Summary
Near-total ear avulsions can be successfully repaired without microsurgery. A single auricular branch of the superficial temporal artery can provide sufficient blood supply for ear survival and non-microsurgical repair.
Area of Science:
- Plastic Surgery
- Anatomy
- Trauma Surgery
Background:
- Replantation of near-total ear avulsions is often successful without microsurgery.
- Understanding the vascular anatomy is crucial for successful ear survival.
Purpose of the Study:
- To investigate the vascular anatomy relevant to ear survival in near-total ear avulsions.
- To identify the specific blood vessels supplying the auricle.
Main Methods:
- Presentation of four cases of successful surgical intervention for near-total ear avulsions.
- Latex injection studies on 13 cadaveric ears to map auricular blood supply.
Main Results:
- A superior branch of the superficial temporal artery was identified, supplying the upper auricle and connecting to the helical arcade.
- A second, smaller horizontal branch of the superficial temporal artery was found below the tragus.
Conclusions:
- The auricle can survive near-total amputation if a skin bridge exists above or below the tragus.
- A single auricular branch of the superficial temporal artery is sufficient for ear survival.
- Successful non-microsurgical repair of ear avulsions is feasible.
