“…This means that the distance from mandibular foramen to mandibular notch (MF-MN) was close in males to females. In contrast to a study conducted on a Chilean population showed that the distance from the mandibular foramen to the mandibular notch (MF-MN) in males (24.35mm) was greater than in females (22.0mm) (21) .…”

Aim: The present study designed to determine variations in mandibular foramen using CBCT in Egyptian population. Subjects and Method: 300 CBCT images were grouped according to sex, and symmetry between right and left sides into two groups. Group I: males& female and group II: right & left sides. Panoramic images were reconstructed from CBCT scans and evaluated using Blue sky software. The exact location of mandibular foramen at the two sides of the mandible was determined in relation to anterior border & posterior border of ramus, mandibular base, and mandibular notch. The recorded data will be collected, tabulated and statistically analyzed by SPSS (Statistical Package for Social Sciences). Results: This study showed bilateral asymmetry between right and left sides, no significant difference between 2 sides of the mandible. There was high significant difference in the distance from MF to mandibular base between males and females. No significant difference in other parameters relative to vertical and horizontal dimensions of mandibular ramus. Conclusions: All parameters related to the position of mandibular foramen in vertical and horizontal dimensions of mandibular ramus (MF-MB), (MF-MN), (PB-MF), and (AB-MF) were symmetrical in the right and left sides. The distance from mandibular foramen to mandibular base (MF-MB) was greater in males than females.

“…We have not found the assimilated shape for black individuals, and for white individuals this shape was found in only 3.1 %. The literature reports important racial differences in studies with mandibles (Alves & Deana, 2014), however we did not find any other study correlating race and shape of lingula.…”

Analysis of the lingula shapes in macerated mandibles of Brazilian individuals. Int. J. Morphol., 34(1):42-48, 2016. SUMMARY:The lingula of the mandible is a bone projection that limits medially the mandibular foramen, which is the region where the inferior alveolar neurovascular bundle penetrates. The lingula is an important anatomical landmark used in maxillofacial surgeries and to block the inferior alveolar nerve. The aim of this study was to analyze the different types of lingula found in mandibles of Brazilian individuals, considering aspects such as gender and race. One hundred thirty-two macerated mandibles of Brazilian adult individuals of both sexes, black and white skin colors, were used. The lingula was classified into four types: triangular, truncated, nodular and assimilated. The data were analyzed using Chi-square test and Fisher's exact test. The truncated shape was the most commonly found (49 %), followed by nodular (26.5 %) and triangular (23.3 %) shapes. The assimilated shape was significantly less prevalent with 1.2 %. Each type of the lingula was more often bilateral rather than unilateral. Considering skin color we observed that the truncated shape was more prevalent in black individuals than in white individuals and the nodular shape was more prevalent in white individuals than in black individuals. There was no case of assimilated shape in black individuals. Considering gender we observed that the truncated shape was more prevalent in females than in males and the triangular shape was more prevalent in males than in females. The lingula shape showed no side preference. Our findings facilitate the planning of oral and maxillofacial surgical procedures that involve the lingula and/or the inferior alveolar neurovascular bundle, avoiding operative complications.

“…Based on our results, we emphasize that in planning a surgery involving the region of lingula, such as sagittal split ramus osteotomy (SSRO) technique, the surgeon must take into account aspects such as gender, race, and shape of lingula. Another important issue that should be considered is a possible anatomical variation in the medial region of the ramus of mandible, where there may be an accessory mandibular foramen located above the lingula [ 21 , 22 ] or near the mandibular notch [ 23 ]. Such variations are not common but result in increased risk of complications involving the inferior alveolar nerve [ 21 ].…”

Objectives. The purpose of this research was to study, in macerated adult human mandibles, the height of the lingula and provide morphometric data for its location considering aspects such as shape of the lingula, gender, and race. Material and Methods. 132 macerated mandibles of Brazilian adult individuals, both sexes, Amerindian and Caucasian, were used. The distances: from mandibular notch to lingula; from anterior margin of ramus of mandible to lingula; from posterior margin of ramus of mandible to lingula; from mandibular base to lingula, and the height of lingula were obtained. To perform these measurements we used a digital caliper. The variables such as gender and race were analyzed. Results. The mean values found for the height of lingula and its location were determined according to the gender, race, and the lingula shape. Conclusion. This research provides additional data on height of the lingula and morphometric data for its location considering aspects such as shape of the lingula, gender, and race, information that had not been reported in the literature to date. We emphasize that a careful study considering gender and ethnic group makes procedures involving the region of lingula safer.

Morphometric study of mandibular foramen in macerated skulls to contribute to the development of sagittal split ramus osteotomy (SSRO) technique

Abstract: The values found in this study, considering gender, age and ethnic group, can be used as a parameter to carry out the sagittal split ramus osteotomy technique, making it more predictable and with less risk of complications.
