目的

探讨口内入路颌下腺切除术可行性及手术安全性。

方法

对70 例颌下腺与颌外动脉的关系进行重新解剖及文献复习，为口内入路的颌下腺切除术提供解剖学基础。行口内入路的颌下腺切除术15 例，含内窥镜辅助下口内入路2 例。

结果

67.1%（47／70）颌外动脉是走行于颌下腺腺体表面，分出2～4 支滋养支供血腺体。 15 例口内入路的颌下腺切除术过程顺利，4例颌外动脉需术中结扎，未出现术中、术后大出血等并发症。 内窥镜有利于口底区血管的结扎和止血。

结论

只要严格掌握适应症，妥善处理颌外动脉，口内入路的颌下腺切除术是安全可靠，内窥镜可增加术野的清晰度。

Objective

To investigate the feasibility and safety of intraoral submandibular gland excision.

Methods

Analyze the relationship between external maxillary artery and submandibular gland by dissecting 70 cases and reviewing the literatures so as to offer a reliable anatomical base for the 15 cases of intraoral submandibular gland excision including 2 cases with the aid of endoscope.

Results

67.1%（47／70） of the external maxillary artery freaded on the surface of submandibular gland， providing nutrition for the gland through 2～4 branches. The processes of 15 cases of intraoral submandibular gland excision were smooth， and the results of all the cases were effective and satisfying， without massive hemorrhage during or post-operation. External maxillary artery needed to be ligated only in 4 cases of intraoperation. Endoscope and ultrasound knife facilitate the ligation and hemostasis of vascular vessels.

Conclusion

Intraoral submandibular gland excision is safe and feasible as long as indications are strictly controlled and the external maxillary artery is well coped with.Endoscope improves the operating vision in deep region.
