Type I tympanoplasty with island chondro-perichondral tragal graft: the preferred technique?

Objective:This retrospective, comparative study aimed to assess anatomical and functional results in a group of adults undergoing type I tympanoplasty for subtotal tympanic membrane perforation, using two different types of graft.Subjects and methods:The study included 106 patients affected by chronic otitis media, who underwent underlay type I tympanoplasty, 53 using an autologous chondro-perichondral tragal graft and 53 using temporalis fascia. Anatomical and functional outcomes were evaluated over time.Results:Audiometric results comparing the cartilage and fascia groups at six months and one year after surgery showed no statistically significant differences. Assessment of anatomical outcomes indicated a greater number of complications in the fascia group.Conclusion:Functional results indicate the validity of the cartilage tympanoplasty, while anatomical results indicate a slightly better outcome in terms of graft re-perforation and retraction, compared with temporalis fascia at one-year follow up. These results suggest that the cartilage technique is preferable for type I tympanoplasty.
