[Near-total ear amputation: anatomical bases and management].

Journal Article (English Abstract;Journal Article)

BACKGROUND: In cases of near-total ear avulsions, replantation is often successful without microsurgery. The purpose of our study was to investigate the relevant vascular anatomy associated for ear survival. PATIENTS AND METHODS: Four cases of successful surgical intervention in near-total ear avulsions are presented. Injection studies using latex were performed to identify the blood supply to the auricle on 13 cadaveric ears. RESULTS: A small superior branch of the superficial temporal artery above the tragus was identified extending along the upper border of the auricle and connecting with the helical arcade. Below the tragus, a second small horizontal branch of the superficial temporal artery was identified. CONCLUSION: The auricle can survive near-total amputation based on a skin bridge above or below the tragus. One of the auricular branches of the superficial temporal artery seems sufficient for the blood supply to the ear and allows for a successful non-microsurgical operative repair.
