Precise photographic documentation is of significant importance for proper diagnosis and management of physiological and pathological conditions of the larynx. Since the fiberscope serves an important role in the daily practice of laryngologists, its value is greatly enhanced when coupled with a video camera. Fiberoptic videolaryngoscopy permits instant and simultaneous voice and visual recordings for later study. The procedure is most useful for analysis of respiration, phonation, singing, and other laryngeal functions such as glottic closure, swallowing, and protective-compensatory movements. The procedure also allows investigation of various pathological conditions. The purpose of this paper is to present the authors' method of fiberscopic videolaryngoscopy and its relevant clinical implications. Advantages and disadvantages of the procedure are discussed.
Rinne tests were done on 214 ears with various air‐bone gaps, using both steel and magnesium tuning forks, in the method described by Shambaugh. Predictability of air‐bone gap was evaluated, and found to be only moderately good. An air‐bone gap of 15 db or more can usually be demonstrated with use of the 256 fork but accuracy in determining the amount of gap between 15 db and 45 db is poor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
