BACKGROUND: Patients who present for a trauma workup often have a head computed tomography (CT) performed to identify intracranial pathology. Facial fractures are routinely identified in these patients, and further imaging is the norm with dedicated facial CT scans. Additional imaging increases radiation doses; however, it is unclear if additional operative fractures are identified. The aim of this study was to examine differences between these 2 CT imaging modalities. METHODS: A retrospective review of all operative facial trauma patients receiving both head and facial scans at a single institution was performed (1999-2012)...

BACKGROUND: Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal. Preoperative presumptive diagnosis is performed by means of radiography using orthopantomographs, computerized tomographs, or cone beam scans. Treatment is surgical and consists of careful exeresis and curettage of the adjacent tissue. In recent years, piezoelectric surgery has been used to treat bone pathologies in the maxillofacial area, orthopedic surgery, and neurosurgery...

A 30-year-old female patient with facial pain diagnosed as organizing hematoma of maxillary sinus by biopsy and imaging studies, and subsequently tumor was resected via an endoscope-assisted midfacial degloving approach. The tumor was histopathologically confirmed as organizing hematoma. In 3-week follow-up, asymptomatic emerging mass was observed at the same site, and needed a revision endoscopic resection. On pathologic examination, a low-grade angiosarcoma was identified, not organizing hematoma. After postoperative radiotherapy, she has been a status of no evidence of disease...

Moebius syndrome, also called congenital facial paralysis is a rare neurological disease, whose etiology is not fully elucidated. It affects especially facial and oculomotor cranial nerves and its clinical feature is peripheral facial paralysis. The objective of the study is to highlight the anatomical and functional changes in the Moebius syndrome and establish certain criteria that should be the basis for reparative surgery in this disease. For this purpose, we used a group of six patients diagnosed with this pathology, in whom we pursued functional anatomical and histological changes of the superficial layers of the face that we have grouped in terms of their clinical impact...

BACKGROUND: The surgical management of benign parotid tumors is aimed at complete extirpation of the mass with preservation of facial nerve function. There is a relative paucity of literature pertaining to complications after benign parotid surgery and related risk factors. We aim to critically review the outcomes following treatment of benign parotid pathology when surgery entailed either complete superficial parotidectomy (CSP), partial superficial parotidectomy (PSP) or extracapsular dissection (ECD)...

BACKGROUND: Arteriovenous fistula (AVF) is defined as an abnormal communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels and the near draining veins without normal intervening capillary bed. Arteriovenous fistula incurs in preauricular region is exceeding rare. Most of these fistulae occur as a result of an iatrogenic injury, the volume is small, feeding and draining vessels of feeding and draining are simple, and can be cured easily...

Importance: The nasal base view is often overlooked in rhinoplasty analysis and, unlike lateral and frontal views, lacks detailed quantitative analysis and descriptors. While shape-category analysis of the nasal base is well established, these descriptive methods remain subjective and do not facilitate quantitative analysis. Objective: To establish a simple and quantitative classification scheme using a multiple-parameter numerical model for analyzing and describing the shape of the nasal base...
