This article discusses how several diagnostic tools used by audiologists inter-relate to anatomical abnormalities viewed by video otoscopy. Background of common middle ear pathology is reviewed, with emphasis on new research findings regarding pathophysiology. A review of video otoscopy, multifrequency tympanometry, and otoreflectance is provided. Case studies illustrate the integrated use of these diagnostic tools. Audiologic results are integrated with video otoscopy through case study analysis and interpretation. Understanding of the complexity of the physiologic and behavioral measurements is enhanced with the ability to closely inspect tympanic membrane pathology through video otoscopy. Multifrequency tympanometry, otoreflectance, and otoacoustic emissions (OAEs) allow us to more easily detect pathologic conditions such as cholesteatoma and chronic (silent) otitis media with effusion (OME).
