title: Configuration of facial profile in adults with cleft lip with or without cleft palate.
abstract: X-ray cephalometric studies were carried out in 114 adult males with cleft lip and with or without cleft palate. According to the type and extent of the cleft they were subdivided into 4 groups and were compared with a control group of 50 normal males matched in age. Investigated were the parameters of the skeletal and soft facial profile. The results showed that cleft lip alone is associated with deviations of local character concerning only soft tissues within the oronasal region. The ascertained deviations included a flattening of the nose, reduction of the height, concavity and prominence of the upper lip, increased height of the upper lip vermilion and a more horizontal slope of the columella leading to a reduction of the nasolabial angle. Cleft lip and palate was associated with deviations of global character related predominantly to the extent of retrusion of the upper and lower jaw. The skeletal profile was altered and its deviations were reflected by changes of the soft profile. Of the deviations of soft tissues per se were most important the flattening of the nose and reduction of the height and thickness of the upper lip, which underlined the presence of retrocheilia. Maxillary retrusion was more marked in complete than in incomplete unilateral clefts, while mandibular retrusion and maxillary dentoalveolar retroinclination were more marked in bilateral than in unilateral clefts. Occlusion was always impaired. In unilateral involvement, especially in complete clefts the more horizontal slope of the columella resulted in a marked reduction of the nasolabial angle. Incomplete clefts, similarly as cleft lip alone were not associated with a reduction of thickness of the upper lip and showed an increase of the vermilion height. Because of the persisting protrusion of the premaxilla bilateral clefts were accompanied by only a slight flattening of the skeletal profile and by an excessive nasal depth after the prolongation of the columella. The nasolabial angle was unchanged. The concavity of the upper lip was reduced in complete unilateral and bilateral clefts. Certain characteristics of the oronasal region disclosed a similarity between incomplete cleft lip and palate (in unilateral involvement) and cleft lip alone, however global deviations (due to skeletal changes) were identical with those recorded in complete clefts.
