IMPORTANCE Classically, pterygoid plate fractures have been associated with fractures of the mid-face and skull base. When isolated pterygoid plate fractures are identified on imaging that only extends to the level of the skull base, other related facial fractures may be missed. We sought to evaluate isolated lateral pterygoid plate fractures on computed tomography (CT) scans in conjunction wit...

BACKGROUND Generally, scapula process fractures (coracoid and acromion) have been treated nonoperatively with favorable outcome, with the exception of widely displaced fractures. Very little has been published, however, regarding the operative management of such fractures and the literature that is available involves very few patients. Our hypothesis was that operative treatment of displaced ac...

We report a case of foreign body presence in the ethmoid sinus cavity with anterior skull base fracture and visual loss. A 42-year-old male had an uncertain history of trauma and a penetrating wound near the left medial canthus. Computed tomography imaging showed a 3.0-cm bottle cap penetrating into the anterior skull base. He underwent foreign body removal, canalicular repair, ethmoidectomy, a...

Cases Traumatic intracranial aneurysm following blunt head injury is uncommon but can be induced by extension of skull base fracture and causes unexpected hemorrhagic complications. We present two cases of traumatic intracranial aneurysm in the paraclinoid area that was revealed by delayed massive epistaxis. Lack of initial neurological deficits omitted screening for cerebrovascular injury. O...

INTRODUCTION Isolated trapezium fractures accounts for 3-5% of all carpal fractures, are often missed on initial presentation. Trapezial fractures should be treated early given its importance in grip and pinch. We report a rare isolated coronal fracture of trapezium, following fall on an outstretched hand. CASE REPORT A 40-year-old right lady presented with pain in right hand due to fall on o...

The low cycle fatigue response of a single crystal γ′-containing CoNi-base superalloy has been investigated in air and vacuum at 950 °C. performance is demonstrated to be similar the 1st-generation Ni-base AM1. Fracture surface imaging cross-sections on both alloys reveal that oxidation-assisted cracking responsible for crack initiation air. improves under as transitions internal casting pores ...

A multiphase nanostructured ZrCu-base bulk alloy which showed a unique microstructure consisting of sub-micrometer scale Zr₂Cu solid solution, nano-sized twinned plate-like ZrCu martensite (ZrCu (M)), and retained ZrCu (B2) austenite was fabricated by copper mold casting. The observation of periodic morphology evolution on the fracture surface of the multiphase nanostructured ZrCu-base alloys h...

We report a rare case of intracerebral pneumocephalus. It was not accompanied by the typical craniofacial skull base fracture. A 77-year-old woman presented with pneumocephalus following a pedestrian traffic accident. Neurologic and physical examination revealed multiple extensive emphysemas, multiple rib fractures, and lung contusions, but no facial or skull bone fractures. Computed tomography...

PURPOSE This in vitro study investigated the fracture resistance of endodontically treated premolars restored using silorane- or methacrylate-based composite along with or without fiber or nano-ionomer base. MATERIALS AND METHODS Ninety-six intact maxillary premolars were randomly divided into eight groups (n = 12). G1 (negative control) was the intact teeth. In Groups 2-8, root canal treatme...
