| Introduction: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstrate the hearing outcome after a modification of the incus interposition technique, which involved preserving it in the periauricular soft tissue. Materials and Methods: In the primary operations, tympanoplasty was performed with a postauricular incision. At the end of the surgery, a small pocket was created to preserve the incus beneath the temporalis fascia. The second stage of ossiculoplasty was performed 6 to 18 months after the primary operation. Post-operative pure tone audiometry was analyzed after at least 12 months and was considered successful after achieving an air-bone gap (ABG) within 20 dB. Results: In this paper, we analyzed 199 ears. The mean duration of follow up was 2.5 years. We achieved post-operative ABG within 20 dB in 157 patients (78.9% of patients). Conclusion: This study indicates the efficacy and safety of incus interposition when it is preserved in the postauricular soft tissue. | ||
