This study analysed 427 cases of breech presentation among the total 13613 deliveries during the period from Jan. 1977 to Dec. 1983 at St. Benedict Hospital, Department of Obstetrics and Gynecology. This data was divided into 2 groups of vaginal delivery group and cesarean section group, and then, was reviewed for mothers age, parity, birth weight, perinatal mortality and Apgar score at 5 minutes. 1. The incidence of breech presentation was 3.1%. 2. Predominant age group consisted of 25~29 age group with frequency of 52.2%. 3. As to the parity, the frequency of breech presentation was 73.9% in primipara and 52.3% in multipara (p<0.001). 4. As birth weight was increased, the frequency of cesarean section was done, 67.7% in 2500~2999gm group, 74.3% in 3000~3499gm group and 88.9% in over 4000gm group. 5. In 2500gm or more group, perinatal mortality rate was 4.6% in vaginal delivery and 0.8% in cesarean section. 6. Birty weight in breech presentation was smaller than vertex presentation. At 38 weeks, 40 weeks, 41 weeks, the difference of birth weight was meaningful (p< 0.05, p<0.01, p<0.01). 7. As to type of delivery, perinatal mortality was 5 of 5 cases in vaginal delivery and 2 of 4 cases in cesarean section at 33 weeks and 4 of 7 cases of vaginal delivery and 1 of 8 cases in cesarean section at 34 weeks therefore, cesarean section was favorable type of delivery in prematurity. 8. Perinatal mortality rate was 13.1% and most common cause of death was prematurity and most common period of death was after delivery. 9. Cesarean section rate showed a tendency to gradual increment yearly.
