颌下腺导管口狭窄或腮腺导管穿过颊肌处过度弯曲,涎液排出障碍,是发生慢性涎腺炎的因素之一。为治疗这类涎腺炎,作者施行颌下腺导管口成形术21例,16例有效,临床症状缓解2～6年。手术方法:局部浸润麻醉,围绕导管口切开粘膜并顺导管方向向后延长1.0～1.5cm(图中A切口),分离出导管前部2～2.5cm。从A切口向后1cm处呈十字形(各长0.6～0.7cm)切开粘膜(B切口),钝性分离,使游离的导管前部从B切口引出,剖开导管壁使呈4个花瓣形,用无创针缝合在B切口的创缘。缝合A切口。见图:
Submandibular gland duct stenosis or parotid duct parotid duct over-bending, salivation discharge disorders, is one of the factors in the occurrence of chronic sialadenitis. For the treatment of such sialadenitis, the authors performed submandibular gland portoplasty in 21 cases, 16 cases of effective, clinical symptoms ease 2 to 6 years. Surgical methods: local infiltration anesthesia, incision mucosa around the catheter port and the direction of the catheter to extend backward 1.0 ~ 1.5cm (A incision in the figure), separated the front of the catheter 2 ~ 2.5cm. A mucosal incision (B incision) was made at 1 cm posterior to A incision (each 0.6-0.7 cm in length), blunt dissected, and the free catheter anterior part was taken out from B incision. The catheter wall was cut to make 4 petals Shape, with a non-invasive needle suture wound in the B margin. Suture A incision. See figure:
