Fresh Frozen Amniotic Membrane and Buccal Pad of Fat for Reconstruction of Oral Mucosal Defect After Surgical Excision of Leukoplakia
Abstract Objective: To compare the use of Fresh Frozen Amniotic Membrane (FFAM) and Buccal Pad of Fat (BPF) for reconstruction of oral mucosal defect after surgical excision of leukoplakia. Material and Methods: Twenty patients were randomly selected and divided into two groups. Group 1 use amniotic membrane graft and Group 2 BPF. Both groups were evaluated preoperatively and postoperatively. Incisal opening, epithelialization and fibrosis were evaluated after one month of surgery. Chi square and Student t tests were used. Results: According to the presence of smoking habits, the highest frequencies were for smoking (30%) and betel leaf areca nut with tobacco (30%). Regarding the diameter of oral leukoplakia, in 40% of the participants it was 2x3 cm2. In Group1, after one month of surgery preoperative and postoperative inter-incisal opening values were 44.20 ± 3.37 and 42.05 ± 3.47 (p<0.001). In Group 2, preoperative and postoperative inter-incisal opening values were 44.09 ± 3.32 and 43.01±3.38 (p>0.05). When FFAM was used complete epithelialization in 70% and incomplete epithelialization in 30% patients. When BPF was used the results were almost similar. Fibrosis occurred in 30% in Group 1. There were no complications like flap necrosis, infectiona and hematoma formation. Conclusion: Incisal opening was significantly better in Fresh Frozen Amniotic Membrane Group, epithelialization and fibrosis were almost same in both groups after surgical excision of oral leukoplakia.
