So far, comparative evaluations of TMP with and without AML calcification have rarely been reported. The aim of the current study is to compare the hearing outcomes of TMP with and without calcificatio n of AML under transcanal endoscopic type I tympanoplasty. METHODS: Records of 67 patients diagnosed with CSOM and receiving transcanal endoscopic type I tympanoplasty were divided into the AML calcification group (Cal group, n = 31) and the non-AML calcification group (non-Cal group, n = 36). The 31 patients in the Cal group were divided into subgroup A and B according to the severity of calcification. The operation time, closure rate, and pre- and postoperative audiometric results were retrospectively collected and analyzed. RESULTS: Preoperatively, the Cal group had higher mean air-bone gap (ABG; P = .022), and ABGs at 250 Hz (P = .017) and 500 Hz (P = .008) compared with the non-Cal groups. The Cal group showed higher improvements of ABGs at 250 Hz (P = .039) and 500 Hz (P = .021) compared with the non-Cal groups postoperatively. CONCLUSIONS: The TMP with AML calcification leads to higher ABGs at low frequencies. The hearing o utcomes are similar for TMP both with and without AML calcification after surgery. Our results suggest that transcanal endoscopic type I tympanoplasty is an appropriate surgical method for TMP with AML calcification, if the lesion can be detected and completely eliminated.
