Tympanoplasty using the interlay fashion has infrequently been reported in transcanal endoscopic observance surgery, unlike the underlay fashion. This is because numerous surgeons find it challenging to detach the epithelial subcaste of the tympanic membrane using only one hand. still, the epithelial subcaste can be fluently detached from the inferior part of the tympanic membrane. Another crucial point is to laboriously ameliorate anteroinferior visibility indeed if the protuberance is slight because utmost perforations and postoperative reperforations are set up in the anteroinferior quadrant of the tympanic membrane. We report the operation of the interlay fashion in endoscopic tympanoplasty type I for tympanic perforations.
We retrospectively reviewed the medical records of 51 cases who had experienced tympanoplasty using the interlay fashion without ossiculoplasty between 2017 and 2020. We also compared the data with those of cases who passed bitsy surgery( MS) using the underlay fashion between 1998 and 2009( n = 104). No other fashion was used in each group during this period. form of tympanic membrane perforation and hail issues were assessed for> 1 time postoperatively.
