The "super-thin" flap.

The so-called "super-thin" flap was devised in China and these flaps have been in general use since about 1982. However, detailed descriptions of the flaps have rarely appeared in English Language journals. In this paper, we present the development of our use of these flaps in clinical cases, and discuss some factors which seem to contribute to the increase of the survival area of the distal portion of these so-called "super-thin" flaps.
