To evaluate the incidence of nasocutaneous fistula (NCF) development, following en bloc resection of lacrimal outflow system malignancies (LOSM), and describe the methods of surgical repair. Retrospective review of all patients who underwent resection of LOSM with reconstruction and post-treatment protocol at the University of Miami between 1997 and 2021. Of the 23 included patients, 10 (43%) developed postoperative NCF. All NCFs developed within one year of surgical resection or completion of radiation therapy. NCF was seen more frequently in patients who underwent adjuvant radiation therapy and those who had reconstruction of the orbital wall with titanium implants. All patients underwent at least one revisional surgery to close the NCF, including local flap transposition (9/10), paramedian forehead flap (5/10), pericranial flap (1/10), nasoseptal flap (2/10), and microvascular free flap (1/10). Local tissue transfer, pericranial, paramedian, and nasoseptal forehead flaps failed in most cases. Two patients had long-term closure; one patient who underwent a paramedian flap and a second who underwent a radial forearm free flap, suggesting that well-vascularized flaps may be the most viable option for repair. NCF is a known complication, following en bloc resection of lacrimal outflow system malignancies. Risk factors for formation may include adjuvant radiation therapy and use of titanium implants for reconstruction. Surgeons should consider utilizing robust vascular-pedicled flaps or microvascular free flaps for repair of NCF in this clinical scenario. [ABSTRACT FROM AUTHOR] |
