The radiological characteristics of the lingual foramen

Abstract Background Hemorrhages, mouth floor edema and tongue elevation are complications related to surgical procedures in the anterior region of the mandible. Objective The objectives of this study were to evaluate the presence and location of the lingual foramen in the anterior region of the mandible and to evaluate mandibular morphology using cone beam computerized tomography (CBCT). Material and method The mandible’s morphology and the location, diameter and height of the lingual foramina were analyzed using the midline and the mental foramen as references, in 278 CBCT. Result 88% of the sample had a midline lingual foramen, totaling 408 foramina, with a mean diameter of 0.93 mm. Foramina in the lingual region between the midline and mental foramina were detected in 75% of the sample, with a mean diameter of 0.807 mm. There was no positive correlation between the presence of lingual foramina in the lateral or in the midline regions (r = -0.149; p = 0.013). In the midline region, the type I mandibular shape was predominant (96%), and type III was predominant in the lateral regions. Conclusion Considering the prevalence of these structures and their clinical relevance in potential surgical complications, it is important to carefully analyze the anterior region of the mandible during surgical planning.

Objectives: Lingual foramen (LF) is an important landmark of the mandible, which should be considered in presurgical assessment. The purpose of this study was to assess the anatomical variations of the LF using cone-beam computed tomography (CBCT). Materials and Methods: The study was conducted on 200 CBCT scans of Iranian adults. The lingual foramina (LFs) were classified into two groups by their location in the mandible namely the medial LFs (MLFs) and the lateral LFs (LLFs). The frequency of both the MLFs and the LLFs and their distance from the inferior border of the mandible were evaluated. Additionally, the diameter of the MLFs and the location of the LLFs were assessed. Data were analyzed separately for males and females. Results: All 200 participants had at least one LF. Totally, 257 LFs were detected on 200 CBCT scans, including 223 MLFs (86.6%) and 34 LLFs (13.3%). The LLF was detected in 23 patients (11.5%). The prevalence of the LLF was higher in males and in the second premolar region. The diameter of the MLFs was less than 1mm in 81% of the cases, and males had a larger MLF. Conclusion: There was a significant variability in the anatomy and location of the mandibular LF in Iranian adults. CBCT is recommended for preoperative imaging to determine the exact location and size of the LFs in the mandible to prevent possible surgical complications.
