Assessment of Eustachian tube functioning following surgical intervention of Oral Submucus Fibrosis by using tympanometry & audiometry

Oral Submucus fibrosis has been reported to cause variation in hearing sensitivity & changes in middle ear function. This study was conducted to validate the influence of OSMF and its surgical correction on middle ear function and hearing sensitivity. In this study, 20 patients (40 ears) suf...

description Oral Submucus fibrosis has been reported to cause variation in hearing sensitivity & changes in middle ear function. This study was conducted to validate the influence of OSMF and its surgical correction on middle ear function and hearing sensitivity. In this study, 20 patients (40 ears) suffering from biopsy proven OSMF (Group 2 & 3) were tested for Middle ear dysfunction and hearing sensitivity using Tympanometry & Audiometry. On Tympanometry, Type A curve was obtained in 29 ears, Type B curve in 11 ears preoperatively. Immediate postoperatively TYPE A curve was obtained in 27 ears, TYPE B curve in 13 ears. After 1 month and 3 month Type B curve was not obtained in any ear. On Audiometry,28 ears showed normal hearing and 12 ears showed minimal conductive hearing loss preoperatively and Immediate postoperatively. Tests after 1 month and 3 months showed all 40 ears having normal hearing. Results were found statistically significant with p value 0.000 and F value of 11.331 in Tympanometry and 11.143 in Audiometry. Pearson correlation test revealed that results from both the test are highly co related (0.902). OSMF causes fibrotic changes in paratubal muscles which in addition with restricted mouth opening hampers proper Eustachian tube functioning in turn causing changes in Middle ear function. This feature is seldom/infrequently found in Group 2 and 3 and if encountered can be dealt effectively with surgical intervention.
