Sensibility and sensory reinnervation were investigated in 19 free flaps, predominantly located on the lower extremities, between 2 months and 3 years after flap transfer. All patients showed deep pressure sensibility. In 10 of the patients, primarily those examined late after surgery, a heat pain threshold was obtained at about 50 degrees C. None of the patients had superficial sensibility of any other modality. No neurofilament-positive sensory nerve fibers were observed in the dermis or epidermis. In one patient nerve fibers were detected in the subcutaneous tissue. It is concluded that patients will have deep pressure sensibility of the flap area even early after the operation and that most patients will develop a heat pain sensitivity, probably due to subcutaneous reinnervation.
在皮瓣移植后2个月至3年期间，对19例主要位于下肢的游离皮瓣进行了感觉和感觉再支配的研究。所有患者均表现出深部压力感觉。在10例患者中，主要是那些术后检查较晚的患者，热痛阈值约为50摄氏度。没有患者具有任何其他形式的浅感觉。在真皮或表皮中未观察到神经丝阳性感觉神经纤维。在1例患者的皮下组织中检测到神经纤维。结论是，患者即使在术后早期皮瓣区域也会有深部压力感觉，并且大多数患者可能由于皮下再支配而会出现热痛敏感性。
