Clinical efficacy and safety analysis of xenogeneic acellular dermal matrix in repairing ear skin defects: a single-center prospective study

Xeno-ADM demonstrates excellent efficacy and safety for ear skin defect repair, offering rapid epithelialization, significant hearing improvement, minimal pain, and high patient satisfaction during the mean follow-up of 6 months. However, the absence of a control group limits the strength of these conclusions, and long-term outcomes remain unknown due to the limited follow-up duration.
