Summary
Microsurgical replantation offers the best cosmetic results for traumatic ear amputations when feasible. Simple reattachment is recommended for smaller amputations, while complex cases may require reconstruction or prosthetics.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Trauma Surgery
Background:
- Traumatic ear amputations present significant surgical challenges.
- Replantation techniques must prioritize vascular supply and tissue preservation for potential future reconstruction.
- Managing these injuries requires careful consideration of surgical options and patient outcomes.
Purpose of the Study:
- To review and synthesize existing literature on surgical techniques for traumatic ear amputations.
- To evaluate the effectiveness of different methods for managing partial or total ear amputations.
Main Methods:
- A systematic literature search was conducted using PubMed, ScienceDirect, and Cochrane Library.
- Articles were selected and reviewed in accordance with PRISMA statement guidelines.
- Sixty-seven relevant articles were included in the synthesis.
Main Results:
- Microsurgical replantation, when possible, yielded the best cosmetic outcomes but demanded meticulous care.
- Pocket techniques and local flaps resulted in lower cosmetic results and compromised surrounding tissues.
Conclusions:
- Microsurgical replantation is the preferred method for ear amputations when feasible, requiring patient consent for necessary interventions.
- Simple reattachment is advised for earlobe and up to one-third ear amputations.
- For larger amputations where microsurgery is not possible, simple reattachment carries a higher failure risk; reconstruction or prosthetics are alternatives in case of failure or non-viability.
