英文摘要 | BACKGROUND: To investigate the hearing outcomes of malleus preserved ossiculoplasty in type-III and type-IV tympanoplasty using Polycel prosthesis.METHODS: The technique includes the preservation of malleus, bridging the Polycel prosthesis of stapes head or footplate with malleus, and local overlay of fascia graft in the area of malleus. The eight participants (6 F, 2 M) with chronic otitis media underwent tympanoplasty and ossiculoplasty with partial or total ossicular replacement of prosthesis from March 2005 to November 2008. The pre-operative and postoperative pure-tone hearing thresholds and air-bone gap were collected and compared.RESULTS: The post-operative pure-tone averages were 40.8 dB HL and were significantly better than the pre-operative pure-tone averages of 59.6 dB HL (p < 0.05, paired sample t-test). The post-operative improvement of hearing was most significant for the audiometric frequencies of 250 Hz, 500 Hz and 1000 Hz (p < 0.05, paired sample t-test). The mean ABG was also reduced significantly from 44.9 dB to 26.4 dB post-operatively (p < 0.05, paired sample t-test).CONCLUSIONS: The malleus preserved ossiculoplasty provided a good surgical result and hearing result. The post-operative hearing gains were most significantly for the low frequencies of 250 Hz, 500 Hz, and 1000 Hz. |
