Mediolateral graft tympanoplasty for anterior or subtotal tympanic membrane perforation. Export

@article{citeulike:6082023, abstract = {OBJECTIVE: To describe and evaluate the mediolateral graft tympanoplasty for the reconstruction of anterior or subtotal tympanic membrane (TM) perforation. STUDY DESIGN AND SETTING: Retrospective study of 100 patients who underwent the mediolateral graft tympanoplasty at community and tertiary care centers from 1995 to 2001. All patients underwent preoperative and postoperative audiograms. Posterior tympanomeatal flap is elevated same as in the medial (underlay) graft tympanoplasty. Anterior-medial canal skin is elevated down to the annulus. At the annulus, only squamous epithelial layer of TM is elevated up to anterior half of the TM perforation. Temporalis fascia is grafted medial (underlay) to the posterior half of the perforation and lateral (overlay) to the anterior half of the de-epithelialized TM perforation, up to the annulus. Anterior canal skin is rotated to cover the fascia graft and TM perforation as a second-layer closure. Patients were followed for at least 6 months. Outcome was considered successful if the TM is intact. RESULTS: There were 3 failures (97\% success rate), attributable to a postoperative infection, anterior blunting, and recurrent cholesteatoma, respectively. There was no significant postoperative hearing loss compared with preoperative hearing. More than 70\% of the operated ears had hearing improvement of 0-40 dB (0-10 dB in 19\% of ears, 11-20 dB in 44\%, 21-30 dB in 7\%, and 31-40 dB in 4\%) even without ossiculoplasty. With ossiculoplasty using either partial ossicular replacement prosthesis (PORP, 15\%) or total ossicular replacement prosthesis (TORP, 11\%), there were various degree of hearing improvement from 11 to 30 dB. CONCLUSION AND SIGNIFICANCE: The mediolateral graft method is superior to the traditional medial or lateral graft technique for the reconstruction of large anterior or subtotal TM perforation. This new method should help otologic surgeons to improve outcome of tympanoplasty for anterior or total TM perforation.
