Summary
The orbitonasolabial flap, utilizing a constant angular vessel pedicle, offers a reliable method for reconstructing central facial defects. This vascular island flap demonstrated good outcomes in patients with jugular, orbital, and nasolabial defects.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Anatomy
Background:
- The orbitonasolabial flap is a reconstructive option for facial defects.
- Its vascular supply via the angular vessel pedicle requires anatomical validation.
Observation:
- Anatomical study on 11 cadavers confirmed a consistent angular vessel pedicle.
- The flap was utilized in 6 patients (aged 62-90) for jugular, orbital, nasolabial, and inner canthal defects over 16 months.
Findings:
- The orbitonasolabial flap proved reliable for central facial defect reconstruction.
- Minor complications included superficial flap necrosis (healed spontaneously) and ectropion.
- Secondary debulking was needed in 50% of cases.
Implications:
- This flap provides a viable solution for complex facial tissue defects.
- It offers acceptable aesthetic and functional outcomes at the donor site.
- Further studies can refine its application in various reconstructive scenarios.
