Comparative Study Between Single Layer and Double Layer Graft Technique in Tympanoplasty for Subtotal Tympanic Membrane Perforation

Abstract Introduction Tympanoplasty is the main treatment of mucosal type chronic suppurative otitis media. Objective The aim present study was to compare clinical outcomes in terms healing and audiological two groups. authors used single layer graft (perichondrium with cartilage island) one group double grafts island composite plus temporalis fascia) were second group. Methods Forty patients complained media safe subtotal perforation subdivided into first author single-layer perichondrium (composite graft) while form perichondrium/cartilage fascia. Results There no significant difference mean Air bone gap (ABG) between pre- post-operative audiometry subjects who had tympanoplasty. a ABG postoperative differences tympanoplasty Also, there tympanic membrane Conclusion by (temporalis fascia tragal cartilage/perichondrium) achieved considerable improvement ™ lower risk for residual or rejection.
