anatomical study of the location of the antilingula lingula and Mandibular Foramen for vertical ramus osteotomy
Maxillofacial plastic and reconstructive surgery, 2018Co-Authors: Jin Hoo Park, Hwidong Jung, Hyung Jun Kim, Youngsoo JungAbstract:The purpose of this study was to identify the location of the antilingula, lingula, and Mandibular Foramen in Korean cadavers and to promote safe and accurate surgery without damage to the inferior alveolar neurovascular bundle (IANB) when performing a vertical ramus osteotomy (VRO). This study was conducted on the dried mandibles of 20 adult cadavers. Digital calipers were used to measure the distances from the anatomical reference points (antilingula, lingula, and Mandibular Foramen). The antilingula was located at the anterior 44% and superior 31% in the ramus. The lingula was located at the anterior 55% and superior 30% in the ramus. The Mandibular Foramen was located at the anterior 58% and superior 46% in the ramus. Regarding the positional relationship with the antilingula, the lingula was located 0.54 mm superior and 4.19 mm posterior, and the Mandibular Foramen was located 6.95 mm inferior and 4.98 mm posterior. The results suggested that in order to prevent damage to the IANB, osteotomy should be performed in the posterior region of ramus at least 29% of the total horizontal length of the ramus. Using only the antilingula as a reference point is not guaranteed to IANB injury. However, it is still important as a helpful reference point for the surgeon in the surgical field.

changes in the location of the human Mandibular Foramen as a function of growth and vertical facial type
Acta Odontologica Scandinavica, 2015Co-Authors: Jeanfrancois Epars, Anestis Mavropoulos, Stavros KiliaridisAbstract:AbstractObjective. A previous cross-sectional investigation showed that the Mandibular Foramen location depends on the age and the vertical facial pattern of growing individuals. The aim of the present longitudinal study was to explain how these factors influence the distance between the Foramen and the occlusal plane. It is known that a certain distance is necessary for a successful inferior alveolar nerve block in clinical dentistry. Materials and methods. This distance, as well as another four cephalometric variables, were measured on both pre-treatment and 10-year post-treatment lateral cephalometric radiographs collected from 50 patients who underwent orthodontic treatment. The changes between these two sets of measurements were also calculated. Results. A multiple regression analysis was performed using the pre-treatment age, the pre-treatment inter-maxillary angle, the rotation of the occlusal plane and the change in Mandibular ramus height as independent variables and the change of Foramen-occlusa...

influence of age and vertical facial type on the location of the Mandibular Foramen
Pediatric Dentistry, 2013Co-Authors: Jeanfrancois Epars, Anestis Mavropoulos, Stavros KiliaridisAbstract:A successful inferior alveolar nerve block anesthesia necessitates knowledge of the exact location of the Mandibular Foramen. The aim of this study was to determine whether the location of the Mandibular Foramen is related to the age or the vertical facial morphology of the patient.

morphometric study on Mandibular Foramen and incidence of accessory Mandibular Foramen in mandibles of south indian population and its clinical implications in inferior alveolar nerve block
Anatomy & Cell Biology, 2016Co-Authors: R Shalini, C Ravivarman, R Manoranjitham, M VeeramuthuAbstract:The Mandibular Foramen is a landmark for procedures like inferior alveolar nerve block, Mandibular implant treatment, and Mandibular osteotomies. The present study was aimed to identify the precise location of the Mandibular Foramen and the incidence of accessory Mandibular Foramen in dry adult mandibles of South Indian population. The distance of Mandibular Foramen from the anterior border of the ramus, posterior border of the ramus, Mandibular notch, base of the mandible, third molar, and apex of retromolar trigone was measured with a vernier caliper in 204 mandibles. The mean distance of Mandibular Foramen from the anterior border of ramus of mandible was 17.11±2.74 mm on the right side and 17.41±3.05 mm on the left side, from posterior border was 10.47±2.11 mm on the right side and 9.68±2.03 mm on the left side, from Mandibular notch was 21.74±2.74 mm on the right side and 21.92±3.33 mm on the left side, from the base of the ramus was 22.33±3.32 mm on the right side and 25.35±4.5 mm on the left side, from the third molar tooth was 22.84±3.94 mm on the right side and 23.23±4.21 mm on the left side, from the apex of retromolar trigone was 12.27±12.13 mm on the right side and 12.13±2.35 mm on the left side. Accessory Mandibular Foramen was present in 32.36% of mandibles. Knowledge of location Mandibular Foramen is useful to the maxillofacial surgeons, oncologists and radiologists.

osteotomy in the vertical ramus outside the Mandibular Foramen for tumours in the parapharyngeal space
Journal of Cranio-maxillofacial Surgery, 2014Co-Authors: Weiliang Chen, Weijian Wang, Zhiquan Huang, Daming ZhangAbstract:Abstract Introduction Although several techniques have been described to access the parapharyngeal space, tumour surgery in this area remains a challenge. This study investigated a simple and safe technique to access parapharyngeal space tumours. Material and methods Eight primary parapharyngeal space tumours were treated with osteotomy of the vertical ramus outside the Mandibular Foramen. The primary tumours were pleomorphic adenoma, schwannoma, Warthin's tumour, lipoma, chordoma, and adenoid cystic carcinoma. Tumour size ranged from 4 × 4 cm to 6 × 7 cm. Patients with malignant tumours who underwent surgical resection also received adjuvant dose-fractionated stereotactic radiotherapy. Results All tumours were removed completely without rupture. No patient exhibited any permanent postoperative complication, malocclusion, or other dental complications from this surgical approach. One patient had slight transient postoperative facial paresis, which resolved spontaneously within 4 weeks. The patients were followed for 7–26 months, during which no recurrence was encountered. Conclusions Osteotomy of the vertical ramus outside the Mandibular Foramen achieved good exposure and satisfactory aesthetic and functional results. This simple and safe technique facilitates the removal of infratemporal fossa tumours while preserving the inferior alveolar nerve.
