Age was on average from (18-25) years. The sample was chosen randomly over a period of one year. For each participant a standard lateral cephalogram radiograph was taken. Result: A total of 100 lateral cephalogram radiographs were analyzed. The data showed that H angle is larger in male adults than females; indicate that facial convexity is more in male adults. While the total nose prominence and the lower lip showed insignificant gender differences in our sample. Conclusion: Holdaway found that orthodontic treatment goals were much improved when soft tissues features were taken into account during treatment planning.
