Abstract

Abstract : Objective: To calculate the incidence of sensorineural hearing loss (SNHL; pure or as part of a mixed hearing loss, MHL) among bullous myringitis (BM) patients with a coexisting HL to assess whether steroidal treatment should be initiated even before the findings of a formal audiogram are available. Methods: Retrospective medical record review in a tertiary referral center and systematic review of the English literature. Results: The medical records of 81 patients with BM were retrieved among whom 50 patients (62%) had actually sustained a HL, although only 39/81 patients reported a HL when asked. Twenty-four patients had a MHL, 18 had a SNHL, and eight had a conductive HL (CHL). The systematic review included 106 ears: 17 had no HL, 53 had a MHL, 20 had a SNHL, and 16 had a CHL. The combined published and current results yielded a SNHL and MHL rates of 38/139 (27%) and 77/139 (55%), respectively of all BM patients with confirmed HL. Conclusion: BM is intuitively associated with a CHL resulting from the impeded function of the affected middle ear. Medical history and physical examination are not sufficient to exclude a SNHL in BM patients, and formal audiometry is mandatory for exclusion/confirmation in this setting. Nevertheless, steroidal treatment should not be delayed until the performance of formal audiometry because the actual rate of pure CHL in this setting is very low.
