Hearing Loss in Tympanosclerosis

OBJECTIVES To study hearing loss in tympanosclerosis with intact membrane MATERIALS AND METHODS 30 cases of tympanosclerosis with intact tympanic membrane in age15-50 year. Clinical and audiological evaluation done. The involvement of tympanic membrane and degree of hearing loss noted. RESULTS 30 patients 16 male and 14 female. Agewise 15-20 yrs, 21-30yrs, 31 -40 yrs, 41-50yrs was 5, 17, 5, 3cases respectively. According to the site, anterosuperior -4, anteroinferior - 6, posterosuperior 5, , posteroinferior - 4, anterior 04, posterior 3, inferior 03, and whole tympanic membrane- 1 Tuning fork test 20 had conducting hearing loss and 10 had normal hearing. On PTA, anterosuperior 18-20 db, anteroinferior 20-30 db, posterosuperior 20 -40 db, postero inferior 20-30 db, anteriorly 20-30 db, posteriorly 30-40db, inferiorly 20-30db and whole tympanic membrane 40db conducting hearing loss. CONCLUSION Conductive hearing loss occur with myingosclerosis. common age group is 21-30 years. tympanosclerosis maximum in anteroinferior quadrant, maximum hearing loss with posterosuperior, posterior and whole tympanic membrane.
