The fact that the sensations of touch, pain and temperature eventually return in skin grafts and in pedunculated flaps of skin1 and subcutaneous tissue after transplantation has been known to surgeons for a long time, but so far as we are able to ascertain, no attempt has been made to find out what the early sensations are in pedunculated flaps and what relationship these sensations have to each other.
Several years ago, we began to gather from our clinical work in plastic surgery data which could eventually be analyzed and from which we hoped to obtain definite information as to these points. A large amount of material has been accumulated, and from this we have selected small groups of flaps of different types, which are typical and which indicate the results obtained.
It will be noted that the observations listed in this report deal entirely with pedunculated flaps and
