Head and neck reconstruction in vessel-depleted necks: Case report of a labio-mental and mandibular reconstruction using an arteriovenous loop.

Major defects of the facial structures cause severe functional and esthetic impairment. Difficulty in head and neck reconstruction lies in cases of secondary, tertiary, or further reconstruction. This is not a rare situation for patients who had cancer of the upper airways, since the rate of recurrence, second location, or osteoradionecrosis is high. Multiple surgeries and radiation therapy cause significant fibrosis and scar tissues, making any further reconstruction a major challenge for the surgeon when operating patients with vessel- depleted neck. We report our experience with a clinical case of a patient to whom we performed a double free flap reconstruction anastomosed on a vascular loop in a context of vascular cervical desert. In our case, the use of an arteriovenous loop proved to be a reliable approach for a vessel-depleted free tissue reconstruction. This technique has received insufficient attention, yet it provides a means to establish dependable vascular alternatives.
