A comparative study of using temporalis fascia autograft and dehydrated temporal fascia homograft in tympanoplasty

Background The objective of the present study was to compare the results of tympanoplasty operations performed using autograft temporalis fascia with those of dehydrated temporalis fascia homograft.

Methods This prospective study was conducted in the department of ENT of Pacific Medical College and Hospital, Udaipur in duration from February 2014 to January 2015. The study included 90 patients of chronic suppurative otitis media with dry, central perforation of tympanic membrane. The patients were divided into two groups with 45 members in each group. In group A, temporalis fascia autograft was used and in group B, dehydrated temporalis fascia homograft was used for tympanoplasty. Results were evaluated in terms of graft uptake rate and hearing improvement.

Results There were 50 male and 40 female patients in the study. Most of the patients (43.33%) were of the age group 21-30 years, followed by age group 31-40 years (24.44%). Post-operatively, 95.55% patients in group A and 91.11% patients in group B showed successful graft uptake. Mean preoperative AB gap in group A patients was 31.46±6.78 dB which was reduced to 13.01±5.61 dB postoperatively. Similarly, in group B patients, AB gap was reduced from 29.81±5.99 to 12.92±6.01 dB postoperatively. No statistically significant difference was observed between groups while comparing pre and postoperative AB gap.

Conclusions The results of tympanoplasty done by using either homograft or autograft were the same so dehydrated temporalis fascia homograft can be used as an alternative graft material with the same success rate wherever possible with the advantage of reduction in duration of surgery.
