“…The relationship of the LN with other structures such as the submandibular duct, the hypoglossal nerve, the inferior alveolar nerve, or the region of mandibular third molar have been described [ 21 , 27 , 28 ]. However, we have not been able to find in the literature studies with similar measurements.…”

Purpose To describe the anatomic relationship of the lingual nerve with the lateral oropharyngeal structures. Methods An anatomic dissection of the lateral oropharyngeal wall was conducted in eight sides from four fresh-frozen cadaveric heads. Small titanium clips were placed along the lingual nerve and the most anterior and medial border of the medial pterygoid muscle. Radiological reconstructions were employed for optimal visualization; the coronal view was preferred to resemble the surgical position. The distance between the lingual nerve and the medial pterygoid muscle at its upper and lower portion was measured radiologically. The trajectory angle of the lingual nerve with respect to the pterygomandibular raphe was obtained from the intersection between the vector generated between the clips connecting the upper and lower portion of the medial pterygoid muscle with the vector generated from the lingual nerve clips. Results The mean distance from the upper portion of the medial pterygoid muscle and superior lingual nerve clips was 10.16 ± 2.18 mm (mean ± standard deviation), and the lower area of the medial pterygoid muscle to the lingual nerve was separated 5.05 ± 1.49 mm. The trajectory angle of the lingual nerve concerning to the vector that describes the upper portion of the most anterior and medial border of the medial pterygoid muscle with its lower part was 43.73º ± 11.29. Conclusions The lingual nerve runs lateral to the lateral oropharyngeal wall, from superiorly–inferiorly and laterally–medially, and it is closer to it at its lower third.

“…Many anatomical studies of the lingual nerve, especially in the mandibular third molar or ramus region, have been investigated to avoid nerve injury during the extraction or dental anesthesia by many researchers 1,4–7 . However, the anatomical relationship between the lingual nerve and submandibular duct has not been investigated sufficiently 2,4,6,8 …”

“…In the present study, the incidences of the lingual nerve below and above the submandibular duct were 99.4% and 0.6%, respectively. There was only 1 study that showed sides of the lingual nerve crossing above the submandibular duct 8 . Of the 8 sides, right and left sides were 4 and 4, respectively.…”

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.

“…The submandibular gland sits in a triangle bordered by the mandible and anterior and posterior digastric muscles, which drain to Wharton’s duct [ 2 ]. Variance in anatomy must be carefully considered, as understanding patterns of anatomy and relation of lingual nerve, hypoglossal nerve, and submandibular ducts is the most important factor in reducing nerve damage during surgery [ 18 ].…”

Submandibular gland injury is a rare occurrence that has been only documented in case reports. This is due to its protected location under the mandible, and only penetrating injuries to the floor of the mouth or trauma underneath the mandible can reach and damage it. While pediatric injuries due to non-powder firearms are decreasing yearly, 80.8% of the injuries were due to ball bearing (BB) guns. This case report explores the diagnosis and management of a 16-year-old girl who presented with a BB gunshot wound to the submandibular gland. The anatomy, imaging, and surgical management are detailed, and diagnosis guidelines and treatment options are analyzed and explained. This case highlights the importance of understanding the harm that non-powder firearms are capable of causing despite being perceived as toys.
