“…The lingual foramina (LF) and their bony canals (LCs) are located at the internal surface of the anterior region of the mandible. [ 1 ] Studies conducted on cadavers have shown that branches from the sublingual and/or submental arteries go through these anatomic structures. [ 2 ] Therefore, despite being generally considered as a safe area when performing surgical procedures, this mandibular region may present real life-threatening hemorrhage from the above cited arterial branches following the lingual cortical plate trauma.…”

Objective:The aim of this study was to evaluate the mandibular lingual foramina (LF) and canals and their anatomic variations using cone-beam computed tomography (CBCT) technology in a Lebanese population.Materials and Methods:In this study, we analyzed CBCT images of 90 adult Lebanese patients (41 males and 49 females). We assessed the number and location of the LF. In additional, we measured: (a) The distance from both the alveolar crest and the inferior border of the mandible to the LF and (b) the length of the lingual canals (LCs). The data obtained was analyzed statistically using Shapiro–Wilk normality test, t-test, Chi-square, and Fisher's exact tests. Statistical significance was set at 0.05.Results:In our sample, the LF and canals were present in 93.33% of the CBCT analyzed, and the majority (76.64%) was located above the genial tubercles. The distance from the foramen of the superior and the inferior LCs to the alveolar crest was 16.24 ± 2.82 mm and 25.49 ± 2.43 mm, respectively. The distance from the foramen of the superior canal to the inferior border of the mandible was 14 ± 2.32 mm. The mean length of the superior canal was 5.81 ± 1.6 mm and 4.25 ± 1.2 mm for the inferior one. There were no gender-related differences in the anatomic characteristics of the LF and canals except for the distance measured from the superior canal foramina to the alveolar crest where the measurement was significantly greater in males compared to females. Neither the number of canals nor the positions of the foramina were different between males and females.Conclusion:Within the limits of this study, we concluded that in our sample of Lebanese adults, there was substantial variability in the LF and canals anatomy and location.

“…The smallest size was 0.1 mm in diameter and the largest was 2.29 mm. Higher mean values were found for the superior MLF (0.75-1.12 mm) than for the inferior MLF (0.58-0.9 mm) [61]. CBCT studies found a greater height than the width in the MLF, while an inverted ratio in the LLF [62].…”

“…The average distance to the lower edge of the mandible ranged from 12 to 18.4 mm for the superior MLF and from 2.2 to 7 mm for the inferior MLF [61]. Only two studies [65,66] evaluated the distance from the MLF to the alveolar crest because measurements and comparisons are hampered by periodontal diseases or atrophic bone.…”

“…It was reported that a lingual canal associated with LLF occurs in 95% of individuals. From the axial view, LLCs usually course anterior to the foramen (43%), even if 21% also course perpendicular to the lingual bone surface of the mandible [61,62].…”

“…Lateral Lingual Foramina LLF has been less commonly evaluated than MLF and has been observed in a lower number of cadavers and patient mandibles. The frequency of LLF generally reported in the literature ranges from 6 to 80% [61]. According to a study published by Katakami et al (2009) [56], LLF is encountered with a relatively high frequency in the area corresponding to the first premolar (36%) but also in central incisor and canine areas (each 19.4%).…”

(1) Background: The anatomical variations of neurovascular canals that are encountered in oral surgery are often overlooked by anatomy textbooks or provided with insufficient information. The aim of this study is to analyze the most common variations, describing their morphology, prevalence and clinical implications. (2) Methods: A review of published literature from the 20th century onwards was performed using the PubMed electronic database as well as anatomical textbooks. The variations being investigated were: retromolar canal (RMC) and foramen (RMF), accessory mental foramen (AMF), midline (MLF) and lateral (MLF) lingual foramina and canalis sinuosus (CS). (3) Results: Anatomical variants of neurovascular canals and foramina have a significant incidence and important clinical implications in the most common oral surgery procedures such as third molar extraction, bone harvesting and implantology. (4) Conclusions: Knowledge of these variables is highly important both for students to have a more accurate anatomical awareness and for professional surgeons to be able to provide better diagnoses and prevent complications during oral surgery techniques.

Purpose: Surgical complications in the anterior mandible had been reported. These complications increase the interest into the content and the vascularity of the area. Cone beam computed tomography (CBCT) was used for investigating bony structures. The aim of this study was to evaluate the anatomical features of labial and mental foramina. Methods: Foramina on the outer surface of the anterior mandible were evaluated in coronal, sagittal, and axial planes of 104 CBCT scans. Results: Other than mental foramina, 184 foramina were observed in the labial surface of the mandible. The incidence of the labial foramina was 60.58%. Bilateral and unilateral accessory mental foramina were found in 28.85% of cases. Conclusion: Mandibular labial foramina are frequently seen in CBCT. Wide variations were seen in different neurovascular anatomical landmarks in the anterior mandible including accessory mental foramina. These findings should be considered when planning for anesthesia and surgery in this region.
