Relationship of Velopharyngeal Insufficiency With Face Mask Therapy in Patients With Cleft Lip and Palate.

OBJECTIVE

To determine whether orthodontic/dentofacial orthopedic maxillary protraction face mask therapy induces changes in velopharyngeal functioning in a cohort of pediatric patients having cleft palate with or without cleft lip.

DESIGN

Retrospective chart review.

SETTING

A children's hospital in the United States.

PARTICIPANTS

Forty-three pediatric patients with cleft palate, with or without cleft lip, syndromic or with isolated clefts, who received face mask therapy from January 2009 to April 2016.

INTERVENTION

Clinical data were extracted for review and analysis from medical records obtained from the Cleft Database/Research Registry (CDB-RR).

MAIN OUTCOME MEASURES

Pittsburgh Weighted Speech Scores (PWSS) before and after therapy.

RESULTS

There was a significant increase in PWSS after face mask therapy for patients with a PWSS score of 0 prior to treatment. Patients with PWSS >0 before treatment remained largely stable after face mask therapy. Maxillary advancement was not significantly associated with change in PWSS or fistula presence/absence.

CONCLUSIONS

There is an increased risk of velopharyngeal insufficiency with maxillary protraction face mask treatment in patients with cleft palate. Patient counseling and obtaining consent regarding speech changes during treatment are recommended.
