The laboratory is situated at the Montreal Children's Hospital, B-240 (Departmental Clinic). The research deals with pediatric voice and speech problems. This computer-based laboratory is the only pediatric facility in Canada. Equipment includes CSL (Computerized Speech Lab) with its various components: MDVP (Multi-Dimensional Voice Program) and nasometer.

The different types of voice pathology are studied and include:

  • vocal cord nodules and polyps
  • vocal cord paralysis
  • subglottic and glottic stenosis
  • all other congenital and acquired laryngeal problems

Patients with speech defects also benefit from the expertise of the lab. Defects include:

  • velopharyngeal insufficiency
  • cleft palate (including submucous clefts)
  • hyponasality
  • hypernasality

The clinical work is shared by otolaryngologists (fellows, residents, medical students, and staff) and speech therapists, and the patient data base covers the province of Quebec, the Maritime provinces, and various New England states. Different speech pathologists, otolaryngologists, plastic surgeons, gastroenterologists, and respirologists refer their patients to the laboratory.
