Abstract:ObjectiveTo study the establishment of a new surgical procedure of myringoplasty for tympanic membrane perforation by applying pressed graft of subdermal tissue of external auditory canal.Methods65 patients (69 ears) with tympanic membrane perforation (diameter≥3 mm and with stenosis or bend of external auditory canal) caused by otitis media or trauma received myringoplasty with this surgical procedure.ResultsThe closure rate of tympanic membrane perforation was 97.1% (67/69), and the mean healing time was 15.2 days. After following up 0.5 to 3.5 yeas postoperatively, no reperforation of tympanic membrane was recorded. Postoperative pure tone test showed 18.6 dB improvement of AC and 16.8 dB improvement of ABG on average in 66 ears, and no improvenment in 3 ears. This procedure resulted in significant improvement of hearing (ABG within 20 dB) by 95.7% (66/69).ConclusionWith advantages of simplicity in graft obtainment, expansion of surgical field by widening and straightening external auditory canal, short healing time and high healing rate of perforation, this new surgical procedure is appropriate for those patients with large perforation or/and narrow, curved external auditory canal.
