Abstract:

Objective      To investigate the applications of tubed pedicle tunnel skin flap of the temporalis fasciae and its supportive role in tympanoplasty.  Methods      96 lesions less otitis media ears, pedicled temporalis myofascial flap was used to repair the tunnel film material tympanoplasty I in 46 ears, the other 50 ears used tympanic membrane free temporal fascia, in contrast; select lesions in heavier ear otitis media 73, 23 of which were in the ear canal wall and then were removed to pedicled temporalis fascia flap as a tunnel film canal wall soft support, the other 50 lines had mastoidectomy of ear to make a comparison. Results      After six months of follow-up, the transfer tunnel pedicled temporalis myofascial flap graft healed well, the group survival rate was 97.8% and the free temporal fascia group was 88.0%, after raising similar hearing. The pedicled temporalis myofascial flap for canal wall cases of soft-stent group after six months of dry ear had a rate of 91.3%, radical mastoidectomy dry ear rate was 92.0% for six months, six months after hearing the former than the latter increase, line t test prompted a difference. Conclusion     The tubed pedicle skin slap of the temporalis fasciae can serve as a good patch or pedestal in tympanoplasty.
