among the rare bone tumors, the osteoblastoma is a fascinating tumor. the rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. it is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. the unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...

BACKGROUND This study aimed to determine if mandibular parameters (gonial angle, bigonial width and ramus height) measured from panoramic radiographs, can be used to determine a correlation with an individual's age and gender in dentate subjects in Far North Queensland. MATERIAL AND METHODS The study utilised 2699 randomly selected panoramic radiographs of patients between the ages of 19-69 y...

The treatment of pubic ramus nonunion is usually surgical. We report the successful healing of a hypertrophic nonunion of pubic ramus in a 46 year old active male patient who was treated conservatively with a lumbo-sacral corset. We believe that understanding the injury mechanics in pelvic injury is more important to employ a particular treatment method than to follow the conventional ways of t...

The arterial distribution within the mandible and maxillae, which are the only structures having teeth, is more complicated than that of other bones. The whole mandible, including the teeth, is nourished chiefly by the inferior alveolar artery. The mandibular ramus receives small vessels not only from the inferior alveolar artery, but also from the mandibular branch of the maxillary, the poster...

We found a rare case of uncommon branching pattern with a prominent articular ramus of the inferior gluteal artery in a 39-year-old Korean male cadaver, whose cause of death was rectal carcinoma. The inferior gluteal artery branches off downwards at a time, the muscular rami ran in parallel with one another, and the articular ramus gave another muscular branch and has an anastomosis with the me...

BACKGROUND Conventional fluoroscopically guided continuous radiofrequency (CRF) and pulsed Radiofrequency (PRF) lesioning of the medial branch, dorsal ramus, a standard technique to treat facet pain, is compared to an endoscopic visually guided technique. The endoscopic technique (Figure 1) is designed to ablate a larger area of the transverse process where the medial branch crosses to innervat...

The purpose of this study was to evaluate hypoesthesia of the lower lip using trigeminal somatosensory-evoked potential following 2 types of sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy (IVRO). There were 30 patients with mandibular prognathism, with and without asymmetry, who were divided into three groups: the Obwegeser method (Ob) group, the Obwegeser-Dal Pont...

Linear mouth opening is often used to assess the limitation of mandibular movement. However, this has a number of limitations. It is dependent on variables such as age, gender and ramus length. A new measure of movement has been developed previously, called the temporomandibular opening index (TOI). Forty-two subjects who did not exhibit signs and symptoms of temporomandibular disorder (TMD) we...

Myanmarorchestia victoriasp. nov. is described from high altitude habitats in Myanmar. The new species differs morphologically from its congeners by palp of maxilliped narrow; sexually dimorphic gnathopod Ⅱ, propodus of male chelate and propodus of female mitten-shaped; and dimorphic uropod Ⅱ, outer ramus of male with small teeth distally, outer ramus of female with three distal spines. Analysi...
