Comparison of the rate of palatal fistulation after two-flap and four-flap palatoplasty.

We studied 73 repairs of cleft palate (48 cleft lip and palate and 25 isolated cleft palate) done during a 7-year period (January 1996-October 2002) by the same plastic reconstructive surgeon. Two-flap or four-flap palatoplasty techniques were used to provide tension-free, three-layer repairs for patients with cleft palate. Their ages ranged from 10-244 months (mean 27). The postoperative follow-up period ranged from 6 to 60 months (mean 21). There was a palatal fistulation rate of 7% (5/73). There were two fistulas after two-flap palatoplasty (5%, 2/39), and three fistulas after four-flap palatoplasty (9%, 3/34). The mean diameter was 7.8 mm (range 5.1 to 13). There was no significant difference between the two techniques.
