=== Microvascular reconstruction repair ===
Microvascular reconstruction repair is a common operation that is done on patients who see an otorhinolaryngologist. It is a surgical procedure that involves moving a composite piece of tissue from the patient's body and to the head and/or neck. Microvascular head-and-neck reconstruction is used to treat head-and-neck cancers, including those of the larynx and pharynx, oral cavity, salivary glands, jaws, calvarium, sinuses, tongue and skin. The tissue that is most commonly moved during this procedure is from the arms, legs, and back, and can come from the skin, bone, fat, and/or muscle.<ref>{{Cite web|url=https://www.ucsfhealth.org/treatments/microvascular_head_and_neck_reconstruction/|title=Microvascular Head and Neck Reconstruction - Conditions & Treatments|website=ucsfhealth.org|access-date=2018-12-06}}</ref>

When performing this procedure, the decision on which is moved is determined on the reconstructive needs. Transfer of the tissue to the head and neck allows surgeons to rebuild the patient's jaw, optimize tongue function, and reconstruct the throat. When the pieces of tissue are moved, they require their own blood supply for a chance of survival in their new location. After the surgery is completed, the blood vessels that feed the tissue transplant are reconnected to new blood vessels in the neck. These blood vessels are typically no more than 1 to 3&nbsp;millimeters in diameter, which means that these connections need to be made with a microscope, which is why the procedure is called "microvascular surgery".{{citation needed|date=June 2022}}
