Regeneration of muscle following cryosurgery of the tongue.
Regeneration of muscle following low-temperature destruction of tissue has not been extensively studied. Using light and transmission electron microscopy an investigation of this phenomenon was made in hamster tongue. Healing commenced 1 week after the operation and was of the continuous regeneration type in the least damaged muscle fibers. Healing was of the discontinuous or embryonic type in severely damaged muscle and myoblasts formed either within old intact endomysial tubes or separate from them. Healing with minimal scarring was well advanced 6 weeks after the operation.
