Summary
Triple rhomboid flaps offer a practical solution for reconstructing large defects after skin cancer surgery. This method proved effective and well-tolerated in patients, showing promising results for truncal reconstruction.
Area of Science:
- Dermatologic Surgery
- Reconstructive Surgery
- Surgical Oncology
Background:
- Reconstructing large defects after skin cancer removal presents significant surgical challenges.
- Effective methods for large truncal defects are crucial in dermatologic and reconstructive surgery.
Purpose of the Study:
- To present triple rhomboid flaps as an accessible and effective technique for reconstructing large truncal defects.
- To evaluate the feasibility and outcomes of using triple rhomboid flaps in patients undergoing malignant skin tumor excision.
Main Methods:
- A retrospective case series involving nine patients with large truncal defects (5x5 cm to 17x15 cm) after malignant skin tumor excision.
- Reconstruction was performed using the triple rhomboid flap technique.
Main Results:
- All nine flaps survived without major postoperative complications.
- Incisions healed successfully in a single phase, with high satisfaction reported by both patients and medical professionals.
Conclusions:
- The triple rhomboid flap is a feasible, practical, and easy-to-perform reconstructive option for selected large truncal defects.
- This technique may be particularly valuable for dermatologic surgeons in settings lacking complex microsurgical facilities.
- Further research with larger patient groups and longer follow-up is warranted to confirm long-term outcomes.
