Imaging for the middle and inner ear can be challenging, as conventional computed tomography and magnetic resonance imaging show limited resolution in time and space. Although relatively few studies exist on optical coherence tomography in this field, in vitro and in vivo, it has been shown that morphological data concerning middle ear structures and pathology such as biofilm can be identified with resolution in the range of few μm. In addition, image acquisition is now fast enough to assess sound transmission of middle ear ossicles, as well as capillary blood flow within the cochlea in real time. Thus, OCT is a powerful new tool for the clinician as well as for the researcher in otology, opening new horizons for office-based diagnosis and the understanding of middle and inner ear function.
