Free perforator flap transfer for reconstruction of skull base defects after resection of advanced recurrent tumor.

Background: Skull base reconstruction is challenging due to its proximity to important anatomical structures. This report evaluates the use of perforator flaps for reconstruction of skull base defects after advanced recurrent tumor resection.

Methods: Fourteen free perforator flaps were transferred to reconstruct skull base defects in 14 consecutive patients, from October 2004 to May 2011. All patients had advanced recurrent neoplasms that were previously treated with either radiation therapy or surgery. The surgical defects were reconstructed using various perforator flaps mainly the deep inferior epigastric artery perforator flaps, anterolateral thigh (ALT) flaps, or thoracodorsal artery perforator flaps. The outcomes following reconstruction and associated complications were evaluated.

Results: The overall free flap success rate was 93% (13/14). One ALT flap was lost. Three patients (20%) had a cerebrospinal fluid fistula, and two of them developed meningitis. No complications were observed at the donor site.

Conclusions: The use of perforator flaps may be a viable option for reconstruction of skull base defects after the resection of advanced recurrent tumor.
