A young adult male was admitted after suffering polytrauma due to road traffic accident. Emergency radiography showed pelvic fracture. Computed tomography (CT) scan was performed which revealed presence of comminuted displaced fracture of left superior pubic ramus. Fracture line was extending till pubic symphysis but no symphyseal diastasis was noted. In addition, a part of urinary bladder was ...

A partir da tentativa de aproximar a história do ensino Matemática por meio antigos instrumentos para mobilização conhecimento matemático presente neles, tivemos aplicação uma atividade em um curso extensão universitária, no qual visamos mostrar os conhecimentos geométricos que foram elencados estudo dos condicionantes manipulativos báculo Petrus Ramus (1515-1752), instrumento contido documento...

Soft tissue changes following correction of mandibular hyperplasia were studied using a laser system for three-dimensional (3-D) surface measurement. Twelve subjects (7 men and 5 women; age 17-48 years) were included in this study. Bilateral sagittal split ramus osteotomies were performed in ten patients and intraoral vertical ramus osteotomies in two patients. Pre- and postoperative images, ob...

This study compares temporomandibular joint dysfunction (TMD) symptoms before and after bilateral sagittal split ramus osteotomy, and identifies predictive factors for the postoperative TMD symptoms by assessing the adjusted odds ratio using multiple logistic regression analysis. A consecutive series of 37 cases treated only with bilateral sagittal split ramus osteotomy were evaluated. New post...

Since Ramus et al. (1999) a number of statistical metrics have been routinely employed by researchers (Ramus 2003, Grabe & Low 2002 etc.) in an effort to rhythmically classify languages. However, recent studies by Arvaniti (2009), Tilsen & Arvaniti (2013), Arvaniti & Rodriquez (2013) etc., have challenged both the validity of these metrics in reflecting speech rhythm, and the physical measurabi...

The purpose of this study was to investigate the position of the mandibular foramen from deciduous (Hellman's stage IIA) to early permanent dentition (Hellman's stage IVA). Panoramic radiographs of 311 Taiwanese children were used. The results revealed that the distances between the mandibular foramen and ramus anterior plane were greater than those between the mandibular foramen and ramus post...

The posterior superior alveolar (PSA) nerve block is, from an anatomical perspective, challenging because the mandibular ramus and the zygomatic process of the maxilla can interfere with the course of the needle. Dentists empirically know that shifting the patient's mandible to the ipsilateral side can improve visibility and accessibility for such blocks. This cadaveric study aimed to establish...

lntraosseous hemangiomas are benign tumors occurring most often in the skull and vertebrae. Rarely , these lesions can present in the maxilla and mandible. We found in the literature a case of an intraosseous hemangioma involving the mandibular condyle (1 ). We wish to report the panoramic zonographic, computed tomographic, and pathologic findings of another case involving both the condyle and ...
