Abstract
We describe a novel myringoplasty procedure. We placed a separated fascia graft descending from the scutum, combined with underlay myringoplasty, to support an anterosuperior perforation. We reviewed data from patients who underwent myringoplasty procedures to treat perforations extending into the anterosuperior quadrant of the pars tensa from October 2012 to June 2014. A total of 42 patients who were followed for a minimum of 1 year were enrolled. The same technique was used in all operations. The tympanomeatal flap was elevated from the neck of malleus up to the tip of the lateral process of malleus. The anterior mallear fold was incised to create an opening running from the neck of the malleus to the anterior tympanic spine. A separate temporal fascia graft (complementary graft) was next inserted through the opening and pushed down into the protympanum. The upper part of the fascia graft was placed over the superior bony wall of the canal. Underlay myringoplasty was then performed. The inferior part of the fascia graft was next spread out to cover the lateral surface of the underlying graft. We measured graft take rate and preoperative and postoperative hearing parameters. The graft success rate was 97.7 % (41/42 patients). The preoperative air-bone gap was 22.56 ± 18.12 dB, and the postoperative air-bone gap was 8.4 ± 10.05 dB. This difference was statistically significant (P < 0.001). We believe that this myringoplasty technique is a safe, suitable, and effective for cases with tympanic membrane perforations extending into the anterosuperior quadrant of the pars tensa.
