Use of allograft dermal matrix for repairing large oral epithelial defects: Outcomes of patients with lingual and buccal leukoplakia
2021
BACKGROUND The best treatment approach for wide oral leukoplakia (OL) remains to be determined. AIMS To evaluate the outcomes of using an allograft dermal matrix (ADM) for reconstructing large oral epithelial defects following resection of OLs. PATIENTS AND METHODS A total of 27 OLs in 26 patients were excised, and residual large lingual and buccal epithelial defects were reconstructed using an ADM, which ranged in size from 3.0 × 5.0 to 6.0 × 6.0 cm. The patients were classified into mild (n = 1), moderate (n = 13), and severe dysplasia (n = 12) groups; 57.7% of the patients were tobacco smokers, 46.2% were alcoholics, 47.2% were both smokers and alcoholics, and 11.5% were both smoking and betel quid chewers. Patients who underwent surgery were advised to quit smoking, drink alcohol in moderation, or quit betel quid chewing. RESULTS Two patients developed slight hematomas that resolved spontaneously within 2 weeks. A total of 76.9% of the smokers followed the advice to quit smoking, 83.3% of the alcoholics followed the advice to drink in moderation, and all three betel quid chewers followed the advice to quit chewing betel quid. The mean follow-up was 26.7 months. No MT occurred and recurrence was seen in two patients. CONCLUSIONS Large epithelial defect reconstruction using an ADM following resection of wide lingual and buccal OLs was safe and reliable for preventing MT of OL. The recurrence of OL may be related to patient habits such as tobacco smoking or/and drinking alcohol.
