Risk Assessment of Sleep Disordered Breathing in Cleft Lip and/or Palate

Abstract

Objective

Children with cleft lip and/or palate (CL/P) are at increased risk for Sleep Disordered Breathing (SDB), particularly Obstructive Sleep Apnea (OSA). At our institution, routine screening for SDB is performed using the Chevrin Pediatric Sleep Questionnaire (PSQ). This analysis is a practice audit looking at the outcomes of screening children with CL/P.

Design/Setting/Patients/Participants

A single-center, retrospective analysis was done of all non-syndromic patients with CL/P over the age of 36 months over a 4-year period. Children with known OSA were eliminated from analysis.

Main Outcome Measures

Univariate logistic regression was used to assess predictors for SDB (PSQ score > 8) amongst various patient, disease, and treatment characteristics. Outcomes of those screened were tracked.

Results

Of the 239 patients in the study cohort, 43 (18%) had positive PSQs. These subjects were more likely to have class III dental occlusion with maxillary retrusion (OR = 2.65, 95% CI: 1.2–5.8, p = 0.02). There were no differences amongst age, type of cleft, Veau classification, BMI, or history of pharyngeal surgery. One third of the group did not complete recommended testing. Twenty-five subjects with positive sleep screening underwent subsequent polysomnography and 21 (84%) had OSA.

Conclusion

Routine screening reveals a significant proportion of patients with CL/P with symptoms suggestive of OSA. While several patients did not complete confirmatory testing, those who completed a PSG had a high rate of identification of OSA. After excluding children with known OSA, patients with SDB are also likely to have class III dental occlusion and maxillary retrusion.
