Article Abstract
Introduction: Accumulating data indicate that patients with COVID-19 could be affected by sudden sensorineural hearing loss (SSNHL). The aim of the study was to analyze the epidemiological and clinical trend of SSNHL occurrence during the COVID-19 pandemic by applying a systematic review and meta-analysis approach.
Methods: PubMed, Scopus, Web of Science, ScienceDirect, and Cochrane databases were searched.
Results: The seven included studies had adequate relevance to the topic and the quality was fair. The mean age at SSNHL onset ranged from 39.23 to 62.18 years during the pandemic year period (PYP); a meta-analysis of four studies comparing these data with those of previous periods in the same institutions found a younger age during the PYP (pooled mean -0.2848). The heterogeneity was high (76.1935%) and no frank asymmetry was observed in the funnel plot. The SARS-CoV-2 positivity rate of SSNHL patients ranged from 0% to 57.53%. Standard steroid treatments were applied without significant adverse effects. Comprehensively, hearing improvement was achieved for more than half of the cases. No studies reported long-term follow-up data.
Conclusions: Further prospective analyses on large series and a long-term follow up on COVID-related SSNHL cases are necessary to address the open questions regarding the causative link between COVID-19 infection and SSNHL.

Background: Systemic immune-inflammatory index (SII) and prognostic nutritional index (PNI) are known to predict the severity and prognosis of various diseases. However, their role in sudden sensorineural hearing loss (SSNHL) is unclear.
Methods: This study collected 100 patients with SSNHL and 100 healthy volunteers.

Sudden sensorineural hearing loss (SSNHL) is an acute hearing disorder that develops rapidly and is an otolaryngology emergency. Hyperbaric oxygen therapy (HBOT), a non‑pharmacological treatment, has gained increasing attention for SSNHL management. HBOT exerts therapeutic effects by increasing inner ear oxygen partial pressure, improving the microcirculation and reducing inflammation, as its main mechanisms.

Background And Objective: Idiopathic sudden sensorineural hearing loss (ISSNHL), which is an otologic emergency characterized by rapid-onset inner-ear hearing loss without an identifiable cause, remains a clinically urgent but poorly understood entity. While environmental factors have been proposed as potential triggers, prior studies show conflicting results. This study aimed to examine associations between weekly ISSNHL incidence and meteorological variables, including temperature, wind speed, and atmospheric pressure, in a Mediterranean city over a six-year period.

Objective: Clinically significant prognostic indicators have not been identified for sudden sensorineural hearing loss (SSNHL). Consequently, this research aimed to evaluate the effectiveness of iron parameters in predicting prognostic outcomes for patients with SSNHL.
Methods: Ninety-one individuals with SSNHL were prospectively enrolled and received steroid treatment at a dosage of 1 mg/kg/day for two weeks.
Introduction: Cochlear implantation (CI) may be used as a viable method for restoring hearing in patients with sensorineural hearing loss (SNHL) caused by jugular foramen tumors.
Materials And Methods: 42-year-old female presenting with sudden-onset SNHL, pulsatile tinnitus, and otalgia, with a PTA of 119 dB and AzBio sentence score of 0% in quiet. Brain MRI identified a 22 mm tumor within the left jugular foramen and hypoglossal canal involving the cochlear aqueduct.
