The outcome of type I tympanoplasty in patients with chronic otitis media

Abstract

Background. Tympanoplasty type 1 is a reconstruction of tympanic membrane perforation with an examination of the middle ear to ensure normality. Aim. Assess the effect of the age of the patient, site, and size of tympanic membrane perforation on hearing gain and graft uptake in patients with chronic otitis media. Patients and method. Thirty patients with type 1 tympanoplasty aged between 10 years and 50 years. Patients had been submitted for audiological tests and examination pre-operatively and at 1, 3 and 6-month intervals postoperatively. Results. Improvement was 57% in 10-25 years, 59% in 25-40 years, and 56% in 40-50 years. While graft uptake was 90% in the three groups. Hearing improvement in anterior perforation was (60%), ost. perforation (41.5%), inferior perforation (43%). While the take rate is 100% in the post, perforation, 80% in anterior perforation and 83.3% in inferior perforation, hearing gain was 40% in large perforation, 66% in medium size and 77% in small size. While the take rate in small perforation was 100%, in medium perforation 90% and large perforation 80%. About 70% of patients had closure of the air-bone gap to within 15 dB and 83 % to within 20 dB. Conclusion. Age had no impact on hearing gain and graft uptake. Size of perforation affects hearing gain and graft uptake where they are better in small and medium size perforation than large perforation. The site of perforation affects hearing gain and graft uptake where hearing gain was better in anterior perforation, while graft up was better in posterior perforation.
