The ear has auditory and vestibular functions. In many lizards the external ear is greatly reduced and most species have a superficial tympanum. Exceptions include geckos and monitors which have external ear canals.
There is a single ossicle, the columella. Middle and inner ears and eustachian tubes are present.
