Abstract :

Chronic suppurative otitis media is defined as a chronic infection of the mucosa lining the middle ear cleft. Middle ear cleft include the eustachean tube, hypotympanum, mesotympanum, epitympanum, aditus and mastoid air cell system. Upper part of middle ear has an important opening known as the aditus ad antrum. Which communicates the epitympanic recess with the mastoid antrum. It is very important for the aeration of the mastoid air cells. Studies shown that obstruction of the aditus ad antrum is related with pathogenesis of CSOM. In tubotympanic type of CSOM obstruction of aditus occours most commonly with granulation tissue, edematous mucosa, tympanosclerosis and rarely with mucous memane. Aim of our study is to find out aditus mucous memane curtain blocking aditus and compromising mastoid ventilation, as a cause of post–aural pain in radiologically normal looking mastoid with no sign of any inflammatory reaction, and intraoperatively without any sign of retraction.
