El protocolo optimizado de la oxigenoterapia hiperbárica para la pérdida auditiva neurosensorial súbita

Abstract

Sudden sensorineural hearing loss (SSNHL) is defined as an acute hearing loss of >30 decibels (dB) at three consecutive frequencies, with an abrupt onset (within 3 days). The incidence of SSNHL was estimated to range from 5 to 27 per 100,000 people per year. Many studies have reported that the spontaneous recovery rate of SSNHL is 32–65%; however, this may be an overestimation. Considering that the possibility of spontaneous recovery cannot be predicted and the chance for recovery decreases with increasing delay in treatment, patients tend to start treatment early rather than waiting for spontaneous recovery. Although the cause remains unidentified in most cases, various etiologies have been proposed, including vascular compromise, viral infections, immune-mediated factors, and cochlear.
