Success Rate of Revision Myringoplasty Using Temporalis Fascia Graft

Abstract

Background and Aim: To evaluate the success rate of revision myringoplasty using temporalis fascia graft and to assess the effect of potential influencing factors on closure of tympanic membrane (TM) and hearing outcome such as size and site of perforation, whether the patient is smoking or not and condition of contralateral ear.

Methods: Thirty patients were included in this prospective study, who underwent revision myringoplasty for chronic otitis media without cholesteatoma in the period between 2017- 2019 in the Department of Ear, Nose, and Throat-Head and Neck Surgery in Almowasat University Hospital. Data of all patients: perforation size and site, middle ear status, surgical approach, graft material, pre and postoperative morphological and functional results were assessed. The temporal fascia was used for the reconstruction of TM. The interrelation between multiple preoperative parameters and postoperative morphological (closure of the perforation) and functional (hearing level) outcomes were assessed.

Results: Successful closure rate of the TM perforation was 86.66% and failure rate was 13.34% in revision myringoplasty. The improvement of the air bone gap between 10-20 dB was 76.66% while the air bone gap between 20-30 dB was unchanged 23.33%.

Conclusion: Revision myringoplasty can offer reasonably good chances for postoperative graft healing and hearing improvement with a high success rate. This gives the patient a good benefit in protecting the ear from developing complications that may have poor structural changes in the middle ear (ossicular necrosis and tympanosclerosis) which in turn leads to hearing loss.
