| Abstrakt: | Objective: To describe the use of acellular dermal matrix (ADM) in the repair of acquired external auditory canal atresia (AEACA), and compare surgical results to AEACA repair by split-thickness skin grafting (STSG). Study Design: Retrospective chart review. Setting: Neurotology clinical practice. Patients and Intervention: From 2007 to 2015, 25 AEACA surgeries (8 ADM and 17 STSG) were identified meeting inclusion and exclusion criteria. Pre- and postoperative audiometric data with clinical follow-up were examined. Outcome Measures: Rate of external auditory canal restenosis, improvement of conductive hearing loss, and resolution of otorrhea. Results: Both surgical groups had similar preoperative air bone gaps (ABG). Mean follow-up was 24 months. There was no significant difference in restenosis rates between the ADM (13%, n = 1/8) and STSG (12%, n = 2/17) groups. ABG improved from 28 dB to 11 dB in the ADM group and from 24 dB to 9 dB in the STSG group. ABG closure with surgery was statistically significant (p < 0.05), but there was no difference between the two groups. There was no significant reduction of otorrhea. Conclusion: Acellular dermal matrix grafting has not been previously reported for use in AEACA repair, and is a reasonable alternative to STSG with similar hearing, restenosis, and otorrhea outcomes. |
