An oroantral fistula is a communication between the maxillary antrum and oral cavity. This pathological communication is formed mainly due to dental extraction of maxillary premolars and molars. Adequate management should include closing the oroantral fistula and eliminating sinus infections to prevent recurrence and sinusitis.
This study aimed to evaluate the effectiveness of using the pedicled buccal periosteal flap for closing an oroantral fistula without changing the native intraoral structure.
PATIENTS & METHODS: Patients with oroantral fistulas were included in this study. The patients were examined clinically by Valsalva test and cheek-blowing test, the hole was probed, and the extent of the underlying bone defect was determined radiographically using computed tomography preoperatively. All patients underwent surgical closure of oroantral fistula using a pedicled buccal periosteal flap.
All 10 patients obtained satisfactory results with marked improvement in the function of the maxillary sinus and complete healing of oroantral fistula with no recurrence except in Case No. 5, who had a recurrence of the oroantral fistula, also there was no statistically significant difference between the vestibular depth preoperatively and postoperatively.
A pedicled buccal periosteal flap is a novel technique for oroantral fistula closure as it preserves vestibular depth with a tension-free closure flap and harbors the advantages of the regenerative potential of the periosteum.

牙槽窦瘘是上颌窦与口腔之间的连通。这种病理性连通主要是由于上颌前磨牙和磨牙的拔牙引起的。适当的治疗应包括关闭牙槽窦瘘并消除窦感染，以防止复发和鼻窦炎。
本研究旨在评估使用带蒂颊侧骨膜瓣关闭牙槽窦瘘而不改变固有口内结构的有效性。
本研究纳入了牙槽窦瘘患者。患者通过瓦尔萨尔瓦（Valsalva）试验和颊吹气试验进行临床检查，探查瘘孔，并在术前使用计算机断层扫描（CT）确定骨缺损的程度。所有患者均采用带蒂颊侧骨膜瓣行牙槽窦瘘闭合手术。
除 5 号病例外，所有 10 例患者均获得满意效果，上颌窦功能明显改善，牙槽窦瘘完全愈合，无复发。5 号病例出现牙槽窦瘘复发，但术后前庭深度与术前相比无统计学差异。
带蒂颊侧骨膜瓣是一种用于关闭牙槽窦瘘的新方法，它可以保持前庭深度，并且瓣的关闭无张力，具有骨膜的再生潜力优势。
