PURPOSE Our aim was to determine the precision of MR imaging evaluation of perineural spread of head and neck tumors. METHODS Nineteen patients had complete extirpation of head and neck tumors (10 squamous cell carcinomas, four adenoid cystic carcinomas, one poorly differentiated carcinoma, one salivary duct carcinoma, one mucoepidermoid carcinoma, one(More)
Introduction Impact of treatment and prognostic indicators of outcome are relatively ill-defined in esthesioneuroblastomas (ENB) because of the rarity of these tumors. This study was undertaken to assess the impact of craniofacial resection (CFR) on outcome of ENB. Patients and Methods Data on 151 patients who underwent CFR for ENB were collected from 17(More)
Maxillary osteotomies are done to correct discrepancies in structural facial harmony. The deformities involve retrusion or protrusion, as well as pathological shortening and elongation of the maxilla. Surgical orthopedics of the maxilla move the nose in part, or in whole, in relationship to the rest of the face. Corrective rhinoplasty is sometimes necessary(More)
Adult rats fed high concentrations of dietary protein for 9 weeks gained more weight than rats fed isoenergetic diets containing less protein. There were no significant differences in tail and body lengths among several groups of rats on diets containing different amounts of protein; however, total body fat was significantly greater in the rats fed on diets(More)
Much of craniofacial trauma involves the frontal sinuses. Because of its response to injury, the frontal sinus mucosa has an innate ability to develop mucoceles, and if infected, mucopyocoeles. This article presents a therapeutic algorithm for all forms of craniofacial trauma with concentration on the most severe injury-the through and through fracture and(More)
Objectives To evaluate angiographic patterns that may predict the success or failure of carotid artery balloon test occlusion (BTO) and single-photon emission computed tomography (SPECT) analysis for carotid sacrifice. Study Design This is a retrospective nonrandomized study. Study Setting Conducted at the University of California Davis Medical Center,(More)
PURPOSE The objective of this study is to determine the prevalence of tobacco consumption (i.e., cigarette use) among survivors of head and neck cancer after treatment with radiation therapy (RT). METHODS AND MATERIALS A longitudinal study was conducted with 230 patients previously treated with RT for squamous cell carcinoma of the head and neck. All(More)
PURPOSE To determine whether plain film and CT findings help predict the presence and severity of vascular trauma. METHODS The records of 65 patients with gunshot wounds of the neck were reviewed. There were 58 men and 7 women ranging in age from 2 to 72 years. All had angiography of the cervical vessels; in addition, 64 had plain radiography, 22 had CT,(More)
