Methodology of otology and otosociology. Otology considers audiovestibular symptoms (deafness, vertigo, tinnitus, hyperacusis, and aural fullness) and places their aetiology, pathogenesis, diagnosis, and treatment within the ear. Otosociology places them within the ear and the individual’s environment. ENT: ear-nose-throat. FLAIR: fluid attenuated inversion recovery. NMR: nuclear magnetic resonance.
