Purpose:
Artificial grafts have been investigated for use in the repair of oral mucosal defects. The aim of this retrospective study was to present the outcomes of the use of acellular dermal matrix (ADM) grafts to repair oral mucosal defects.
Materials And Methods:
Data from 36 patients with oral mucosal defects reconstructed with ADM grafts from 2003 through 2009 were reviewed. All patients were followed-up for at least 6 months to observe the graft repair, wound-healing time, contracture, color, infection, pain, immunologic reaction, texture of the graft, and clinical course. Graft success was defined as the ADM graft being replaced by new mucosa-like tissue and the oral mucosal defect being covered with the new mucosa-like tissue. Any evidence of incomplete graft re-epithelialization or graft sloughing was considered a graft failure (complete or incomplete).
Results:
Of the 36 cases, 34 grafts (94.4%) were successfully replaced with new mucosa-like tissues and only 2 grafts (5.6%) failed. No complaints such as pain, immunologic reaction, or infection were observed during the follow-up. Mild graft contraction occurred in 7 patients with lip or buccal defects, especially at approximately 3 to 5 weeks after the reconstructive surgery.
Conclusions:
The ADM grafts for oral mucosal defects were safe and effective. The present data support the clinical application of ADM grafts in reconstructing oral mucosal defects caused by various oral diseases.
