The field of dermatologic surgery has seen trementdous developments in the past few years.

Our purpose was to discuss current statistical data on the dermatologic patients treated by surgical methods at our institute.

We analyzed 2,334 cases of surgeries performed on 1,075 patients at the Department of Dermatology of Ewha Womans University Tongdaemun Hospital during a period of 5 years (1994. 1 - 1998. 12).

The results are summarized as folows:

2) The ratio of male to female was 1 : 2.4 and the mean age of patients was 30.3 years.

3) A total of 1,354 cases of diseases were managed surgically : among them, the most frequent disease was scar(39.8%), followed by pigmentary disorders(30.8%), and benign or malignant tumors(21.2%).

4) With respect to the types of scars, acne scar was treated most frequently by chemical peeling (72.7% of 580 cases), atrophic scar by dermabrasion(37.3% of 126 cases), and hypertrophic scar (including burn scars) by cryosurgery(35.3% of 85 cases).
