A Different Cartilage Graft Technique: Perichondrium-Preserved Palisade Island Graft in Tympanoplasty.

Various graft materials have been used since tympanoplasty technique was first described. In this study, the authors aimed to share our modified island cartilage graft technique.A total of 47 ears of 46 patients on whom tympanoplasty or tympanomastoidectomy operation was performed in our clinic because of chronic otitis media were included in the study.Mean preoperative air-bone gap of the patients was 32.25 ± 11.85 dB and mean postoperative air-bone gap was 19.25 ± 10.46 dB. The difference was statistically significant (P < 0.001). When all the patients were evaluated, preoperative and postoperative air conduction pure tone audiometry values were 43.38 ± 14.74 dB and 32.61 ± 15.62 dB, respectively. The difference was statistically significant (P < 0.001). Graft success rate in terms of perforation closure was found to be 44/47 (93.61%).Our modified island cartilage graft technique is easy to apply and its graft success rate and hearing results are good.
