Abstract

OBJECTIVES: To evaluate the effects of size of temporal fascia graft on healing of the mastoid cavity in patients undergoing canal wall down (CWD) procedures.

MATERIALS AND METHODS: The study included 32 patients (ages from 10 to 69 years) who were performed CWD tympanomastoidectomy from 2016 to 2018. Patients were divided into 2 different groups randomly based on size of fascia used in the operations. Group 1 consisted of 19 patients with temporal muscle fascia large enough to extend up to antrum by passing through over the facial ridge. Group 2 consisted of 13 patients with fascia of a size hardly enough to create a middle ear space, which were quite smaller than those the first group. It was also observed that whether or not the type of pathology (cholesteatoma, granulation tissue or both) had an effect to the epithelialization time of the cavity.

RESULTS: Thirty-two patients met inclusion criteria. Nineteen patients were randomized to study (large fascia) group and 13 patients were to control (small fascia) group. The mean duration for epithelialization of cavities with study group-large grafts was 34.10 days and that was 39.76 days in control group-small grafts. According to type of pathology; in cases with cholesteatoma, with granulation, and cases of coexisting granulation with cholestatoma; the mean epithelialization times were 38.73, 31.33 and 34.42 days, with respectively.

CONCLUSION: Placement of larger fascia graft to line the mastoidectomy cavity facilitate rapid epithelialization and healing in patients undergoing CWD tympanomastoidectomy. Further studies with larger groups would be beneficial to confirm this result in the aspect of statistical significance.
