최근 5년간 시행한 구순열 및 구개열에 대한 고찰

The congenital deformities of cleft lip and cleft palate have been known to afflict man since prehistoric time. Efforts to correct these abnormities have evolved over the centuries as scientific knowledge has advanced. Although there is no agreement as to when the surgery should be performed, most surgeons adhere to "rule of 10" : the infant must be 10 week old weigh 10 Ibs, have a hemoglobin value 10gm/dl and have a white blood cell count no greater than 10 $thousands/mm^3$. Consensus favors performing initial palatal surgery in the child when he is between 18 and 24 months old. The timing of cleft alveolus surgery is usually between 10 and 11 years old. In the period from 1992 to 1996, 38 patients with cleft lip and cleft palate treated at the department of oral and maxillofacial surgery, Chosun university, dental hospital were analysed clinically. The obtained results were as follows. 1. The ratio of male to female was 1.92 : 1 (25/23) 2. The ratio of cleft lip, cleft palate and cleft lip & palate was 1.5 : 1 : 2.5 (12/8/18) 3. The ratio of unilateral to bilateral cleft lip was 5 : 1 (25/5) 4. The ratio of left to right side in unilateral cleft lip was 1.5 : 1 (15/10)
