The tongue has important roles in deglutition, speech, airway protection, taste, and sexual function, and its amputation is very serious. Using supermicrosurgical techniques, we replanted successfully a patient's tongue, the distal part of which had been amputated by the bite of another person, through the anastomosis of a blood vessel that was only 0.7-0.8mm. The result was that the state of the replanted tongue was relatively good both functionally and aesthetically, and the patient was very satisfied.
