Abstract:

Objective This study aimed to investigate the application of acellular dermal matrix and acellular bone matrix in the management of oro-antral fistula.Methods Nine patients with oro-antral fistula (with defect greater than 5 mm×5 mm) after maxillary cyst resection or maxillary molar extraction were selected. The defects were repaired by the simultaneous implantation of acellular dermal matrix and acellular bone matrix.Results The incisions of nine patients were all primary healing. After 6 months of follow-up, the oro-antral communication healed well, and no symptom such as nasal congestion or runny nose was observed. The clinical and CT examinations confirmed wound healing.Conclusion The usage of acellular dermal matrix and acellular bone matrix is a reliable repairing method for ora-antral fistula.

Key words: acellular dermal matrix, acellular bone matrix, oro-antral fistula, maxillary sinusitis
