“…Ananian et al (2015), in an anatomic-histologic study, identi ed LLNs in 23.8% cadavers and found a relatively high incidence of mucous-associated lymphoid tissue (MALT) in the tongue and oor of the mouth mucosa [34]. Suzuki et al (2016) classi ed LLNs into the following subgroups: median, anterior lateral (in the proximity of the sublingual gland), para-hyoid and posterior lateral (outside the lateral sublingual space -at the inner surface of the submandibular gland). This group was mostly avoided by previous authors [35].…”

Purpose:Metastatic involvement of the lingual lymph nodes (LLNs) in oral cavity squamous cell cancer has recently been proven to signi cantly reduce locoregional control and survival. Despite recent re nements in the detection of these lesions, the understanding of the LLN topographic anatomy among clinicians is limited. A proposition of a topographic division on LLN based on a comprehensive literature search and synthesis may be helpful in this condition.Methods:A literature search and election based on contemporary PRISMA guidelines was performed for sources on LLN anatomy with special attention on their subdivision.Results:Four topographic LLN subgroups were de ned: median -between genioglossal and geniohyoid muscles; intermediate para-hyoid -medial to the hyoglossal muscle, at the greater cornu of the hyoid bone; lateral sublingual (paraglandular) LLNs -at the sublingual salivary gland; lateral submandibular (paraglandular) LLNs -lateral to the hyoglossal muscle, at the deep surface of the submandibular salivary gland. Conclusion:The development and implementation of a uni ed anatomical topographic classi cation of LLN subgroups may be among the important conditions for improving the detection and treatment of LLN lesions.

В классических источниках данные о латеральных ЯЛУ представляют собой описания непостоянных по своему количеству и расположению маленького размера ЛУ, лежащих по ходу лимфатических сосудов языка до вступления последних в регионарные ЛУ глубокой шейной цепи и подчелюстного и подподбородочного треугольников [32][33][34].…”

A review of accumulated international clinical experience and prognostic significance calculations of metastatic involvement of the lingual lymph nodes is given. Anatomical terminology of lingual lymph nodes and its contradictive aspects are discussed. It is shown that metastatic lesions of the lingual lymph nodes posses high prognostic value, therein a topographic anatomic classification of the lingual lymph nodes is needed to increase the efficiency of diagnosis and augmenting of the oncologic treatment results. This classification should be unified to avoid misunderstanding between researchers.

“…Median LLNs were spotted as rare as 0.95% in a large imaging series[ 13 ]. Surgical-anatomical classification of LLNs was proposed by Suzuki et al[ 14 ], where LLNs were distributed into four subgroups: Median LLNs, anterolateral LLNs (located in proximity to the sublingual gland), parahyoid LLNs (located along the greater cornu of the hyoid bone), and posterolateral LLNs. This group consists of one or two small lymph nodes outside the sublingual and floor of the mouth regions.…”

“…Hoshina et al[ 16 ] observed lateral LLN metastasis in 16.3% of 43 patients with tongue SCC. Suzuki et al[ 14 ] reported an 8% incidence of LLN metastasis in a series of 100 tongue SCCs, and proposed recommendations for choosing surgical access to different LLN groups. The anterolateral paraglandular nodes are accessed intraorally, the posterolateral parahyoid node resection requires additional dissection of the tissue at the greater cornu of the hyoid close to the parapharyngeal space, and the deep submandibular node should be removed during neck dissection together with the submandibular salivary gland.…”

Lingual lymph nodes are an inconstant group of in-transit nodes, which are located on the route of lymph drainage from the tongue mucosa to the regional nodes in neck levels I and II. There is growing academic data on the metastatic spread of oral cancer, particularly regarding the spreading of oral tongue squamous cell carcinoma to lingual nodes. These nodes are not currently included in diagnostic and treatment protocols for oral tongue cancer. Combined information on surgical anatomy, clinical observations, means of detection, and prognostic value is presented. Anatomically obtained incidence of lingual nodes ranges from 8.6% to 30.2%. Incidence of lingual lymph node metastasis ranges from 1.3% to 17.1%. It is clear that lymph nodes that bear intervening tissues from the floor of the mouth should be removed to improve loco-regional control. Extended resection volume, which is required for the surgical treatment of lingual node metastasis, cannot be implied to every tongue cancer patient. As these lesions significantly influence prognosis, special efforts of their detection must be made. Reasonably, every tongue cancer patient must be investigated for the existence of lingual lymph node metastasis. Lymphographic tracing methods, which are currently implied for sentinel lymph node biopsies, may improve the detection of lingual lymph nodes.
