Abstract: | The question as to whether anastomosis of sensory nerves is recommended for free transplants of the myocutaneous latissimus dorsi flap, reanastomosed by microvascular surgery, remains a controversial issue. In this study, a microsurgical nerve anastomosis was performed to sensitize a latissimus dorsi transplant. To determine sensation in the transplanted tissue, six patients were examined clinically. All patients had free transplants of latissimus dorsi flaps reanastomosed by microvascular surgery after tumor resection in the oral cavity. An anastomosis of the sensible auricular magnus nerve with the motor thoracodorsalis nerve was performed. Resulting sensation was determined clinically by testing for pain, temperature, pressure, two-point discrimination, and vibration. All patients showed sensation in the latissimus dorsi flap beginning between the third and the fifth month postoperatively. Therefore, resensitization of a large and voluminous myocutaneous latissimus dorsi flap should be attempted by a nerve anastomosis in this transplant. |
