Considerable variation exists in mandibular ramus form among primates, particularly great apes and humans. Recent analyses of adult ramal morphology have suggested that features on the ramus, especially the coronoid process and sigmoid notch, can be treated as phylogenetic characters that can be used to reconstruct relationships among great ape and fossil hominin taxa. Others have contended tha...

PURPOSE The purpose of this study was to measure the anteroinferior changes and the degree of vertical changes to facilitate the prediction of treatment outcome in patients undergoing genioplasty only, genioplasty with bilateral sagittal split ramus osteotomy (BSSRO), genioplasty, or BSSRO and Lefort I osteotomy. MATERIALS AND METHODS Serial cephalometry was performed on 25 patients at 1-year...

Coronary artery (CA) disorders are among the major causes of morbidity and mortality in humans. We attempt to explain CA anatomy its variations a simple, concise, understandable way help clinicians deal with various disorders. There two main arteries: right coronary (RCA) left CA. The bifurcates into terminal branches: anterior descending (LAD) circumflex (LCX). commonest anatomical variant is ...

Case Report A 72-year-old man with hypertension, hyperlipidaemia, diabetes and renal impairment presented with recurrent heart failure from a severely leaking mitral bioprosthesis. He had undergone 2 previous coronary bypass operations, 25 years and 7 years ago respectively. His porcine mitral valve implanted during his most recent bypass surgery was severely regurgitant from a fl ail leafl et ...

Cutting balloon angioplasty (CBA) is one of the adept ways of treating "in-stent restenosis." Various complications related to cutting balloon angioplasty have been reported including arterial rupture, delayed perforation and fracture of microsurgical blades. Here we report a very unusual and inadvertent extraction of a stent previously deployed in the ramus intermedius coronary branch by a cut...

The variability of the craniofacial skeleton of the juvenile Macaca mulatta was studied from lateral radiographic cephalograms of twenty-three animals, using a previously described method based on fourteen lines depicting certain anatomic features. The findings, when compared to corresponding human data, revealed that a number of angular relationships are similar in this monkey and in human ch...

INTRODUCTION Facial phenotype is influenced by genes and environment; however, little is known about their relative contributions to normal facial morphology. The aim of this study was to assess the relative genetic and environmental contributions to facial morphological variation using a three-dimensional (3D) population-based approach and the classical twin study design. MATERIALS AND METHO...

A partial mandible of a large lorisid primate is described. The specimen (YPM 19134) comes from probable late Miocene deposits in northeastern India and consists of a fragment of a left mandibular ramus containing M3, the roots of M2 and the posterior root of Mi. The third molar resembles the M3 of modern Nycticebus coucang borneanus; the specimen is referred to Indraloris cf. lulli. Unfotunate...

PURPOSE The objective of this study was to evaluate morphological changes of the mandible in edentulous and dentate subjects using panoramic radiographs. MATERIALS AND METHODS Panoramic radiographs were divided into the following three groups: Group I (completely edentulous group), Group II (old dentate group) and Group III (young dentate group). The research parameters of gonial angle, condy...
