INTRODUCTION

Chronic suppurative otitis media (CSOM) is one of the most common childhood infectious diseases worldwide and is a common cause of hearing impairment in resource-limited settings, although it is less frequently seen in resource-rich settings [1]. It is characterized by chronic drainage from the middle ear associated with tympanic membrane (TM) perforation (picture 1) [2,3]. CSOM is often preceded by an episode of acute otitis media (AOM).

The epidemiology, pathogenesis, clinical features, diagnosis, and management of CSOM are reviewed here. The prevention, treatment, and complications of CSOM are discussed in detail separately. CSOM in the setting of tympanostomy tubes is also reviewed separately. (See "Chronic suppurative otitis media (CSOM): Treatment, complications, and prevention" and "Tympanostomy tube otorrhea in children: Causes, prevention, and management".)

AOM, otitis media with effusion, and cholesteatoma in children, and acute and chronic otitis media in adults are reviewed separately:

(See "Acute otitis media in children: Epidemiology, microbiology, clinical manifestations, and complications".)

(See "Otitis media with effusion (serous otitis media) in children: Clinical features and diagnosis".)
