Abstract: Objective To explore the sensation recovery of the reconstructed penis by Cheng＇s method. Methods A long term follow-up of 27 patients undergoing penile reconstruction by Cheng＇s method were performed. Sensory testing including tactile sensation and static two-point discrimination was performed in a standardized pattern. Results The tactile sensation of the reconstructed glans began to recover 6 months after phalloplasty. The static two-point discrimination began to recover 6-12 months after operation and reach stability to 10-14 mm 2-3 years after operation. The tactile sensation of the reconstructed penile body began to recover 6 months after phalloplasty. The static two-point discrimination reached 15- 20 mm 6-12 months after operation. Conclusion The sensation recovery in reconstructed phallus by Cheng＇s method begin to recover 6 months after operation and reach stability after 2-3 years.
