Clinical Study of Hearing Outcome After Type-I Tympanoplasty Using Temporalis Fascia as Graft

Abstract

Background
Chronic suppurative otitis media is a longstanding infection of the middle ear cleft characterized by persistent or recurrent aural discharge, deafness and perforation of tympanic membrane. Type I tympanoplasty is a surgical procedure that corrects tympanic membrane perforation.
Methods
Prospective study conducted on sixty-two patients of Chronic otitis media, mucosal type who underwent type I tympanoplasty in College of Medical Sciences, Bharatpur, Chitwan during a period of one year. Pure tone audiometry of the patients was done before the surgery and one month and three months following surgery and the hearing improvement was assessed in each case. P values were calculated by applying t test.
Results
In this study, graft uptake was highest (95%) in posterior perforations, 75% in anterior perforations and lowest (63.64%) in combined perforations. The mean hearing improvement one month following surgery was 7.16 dB and three months following surgery, it was 7.78 dB.
Conclusions
Chronic otitis media is a treatable cause of hearing loss. Type I tympanoplasty is a safe and effective method to remove the disease of the middle ear and reconstruct the tympanic membrane perforation.
