no recovery was documented for 185 ears (overall proportion = 0.2815, 95% CI = 0.1507–0.4329). Conclusion: The rate of overall recovery for AAT is around 70%, and around 30% for full recovery when steroids are initiated within the first 2 weeks following the insult. Level of evidence: 3.

Objective: Temporal bone pneumatization (TBP) is speculated to serve as a shock absorber in temporal bone fractures (TBF), directing the fracture line away from vital structures. This study correlates TBP extent with TBF patterns and preservations of vital TB structures. Study Design: Retrospective cohort study. Setting: Tertiary referral medical center. Methods: All TBF patients referred to a single tertiary center 2017 to 2023 were evaluated. A pneumatization index score for each of their TBs was derived by counting automated‐voxel density in a 0 to 100 scale. Results were correlated to the TBF type and the violated structure(s). The ossification index was compared to previously detailed qualitative classification systems of TBP. Results: One hundred and forty‐five patients were enrolled (mean age 43 ± 17 years). Kinematics were motor vehicle accidents (46%), scooter (15%), bicycle (14%), falls (13%), and assaults (8%). The mastoid ossification index we used showed a strong correlation to all qualitative classification systems (sigmoid = 0.829; labyrinthine = 0.849; carotis = 0.863, infralabyrinthine = 0.869, all P <.001). The pneumatization index strongly correlated with capsule‐violating TBFs, with a mean of 44 ± 23 for otic capsule‐sparing TBF and 61 ± 20 for otic capsule‐violating (OCV) TBF (P <.001). The facial nerve was violated in 30 patients. Facial canal (FC) involvement was not correlated to the ossification index: it was 49 ± 23 for FC‐sparing and 44 ± 23 for FC‐violating (P =.620). Conclusion: TBP serves as a protective mechanism against OCV TBF. The more pneumatized the TB, the less likely the otic capsule will be violated in the event of a TBF with the exception of the carotid and FCs. TBP index is in strong agreement with qualitative TBP classification systems. [ABSTRACT FROM AUTHOR]

Background: This study compares early outcomes of osteofascial fibula free flap (OF‐FFF) with donor‐site primary closure and osteocutaneous (OC) FFF with donor‐site skin grafting in segmental mandibular reconstruction. Methods: A retrospective chart review of FFF mandibular reconstruction patients (2006–2022) divided into OF‐FFF and OC‐FFF groups. Clinical data, operative parameters, and early postoperative outcomes (≤ 90 days) were analyzed. Results: The study included 67 patients (39 OF‐FFF, 28 OC‐FFF). OF‐FFF had significantly lower donor‐site complications (12.8% vs. 53.6%, p < 0.001) and revision surgeries (7.7% vs. 35.7%, p = 0.004) compared to OC‐FFF. Recipient‐site (28.2% vs. 25%, p = 0.77) and flap (15.4% vs. 17.9%, p > 0.99) complications were comparable. Conclusions: OF‐FFF mandibular reconstruction with donor‐site primary closure is a safe and reliable technique associated with superior donor‐site and comparable flap and recipient‐site outcomes to OC‐FFF, thus may be considered as a viable alternative to OC‐FFF for selected patients.

Introduction: The etiology of idiopathic sudden sensorineural hearing loss (ISSNHL) remains elusive, with vascular compromise as a proposed cause. This study aimed to explore the correlation between the vertebrobasilar vascular system laterality (VBVSL) and ISSNHL laterality. Methods: We conducted a retrospective analysis of consecutive patients diagnosed with ISSNHL from 2015 to 2020. The VBVSL pattern was established via magnetic resonance imaging scans by a neuroradiologist. ISSNHL occurring contralaterally to the basilar artery (BA) curvature or ipsilaterally to the dominant vertebral artery (VA) was designated as a "positive match," with all other scenarios classified as a "negative match." Results: Our study included 191 ISSNHL patients (median age 57 years, 89 males, 93 right ears). The majority of patients did not exhibit a positive match between ISSNHL laterality and the sides of BA curvature or dominant VA (28.8% and 36.6% for BA and VA, respectively). Notably, VA-positive match patients were significantly older than VA-negative match patients (59 vs. 53 years, p = 0.043), with a similar trend observed in BA-positive match compared to BA-negative match (59 vs. 54.5 years, p = 0.057). However, there was no significant difference in any other clinical, audiometric, or outcome factors between the positive and negative match groups. Conclusion: The findings suggest no association between VBVSL and ISSNHL laterality. Furthermore, patients in the positive match group did not exhibit distinct clinical or audiometric features compared to those without a match. [ABSTRACT FROM AUTHOR]

Simple Summary: A subset of cutaneous squamous cell carcinoma (cSCC) that is associated with high-risk features carries an increased risk for aggressive disease, local recurrence, and regional metastasis, which leads to significant morbidity and mortality. The current available systems for cSCC risk stratification are considered inadequate and fail to accurately distinguish high-risk cSCC patients who can benefit from aggressive management, emphasizing a great need for an accurate metastatic risk tool for early identification of high-risk cSCC patients. A 40-gene expression profile (40-GEP) was developed to biologically distinguish high-risk tumors that would benefit from more aggressive management. This systematic review and meta-analysis aimed to evaluate the reported prognostic value and clinical utility of the 40-GEP test. The results indicated that the 40-GEP test improved cSCC risk stratification both independently and in combination with other clinicopathologic risk factors. Background: The current tumor staging systems for cutaneous squamous cell carcinoma (cSCC) are considered inadequate and insufficient for evaluating the risk of metastasis and for identifying patients at high risk of cSCC. This meta-analysis aimed to assess the prognostic significance of a 40-gene expression profile (40-GEP) both independently and integrated with clinicopathologic risk factors and established staging systems (American Joint Committee on Cancer, eighth edition (AJCC8) and Brigham and Women's Hospital (BWH)). Methods: Electronic databases, including PubMed (MEDLINE), Embase, the Cochrane Library, and Google Scholar, were systematically searched to identify cohort studies and randomized controlled trials on evaluations of the prediction value of 40-GEP in cSCC patients up to January 2023. The metastatic risk analysis of a given 40-GEP class combined with tumor stage and/or other clinicopathologic risk factors was based upon log hazard ratios (HRs) and their standard error (SE). Heterogeneity and subgroup analyses were performed, and data quality was assessed. Results: A total of 1019 patients from three cohort studies were included in this meta-analysis. The overall three-year metastatic-free survival rates were 92.4%, 78.9%, and 45.4% for class 1 (low risk), class 2A (Intermediate risk), and class 2B (high risk) 40-GEP, respectively, indicating a significant variation in survival rates between the risk classification groups. The pooled positive predictive value was significantly higher in class 2B when compared to AJCC8 or BWH. The subgroup analyses demonstrated significant superiority of integrating 40-GEP with clinicopathologic risk factors or AJCC8/BWH, especially for class 2B patients. Conclusions: The integration of 40-GEP with staging systems can improve the identification of cSCC patients at high risk of metastasis, potentially leading to improved care and outcomes, especially in the high-risk class 2B group.

Objective: To investigate the likelihood of missing a vestibular schwannoma (VS) diagnosis in patients who present with a sudden hearing loss (SHL) that does not meet the most accepted audiometric criteria for sudden sensorineural hearing loss (SSNHL) (a decrease of ≥30 dB at three consecutive frequencies). Methods: All adult patients (>18 years) diagnosed with SHL of any severity in a tertiary care referral medical center between 2015 and 2020 and who underwent an MRI scan to rule out VS were included. Statistical analyses were conducted to evaluate the difference between the rate of VS among patients with an initial audiogram, which met the abovementioned criteria, and those who did not. Other audiometric criteria for SNHL were also evaluated (≥10 dB at ≥2 frequencies and ≥ 15 dB at one frequency). Results: Of the 332 patients included in the study, 152 met the audiometric criteria for SSNHL, and 180 did not. Both groups had a similar VS rate (8.6% vs. 8.9%, p = 0.914). Similar results were found when other audiometric criteria for asymmetric SNHL were analyzed. In a subgroup analysis of patients with VS‐associated SSNHL, neither the tumor size nor the Koos classification was associated with any of the audiometric criteria systems. Conclusion: There should be a high index of suspicion for the presence of VS in patients with an SHL of any severity. Level of Evidence: 3 Laryngoscope, 133:670–675, 2023 [ABSTRACT FROM AUTHOR]

Objectives: This study investigated the impact of eustachian tube (ET) function (ETF) on therapeutic success on candidates for intra-tympanic administration of steroids (ITAoS), due to idiopathic sudden sensorineural hearing loss (ISSNHL). Methods: Medical chart review in two university-affiliated medical centers was performed. Included were consecutive adult patients diagnosed with unilateral ISSNHL between 2012 and 2019 who were treated with ITAoS due to incomplete or no recovery following systemic steroidal therapy. ETF was assessed by means tympanometry, before the initiation of ITAoS. The cohort was divided into an ET dysfunction group (ETD(+)) and a functioning ET group (control: ETD(−)). The audiologic response to treatment was recorded at the last follow-up. Results: A total of 64 suitable patients [median (interquartile, IQR) age 49 (38–63) years] were enrolled. The ETD(+) group included 20 patients and the remaining 44 patients served as controls. Demographic and clinical parameters were not significantly different between the two groups at presentation. Hearing thresholds were improved significantly better, at frequencies 250, 500, 1, 2, 4, and 8 kHz (p = 0.001–0.040) in the ETD(+) group. Conclusion: ETD(+) is associated with better efficacy of ITAoS. Level of evidence: 4. [ABSTRACT FROM AUTHOR]

Objectives: To report adverse events (AEs) associated with systemic steroid treatment in idiopathic sudden sensorineural hearing loss (ISSNHL). Material and methods: A retrospective chart review of consecutive patients newly diagnosed with ISSNHL necessitating systemic steroidal treatment was conducted from 1/2017 to 2/2021. Blood pressure (BP) was monitored three times daily and morning fasting glucose was monitored once daily during treatment. An AE was defined as a fasting blood glucose level > 160 mg/dl, systolic BP > 80 mmHg, and diastolic BP > 100 mmHg. Results: In total, 143 patients were enrolled [69 (48%) males and 74 (52%) females] of whom 29 (20%) had diabetes mellitus (DM) and 46 (32%) had hypertension (HTN). The cohort's median age (interquartile range) was 58 (37–69) years. Fifty-three patients (37%) did not complete the oral steroidal treatment due to any AE (glycemic or hypertensive). Background DM highly correlated with increased risk of a glycemic event (0.59 vs. 0.13 for diabetic and non-diabetic patients, respectively, P < 0.001). HTN correlated significantly with increased risk of an overall AE (0.54 vs. 0.29 for hypertensive and non-hypertensive patients, respectively, P = 0.001). Neither pre-treatment BP nor glucose level predicted the risk of an AE (P = 0.310 and 0.521, respectively). Conclusions: AEs due to systemic steroidal treatment are common among ISSNHL patients. Demographic and baseline values cannot predict the risk of AEs which can occur throughout the entire duration of treatment. Patients with DM and HTN are at the greatest risk of AEs. Tight blood glucose and BP monitoring are recommended during treatment. Level of evidence: 4. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the published time to extrusion of tympanostomy tubes inserted in the various quadrants of the tympanic membrane. Methods: Publications were selected by a search with 'PubMed', 'Embase' and 'Web of Science'. A meta‐analysis of time to extrusion as a function of tympanic membrane quadrant intubation was performed. Design, Setting, Participant‐Not relevant Main Outcome Measured: Extrusion rate of tympanostomy tubes inserted in the various quadrants of the tympanic membrane. Results: Eleven studies describing 2232 tympanostomy tubes were enrolled into the quantitative meta‐analysis. The extrusion rate was evaluated at 3‐month intervals up to 24 months post‐intubation, and it did not differ significantly at any of the time points tested for the superior and inferior anterior quadrants. The cumulative extrusion rates were as follows: 11 and 9%, 32 and 23%, 59 and 36%, 80 and 67%, 87 and 70%, 88 and 82%, and 96 and 89% in the superior and anterior quadrants, respectively, at 3, 6, 9, 15, 18, 21 and 24 months post‐intubation, respectively. Conclusion: Time to extrusion of tympanostomy tubes are similar for all 3 tympanic membrane quadrants. The anterior superior quadrant intubation has no superiority in terms of intubation time.

Objectives/Hypothesis: To investigate the risk of residual tympanic membrane (TM) perforation after intratympanic (IT) steroidal treatment administered via transtympanic injection compared with trans‐tympanostomy tube (TyT). Study Design: Case series, systematic review and meta analysis. Methods: Data were retrieved from the medical files of an original cohort of all consecutive patients with sudden sensorineural hearing loss necessitating IT steroidal treatment in a tertiary medical center between January 1, 2016 and November 20, 2020. A systematic literature search of "MEDLINE" via "PubMed," "Embase," and "Web of Science" on comparable published cases was performed and meta‐analysis was established. Results: Eighteen studies describing 818 ears were included in the quantitative meta‐analysis in addition to a local cohort of 140 ears. The proportion of residual TM perforation was 1.11% and 1.14% (95% confidence interval: 0.01%–3.27% and 0.028%–2.38%) in the TyT and trans‐tympanic groups, respectively, suggesting no significant difference in residual TM perforation risk between these techniques. Conclusion: IT steroid therapy via trans‐TyT is not associated with more residual perforations than IT steroid therapy via transtympanic injections.

Objectives: To characterize blast-induced cholesteatomas (BIC) in terms of symptoms, presentation, and location within the middle ear cleft (MEC). Design: A search for all English language articles in "MEDLINE" via "PubMed" and "Google Scholar" was conducted. Results: A total of 67 ears with BIC were included. Fifty-eight ears in which the traumatic perforation failed to spontaneously close were excluded, leaving seven case reports (eight patients, nine ears) for statistical analysis. Time between blast exposure to spontaneous tympanic membrane (TM) closure was 16 days to 10 months. Time between blast exposure and cholesteatoma diagnosis was 5 months to 4 years. The cholesteatomas were diagnosed due to symptoms in two ears, as asymptomatic finding on physical examination in one ear and as asymptomatic finding in axial imaging in three ears. Conclusions: BICs can develop behind intact tympanic membrane or along with TM perforation. Based on the current review, when a TM perforation and spontaneous healing were documented, after blast exposure, MRI scan is an integral component of the follow-up. The optimal timing for MRI performance after blast exposure, is yet to be identified. [ABSTRACT FROM AUTHOR]

Purpose: Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway. Methods: This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed. Results: Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1–90 days in all 8 patients with available follow-up of 1–3 months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway. Conclusions: VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFIm did not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway. Level of evidence: 4. [ABSTRACT FROM AUTHOR]

Abstract: Background: The purpose of this study was to investigate the association between isolated serous otitis media (SOM) and/or conductive hearing loss (CHL) and nasopharyngeal carcinoma (NPC) in a low‐to‐intermediate endemic area. Methods: Medical records of all adult patients (≥17 years) with SOM/CHL who underwent endoscopic‐guided nasopharyngeal biopsy to exclude NPC during a 10‐year period were reviewed. Statistical analyses were conducted to identify significant predictors for NPC. Results: A total of 195 patients were included (121/195; 62.1% men), among whom 169 (86.7%) presented with isolated SOM/CHL. Overall, 12 patients were diagnosed with NPC (12/195; 6.2%), however, only 1 patient (1/169; 0.6%) had isolated SOM/CHL. Coexisting clinical manifestations and suspicious nasopharyngeal findings on fiber‐optic nasopharyngoscopy were found to be significant predictors for NPC on univariate and multivariate analyses (P < .05). Conclusion: Patients with isolated SOM/CHL and without coexisting clinical manifestations or suspicious findings on nasopharyngoscopy may avoid a routine nasopharyngeal biopsy. [ABSTRACT FROM AUTHOR]
