Comparative study of tympanoplasty type I using periosteum versus tragal cartilage with perichondrium

Abstract

Abstract Background Various grafting materials and different techniques have been used for myringoplasty. The aim of the study was to compare the result of tympanoplasty in patients with safe-type chronic suppurative otitis media using periosteum versus tragal cartilage with perichondrium grafts through pre- and postoperative clinical and audiological evaluation. Results There was statistically significant difference for mean air-bone gap for group A (23.4 dB ± 0.03 SD) when compared to group B (19.4 dB ± 4.2 SD) with P value 0.103. Also, there was statistically significant difference in the hearing gain in group A after 6 months (25.53 dB ± 6.26 SD) when compared to group B (19.63 dB ± 9.76 SD) and the P value was 0.003. Graft taken was superior in the periosteal group (95%), compared to the cartilage grafts (90%). Conclusion Tympanoplasty with periosteal graft showed better hearing results and high rates of graft taken than tragal cartilage grafts.
