Influence of the Furlow Palatoplasty for Patients With Submucous Cleft Palate on Facial Growth

The purpose of this study was to investigate the facial growth in patients with submucous cleft palate operated on using the Furlow palatoplasty. A total of 30 patients with submucous cleft palate underwent Furlow palatoplasty from 1993 to 1998. The mean follow-up period was 4 years and 3 months. Twenty-five of 30 patients were followed up. Mid-facial growth was measured using lateral cephalograms in 18 patients whose age was greater than 8 years. The parameters obtained in the lateral cephalogram were compared with those of a healthy population in Korea. Eleven (61.1%) of 18 patients observed were within the clinical normal range for the age group for the parameter of the span between the anterior nasal spine and posterior nasal spine, 6 patients (33.3%) were over the range, and 1 patient (5.6%) was below the range. For the sella-nasion-subspinale angle, 55.6% of patients were within the clinical normal range, 27.8% were over the range, and 16.6% were below the range. For the sella-nasion-supramentale angle, 55.6% of patients were within the clinical normal range, 22.2% were over the range, and 22.2% were below the range. For the sella-nasion-subspinale-sella-nasion-supramentale angle, 72.2% of patients were within the clinical normal range, 27.8% were over the range, and none were below the range. For the span between the basion and posterior nasal spine, 50.0% of patients were within the clinical normal range, 27.8% were over the range, and 22.2% were below the range. In conclusion, our results suggest that the Furlow palatoplasty is a useful procedure as an initial treatment of submucous cleft palate and that this technique has a less harmful effect on facial growth because there is no excessive surgical intervention on the hard palate and alveolar process.
