Abstract
To investigate the growth of nose and maxilla in cleft lip and palate, each angle between the nasal dorsal line, the auricular attaching line and the auricular long axis line was measured and analyzed. The subjects of the study were 3 month old infants and 69 cleft lip and palate, preoperative, 3 month old patients, and some 5-10 months old. The result were: 1) The order of the angle between the auricular attaching line and the nasal dorsal line was normal infant>unilateral cleft lip>unilateral cleft lip and palate>bilateral cleft lip and palate. Significant predominance was recognized in each other.2) The angle between the auricular attaching line and auricular long axis line decreased with increase in cleft width. Significant predominance was only between normal infants and bilateral cleft lip and palate. 3) The angle between the auricular long axis line and the nasal dorsal line had the same tendency, but there was no significant predominance between normal infants and unilateral cleft lip, nor between unilateral cleft lip and unilateral cleft lip and palate. Conclusion: In cleft lip and palate, maldevelopment of the maxilla was greater especially in cleft palate, and the auricular long axis line was not adequate for base line.
