Outcome of Type 1 tympanoplasty: An experience at Biratnagar eye hospital in Eastern Nepal

Abstract

Background: The history of tympanoplasty is well over a century. Type 1 tympanoplasty is an established procedure worldwide with a variation in the outcome.Aims and Objectives: To analyze the outcome of Type 1 tympanoplasty surgeries in terms of graft success and hearing improvement done at the Ear Department of Biratnagar eye hospital in eastern Nepal and discuss the various factors that might have influenced it.Materials and Methods: Retrospective analysis of records of the cases that underwent Type 1 tympanoplasty from August 2013 to January 2015 was done. The factors analysed were age, gender, the side of the affected ear and the perforation size. Appropriate Statistical test was applied and the results were discussed.Results: A total of 151 cases of type 1 Tympanoplasty were analysed were females had higher frequency than males, with higher incidence at younger age. The mean age of successful cases was 28.53. Females had a better success rate in terms of graft success compared to males. Moderate size perforations had the best outcome of graft success and least were of small size perforations. Of all cases analyzed, hearing improvement was observed in maximum cases.Conclusion: There was no significant influence of age or gender on the hearing outcome. The difference of hearing improvement according to size of perforation was also not significant.Asian Journal of Medical Sciences Vol.7(2) 2015 55-60

Evaluation of Graft Uptake in Type 1 Tympanoplasty With Dry and Wet Temporalis Fascia Graft

“…66.7% were females in group 1 with a male to female ratio of 1:2 and 76.7% were females in group 2, with a sex ratio of 1:3.3. In the study by Sanjeev Kumar Thakur et al, females were more common than males 4 , similar to our study, with a sex ratio of female: male being 1.6:1. However, other studies like Geetanjali Jaiswani and Rajesh Kumar 6 and Adnan Saleem Umar, Zubair Ahmed 7 had males more common than females.…”

“…Majority of the patients were in the age group 21 -30 years in both groups (43.3% in group 1 and 36.7% in group 2). In a study conducted by Sanjeev Kumar Thakur et al 4 on outcome of tympanoplasty, the highest frequency was of the age group 21-30 years, similar to our study. Another study by Md.…”

“…In study by Sanjeev Kumar Thakur et al, left was more (57%) than right (43%). 4 But in a study by Adnan Saleem Umar and Zubair Ahmed, right-sided CSOM was more common. 7 Both the right and left ears were nearly equally affected (right ear 51 and left ear 49 out of 100 cases) in a study by Shaikh et al 9 Majority (46.7 %) of patients in group 1 had large central perforations, whereas in group 2 large and medium-sized perforations were equally distributed (46.7% each).…”

“…Another study by Sanjeev Kumar Thakur et al found that the age factor did not influence the success rate in terms of graft success. 4 However, a recent study in Nepal Medical College by Rupesh Raj Joshi et al concluded that the graft takes rate was better with the advancing ages. 10 According to Lee and Schuknecht 19 -1971, age has no significant role in success of Tympanoplasty.…”

Graft uptake and post-operative hearing outcome with type-I tympanoplasty in dry versus wet ear: a comparative study

“…6 A study named "outcome of type 1 tympanoplasty" conducted at Biratnagar hospital in eastern Nepal showed the highest frequency of patients in the age group 21-30 years, which is similar to the results of present study. 7 The involvement of young age groups being more common indicates the fact that CSOM tends to occur more in early decades of life and resolves to leave permanent perforations with condutive hearing loss in many cases. 8 The early presentation may be due to health issues and difficulty in hearing affecting the work efficiency, leading patients to seek early medical intervention.…”
