A study to compare hearing improvement of placing temporalis fascia graft medial to malleus and lateral to malleus by pure tone audiometry

Abstract

Tympanoplasty is a surgical method, to eradicate middle ear infection and improve its function. A main part of tympanoplasty is repair of perforated tympanic membrane which results mainly from chronic otitis media (COM). Other etiologies include traumatic or neoplastic defects on tympanic membrane. Ventilation tube insertion is reported the most common surgical cause of tympanic perforation. Patients with COM mucosal who presented to ENT opd, hospital who satisfy the inclusion and exclusion criteria were included in the study. Detailed history, general and ENT examination was done including otoendoscopy and tuning fork tests. Each patient underwent routine blood investigation and pure tone audiometry (PTA). There is significant hearing improvement in group A (medial) whereas there is no significant improvement in hearing in case of group B (lateral)
