title: Effect of Veau-Wardill-Kilner type of cleft palate repair on long-term midfacial growth.
abstract: There is a common concern that the Veau-Wardill-Kilner type of cleft palate repair causes extensive denudation of the palate, resulting in inhibition of maxillary growth. The evidence for this belief is equivocal in the literature. The authors present some long-term results of this technique from a pure sample of nonsyndromic complete unilateral cleft lip and palate patients operated on by a single intermediate-volume cleft surgeon over a period of 25 years. Twenty-five patients, all born between 1977 and 1989, met the above inclusion criteria. Their age at the time of collection of study models and cephalograms was 9 to 17 years (average, 12 years). Midfacial growth was studied using 12-year dental models and lateral cephalograms taken before definitive orthodontic treatment. These were evaluated using the GOSLON Yardstick and digital cephalometric analysis. The final GOSLON results show that 72 percent of the patients had a good or satisfactory outcome, with a GOSLON score of 1, 2, or 3, and only 28 percent ended with a poor score of 4 or 5. The poor sensitivity of cephalometrics in discerning statistically significant differences was highlighted by the huge overlaps observed in the 95 percent confidence interval graph of mean sella-nasion-subspinale angle (S-N-A) values when comparing the results of the Eurocleft centers with those of the authors' center. The results suggest that satisfactory long-term midfacial growth can be obtained with Veau-Wardill-Kilner cleft palate repair.
