Radiological and Microsurgical Anatomy for Variation of the Mandible: Comparative Study of Human and Macaca fascicularis.

摘要: Recent studies using cone-beam computer tomography (CBCT) have added to our understanding of anatomical variation in the mandible humans. However, distribution nerves cannot be revealed by CBCT. There been investigations relating mandible, but some proposed causes these variations remain controversial. In this study, we observed a total 10 sides from five mandibles Macaca fascicularis unknown age and sex CBCT dissection under stereomicroscopy. Nine had two mental foramina each side. Innervation depended on locations those foramina. The long branch mandibular angle ran with facial artery, which joined artery all sides. Five specimens median perforating canal bone. addition, sublingual small branches submental entered bone lingual foramen. This foramen was located lower part symphysis passed via exit labial foramen, also symphysis. We speculate that rarely found humans, is remnant feeding fetal M. seen because they no protuberance.
