A cephalometric radiographic cross sectional comparative study was undertaken to invertigate craniofacial growth in cleft lip and palate individuals. The material for this study consisted of 43 subjects with operated cleft lip and palate.(29 males, 14 females). The range of age was from 6 years to 12 years. The roentgenocephaometric values of cleft individuals were compared with values of normal individuals reported by Lee. 28) The following conclusions were obtained ; 1) The pattern of cranial base of the clegt subjects was almost the same as that prviously reported for the normal individuals. 2) Anterio-posterior length of the mandible did not show any significant difference but in the cleft subjects, that od the males was larger than that of the females. 3) The maxilla of the cleft subjects was very retruded and showed very concave profile. 4) Gonial angle of the cleft subjects was very high, especially in the female clefts. 5) The hegth of ramus was very poor in the cleft subjects. 6) The facial length was almost the same, but the facial depth of the cleft subjects was smaller than that of the normal individuals. 7) Maxillary and mandibular incisorswere severely retroclined. 8) The range of values in the cleft subjects was very variable and the female clefts showe more distured growth than the male clefts.
