Combined upper alveolectomy and segmental mandibulectomy are complex defects. Reconstruction of these defects is usually suboptimal. We describe the case of a pediatric patient with vessel-depleted neck with recurrent vascular malformation involving the ramus and coronoid process of mandible and a previous history of maxillectomy and a reconstruction with anterolateral thigh flap. The patient underwent wide resection. The defects involving the upper alveolus and mandible were simultaneously reconstructed with a single free fibula flap...

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth...

PURPOSE: Coronoidotomy is used to treat several conditions, including coronoid hyperplasia and temporomandibular joint (TMJ) ankylosis. The stability of the outcome, however, is considered questionable because of the risk of reattachment of the coronoid process. This study aims to radiographically and clinically evaluate the long-term anatomic and physiological outcome after coronoidotomy. MATERIALS AND METHODS: In 17 patients with unilateral TMJ ankylosis, 25 coronoidotomies were performed as an additional maneuver to relieve trismus after ankylosis release...

The supratrochlear foramen (STF) is an important and relatively common anatomic variation in the lower end of the humerus in humans. The present study on south Indian population is an attempt to highlight the incidence, morphological features and clinical importance of STF. The study was conducted on dried human humeri of unknown sex and free of pathological changes. The presence of a STF was noted for its shape and divided into three types (oval, round, and irregular). In bones where the foramen was absent the translucency of the septum between the coronoid and the radial fossa was noted by placing the lower end of the humerus against the X-ray view box...

INTRODUCTION: The identification of human skeletal remains plays a crucial role in forensic investigation and its accuracy depends on the available parts of the skeleton. The mandible is the hardest and strongest bone of the skull, which exhibits a high degree of sexual dimorphism and helps to identify the sex in human remains. The aim of this study was to develop discriminant function to determine sex from the mandibular radiographs in a South Indian (Visakhapatnam) population. MATERIALS AND METHODS: This retrospective study consisted of 384 (192 males and 192 females) digital orthopantomographs (OPGs) divided into five groups according to age...

This study was aimed to demonstrate the specific anatomical features of the skull bones of Nehring's blind mole rats. Eight skulls, belonging to animals of both sexes, were used. The occipital squama contributed to the formation of the caudal portion of the skull roof. The foramen magnum was quite large. The external occipital crest was present only in the males. The parietal bones formed the middle portion of the skull roof together with the well-developed inter-parietal bones. The zygomatic process of the temporal bone formed the zygomatic arch by extending to the temporal process of the zygomatic bone...

BACKGROUND: The ulnar coronoid process plays a central role in maintaining elbow stability. Some of its fractures were often combined with injury of bone and ligament. Arthroscopy enables perfect visualization to allow anatomical repair. METHODS: From January 2012 to December 2013, six patients (four males, two females) with a mean age of 26.6 years were treated. The left and right ulnas were involved in two and four patients, respectively. All patients suffered from ipsilateral subluxation of the elbow without associated radial fracture...

BACKGROUND: Persistent elbow instability associated with coronoid deficiency is a difficult condition to treat. Several surgical techniques have been described for coronoid reconstruction, but the resulting outcomes have been unpredictable. We hypothesized that a coronoid prosthesis could restore elbow stability. METHODS: A nonanatomically shaped metallic coronoid prosthesis was custom designed for each of 3 patients. Each had a chronic fracture-subluxation with persistent instability, deficiencies of the coronoid, and compromise of the radial head...

BACKGROUND: Radial head fractures make up approximately 3% of all fractures and they are the most common elbow fracture in adults. Replacement through arthroplasty is the recommended treatment in the context of unstable elbow injury and comminuted radial head fracture. The midterm clinical, functional, and radiographic results in patients treated with anatomic radial head arthroplasty for a Mason type III radial head fracture are presented. MATERIAL AND METHODS: We performed a retrospective search of our facility's prospective trauma database to identify all skeletally mature patients who were treated by primary radial head replacement or open reduction and internal fixation following an acute radial head fracture...
