The purpose of the present case report was to document a maxillary sinus floor augmentation procedure involving ligation of a blood vessel with a nearly 3-mm diameter in the lateral wall of the maxillary sinus.
A bilateral maxillary sinus floor augmentation procedure was performed in a 51-year-old healthy man. The preoperative computed tomography scan revealed a bony canal within the lateral maxillary sinus wall of the right as well as the left side close to the alveolar ridge.
A vessel with a diameter of nearly 3 mm was identified during the sinus floor augmentation on the left side. The vessel was exposed and ligated. A vessel with a diameter of approximately 1 mm was identified on the right side and the sinus floor augmentation was performed without ligation. No complications were observed and the postoperative healing was uneventful.
Although accidental laceration of vessels with an unusually large diameter during maxillary sinus floor augmentation is not life-threatening, impaired visualisation may compromise the augmentation procedure, including the elevation of the Schneiderian membrane. Moreover, postoperative bleeding and formation of a haematoma may occur. Therefore, ligation of vessels with an unusually large diameter is recommended during maxillary sinus floor augmentation to minimise intra- and postoperative complications.
本病例报告的目的是记录上颌窦底提升手术，该手术涉及结扎上颌窦外侧壁一条直径近3毫米的血管。
对一名51岁健康男性进行双侧上颌窦底提升手术。术前计算机断层扫描显示右侧以及左侧上颌窦外侧壁靠近牙槽嵴处有骨管。
在左侧上颌窦底提升手术过程中发现一条直径近3毫米的血管。该血管被暴露并结扎。右侧发现一条直径约1毫米的血管，未结扎就进行了上颌窦底提升手术。未观察到并发症，术后愈合顺利。
虽然在上颌窦底提升手术中意外撕裂直径异常大的血管不会危及生命，但视野受损可能会影响手术，包括施奈德膜的提升。此外，术后可能会出血并形成血肿。因此，建议在上颌窦底提升手术中结扎直径异常大的血管，以尽量减少术中及术后并发症。
