  Purpose
Compare the outcome of two primary surgeries techniques (von Langenbeck and Furlow double z-plasty) performed on children with cleft lip/palate to determine if one results in significantly better velopharyngeal competency for speech.

Condition Intervention Phase
Cleft Lip Cleft Palate Procedure: Furlow double z-plasty palatoplasty palate repair Procedure: Von Langenbeck palatoplasty palate repair Phase 2

Study Type: Interventional

Primary Outcome Measures:
  • Velopharyngeal function for speech was identified to be better for patients who received the Furlow double opposing z-palatoplasty procedure than patients who received the von Langenbeck procedure, as determined by the Cul-de-Sac Test of Hypernasality. [ Time Frame: 6 months ]

Enrollment: 475
Study Start Date: February 1996
Study Completion Date: April 2007
Primary Completion Date: March 2006 (Final data collection date for primary outcome measure)
Detailed Description:
This study is conducted with patients with complete unilateral cleft lip and palate. The subjects will have their palatal clefts surgically repaired by either the von Langenbeck or the Furlow double z-plasty palatoplasty. Patients will be randomly assigned to four groups, to have with the von Langenbeck palatoplasty with intravelar veloplasty or the Furlow double opposing z-plasty palatoplasty between 9 and 12 months of age or between 15 and 18 months of age. Lip repair will be randomized to either the Spina or Millard method and will be accomplished by six months prior to palatoplasty. The major emphasis will focus on assessment of the near and long term outcomes of the palatal surgeries on velopharyngeal function for speech.
