Abstract | OBJECTIVES: METHODS: The patients were performed surgeries for the first time by a senior otosurgeon from 2009 to 2022 and were performed CWD mastoidectomy with type II tympanoplasty in one stage were enrolled. Patients who could not be followed up were excluded. Titanium PORP or conchal cartilage was used for ossiculoplasty. When the stapes head was intact, a cartilage 1.2-1.5 mm thick was attached directly to the stapes; when the head of the stapes was eroded, a 1 mm high PORP and cartilage of .2-.5 mm thick were placed on the stapes simultaneously. RESULTS: 148 patients were included in the study in total. The titanium PORP and conchal cartilage groups showed no statistically significant differences at 500, 1000, 2000, and 4000 Hz considering the number of decibels of closure of the air-bone gap (ABG) (P > .05) and pure-tone average ABG (PTA-ABG) (P > .05). Meanwhile, the closure of PTA-ABG between the 2 groups showed no statistically significant differences in the overall distribution (P > .05). CONCLUSIONS:
