Adipofascial Infragluteal Perforator Flap for Total Parotidectomy Reconstruction: A Novel Application for Inconspicuous Donor and Recipient Site-Preliminary Results.

Defects following total parotidectomy represent a distinctive reconstructive challenge. Restoration of facial volume and contour must be balanced with protection of the preserved facial nerve and reliable healing, particularly after extensive dissection and when adjuvant radiotherapy is anticipated. Multiple reconstructive options exist, each involving trade-offs regarding volume, pliability, long-term stability, and donor-site morbidity. We report our early clinical experience using the adipofascial infragluteal perforator (AIGP) free flap for reconstruction after total parotidectomy with skin and facial nerve preservation. We retrospectively reviewed the results of three consecutive patients undergoing total parotidectomy for parotid tumors, receiving immediate reconstruction with an AIGP free flap, operated between June and July 2025. The flap, based on terminal branches of the infragluteal vessels, was anastomosed to cervical recipient vessels. To address the two-compartment defect created by facial nerve preservation, the adipofascial tissue was tailored in a chimeric configuration to separately restore the superficial and deep parotid spaces. All flaps survived. One patient developed a postoperative hematoma managed conservatively. Two patients developed minor donor-site seromas after drain removal, which resolved without intervention. Facial contour was satisfactorily restored in all cases, with mild overcorrection in one patient. Facial nerve function improved during follow-up. Donor-site scars were concealed within the infragluteal crease. In this preliminary case series, the AIGP free flap proved to be a feasible option for reconstruction after total parotidectomy with skin and facial nerve preservation, offering satisfactory contour restoration and low donor-site morbidity. Larger studies with longer follow-up are required to define indications and long-term outcomes.
