[Study of surgical depilation in pig and human body].
OBJECTIVE
The study is to show how much dermis and the follicles within it should be removed in order to prevent hair regeneration.


METHODS
The experiment used Wuzhishan mini pigs. Different thickness of the pig's dermis and the follicles within it were removed to observe hair regeneration. According to the result, the dermis and the follicles were removed from the scalps of 62 patients from Jan. 1995 to Dec. 1996. Subsequent hair regeneration was observed.


RESULTS
Using surgical depilation to remove 1/4-2/5 thickness of the scalp dermis and the follicles within it stopped most of the hair regeneration. The rate of hair regeneration was 10-30%. Satisfactory clinical effects were achieved.


CONCLUSIONS
Surgical depilation is a simple, effective, cheap way for hair removing.
