Microvascular reconstruction is an advance form of reconstructive surgery whereby tissue with arteries and veins from your arm, leg, chest or back are harvested and utilized to reconstruct your face, scalp, throat or mouth. The microvascular portion involves suturing these small vessels (2-3mm wide) to arteries and veins in the neck to re-establish a blood supply to the tissue. This is a technically demanding procedure that requires the use of a microscope and suture that is finer than human hair. This procedure has been shown to improve outcomes in terms of maintaining the function of the head and neck and better aesthetic outcomes for patients with traumatic and congenital defects or require surgery for head and neck cancer.
