    Abstract:
    X-ray cephalometry was used for the assessment of the configuration of the skeletal and soft tissue profile in 81 adult males with isolated cleft palate. They were assessed in three subgroups, i. e. with complete and incomplete clefts and with clefts of the soft palate alone and were compared with a matched group of controls consisting of 50 normal males, as well as with the situation in the earlier examined series with unilateral cleft lip and palate. In isolated cleft palate both the upper and lower jaws were retruded. The maxilla was most markedly retruded in incomplete clefts and most slightly in clefts of the soft palate alone, while the mandible showed the smallest degree of retrusion in complete clefts. The configuration of the skeletal profile was similar as in unilateral cleft lip and palate, yet positive overjet was on the average restored in all types of isolated cleft palate. A more favourable configuration of the profile was present in patients with cleft soft palate alone, in the absence of an impairment of sagittal jaw relations. Changes in the configuration of the soft profile were due mainly to skeletal deviations. The retrusion of skeletal framework of the middle face was to a large degree masked by the larger thickness of the upper lip, in complete clefts also of the lower lip. Therefore the prominence of the upper lip was only slightly impaired and slight flattening of the face occurred only in complete clefts. The more horizontal slope of the columella resulted in a reduction of the nasolabial angle. Some deviations from the described pattern occurred in clefts of the soft palate alone (steeper slope of the upper lip with an unchanged nasolabial angle, normal thickness of the upper lip a. o.). The findings are suggestive of a differing facial physiognomy in isolated cleft palate.
