PURPOSE The purpose of this study was to evaluate changes in the mandibular canal and ramus morphology before and after a sagittal split ramus osteotomy. PATIENTS AND METHODS The subjects were 30 patients (60 sides) with mandibular prognathism who had undergone bilateral sagittal split ramus osteotomy setback surgery. The mandibular canal position and ramus morphology were measured at the 3 h...

The absolute and relative breadths of the mandibular ramus (MRB) display substantial variation in modern humans, and are of analytical value in paleoanthropology. According to Enlow et al. ([1969] Am. J. Orthod. 56:6-23), the ramus is the growth counterpart of the middle cranial fossa (MCF) and the pharynx. Such counterpart principles state that variation in ramus breadth is a frequent function...

At the Specialty Clinics of Georgia we have been evaluating the comparative efficacy of the Gray Ramus Communicans Nerve Block for the treatment of painful osteoporotic vertebral compression fracture. The relative frequency of Thoracic and Lumbar fractures being equal, we began to ask the question why was the utilization of the Gray Ramus Communicans Nerve Block more frequent for a lumbar verte...

Myxofibroma is a rare tumor. Three cases of myxofibroma, each of which developed at the right mandibular ramus, mandibular anterior tooth region, are presented. Myxofibroma developing in the mandibular ramus region is rare, and there has been only one case reported so far in Japan.

High Q frequency reference devices are essential components in many Integrated circuits. This paper will focus on the Resonant Suspended Gate (RSG) MOSFET. The gate in this structure has been designed to resonate at 38.4MHz. The MOSFET in this device has a retrograde channel to achieve high output current. For this purpose, abrupt retrograde channel and Gaussian retrograde channels have bee...

introduction: raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. the aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging. materials and methods: in this descriptive study, the facial ct scans were obtai...

Many chronic pain conditions including complex regional pain syndrome are exacerbated by sympathetic activity. In animal models, sympathetic fibers sprout into the dorsal root ganglia (DRG) after peripheral nerve injury, forming abnormal connections with sensory neurons. However, functional studies of sympathetic-sensory connections have been limited largely to in vivo studies. This study descr...

The present study investigated the validity of mandibular ramus flexure in sex differentiation among young Jordanian adults using Orthopantomographic images in a double blind study. A normative sample comprised of 419 images was selected, of which 126 belonged to male patients and 293 images to females. The exclusion criteria used in the selection involved excluding images that showed marked lo...
