impact of cubism graft on the outcome of tympanoplasty surgery

Background: Tympanoplasty is a widely performed surgery for the repair of tympanic membrane perforation. Aim of the study: to compare the auditory and anatomical outcomes between two different techniques in tympanoplasty: the first with temporalis facia graft + the new “cubism” graft and the other with temporalis facia graft alone. Patients and methods: A prospective, randomized study was conducted in Otorhinolaryngology Head and Neck Surgery Department, Al-Azhar University Hospital (Damietta). Results: Cubism graft group wasn't significantly different to Temporalis fascia only group regarding ABG (p= 0.233). The ABG gain 3 month in Cubism graft group ranged from 14 to 17.5 with mean ± SD = 16.17 ± 1.15 while in Temporalis fascia only group the ABG gain 3 month   ranged from 10 to 16 with mean ± SD = 14.12 ± 1.91 with statistical significant difference (p= 0.005) between the two groups. Conclusion: The novel “cubism” graft technique offers many advantages. Cartilage grafts can be thinned harmlessly while obtaining a convenient additional material in this technique. This hybrid, cartilaginous dust and PRF mixture graft can be used widely in tympanoplasty. We experienced that both functional and anatomical outcomes of this graft are very satisfying.
