Anatomic Severity, Midfacial Growth, and Speech Outcomes in Van der Woude/Popliteal Pterygium Syndromes Compared to Nonsyndromic Cleft Lip/Palate.

OBJECTIVE: To summarize the clinical characteristics and surgical and speech outcomes for patients with Van der Woude/popliteal pterygium syndromes (VWS/PPS) and to compare them with a historic cohort of patients with nonsyndromic cleft lip/cleft palate (CL/P). DESIGN: Retrospective chart review. SETTING: Tertiary care center. PATIENTS: All patients with VWS/PPS seen at Boston Children's Hospital from 1979 to 2012: 28 patients with VWS (n = 21)/PPS (n = 7) whose mean age was 17.3 +/- 10.4 years, including 18 females (64%) and 10 males (36%); 18 patients (64%) had a family history of VWS/PPS. MAIN OUTCOME MEASURES: Cleft type, operative procedures, speech, and midfacial growth. Data were compared with historic cohorts of patients with nonsyndromic CL/P treated at one tertiary care center. RESULTS: There were 24 patients (86%) with CP+/-L, Veau types I (n = 4, 17%), II (n = 4, 17%), III (n = 5, 21%), and IV (n = 11, 46%). Nine patients (38%) had palatal fistula after palatoplasty. Fourteen of 23 (61%) patients with CL/P age 5 years or older had midfacial retrusion, and 10 (43%) required a pharyngeal flap for velopharyngeal insufficiency. Fisher's exact test demonstrated higher frequencies of Veau type IV CP+/-L (P = .0016), bilateral CL+/-P (P = .0001), and complete CL+/-P (P < .0001) in VWS/PPS compared with nonsyndromic patients. Incidences of midfacial retrusion (P = .0001), palatal fistula (P < .0001), and need for pharyngeal flap (P = .0014) were significantly greater in patients with VWS/PPS. CONCLUSIONS: Patients with VWS/PPS have more severe forms of labiopalatal clefting and higher incidences of midfacial retrusion, palatal fistula, and velopharyngeal insufficiency following primary repair as compared with nonsyndromic CL/P.
