“…Reyneke et al, 13 Precious et al 9 and Mehra et al 14 indicated an increased risk of an unfavourable split with unerupted third molar teeth. Previous studies have recommended the removal of unerupted lower third molar teeth at least 6 months prior to the surgical procedure.…”

The authors undertook a prospective study to evaluate the influence that the anatomical dimensions of the ramus of the mandible and the presence of lower third molar teeth may have on the sagittal split ramus osteotomy. The anatomical dimensions measured included the width of the anterior mandibular ramus, the height of the corpus posterior to the second mandibular molar and the antero-posterior anatomical position of the lingual. The influence that these dimensions of the mandible may have on the successful splitting of the mandibular ramus wasThe effect that the presence of wisdom teeth had on the difficulty of the procedure was also investigated. This study found that, unlike the presence of third molars, there was no single anatomical measurement that contributed to the level of difficulty of the sagittal split osteotomy. For descriptive purposes the authors proposes a classification of the four typical patterns of unfavourable splits.

“…The majority of patients show no post-extraction complications and fully recover after a brief healing process. In rare cases, osteotomy can lead to neurological problems including neuralgia or impaired sensibility not only in the area of the inferior alveolar, but also in the entire area of the trigeminal nerve [1]. In a recent prospective study, 1.3% of the extractions caused temporary nerve damage; 25% of the lesions were permanent [2].…”

The objective of this study was to assess whether signal changes can be detected in the neurovascular bundle of the mandibular canal after the extraction of a third molar. We retrospectively analyzed MRI scans of 30 test subjects with healthy mandibles and 41 patients who had had a wisdom tooth extracted. Signal intensities were measured at particular sites in the neurovascular bundle, which were defined as regions of interest (ROI) in the sagittal T1-weighted images before and after intravenous administration of a paramagnetic contrast agent. On the basis of the signal intensity increases that were measured after contrast agent administration, we compared the signal increases obtained for the patients who had received surgical treatment with the results obtained for the population of test subjects with unremarkable mandibles ( t-test, P<0.05). Compared with the healthy test subjects, patients who had received surgical treatment showed significantly higher signal intensity increases at two measurement sites, i.e., the second molar and the second premolar ( P<0.05). We found no significant differences when the measurements were performed at the first molar ( P=0.06), the third molar ( P=0.47) and in the area of the ascending mandibular ramus ( P=0.79). Compared with a population of healthy test subjects, patients who had their third molars surgically removed show higher signal intensity increases in the neurovascular bundle after intravenous contrast agent administration. The underlying cause may be the higher blood flow in the arteries and veins and the perineural plexus, which may give evidence of the pathophysiological mechanism of nerve damage in the narrow canal as a result of osteotomy.

“…In the present study the retromolar foramen was seen in 6 % of specimens which is almost similar to study by Sawyer and Kiely. The inferior alveolar neurovascular bundle may be injured in the surgical procedures, like surgical extraction of lower third molars, or in the sagittal split osteotomy surgery, on account of its vulnerable location [14].…”

Background and Objectives The mandibular foramen and the lingula, because of their relation to the inferior alveolar nerve are of clinical significance for the orodental surgeons. Identification of the antilingula is important in mandibular ramus surgery in which the medial surface of the ramus is not visualized. Methods The present study includes adult dry 50 mandibles of unknown age and sex. The measurements were taken using vernier calipers. The points taken for measurements were most prominent point on antilingula, tip of lingula, most anterior, posterior and inferior points of mandibular foramen. The measurements were denoted as A, B, C and D which represent the anterior, posterior, superior and inferior distances. Results Antilingula was present on right side in 25 and on left side in 28 mandibles. There was a significant difference in distances in mean between the antilingula and mandibular foramen of both the sides (p \ 0.001). Retromolar foramen was observed in 6 mandibles. Mylohyoid bridging was seen in 3 mandibles. Conclusion The mandibular foramen was located posterosuperior to the antilingula on both the sides. There was no statistical significance in the distances between the lingula and the antilingula. Therefore antilingula can be used as an important surgical landmark for locating the mandibular foramen in mandibular ramus osteotomies.
