Gluteus maximus adipomuscular turnover or sliding flap in the surgical treatment of extensive sacral chordomas.
Two cases with extensive posterior peritoneal defects after high sacral amputation for sacral chordoma are presented. An adipomuscular flap as a modification of the conventional gluteus maximus muscle flap was designed to obliterate an extensive residual posterior peritoneal dead space. The deep adipose tissue beneath the superficial fascia left on the gluteus maximus muscle was effectively used to provide more volume to the flap. The adipomuscular flap was turned over into the posterior peritoneal defect in the first case, and the flap was slid into the cavity in the other case. The adipomuscular flap eventually enabled the successful reconstruction of the posterior peritoneal defect, and the volume of the flap was well maintained behind the rectum, according to the postoperative magnetic resonance imaging findings in both cases.
