The incidence of velopharyngeal insufficiency and oronasal fistula after primary palatal surgery with Sommerlad intravelar veloplasty: A retrospective study in Isfahan Cleft Care Team.

Objectives: This study was designed to determine the incidence of velopharyngeal insufficiency (VPI), oronasal fistula development and facial grimace in patients seen by Isfahan Cleft Care Team (ICCT) after primary Sommerlad intravelar veloplasty (SIVV). Furthermore the association of gender, cleft type and age at primary surgery with the incidence of hypernasality and fistula is determined.

Methods: A group of 40 patients with history of cleft palate with or without cleft lip were identified from the records of ICCT between 2011 and 2014.

Automatic identification of hypernasality in normal and cleft lip and palate patients with acoustic analysis of speech.

Hypernasality is seen in cleft lip and palate patients who had undergone repair surgery as a consequence of velopharyngeal insufficiency. Hypernasality has been studied by evaluation of perturbation, noise measures, and cepstral analysis of speech. In this study, feature extraction and analysis were performed during running speech using six different sentences.
