Audiological Outcomes of Type 1 Tympanoplasty done with Fibrin Glue

Mohanty S and Kurian AT

Introduction: The aim of this study was to assess the audiological outcomes of type 1tympanoplasty done with fibrin glue by comparing the pre and post-operative pure tone average.

Materials and Methods: Thirty three patients who were diagnosed to have chronic otitis media mucosal type and underwent type 1tympanoplasty with fibrin glue in the department of ENT of a tertiary care hospital between August 2014 and September 2015 were followed up for six months. Pre and post-operative pure tone averages were noted. Post operatively pure tone averages were noted at the third and sixth month follow-up.

Results: A total of thirty three patients underwent the procedure. The pre op mean pure tone average was 34.45dB which improved to 24.55dB three months after the surgery and to 21.73dB six months after the surgery. Pre operatively 66.7% of the patients had a hearing loss of more than 31dB and only 3% had a hearing loss of less than 20dB, where as post operatively only 15.1% had a loss of more than 31dB and 48.5% had a loss of less than 20dB. One case of graft displacement was seen.

Conclusion: The learning curve in using fibrin glue in tympanoplasty is not very steep and can be easily mastered. Through our study we have observed that using fibrin glue provides good hearing outcomes post-operatively and can be used especially in patients with large perforations to assure good hearing outcomes with graft uptake rates comparable to conventional methods.
