Management of Chronic Suppurative Otitis Media and Hearing Outcomes at Lagos Island General Hospital, Lagos State

Chronic suppurative otitis media is a leading preventable cause of hearing impairment in Nigerian children and adults, and its management in urban secondary and tertiary hospitals in Lagos State reflects both the availability of otorhinolaryngology services and the socioeconomic profile of patients. This study examines the management patterns and hearing outcomes of patients with chronic suppurative otitis media at Lagos Island General Hospital over a four-year period from 2019 to 2022. A retrospective cross-sectional design is applied to ENT clinic registers and audiological assessment records. Variables include patient age, sex, duration of ear discharge, presence of cholesteatoma, pre-treatment audiometry findings, treatment modality (medical or surgical), surgical technique where applicable, and post-treatment audiometric outcomes. SPSS is used for statistical analysis. Available ENT literature from South West Nigeria identifies unsafe CSOM with cholesteatoma as the subtype associated with the worst hearing prognosis and the highest risk of intracranial complications. The Staging System for Chronic Otitis Media and the WHO grades of hearing impairment guide classification. Findings will support the ENT unit in implementing standardised audiometric follow-up protocols and strengthening surgical audit for mastoidectomy procedures.
