OBJECTIVE To describe the clinical features, causes, imaging characteristics, treatment, and outcome of patients with the acquired immunodeficiency syndrome (AIDS) and sino-orbital aspergillosis. DESIGN Records of 5 patients were reviewed. Results of imaging and histopathologic examinations and clinical courses of the patients were studied. RESULTS(More)
OBJECTIVE There is ongoing debate on the pathogenic mechanisms of cholesterol granuloma formation in the temporal bone. The purpose of this report is to provide evidence in support of the exposed marrow hypothesis in explaining the pathogenesis of petrous apex cholesterol granuloma. STUDY DESIGN Retrospective single case study. MAIN OUTCOME MEASUREMENT(More)
OBJECTIVE/HYPOTHESIS Craniofacial resection (CFR) represents the traditional approach for resection of anterior skull base (ASB) malignancies. However, this past decade has witnessed the emergence of transnasal endoscopic ASB resection (TER) as a feasible alternative. The aim of this study was to compare TER and CFR for ASB malignancy resection. METHODS(More)
BACKGROUND The olfactory epithelium is a self-renewing tissue, able to produce new neurons as needed from stem and progenitor cells in its basal layers. In addition, there exists a mesenchymal-like stem cell (MSC) located within the underlying lamina propria. Little is known about the function of this nasal MSC, or its relationship to the olfactory lineage,(More)
Electrical stimulation of the vagus nerve has shown efficacy in controlling seizures in experimental models, and early clinical trials have suggested possible benefit in humans. Eleven patients with complex partial seizures were subjected to implantation of vagus nerve stimulators. Electrode contacts embedded in silicone rubber spirals were placed on the(More)
OBJECTIVES To determine the necessity for lumbar drains during endoscopic cerebrospinal fluid (CSF) rhinorrhea repair. METHODS Thirty-three patients underwent endoscopic repair of CSF rhinorrhea without a lumbar drain during a 7-year period. The size of the dural defect ranged from a microleak (less than 1 mm dural defect) to a 3-cm dural defect of the(More)
OBJECTIVES The differential diagnosis and treatment of patients with chronic cough, paradoxical vocal fold motion, and disordered breathing can be a challenge to most practicing otolaryngologists. Tracheobronchial (ie, asthma, bronchitis, and tracheal stenosis), laryngeal (ie, vocal fold paralysis and neoplasms), and rhinologic (ie, allergies and(More)
This article discusses the development and anatomy of the nasal septum and structures of the lateral nasal wall. Emphasis is placed on anatomic variations associated with surgically correctable nasal obstruction. Common variations, such as deviated nasal septum, inferior turbinate hypertrophy, paradoxic middle turbinate, and concha bullosa, are discussed.(More)
Esthesioneuroblastoma (olfactory neuroblastoma) is a rare malignant neoplasm originating from neuroepithelial cells. Treatment for this tumor has traditionally required a craniofacial resection through an external approach. The safety and efficacy of transnasal endoscopic resection is uknown. A series of five patients with Kadish stage A or B lesions of the(More)
