Vocal Cord Description of A Patient with Paradoxical Vocal Cord Dysfunction:
According to Brugman and Simons (1998), there are three main configurations of the vocal cords if a patient has vocal cord dysfunction.
1. Complete Closure - This can be a complete
closure in the expiratory or
inspiratory phase of
respiration. (Closing during experation can also
be a symptom of asthma.)
2. Chinking - "is the result of adduction of
the anterior two-thirds of
the vocal cords, by which
a posterior diamond-shaped opening is
formed (p. 65).
3. Periglottic tissue prolapse - this involves
a prolapse of all or some of the
periglottic tissues through
the glottic opening during inspiration.
Normal vocal cords allow air to pass through freely at mid-inspiration (Brugman & Simons, 1998).
