Measurement of combined flap thickness for reconstruction of decubitus ulcer using computed tomography

Figure 1 A 58 years old male patient with grade IV decubitus ulcer on ischial region. A: Intraoperaetive findings: Discrepancy between opening (3 cm² × 3 cm²) and soft tissue defect (7 cm² × 3 cm²); B: Is observed. Design of Inferior gluteal artery based fasciocutaneous flap, inferior 1/3 portion of gluteus maximus muscle is splitted and transpositionted to cover exposed ischial tuberosity; C: Immediate postoperative findings; D: Postopertive phogograph at 6 mo follow up: No concavity is observed on the flap.

Figure 2 Computed tomography findings. A: Preoperative computed tomography (CT) findings: Reference point (orange arrow); B: Postoperative CT findings after 3 wk from reconstruction: Distance between reference point and skin is measured 27.77 mm (yellow arrow); C: Postoperative CT findings after 6 mo from reconstruction: Distance between reference point and skin is measured 24.56 mm (yellow arrow).

Figure 3 Evaluation of combined flap thickness. The mean flap thickness of 3 wk postoperative computed tomography (CT) image was 32.85 ± 8.89 mm. The mean flap thickness of 6 mo postoperative CT image was 29.27 ± 8.22 mm (P value < 0.05).
