“…Other aspects of the splits were also roughly similar. Mensink et al 17 also reported a reliable splitting pattern after BSSO using sagittal splitters and separators, without an increased risk of bad splits, which was confirmed by clinical studies. 13,18 The conventional osteotomy design has been used since 1968.…”

“…The mandibular lingula limits the foramen medially (Alves and Deana, ), and is the attachment of the sphenomandibular ligament, clinically important for oral and maxillofacial surgeons during saggital split ramus osteotomy as a landmark for avoiding nerve injury, hemorrhage and unfavorable fractures (Jansisyanont et al, ). There is a shallow groove (or sometimes a partial canal, or a small bone bridging) located posterior to the lingula called the mylohyoid groove (Narayana et al, ; Mensink et al, ), in which the mylohyoid nerve, a small branch of the inferior alveolar nerve, penetrates. There are many variations of this groove, and Fabian () concluded that the sphenomandibular ligament on the lingula and/or medial wall of the mandibular foramen leads to variations in its location.…”

Cone-beam computed tomography gives us much useful morphological information about the mandibular bone. Many studies of the mandible include findings from this technique. However, there have been no endoscopic studies of the mandible. Sixteen sides of eight dry mandibles resected from cadavers (age range 38-83 years) were examined by endoscopy. The head of the endoscope was 2.0 mm in diameter. We examined the mandibular foramen, lingula, mylohyoid groove, and mandibular canal. The mylohyoid grooves showed variations such as double grooves and canals. The mandibular lingula was located superior or medial to the the mandibular foramen. In a single case, the medial wall inside the mandibular canal showed a porous surface. The retromolar canal was observed in three sides. None of the images in the present study have been seen in other studies. Observation of the retromolar canal from the mandibular canal in particular can help dental students as well as oral and maxillofacial surgeons to understand its morphology.

“…20 Previous studies in cadavers have measured the anatomical configurations of key mandibular structures and their implications on surgical complications. 20,21 Actually CT scans can provide a reliable information and precise linear measurements 22 and a comparative study presented that the difference between real value and tomographic value is <0.1 mm in 81% of cases. 23 Previous studies just considering the thickness of the cortical bone found results ranging from 1.59 to 3,03 mm, 24 which is not safe for the clinical application of current fixation systems, where the minimum length of the screws is 4 mm.…”

The aim of this study was to measure the thickness of the mandible from the external cortical plate to the teeth roots on premolar and molar regions using CT scan to determine the safety margin for the application of monocortical screws for internal rigid fixation. Thirty-one patients underwent CT-scan imaging for surgical planning. The images were used to measure bilaterally the distance from the external cortex of the mandible to the roots of teeth on premolar and molar region by means of Dental Slice software (Bioparts Prototipagem Biomedica, Brasília, DF, Brazil). Mean, median, standard deviation, one-way ANOVA and post hoc Tukey's test were used for statistical analysis. No statistical differences for thickness were found between right and left side ( p = 0.1652). The mean thickness for the left side was 4.17 ± 1.68 mm and for right side 3.93 ± 1.49 mm. Increase in mandibular thickness from anterior to posterior regions in both sides was observed and statistical difference was found among the different groups according to the measured region ( p < 0.05). The present results can predict the safety zone for the use of monocortical screws in the mandible, but the use of CT scan is imperative and individual analysis is desired owing to anatomical variations. Further studies with larger samples are necessary to confirm these data and should include other anatomic structures, different regions of mandible/maxilla, as well as other ethnic groups.
