Research Facilities at the UW Health Sciences Building

  • Laryngeal Physiology Laboratory
  • Auditory and Vestibular Laboratories
  • Temporal Bone/Microvascular Laboratory
  • Location
  • Library/Resident Workroom
  • Computer facilities

Laryngeal Physiology Laboratory:

The fully equipped clinical laryngeal laboratory includes stroboscopy with photographic flexible and rigid telescopes, and recording/editing equipment in Betacam, 3/4", or VHS formats. Aerodynamic measurements, computer assisted subglottic pressure recordings, and electroglottography are used to study individual patients. Electromyography, both needle and indwelling multi-channel fine wire, are routinely employed to study patients with neurolaryngeal disorders such as paralysis, dystonia, and other central neurologic disorders.

The laryngeal disorders program has a full time speech pathologist and includes consultants in gastroenterology, esophageal surgery, pulmonary medicine, and electrodiagnostics in rehabilitation. The Neuromuscular Clinic for Speech and Swallowing Disorders is entering its eleventh year. All aspects of neurologic speech and swallowing abnormalities are studied and managed. The clinic treats patients disorders such as Parkinson's Disease, multiple sclerosis, stroke, psychogenic, and congenital disorders. A particular focus of the clinic has been amyotrophic lateral sclerosis, with over 200 patients. Research efforts have included publication of assessment scales and management techniques as well as participation in clinical drug trials.


Auditory and Vestibular Laboratories:

This 1500 square feet facility contains 3 examination rooms, 4 audiometry booths, an ENG laboratory, and a vestibular testing room with a rotating chair, posturography platform, and search coil technology.

The otologic examination rooms contain binocular microscopes with video monitors for standard otomicroscopy plus middle ear endoscopy equipment. A minor surgery facility is available as well as two otomicroscopy rooms for minor procedures.

In the audiometry section, equipment and personnel are available to perform standard clinical hearing threshold testing and tympanometry, plus auditory brainstem response audiometry, electrocochleography, distortion product otoacoustic emission audiometry, real-ear measures of amplification performance, and free field hearing testing for infants and adults. The audiology section is fully computerized - all clinical data is managed directly by a database system developed in our department. This fully relational database automatically stores every audiogram done in our clinic. There is an active cochlear implant program as well as the full range of diagnostic and rehabilitative services.

The two vestibular test rooms provide standard electronystagmographic testing, posturography, and sinusoidal rotational chair testing. The new search coil technology permits the 3-D analysis of eye movements induced by rapid angular vestibular stimulation, sound pressure, and low-velocity rotation.


Temporal bone/Microvascular laboratory:

A modern temporal bone/microvascular dissection laboratory has just been completed. This state of the art facility includes 5 microscopic dissection stations. One station is equipped for teaching with a video camera connected to video monitors in the lab and the departmental library.



The research facilities on the 11th floor of the Health Sciences Building previously occupied by the auditory and vestibular basic science group (now located at the Bloedel Research Center) are presently being remodeled. Nearly 1000 square feet of lab and office space is projected for the recruit of another investigator in molecular biology. A separate space is being remodeled to house computers, a data manager and a programmer dedicated to clinical outcomes research.


Library and Resident Workroom:

The library is equipped with state of the art video and CD equipment and a generous supply of educational materials (texts, teaching tapes and CD ROM). It is directly linked to the video system in the temporal bone teaching lab, and also serves as a convenient conference center.

The dedicated offices for residents and fellows have separate carrels, each with a dedicated computer fully integrated into the university network.


Computer Facilities:

Each of the laboratories has extensive computer facilities for on-line experimental control, data analysis and graphics production. In addition, the department is equipped for interactive outcomes studies and interlaboratory communication. This system is based on DEC 5023 hardware and is designed for multiple users with dial-in capabilities via Macintosh or IBM based systems. The department also has extensive image analysis equipment for in vitro imaging of tissue and organ cultures and for morphometric analysis of microscopic tissue samples.
