目的 了解面神经和腮腺主导管之间解剖关系， 以利腮腺区的手术。方法 在行保留面神经腮腺浅叶及肿瘤切除术时， 解剖面神经和腮腺主导管， 观察其相互关系。结果 在３８ 例中， 腮腺主导管位于面神经深面或同一平面者２５ 例（６５ ．８ ％ ） ， 位于浅面者１３ 例（３４ ．２ ％ ） 。结论 在手术中对位于面神经深面的腮腺主导管予以保留， 没有切断或结扎，术后观察有以下优点：１ ． 保留腮腺的部分功能。２ ． 避免了因腮腺浅叶被切除及深叶腺体萎缩对面部外形的影响。３ ． 简化了手术步骤， 节省了手术时间。
Objective To understand the anatomic relationship between the facial nerve and the parotid main duct to facilitate the operation of the parotid gland. Methods In the preservation of facial parotid gland lobes and tumor resection, the facial nerve and the parotid main duct were dissected and their relationship was observed. Results In 38 cases, the parotid main duct was located in 25 cases (65.8%) of deep or same plane of facial nerve and 13 cases (34.2%) in superficial area. Conclusions During the operation, the parotid main duct, which is located deep in the facial nerve, is reserved without cutting or ligation. The following advantages are observed after operation: 1. Retain some of the parotid function. 2. Avoid the parotid shunt because of the shallow leaves and deep gland atrophy on the shape of the face. 3. Simplify the surgical procedures and save the operation time.
