Repair effect of xenogeneic acellular dermal matrix during external auditory canal reconstruction after canal wall down mastoidectomy.
Background: In some cases, there is insufficient external auditory canal (EAC) skin to cover the reconstructed canal wall after canal wall down (CWD) mastoidectomy. Acellular dermal matrix (ADM) can help to repair the skin, mucosa and other epidermal tissue defects. Aims: To investigate the repair effect of xenogeneic ADM (xeno-ADM) for EAC skin defects. ⋯ The postoperative epithelialization time was 5.8 ± 1.6 weeks, and the number of dressing changes was 4.8 ± 1.6 times. There was no xeno-ADM rejection and related complications, the postoperative hearing improvement was statistically significant (p = .013). Conclusions and Significance: Xeno-ADM could be a safe, effective and simple method for repairing skin defect in the reconstruction of EAC after CWD mastoidectomy.
