BACKGROUND
To investigate the distribution of the parotid gland's intraglandular lymph nodes using the parotidectomy zones determined by the parotidectomy classification of the European Salivary Gland Society (ESGS).
MATERIALS AND METHODS
A total of 128 parotid glands were dissected from 64 fresh cadavers, by bilateral parotidectomy without additional incision within the standard autopsy procedure, and categorized.
RESULTS
Eighty-six percent of the IGLNs were located in the superficial lobe and 14% in the deep lobe. An average of 7.09 ± 3.55 IGLNs were found for each of the gland; there were 6.11 ± 3.28 in the superficial lobe and 0.98 ± 1.46 in the deep lobe. While the most common lymph nodes were found in level 2 with 47.7%, only 5% of IGLNs were at level 4. According to the proposed modification, the most common lymph nodes (35.24%) were located at level 2B.
CONCLUSION
Level 2B was found to contain significantly more lymph nodes than other levels, which has not been evaluated before in literature.
背景
利用欧洲涎腺学会（ESGS）腮腺切除术分类所确定的腮腺切除区域，研究腮腺腺体内淋巴结的分布情况。
材料与方法
在标准尸检程序内，通过双侧腮腺切除术且无额外切口，从64具新鲜尸体上共解剖出128个腮腺，并进行分类。
结果
86%的腺体内淋巴结位于浅叶，14%位于深叶。每个腺体平均发现7.09±3.55个腺体内淋巴结；浅叶有6.11±3.28个，深叶有0.98±1.46个。虽然最常见的淋巴结位于2级，占47.7%，但只有5%的腺体内淋巴结位于4级。根据提议的修改，最常见的淋巴结（35.24%）位于2B级。
结论
发现2B级所含淋巴结明显多于其他级别，这在之前的文献中尚未得到评估。
