    Abstract:
    CONCLUSIONS: The procedure cleared the lesion completely and preserved the physiological function of the external auditory canal. OBJECTIVE: To develop a novel surgical procedure to treat chronic suppurative otitis media (CSOM). To explore the merit of using pedicled temporalis myofascia (PTM) and reconstruction of the posterior wall of the external auditory canal with pedicled postauricular periosteal flap and intact skin of the external auditory canal. METHODS: Forty-seven patients with CSOM were chosen. Open radical mastoidectomy was used to complete clean-up lesions; the fascia of PTM was used to repair the tympanic membrane. The PTM, pedicled postauricular periosteal flap, and intact skin of the external auditory canal were used in the reconstruction of the posterior wall of the external auditory canal. All subjects were followed up for over 2 years. Hearing thresholds, including air conduction (AC), bone conduction (BC), and air-bone gap (ABG) before and after surgery, and after follow-up, were compared. RESULTS: The healing rate of postoperated tympanic membrane was 95.74% and the 2-year healing rate of tympanic membrane perforation was 95.65%. The 46 ears included in the 2-year follow-up showed significant improvement between preoperative and postoperative AC and ABG values.
