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

초록

BACKGROUNDVarious reconstruction options have been introduced to treat decubitus ulcers. A combined flap that takes advantage of the fasciocutaneous and muscle flaps has been proven to be effective in reconstructing decubitus ulcers in previous studies. However, no studies have measured combined flap thickness. This is the first study to demonstrate the superiority of the combined flap by measuring its thickness using enhanced abdominopelvic computed tomography (APCT).AIMTo evaluate combined flap modality as a useful reconstruction option for decubitus ulcers using measurements obtained through APCT.METHODSFifteen patients with paraplegia who underwent combined flap surgery for reconstruction of decubitus ulcers between March 2020 and December 2021 were included. The defects in the skin and muscle components were reconstructed separately. The inner gluteus muscle flap was split and manipulated to obliterate dead space. The outer fasciocutaneous flap was transposed to cover the muscle flap and opening of the decubitus ulcer. Subsequently, we performed enhanced APCT at 3 wk and 6 mo postoperatively to measure the flap thickness.RESULTSThe mean flap thickness was 32.85 +/- 8.89 mm at 3 wk postoperatively and 29.27 +/- 8.22 mm at 6 mo postoperatively. The flap thickness was maintained without any major complications such as contour deformities or recurrence.CONCLUSIONAlthough there was a significant decrease in flap thickness as measured by APCT, the combined flap provided sufficient padding and maintained its thickness even at 6 mo after reconstruction, suggesting that the combined flap modality may be a useful reconstruction option for patients with paraplegic decubitus ulcers.
