CONCLUSIONS: The procedure maximally retains the physiological structure of the middle ear and external auditory canal, thus effectively improving the patient's hearing ability.
OBJECTIVE: We explored the clinical outcomes of treating chronic suppurative otitis media using improved intact canal wall radical mastoidectomy with sandwich graft tympanoplasty.
METHODS: We chose to perform intact canal wall radical mastoidectomy with sandwich graft tympanoplasty in patients with chronic suppurative otitis media. A total of 170 patients were included in the study. Statistical analysis was carried out using software SPSS18.0, adjusted with the chi-squared test.
RESULTS: In all, 140 cases were shown to have been treated effectively (82.35%, 140/170). The increased auditory threshold of preoperative bone conduction was not related to the duration of disease and/or the presence of cholesteatoma (p > 0.05), but was associated with ossicular chain disruption or fixation (p < 0.05), specifically the ossicular chain destruction/absorption, granulation tissue wrapping, and consequent fixation. During the procedure, the sleeve-like pedicle flap of external auditory canal and tympanic membrane is covered with graft, allowing good fixation with maintenance of the tympanic membrane's natural shape. The auditory threshold test revealed equal or above normal levels (30 dB) for 126 cases (74.12%, 126/170). The primary healing rate of tympanic membrane achieved was 96.47% (164/170).
