  • Title: Endoscopy of the eustachian tube: use of the fiberscope and the telescope.
    Author: Conticello S, Saita V, La Mantia I, Ferlito S.
    Journal: Arch Otorhinolaryngol; 1989; 246(5):256-8. PubMed ID: 2590028.
    Abstract:
    The necessity for direct observation of the pharyngeal outlet of the normal or pathological eustachian tube has always stimulated research for suitable diagnostic instruments. As the result of various investigation procedures currently available, we performed a series of endoscopic screenings using both the Hopkins telescope and the fiberoptic rhinopharyngolaryngoscope. The present study aimed at evaluating and demonstrating the morphological and dynamic functional condition of the pharyngeal outlet of the tube. The present investigation was carried out on 60 males and females, ranging in age from 4 to 70 years. Inspection of the pharyngeal outlet of the tube and its adjoining region enabled us to document some of the various causes for tubal dysfunction. By visualizing tubal movements, endoscopy also made it possible to perform a dynamic study of tubal functions. However, the investigation procedure utilized did not allow us to record any significant differences between the two diagnostic instruments used, except that the fiberscope can be more easily handled, whereas the photographs taken with the telescope are of better quality.
