Anatomic-histologic study of the floor of the mouth: the lingual lymph nodes

Abstract

The presence of lymph node-bearing tissue in the floor of the mouth is demonstrated. In account of resection radicalism and better local control the fat tissue of the floor of the mouth should be removed in conjunction to glossectomy. Further anatomic and clinical research is required to establish the role of lingual lymph node in oral squamous cell carcinoma recurrence and metastasis.

Lingual lymph nodes in patients with squamous cell carcinoma of the tongue and the floor of the mouth

“…In our series, we found the incidence of LLNs was 17.12% (19/111 patients). The lateral group was detected in 11 patients (9.91%) and the median group in 8 patients (7.21%), which was lower than a previous report . The possible explanations are ethnic differences and the fact that the previous research was based on autopsy.…”

“…The lateral group was detected in 11 patients (9.91%) and the median group in 8 patients (7.21%), which was lower than a previous report. 12 The possible explanations are ethnic differences and the fact that the previous research was based on autopsy. Also, because LLNs are very small and in close proximity to the primary lesion, it is difficult to find them during the surgical procedure.…”

Value of lingual lymph node metastasis in patients with squamous cell carcinoma of the tongue

“…Mashkov et al found LLNs within the tongue musculature in 8.6% of 104 cadavers investigated and grouped LLNs as regional draining lymph nodes of the oral tongue. Ananian et al reported that LLNs with an overall number of 7 were detected in five of the 21 cadavers (23.8%). The total incidence of lingual lymph nodes was 33.3% (7 nodes/21 cadavers).…”

“…There have been a few anatomic studies of LLNs . Katayama et al reported that the incidences of medial and lateral LLNs were 15.1% and 30.2%, respectively.…”

A Review of Techniques for Sentinel Lymph Node Mapping with Special Reference to the Head and Neck Region

“…46 Possibly this matter may be at least in part accounted for often overlooked lingual lymph nodes which in a recent anatomical study were reported to be present in 23.8% of individuals and can serve as SLNs for some tongue and mouth floor cancers. 47 Apart from this radioisotope technique craves radiation exposure to both patients and the medical staff and requires special protection and waste disposal policy. 48 While conventional CT and MRI have limited ability for neck metastasis detection and are used mainly for the primary site lesion extension assessment and staging 49 some researchers investigated their usefulness in SLN detection.…”
