Oto‑ comes into play as a combining form (often written o- when broken out in med‑term class) to build terms for ear anatomy, pathology, and procedures. In practice you’ll see it across specialties: otology (ear subspecialty of ENT), otitis media/externa (ear infections), ototoxic (ear‑damaging drugs), and otoplasty (plastic surgery of the external ear).

greek “Oto‑” derives from Ancient Greek οὖς (ous), genitive ὠτός (ōtós), meaning “ear,” with the combining stem ōt- that gives us ot‑/oto‑ in scientific and medical vocabulary. It parallels the Latin‑derived aur‑/[[auri‑]] (as in aural) which also means “ear,” but oto‑ is the standard Greek form in most medical terminology lists.
