AI Article Synopsis
- The study aimed to assess how effective acellular dermal matrix allograft is for healing large oral mucosa defects.
- Forty-two cases with defects in various areas of the mouth were treated using this method, with patients monitored for 3 to 12 months post-surgery.
- The results showed high success rates, with 40 out of 42 wounds healing completely and no scarring, suggesting that this allograft may be a viable alternative to traditional skin grafts.
Article Abstract
Objective: To evaluate the clinical effect of acellular dermal matrix allograft in repairing the defect of oral mucosa.
Methods: Forty-two cases of large superficial defects in oral cavity were repaired by acellular dermal matrix. Defect areas included vestibule, tongue, the floor of mouth, buccal mucosa, palate, gingival and lip. Defect size was between 2.25 cm(2) and 12 cm(2). The basement membrane side of acellular dermal matrix was exposed to oral cavity, and another side was attached to the surgical wound surface. It was fixed by suture, reverse strapping and prepared template to overlaid large superficial defect of oral mucosa. The patients were followed up from 3 months to 1 year after operation.
Results: The wounds were completely healed in 40 cases, partially healed in 2 cases. There was no failure case. The healing was divided into two types: epithelialization healing pattern in 12 cases, attached healing pattern in 30 cases. Contraction of grafts occurred at 2 - 4 weeks. The contraction rate was 3.7% +/- 1.1% at fourth week. Scarring did not appear.
Conclusion: The clinical result of acellular dermal matrix allograft in repair the defect of oral mucosa is good. Acellular dermal matrix can be taken as a substitute to autograft of skin.
