脱细胞真皮基质复合小牛脱细胞骨修复口腔上颌窦瘘

目的 评价脱细胞真皮基质复合小牛脱细胞骨修复口腔上颌窦瘘的效果。方法 选择上颌骨囊肿摘除术或上颌磨牙拔除术后口腔与上颌窦相通的9例口腔上颌窦瘘患者（缺损大于5 mm×5 mm）,采用脱细胞真皮基质复合小牛脱细胞骨进行同期植入修复缺损。结果 9例患者术后切口均一期愈合,随访6个月,口腔上颌窦相通处黏膜均未见瘘道及分泌物,无鼻塞、流脓涕等上颌窦炎症相关症状,临床检查鼓气试验及CT检查均证实创口愈合。结论 应用脱细胞真皮基质及小牛脱细胞骨修复口腔上颌窦瘘,是一种有效的治疗方法。

Clinical analysis of acellular dermal matrix and acellular bone matrix in oro-antral fistula repair

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.
