OBJECTIVE To characterize the clinicopathologic features of head and neck follicular dendritic cell (FDC) tumor and report the experience of this entity at our institution. STUDY DESIGN Two case presentations are compared with a retrospective analysis of all published head and neck cases. SETTING A tertiary academic medical center. RESULTS Thirty four(More)
Two human cell lines were established from untreated squamous cell carcinomas of the head and neck. Line 183 was derived from a head and neck squamous cell carcinoma of the tonsil and 1483 from a head and neck squamous cell carcinoma of the retromolar trigone. Both lines grow in a cobblestone pattern demonstrating their epithelial heritage.(More)
DC00166e and acute unilateral deafferentation of the auditory periphery (auditory and vestibular afferents) can induce changes in the central nervous system that may result in unique forms of tinnitus. These tinnitus perceptions can be controlled (turned on and off) or modulated (changed in pitch or loudness) by performing certain overt behaviors in other(More)
The efficacy and safety of cefixime, the first oral third-generation cephalosporin, were evaluated in a multicenter clinical trial involving 118 adult patients with acute sinusitis or acute exacerbations of chronic sinusitis. Patients received a single daily dose of 400 mg of cefixime for a mean duration of 10 days; 106 patients completed a course of(More)
Forty -seven of 79 patients with sinus and paranasal tumors had clinical, radiographic or operative evidence of orbital involvement. Seventy percent of those patients with orbital extension had clinical or radiographic involvement of the orbit at the time of initial presentation. Common presenting signs and symptoms included proptosis, nasal obstruction or(More)
A unique and intriguing form of subjective tinnitus evoked by eye gaze is reviewed. A new perspective is presented because this condition is sufficiently different from other forms of subjective tinnitus and its manifestation cannot be adequately explained by existing models or conceptual frameworks. Our examination of this topic considers pathophysiologic(More)
Laryngoscopy and panendoscopy can cause airway complications. To determine the risk to the airway from reintubation following general anesthesia in otolaryngology patients, we examined recovery room and anesthesia records at the Albany Veterans Administration Medical Center covering a 10-year period. From this information we determined the incidence of(More)
Auditory perceptual and visual-spatial characteristics of subjective tinnitus evoked by eye gaze were studied in two adult human subjects. This uncommon form of tinnitus occurred approximately 4-6 weeks following neurosurgery for gross total excision of space-occupying lesions of the cerebellopontine angle and hearing was lost in the operated ear. In both(More)
OBJECTIVE To determine whether 3 Tesla (T) magnetic resonance imaging (MRI) with delayed contrast imaging has sufficient anatomic resolution to image the intracochlear fluid spaces (i.e., the scala tympani, scala media, and scala vestibuli) of the inner ear and identify endolymphatic hydrops in vivo. STUDY DESIGN Four normal subjects underwent 3T MRI(More)
BACKGROUND The aim of this study was to determine the incidence and perioperative management of patients with cerebrospinal fluid (CSF) fistulas during endoscopic sinus surgery (ESS) in New York State. METHODS A questionnaire was mailed to otolaryngologists in New York State who were registered with the American Academy of Otolaryngology, Head and Neck(More)
