Adhesive Otitis Media—Its Classification, Etiology and Management—

Abstract

In the present report, we described and discussed our difinition, classification, etiology and surgical managements of adhesive otitis media. Adhesive otitis media was classified into three types ; the total adhesive type, the posterosuperior adhesive type and the fibrous adhesive type. Surgical managements consisted of wall-down mastoidectomy and with cavity obliteration with bone for the total adhesive type and wall-up mastoidectomy and tympanoplasty for the posterosuperior adhesive type have been employed in this series. For prevention of re-adhesion of the drum to the promontrium, lyophilized homograf t dura and hydroxyapatite ossicular prosthesis were used. In canal wall-up technique, postoperative hearing result was successful in 81.5% and the new tympanic membrane was nearly normalized in 72.7%. In canal wall-down technique postoperative hearing result was successful in 65.1%.
