Summary
The modified rotation Hemi-keystone flap offers excellent survival for cutaneous defect reconstruction. This versatile technique minimizes tension and morbidity, proving a reliable surgical option.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Dermatology
Background:
- The keystone perforator flap is a versatile reconstructive option but can cause excessive tension.
- A novel modified rotation Hemi-keystone flap was developed to address these limitations.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the modified rotation Hemi-keystone flap in reconstructing cutaneous defects.
Main Methods:
- A retrospective chart review of 40 patients who underwent reconstruction with the modified rotation Hemi-keystone flap between March and December 2021.
- The primary outcome assessed was successful flap survival.
Main Results:
- A total of 45 flaps were performed for defects in the head and neck (38%), extremities (35.7%), and trunk (26.2%).
- Tumor resection (45.2%) was the most common cause of defects, with mean dimensions of 3.5 cm × 3 cm.
- Flap survival was high, with only one case (2.4%) of minor wound dehiscence.
Conclusions:
- The modified rotation Hemi-keystone flap is a simple, reliable, and versatile technique.
- It minimizes reconstruction site morbidity and improves flap mobility, allowing for tension-free closure.
- This flap is an excellent surgical option for various soft tissue defects.
