Summary
Amputated ears, especially those with partial amputation, can survive with prompt medical care and arterial repairs. Complete ear avulsion with arterial repair alone may not ensure long-term survival.
Area of Science:
- Reconstructive surgery
- Microsurgery
- Trauma care
Background:
- Scalping injuries can result in ear amputation, posing reconstructive challenges.
- The viability of amputated ear tissue is a critical concern in trauma management.
Purpose of the Study:
- To evaluate the survival outcomes of amputated ears following reconstructive surgery.
- To determine the impact of arterial and venous repairs on ear tissue survival.
Main Methods:
- Review of cases involving amputated ears due to scalping injuries.
- Analysis of surgical interventions, including arterial and venous anastomoses.
- Assessment of tissue perfusion and viability post-replantation.
Main Results:
- Subtotally amputated ears demonstrated good survival rates, particularly with arterial repairs.
- A case of complete ear avulsion with arterial repairs showed initial perfusion but ultimately failed, suggesting the importance of venous drainage.
Conclusions:
- Arterial repair is crucial for the survival of subtotally amputated ears.
- Successful replantation of completely avulsed ears may necessitate both arterial and venous repairs for sustained viability.
