title: Morphology of isolated cleft palate in children, including Robin sequence, treated with one or two-stage operations.
abstract: A classification developed at the Uppsala Cleft Palate Centre was used to describe isolated cleft palate in children with and without Robin sequence. The study included 109 patients born between 1968 and 1983 with isolated cleft palate. In 46 patients the cleft was closed in a single operation and 63 were treated by a two-stage procedure. Of the 109 patients 70 (64%) were girls. In 19 patients (17%), the cleft was limited to the soft palate. Ninety of the patients had clefts of the hard palate and in 39 (43%) of these patients the clefts involved less than a third of the hard palate. Only four children (4%) had total clefts of both the hard and soft palate. The Robin sequence was diagnosed in 14 children (13%), and it was more common in boys with isolated cleft palate (7/39; 18%) than in girls (7/70; 10%). In those with Robin sequence the cleft was U-shaped anteriorly in nine (64%), with great variations in width. Generally, however, the clefts were wider than other clefts involving the hard palate. In all cases, closure of the soft palate was followed by a spontaneous reduction in the width of the remaining cleft in the hard palate. The greatest improvement was noted in subjects with the U-shaped clefts, in whom the position of the tongue probably had the greatest influence on the development of wide primary clefts. In 10 subjects with clefts of the soft palate only and 12 patients in whom the cleft included part of the hard palate (35%), only the first operation of the two-stage procedure was done because there was no residual cleft. In these subjects the original cleft had involved less than a third of the length of the hard palate.
