Application of two auricular cartilage-perichondrium complexes in tympanoplasty / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effects of cartilage-perichondrium palisade complex and cartilage-perichondrium horseshoe complex in tympanoplasty for large tympanic membrane perforation.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
