One of the primary goal of cleft palate repair is to provide an intact mechanism for normal speech production. The purpose of this study is to evaluate the two-flap mucoperiosteal palatoplasty procedure on speech outcomes in patients undergoing surgical repair before the age of 2 years. A retrospective analysis study was done on 22 children with complete unilateral cleft palate (with or without cleft lip) who underwent two-flap palatoplasty between year 2002 to 2006 at Cipto Mangunkusumo Hospital. Evaluation was performed by a speech pathologist for pattern of articulation, hypernasality, intelligibility, and velopharyngeal competence. Palatoplasty were performed after 2 year-old in 11 patients and before 2 year-old in 11 patients. Speech of the 22 children postpalatoplasty was evaluated perceptually from standardised tape recordings. Velopharyngeal competence in patients who underwent palatoplasty before 2 year-old compared to after 2 year-old were 72.7% good, 18.2% fair and 9.1% poor versus 54,5% good, 9,1% fair and 36,4% poor respectively. Two-flaps mucoperiosteal palatoplasty performed before the age of 2 years old shows better spepolech outcome in all parameters, although the numbers are not statistically significant. Further prospective study with larger sample is needed.
