Rates of success in hearing and grafting in the perichondrium-preserved palisade island graft technique

Introduction: Various graft materials have been used in the tympanoplasty technique. Cartilage grafts are being used increasingly in recent years. Objective: The aim of this study was to present the comparative outcomes of the perichondrium-preserved palisade island graft technique previously defined by ourselves. Methods: We retrospectively compared the hearing and graft success rates in 108 patients with chronic otitis media, who had undergone cartilage tympanoplasty, where both island and perichondrium-preserved palisade graft techniques were used. Results: The success rates among the study and the control groups with regard to graft take were 97% and 93%, respectively. No significant difference was observed between the groups with regard to the postoperative mean pure tone values, improvement in air-bone gaps and reduction in air-bone gaps to under 20 dB. However, better results were observed in the study group. Conclusion: The perichondrium-preserved palisade island graft technique is an easy method with high graft success rates and hearing outcomes.
