title: Evaluation of a surgical technique for trigonocephaly.
abstract: Clinically diagnosed trigonocephaly have been treated by a standard surgical technique developed at Göteborg University Craniofacial Unit. To evaluate the technique we designed a study to include both subjective and objective assessments. Of 30 patients operated on between 1988-1997, 15 patients with at least three years postoperative follow-up have been included. An evaluation of the surgical outcome of the bitemporal width, the forehead contour, and the intercanthal distance was made both subjectively using a visual analogue scale (VAS) and objectively with analyses of cephalograms taken preoperatively and postoperatively at 3 and 5 years of age. For the subjective evaluation a control group of 10 randomly selected children from a Child Welfare Centre were selected. For the objective evaluation the control group consisted of cephalograms from children born with cleft lip and palate who were matched regarding sex and age. Both cephalometric analysis and subjective studies of the outcome indicated improvement. When the forehead contour was investigated the number of patients who had been improved or corrected completely was higher when evaluated subjectively. When interorbital distance on cephalograms and intercanthal distance scores on VAS were evaluated, again the subjective study indicated improvement in more subjects.
