Abstract
ObjectivesTo evaluate the anatomic and functional outcomes of type1 tympanoplasty with endoscopic modified butterfly cartilage-perichondrium technique. MethodsIn our modification, perichondrium was elevated circumferentially till the attached part of the composite graft was approximately same size and shape of the perforation, cartilage was trimmed based on the perforation but 0.5 mm larger. Cartilage portion of the graft was placed medial to the edge of the perforation, then perichondrium was rolled out and draped on the circumferential raw surface of remaining tympanic membrane around. ResultsAt 4 months postop, the anatomic integrity rate of the tympanic membrane perforation for small & medium sized perforation and large sized perforation group were 100 % and 94 % (p > 0.05). For the small & medium perforation group, the mean pre and 4 months postop ACs were 30 ± 8 dB and 18 ± 6.4 dB (p < 0.01). The mean pre and 4 months postop ABGs were 19 ± 11 dB and 9 ± 3 dB (p < 0.01). For the large perforation group, the mean pre and 4 months postop ACs were 43 ± 12.5 dB and 21.5 ± 7 dB (p < 0.01). The mean pre and 4 months postop ABGs were 34 ± 8.5 dB and 12.5 ± 6 dB (p < 0.01). The differences of mean 4 months postop ACs and mean 4 months postop ABGs between the two groups were not significant (p > 0.05). ConclusionsCompared to the conventional inlay butterfly cartilage tympanoplasty technique, large or marginal perforations can be sealed more securely by this modification.
