Summary
This study demonstrates that axial pattern flaps, utilizing sternocleidomastoideus branches of the caudal auricular artery and vein, show significantly improved survival rates for head and neck reconstruction.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Vascular Anatomy
Background:
- Head and neck reconstruction presents challenges due to limited skin availability.
- Axial pattern flaps offer a potential solution by utilizing well-defined vascular pedicles.
Purpose of the Study:
- To evaluate the viability and efficacy of an axial pattern flap based on the sternocleidomastoideus branches of the caudal auricular artery and vein.
- To compare the survival rate of this flap with control flaps in a preclinical model.
Main Methods:
- An axial pattern flap was designed using the sternocleidomastoideus branches of the caudal auricular artery and vein.
- Control flaps were created with ligation and division of these vessels.
- Flap survival rates were monitored and compared between the two groups.
Main Results:
- Axial pattern flaps demonstrated a significantly higher mean survival rate (85.2%) compared to control flaps (63.9%).
- The difference in survival rates was statistically significant (P < 0.05).
Conclusions:
- An axial pattern flap based on the sternocleidomastoideus branches of the caudal auricular artery and vein is a viable option for head and neck skin reconstruction.
- This flap design offers improved tissue survival, potentially benefiting reconstructive surgery outcomes.
