Use of nasolabial flap for reconstruction of the floor of the mouth defects

Abstract

After an extensive tumor resection, a defect of the floor of the mouth is a significant reconstructive challenge. The main goal is to preserve the mobility of the tongue, which allows the restauration of mastication, deglutition, and articulation. Today, a standard method for reconstruction of floor of the mouth defects is free microvascular flaps, especially radial forearm free flap. Despite that, a potential problem is the high perioperative risk and high complication rate associated with the patient’s age and comorbidities. Current literature suggests that a local nasolabial flap is a reliable treatment option for reconstruction of this type of defect, with a low complication rate and excellent functional and aesthetic results. The aim of this case presentation is to show the use of a local nasolabial flap for reconstruction of the floor of the mouth and to determine the criteria for this type of reconstruction. We present a patient who underwent resection of a floor of the mouth tumor. Due to the patient’s age, medical condition, and comorbidities, the defect was reconstructed with a local nasolabial flap. There were no postoperative complications. Articulation, mastication, and deglutition were satisfactorily rehabilitated. Follow-up showed no signs of recurrent disease twelve months postoperatively. To conclude, a local nasolabial flap is still an important reconstructive choice for oral cavity defects, especially for elderly patients with multiple comorbidities who have a higher risk of perioperative complications.
