Otorhinolaryngology (/oʊtoʊˌraɪnoʊˌlærɪnˈɡɒlədʒi/ oh-toh-RY-noh-LARR-in-GOL-ə-jee, abbreviated ORL and also known as otolaryngology, otolaryngology – head and neck surgery (ORL–H&N or OHNS), or ear, nose, and throat (ENT) ) is a surgical subspecialty within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians.

Patients seek treatment from an otorhinolaryngologist for diseases of the ear, nose, throat, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face, scalp, and neck.

Etymology

The term is a combination of Neo-Latin combining forms (oto- + rhino- + laryngo- + -logy) derived from four Ancient Greek words: (cf. Greek ωτορινολαρυγγολόγος 'otorhinolaryngologist').

οὖς (ous), 'ear', whose genitive is ὠτός (otos)
ῥίς (rhis) 'nose'
λάρυγξ (larynx) 'larynx'
-λογία (logia) 'study'

Training

Otorhinolaryngologists are physicians (MD, DO, MBBS, MBChB, etc.) who complete both medical school and an average of five–seven years of post-graduate surgical training in ORL-H&N. In the United States, trainees complete at least five years of surgical residency training. This comprises three to six months of general surgical training and four and a half years in ORL-H&N specialist surgery. In Canada and the United States, practitioners complete a five-year residency training after medical school.

Following residency training, some otolaryngologist-head & neck surgeons complete an advanced sub-specialty fellowship, where training can be one to two years in duration. Fellowships include head and neck surgical oncology, facial plastic surgery, rhinology and sinus surgery, neuro-otology, pediatric otolaryngology, and laryngology. In the United States and Canada, otorhinolaryngology is one of the most competitive specialties in medicine in which to obtain a residency position following medical school.

In the United Kingdom, entrance to higher surgical training is competitive and involves a rigorous national selection process. The training programme consists of 6 years of higher surgical training after which trainees frequently undertake fellowships in a sub-speciality prior to becoming a consultant.

The typical total length of education, training and post-secondary school is 12–14 years. Otolaryngology is among the more highly compensated surgical specialties in the United States. In 2022, the average annual income was $469,000.

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.

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 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]}
