Otolaryngology is a surgical field of medicine which studies the conditions associated with the parts of the head and neck, including the ear, nose and throat. It also deals with the treatment of various tumors and cancers, including the ones affecting the head and neck. One of the most common surgical methods used to treat such cancers is microvascular head and neck reconstruction. The tissue which is usually moved during the surgical process is from the back, arms and legs. In the process, the transfer of the tissue to the head and neck allows the head and neck surgeons in rebuilding the patient's jaw and reconstructing the throat.
