Abstract
A retrospective study was conducted at a tertiary ENT care hospital with following aims, methodology and results: (1) To know the incidence of tympanosclerosis. (2) To classify tympanosclerosis surgically as well as histologically. (3) To know the long term hearing outcome of Tympanosclerosis surgery. It is a retrospective study at an ENT Hospital Centre in eastern India. Hospital ethical board clearance was duly obtained. All cases of tympanosclerosis were documented with special reference to surgical procedure, areas of involvement and postoperative hearing outcome. In this study, 90 cases of tympanosclerosis was found in 1880 cases of tympanomastoidectomies in 8years and had been divided into (1) Myringosclerosis (60 cases, 66.6%), (2) Ossicular Tympanosclerosis without involvement of footplate (23 cases, 25.6%), (3) Ossicular Tympanosclerosis with involvement of footplate (7 cases, 7.8%). Treatment options included osssicular mobilization keeping ossicular integrity and mobility, Total or partial ossicular prosthesis after removal of incus & stapes suprastructure, stapedectomy with Long malleus-footplate piston. Overall good hearing outcome (i.e., postoperative air-bone gap less than 20dB) was noticed in 85.5% of cases of Tympanosclerosis. Removal of tympanosclerosis with keeping the osssicular chain intact is the key to success; results are not favourable if footplate is totally fixed with disease.
