Abstract

Chronic mucosal diseases of middle ear cleft or chronic suppurative otitis media has been traditionally defined as a chronic inflammation of the middle ear and mastoid usually associated with perforation of the tympanic membrane and otorrhoea. Understanding the pathology and pathogenesis of chronic suppurative otitis media is important in predicting the management, prognosis and sequelae of the disease. The present prospective study was conducted to evaluate the clinical, intraoperative and histopathological changes in middle ear cleft. 100 patients diagnosed with CSOM who underwent surgery were taken. The mucosa and granulation tissue was removed along with ossicles wherever indicated and sent for histopathological examination. On clinical examination, 72 cases were found to be of tubotympanic type and 28 cases of atticoantral variety. However, intraoperatively, of the tubotympanic cases 8 were found to be of unsafe type which was also proven histologically. Stratified squamous epithelium was revealed in most of the cases accompanied by changes in the submucosa. Ossicular chain was involved in 40 cases with incus being the commonest bone to be eroded.
