The importance of neurology and genetic testing in the patient with non-cleft velopharyngeal dysfunction.

Objective: A significant proportion of the referrals made to a speech investigation clinic in a cleft unit include patients with non-cleft velopharyngeal dysfunction (VPD). This study aims to quantify the underlying diagnoses of these patients and describe the investigative pathway and diagnostic information subsequent to presentation in our clinic.

Materials And Methods: The case notes of 136 consecutive patients with non-cleft VPD who attended our Velopharyngeal Investigation (VPI) clinic from July 2014-December 2019 were reviewed.
