下颌下腺自发性分泌唾液量约占唾液总量的70%~90%。手术切除后唾液总量下降,常常导致口干症,从而使患者的生活质量下降。该文旨在评估转移淋巴结与下颌下腺的关系,并探讨口腔恶性肿瘤出现颈淋巴结转移后,保留下颌下腺的手术是否可行。将患侧下颌下腺周围的纤维脂肪组织标本分为6个部分进行病理检测。结果:137例接受颈淋巴清扫的口腔癌患者中,85例为cN0,52例为cN+。Ib区cN0组患者转移率为8.2%,cN+组患者转移率为40%。cN0组仅1例患者出现下颌下腺深部转移,占
Submandibular salivary spontaneous secretion of saliva volume accounts for about 70% to 90%. The drop in total saliva volume after surgical resection often leads to dry mouth, leading to a decline in the patient’s quality of life. This article aims to assess the relationship between metastatic lymph nodes and submandibular glands and to investigate the feasibility of preserving the submandibular gland after cervical lymph node metastases in oral malignancies. The ipsilateral submandibular gland around the fibrous adipose tissue specimens were divided into six sections for pathological examination. Results: Among 137 oral cancer patients undergoing neck dissection, 85 were cN0 and 52 were cN +. Ib District cN0 patients with metastasis rate was 8.2%, cN + patients with metastasis rate was 40%. Only 1 patient in cN0 group showed deep submandibular gland metastasis, accounting for
