Abstract
The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI) is
an alternative treatment for patients with conditions that preclude surgery and for
those individuals with a hypofunctional velopharynx (HV) with a poor prognosis for
the surgical repair of VPI. Understanding the role and measuring the outcome of
prosthetic treatment of velopharyngeal dysfunction requires the use of tools that
allow for documenting pre- and post-treatment outcomes. Experimental openings in
speech bulbs have been used for simulating VPI in studies documenting changes in
aerodynamic, acoustic and kinematics aspects of speech associated with the use of
palatal prosthetic devices. The use of nasometry to document changes in speech
associated with experimental openings in speech bulbs, however, has not been
described in the literature.
