摘要

Objective

To evaluate the clinical efficacy of the De-Epithelialized Flap technique in the reconstruction of pressure ulcers in the buttocks and trochanteric regions.

Methods

A total of 29 patients with pressure ulcers in the buttocks and trochanteric regions were treated from January 2018 to November 2021, including 16 cases in the sacrococcygeal region, 4 in the intertrochanteric region, and 9 in the ischial tuberosity. Early debridement and drainage were performed to remove necrotic tissue and sinus tracts, followed by repair of the pressure ulcers using the De-Epithelialized Flap. The flap’s length in the advancement direction should measure approximately 1.5–2 times the diameter of the defect, with the width slightly exceeding that of the wound. Excess tissue at the recipient site is de-epithelialized and used to fill the dead space.

Results

Among the patients, 27 cases achieved primary healing of the skin flaps, while 2 cases experienced delayed wound healing. These wounds were successfully managed with dressing changes and debridement. During a follow-up period of 6–12 months, only 1 case of recurrence at the same site was observed.

Conclusion

The use of the De-Epithelialized Flap for the repair of pressure ulcers in the buttocks and trochanteric regions offers the benefits of being a simple, safe, and effective procedure with a low recurrence rate. This technique demonstrates promising clinical value and is recommended for broader clinical application.
