目的 探讨颌下腺切除的新术式,比较以往单纯从口外颌下皮肤切口的术式。方法 于经鼻全麻下,切口采用口内入路长约3cm,自第一双尖牙近中至第二磨牙远中舌侧利用窥镜口底入路,分别切断与颌下腺有关的神经、动脉、静脉及导管,完整摘除颌下腺。结果 4例患者均顺利切除颌下腺,术后无并发症。结论 内窥镜切除颌下腺在临床上是可行的,颌面部皮肤无手术切口,利于美观,同时此术式有效避免了面神经下颌缘支的损伤。
Objective To investigate the new surgical technique of submandibular gland resection and to compare the simple procedure of simple submandibular skin incision. Methods Under nasal anesthesia, the incision was made with an intraoral approach of about 3 cm in length. From the first bicuspid to the distal mid-lingual side of the second molar, the submandibular gland-related nerves and arteries , Veins and catheters, complete removal of the submandibular gland. Results All patients underwent submandibular gland resection without complications. Conclusion Endoscopic resection of the submandibular gland is feasible in clinical practice. There is no operative incision in maxillofacial region, which is good for aesthetics. At the same time, this technique can effectively avoid the injury of the marginal mandibular branch of facial nerve.
