“…1,2,14 In addition, in recent years there has been increase in trends of putting dental implants in mandibular posterior region which has also led to damage of lingual nerve causing paresthesia of tongue 9,15,16 and altered sensation. 17,18 Various authors had described the spatial variation of lingual nerve 5,7,8,[19][20][21] and abnormal communication of lingual nerve with auriculotemporal nerve 11,12 and inferior alveolar nerve. 22,23 Variations also exist on the level of trifurcation of lingual nerve, inferior alveolar nerve and auriculotemporal nerve.…”

“…In another study performed on University of Alabama in 28 hemisected cadaveric skulls, the vertical measurement was 7 mm. 20 This study measured the vertical distance at the second molar region while the measurement of this study was taken at the third molar region. The difference in the measurement can also be explained by the fact that the third molar crest lies lateral to the second molar and is at the higher level.…”

Background: The lingual nerve is the terminal branch of the mandibular division of trigeminal nerve. The spatial relationship of lingual nerve to the mandibular alveolar crest varies widely. This variation can be among the gender, age, dental status and between the right and left side of the same sample. This study was aimed to determine the relationship of lingual nerve to mandibular third molar region. Methods: An observational study was carried out from January 2021 to December 2021.The study sample was 15 cadavers including both right and left sides. The lingual nerve was exposed by dissecting the infra temporal region following the standard procedures of Cunninghams Manual of Dissection. The diameter of the lingual nerve, vertical and horizontal distance were measured. The results of all these measurements were tabulated and mean standard deviation were calculated using SPSS version 16. Results: Out of 30 lingual nerves examined, the mean horizontal distance was 3.99 ± 0.96 mm, the mean vertical distance was 12.67 ± 1.76 mm while the diameter of the lingual nerve was 2.46 ± 0.54 mm. Conclusions: The lingual nerve always lies in close proximity of alveolar bone and surgeons operating in this region need to be aware during any surgical interventions or any procedures in this region. A thorough apprehension of the spatial location of the lingual nerve enable to lessen the lingual nerve injury.

“…At Carnegie stages 20 to 21 (weeks 7–7.5 of development), the submandibular duct is formed by a bistratified cuboidal epithelium and is located cranial to the lingual nerve and the parasympathetic ganglion 9 . Commonly, the lingual nerve crosses the submandibular duct at the interproximal space in the mandibular molar region 2,10 . To our knowledge, there were only 4 studies that investigated the anatomical relationship between the lingual nerve and submandibular duct (Supplementary Digital Content, Table 1, http://links.lww.com/SCS/D256).…”

The purpose of this study was to investigate the anatomical relationship between the lingual nerve and submandibular duct. This study included 1403 patients with submandibular or sublingual gland diseases who underwent intraoral removal of submandibular gland sialoliths, submandibular glands, or sublingual glands. Of all patients, 33 patients underwent bilateral surgeries. All surgeries were performed a single surgeon, and the anatomical relationship between the lingual nerve and submandibular duct was always identified intraoperatively and recorded in the operation recorded. The anatomical relationship was investigated based on the intraoperative findings. The lingual nerve which crosses above the submandibular duct was detected in 8 of 1436 sides (0.6%). There were 4 in the right sides and 4 in the left sides. The lingual nerve below the submandibular gland was seen in 99.4%. Although the lingual nerve crosses above the submandibular duct with a rarer incidence, surgeons should beware of injuring the lingual nerve during intraoral salivary gland surgery.

“…Out of 152 initially evaluated, 131 were excluded due to (1) being case reports or case series ( n = 21); (2) having no data, which was relevant to the study topic ( n = 67); (3) having no numerical data ( n = 43). Finally, a total of 21 studies were included in this meta‐analysis (Al‐Amery et al, 2016; Behnia et al, 2000; Benninger et al, 2013; Chan et al, 2010; Dias et al, 2015; Erdogmus et al, 2008; Hölzle & Wolff, 2001; Iwanaga, 2017; Karakas et al, 2007; Kiesselbach & Chamberlain, 1984; Kikuta et al, 2019; Kim et al, 2004; Kocabiyik et al, 2009; Mendes et al, 2013; Miloro et al, 1997; Pogrel et al, 1995; Shimoo et al, 2017; Shinohara et al, 2010; Sittitavornwong et al, 2017; Tan et al, 2014; Trost et al, 2009).

Lingual nerve (LN) injury during surgical procedures in the third molar region warrants a detailed study of its common pathway and important variations. Therefore, the objective of this study was to analyze and compile the multiple anatomical variations of the LN for use in oral and maxillofacial surgery. It is anticipated that the results of the present meta-analysis may help to minimize the possible complications when performing procedures associated with this anatomical entity. Major online databases such as PubMed, Web of Science, Scopus, Embase were used to gather all relevant studies regarding the LN anatomy. The results were established based on a total of 1665 LNs. The pooled prevalence of the LN being located below the lingual/ alveolar crest was found to be 77.87% (95% CI: 0.00%-100.00%). The LN was located above the lingual/ alveolar crest in 8.21% (95% CI: 4.63%-12.89%) of examined nerves. The most common shape of the LN was established to be round with a prevalence of 40.96% (95% CI: 23.96%-59.06%), followed by oval at 37.98% (95% CI: 23.98%-53.02%) and flat at 25.16% (95% CI: 12.85%-39.77%). In conclusion, we believe that this is the most accurate and up-to-date study regarding the anatomy of the LN. The LN was found to be located below the lingual/alveolar crest in 77.87% of the cases. Furthermore, the LN was found to enter the tongue under the submandibular duct in 68.39% of the cases. Knowledge about the anatomy of the LN is crucial for numerous oral and maxillofacial procedures such as during the extraction of the third molar.

Abstract: Given the multiple procedures by dental practitioners and maxillofacial surgeons, the LN is at high risk for injury. This study validates the proximity of the LN to anatomic structures commonly encountered during head and neck procedures.
