The Association of Oto-rhino-laryngology and Maxillo-facial Surgery of Quebec provides this definition of an ENT specialist:
We may diagnose all conditions pertaining to the ears, the nose, the throat, the neck, and we can offer medical or surgical treatment, as necessary. With specialized medical training, the ENT specialist is the best professional to diagnose and treat cancers of the superior aerodigestive tracts (nose, mouth, pharynx and larynx).
The Order of ortophonists and audiologists of Quebec provides this definition of an audiologist :
The audiologist is the professional that prevents, evaluates and treats hearing troubles (i.e. hearing loss, tinnitus) and vestibular system troubles (i.e. vertigo). The audiologist focuses on the harm caused to hearing and health by noise, especially in cases of professional deafness caused by long-term exposure to noise in a work environment and to increasingly common deafnesses linked to recreational habits and prolonged music playback.
The audiologist evaluates the needs of a person in several situations (in school, at home, at work, in social activities) in order to provide adapted and complete services which will improve the person's ability to communicate, improve his or her autonomy and improve his or her integration.
