Free double-paddle superficial circumflex iliac perforator flap transfer for partial maxillectomy reconstruction: A case report.

Partial maxillectomy for maxillary sinus cancer treatment requires soft tissue reconstruction with enough bulk to occupy the large-volume defect. Deep inferior epigastric artery-based flaps and subscapular artery-based flaps are commonly used, but necessitate invasive muscle dissection or position change and a large recipient vessel. The aim of this report was to present a case of partial maxillectomy defect successfully reconstructed with a superficial circumflex iliac artery (SCIA) perforator (SCIP) flap, to address these drawbacks. A 67-year-old female underwent partial maxillectomy for maxillary sinus cancer. The defects included the medial and the caudal aspects of the maxillary sinus with unilateral palate loss. A double-paddle SCIP flap (19 × 9 cm and 10 × 6 cm) was elevated in a free-style manner based on the superficial branches of the SICA. The SCIP and its concomitant vein were anastomosed to a facial artery perforator and the angular vein with supermicrosurgical perforator-to-perforator anastomosis. Two skin paddles were utilized to reconstruct the defects of the nasal wall and the oral aspects of the palate. Postoperative course was uneventful, and the patient could resume normal oral diet 5 days after surgery. Three years after surgery, there was no cancer recurrence or any postoperative complication, and the patient was satisfied with normal speech and diet, and with concealable donor and recipient scars. Double-paddle SCIP flap transfer may be an option for reconstruction of a partial maxillectomy defect.
