Sound-induced stapes velocity (Vs) was measured intraoperatively in 14 patients undergoing cochlear implantation. All 14 patients had no history of middle-ear pathology, and their ossicular chains appeared normal on intraoperative inspection and palpation. The magnitude of the mean Vs (normalized by simultaneously-measured ear-canal sound pressure) was(More)
There are many known causes of vertigo, but many cases remain unexplained. Sound-induced, pressure-induced, or positional vertigo caused by bony dehiscence of the superior semicircular canal into the middle cranial fossa is a newly described etiology of vertigo. Three case studies of patients with CT evidence and surgical confirmation of bony dehiscence of(More)
Gastroesophageal reflux disease (GERD) is the abnormal retrograde flow of gastric contents into the esophagus. While disorders of the esophagus related to GERD are fairly well characterized, supraesophageal symptoms may be nonspecific and easily missed. Fewer than half of the patients with otolaryngologic complications of reflux exhibit the classic findings(More)
The purinergic regulation of ciliary activity was studied using small, continuously superfused explants of human nasal epithelium. The P2Y(2) purinoceptor (P2Y(2)-R) was identified as the major purinoceptor regulating ciliary beat frequency (CBF); UTP (EC(50) = 4.7 microM), ATP, and adenosine-5'-O-(3-thiotriphosphate) elicited similar maximal responses,(More)
OBJECTIVES This study was designed to compare the incidence and nature of facial nerve stimulation (FNS) in patients receiving cochlear implants (CI) manufactured by Cochlear Corporation, Advanced Bionics Corporation, and MedEl. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS The charts of 600 patients who received CIs(More)
OBJECTIVE To evaluate the penetration of ototopicals and water through tympanostomy tubes (TT) using a physical model. STUDY DESIGN An in vitro model was created to measure the ability of various solutions to penetrate a variety of TT. METHODS A TT was placed through a perforation (myringotomy) in a silastic sheet (tympanic membrane) fixed between the(More)
Neck dissection is a surgical procedure used in the diagnosis and treatment of head and neck cancer. The neck dissection involves excising the lymph nodes in specified regions of the neck with or without removing the sternocleidomastoid muscle, the internal jugular vein, and the spinal accessory nerve. The removal of cervical lymph nodes not only aids in(More)
Sinonasal undifferentiated carcinoma is a relatively rare and aggressive malignancy of the nose and paranasal sinuses. It is often difficult to distinguish from other poorly differentiated sinonasal malignancies. Since it was first described in 1986, advances have been made in the understanding of the histology and immunohistochemical markers of sinonasal(More)
