 A curved bar is used for bone removal in patient who undergo transcanal endoscopic tympanoplasty;however, the conventional curved bar(CCB)does not have an irrigation system, and a complicated procedure is required for bone removal. In 2020, the irrigation system integrated curve bar(IICB)was introduced. From March 2020 to August 2021, we performed transcanal endoscopic tympanoplasty on 13 ears(IICB group:6 ears, CCB group:7 ears)with pars flaccida of cholesteatoma. The average operation time was 154 min in the IICB group and 218 min in the CCB group, which suggests that the IICB device may shorten the operation time.
