[Application of two auricular cartilage-perichondrium complexes in tympanoplasty].

OBJECTIVE: To compare the effects of cartilage-perichondrium palisade complex and cartilage-perichondrium horseshoe complex in tympanoplasty for large tympanic membrane perforation. METHODS: Nineteen patients (19 ears) undergoing tympanoplasty with cartilage-perichondrium palisade complex and 20 patients (20 ears) with cartilage-perichondrium horseshoe complex were compared for postoperative hearing and closure rate of tympanic membrane perforation. RESULTS: The closure rates of the tympanic membrane were all 100% in both groups 3 months after the operation, while tympanoplasty with cartilage- perichondrium horseshoe complex resulted in significantly greater improvement of the postoperative air-bone gap in speech frequency. CONCLUSION: Both of the two auricular cartilage-perichondrium complexes produced good effects for repair large tympanic membrane perforation, but cartilage-perichondrium horseshoe complex can achieve better results in speech frequency.
