OBJECTIVE
The aim of this study was to identify the distribution of parotid tumours within the gland in relation to the facial nerve branches. Documentation revealing such a relationship has not been reported previously.
METHOD
A prospective study involving 111 patients was carried out over a period of 18 years in a specialist otolaryngology unit within a district general hospital. The relationship of the facial nerve to the tumour was graded into six types. The grading system was then employed to categorize each case.
RESULTS
More than two-thirds of the tumours were pleomorphic adenomas. The majority of these were located in the body and not in the tail of the parotid gland. In 50 per cent of these cases, the tumour was in close association with the two major divisions of the facial nerve. In the case of Warthin's tumours, 47 per cent were located in the tail, below the lower division of the facial nerve.
目的
本研究旨在确定腮腺肿瘤在腺体内相对于面神经分支的分布情况。此前尚未有揭示这种关系的文献报道。
方法
在一家地区综合医院的专科耳鼻喉科单位，对111例患者进行了为期18年的前瞻性研究。面神经与肿瘤的关系分为六种类型。然后使用该分级系统对每个病例进行分类。
结果
超过三分之二的肿瘤为多形性腺瘤。其中大多数位于腮腺体部而非尾部。在这些病例中，50%的肿瘤与面神经的两个主要分支密切相关。在沃辛瘤的病例中，47%位于尾部，在面神经下部分支以下。
