Complete replantation of a small tissue segment at the auricular apex: A case report.

ABSTRACT: This study reports a rare case of complete replantation of a small avulsed tissue segment at the auricular apex. The patient, a 30-year-old male, sustained a complete amputation of the left ear apex due to a traffic accident. The avulsed tissue had been ischemic for approximately 4 h prior to surgery. Using supermicrosurgical techniques under 30 × magnification, three vessels-one artery and two presumed veins, each with a diameter of approximately 0.2-0.4 mm-were successfully anastomosed. Postoperatively, the patient developed venous congestion, which was effectively managed through regular acupuncture bleeding, leading to restored venous outflow. The tissue survived completely, and during a 3- to 6-month follow-up, the patient showed no significant hearing loss, with good auricular contou
