Introduction: The mainstay of treatment for idiopathic sudden sensorineural hearing loss (SSNHL) includes oral steroids, intratympanic steroid injections or a combination of both. The National Institute for Health and Care Excellence, in their recent hearing loss guidelines, highlighted the paucity of evidence assessing the comparative effectiveness of these treatments; and the National Institute for Health Research (NIHR) Health Technology Assessment Programme has since released a commissioned call for a trial to identify the most effective route of administration of steroids as a first-line treatment for idiopathic SSNHL. For such trials to be run effectively, reliable information is needed on patients with SSNHL: where they present, numbers, demographics, treatment pathways, as well as outcomes. This study will collect these data in a nationwide cohort study of patients presenting with SSNHL across 97 National Health Service (NHS) trusts. The study will be delivered through ear, nose and throat (ENT) trainee networks, the NIHR Clinical Research Network (CRN) Audiology Champions and the NIHR CRN. Importantly, this study will also provide a dataset to develop a prognostic model to predict recovery for patients with idiopathic SSNHL. The study objectives are to: (1) map the patient pathway and identify the characteristics of adult patients presenting to NHS ENT and hearing services with SSNHL, (2) develop a prognostic model to predict recovery for patients with idiopathic SSNHL and (3) establish the impact of idiopathic SSNHL on patients' quality of life (QoL).
Methods And Analysis: Study design: national multicentre prospective cohort study across 97 NHS trusts.
Inclusion Criteria: adult patients presenting to NHS ENT and hearing services with SSNHL.
Outcomes: change in auditory function; change in QoL score.
Analysis: multivariable prognostic model, using prespecified candidate predictors. Mean change in QoL scores will be calculated from initial presentation to follow-up.
Ethics And Dissemination: Health Research Authority and NHS Research Ethics Committee approved the study. Publication will be on behalf of study sites and collaborators.
Trial Registration Number: ClinicalTrials.gov Registry (NCT04108598).

Introduction: Sudden sensorineural hearing loss (SSNHL) is idiopathic in 70-90% of cases with 10-30% linked to vascular injuries, viral infections, or autoimmune inner ear disease (AIED). AIED contributes to less than 1% of all hearing losses, categorized into primary, affecting only the inner ear, and secondary, associated with systemic autoimmune diseases (SAID). This study examines the prevalence and features of AIED in SSNHL in a tertiary referral center.

Introduction: Based on clinical practice guidelines, the application of corticosteroids as a first-line therapy is common. Although sudden sensorineural hearing loss (SSHL) etiology is primarily idiopathic, hearing loss can result from a perilymphatic fistula (PLF). Recent findings show evidence of a specific rate of PLF based on a cochlin-tomoprotein (CTP) detection test.

Article Synopsis
- The study investigates the effects of combining hyperbaric oxygen therapy (HBOT) with steroid treatment on patients suffering from sudden sensorineural hearing loss (SSNHL).
- It involved 50 participants who received intravenous steroids and underwent HBOT, with improvements in hearing observed across various frequencies after treatment.
- Results indicated significant enhancement in hearing, particularly at lower frequencies, suggesting that the combination therapy is effective for SSNHL patients.

Objectives: Hearing recovery following idiopathic sudden sensorineural hearing loss (ISSNHL) is influenced by various prognostic factors, and the presence of acute vestibular syndrome (AVS) may adversely impact auditory outcomes. Evaluating vestibular function in SSNHL patients could offer insights into predicting hearing recovery. This systematic review aims to assess whether the presence of AVS exacerbates the audiological prognosis of ISSNHL.
