Objective:
To determine the outcomes of tympanoplasty surgery using porcine-derived small intestinal submucosa.
Method:
A retrospective audit was conducted in a hospital setting. Thirty-five adult and paediatric patients who received a small intestinal submucosa graft as part of tympanoplasty surgery were retrospectively reviewed. Patients underwent either simple tympanoplasty (n = 26) or complex tympanoplasty as part of a concurrent otological procedure such as atticotomy and mastoidectomy. The main outcome measures were rate of tympanic membrane closure and change in four-frequency mean air-bone gap.
Results:
Thirty-one patients had a follow-up period of longer than two months. Closure was obtained in 22 patients (71 per cent). The mean air-bone gap improved from 20.7 to 12.3 dB HL in the simple tympanoplasty group and from 22.3 to 12 dB HL in the complex tympanoplasty group.
Conclusion:
Tympanoplasty surgery with small intestinal submucosa is a viable option for patients where autologous graft is not available or in order to minimise donor site morbidity.
