A child with cranio-carpo-tarsal dysplasia or whistling face syndrome is described together with a new surgical procedure for the correction of the mouth deformity. The syndrome is rare; only approximately 40 cases have been described in the literature since 1938. Correction of the facial appearance is of great importance to the affected individuals because of emotional problems they may develop as a reaction of their anomalies. Although the majority of cases have been sporadic, the syndrome can be transmitted as an autosomal dominant trait. Therefore, genetic counseling for affected persons should be offered.
