The Function of the Eustachian Tube
Archives of Otolaryngology - Head and Neck Surgery, 1960An air-containing middle ear is necessary for normal hearing, both because it allows free vibration of the eardrum and ossicles so that sound pressure can be transmitted to the inner ear fluid and because it affords protection from sound to the round window.

Physiology of the Eustachian Tube
Archives of Otolaryngology - Head and Neck Surgery, 1973The function of the eustachian tube is to maintain pressure equality across the tympanic membrane. A number of tests have been utilized to study the condition of the eustachian tube. Of these, some tests measure only patency. Several methods have been devised to test tubal function by determining the tubal transport of sound, air, radiopaque media ...

OBSERVATIONS ON THE EUSTACHIAN TUBE
Archives of Otolaryngology - Head and Neck Surgery, 1951ON PERUSAL of current literature one notes that despite a great deal of clinical observation on the eustachian tube, the understanding of its physiological role as a ventilator of the middle ear is limited. To broaden the knowledge of this function in man under ordinary conditions, more experimental observations are needed. These have been difficult to

Archives of Otolaryngology - Head and Neck Surgery, 1951
THE CONDITION of patulous Eustachian tube, while not very common, is much more prevalent than is usually supposed. It is, in all probability, frequently overlooked and has seldom been discussed. In looking through a large number of the standard textbooks on otolaryngology one can find very few that even mention it.

Anatomy of the Eustachian Tube
Archives of Otolaryngology - Head and Neck Surgery, 1973It is well to review the anatomy of the eustachian tube from time to time and to tie it in with new concepts of its function, pathology, and methods of treating abnormal and diseased states. The protympanum or bony portion of the eustachian tube is the site of some tubal occlusions and we are concerned with normal structures so that we can deal better

Endoscopy of the Eustachian Tube
1985The author introduced a systematic procedure of endoscopy of the Eustachian tube using the flexible fiberscope with and without an instrumentation channel. A relatively free approach allows a detailed examination of the tubal orifice. And the tubal lumen of the cartilaginous portion is examined using the fiberscope with a channel for air insufflation ...

Pathophysiology of the Eustachian Tube: The Patulous Eustachian Tube
2013The impairment of the physiological protection function of the Eustachian tube causes a distressing autophony and aural fullness, the so-called syndrome of the patulous Eustachian tube (pET) [13, 74, 130]. The pET as it is described here to a certain extent is just the “tip of the iceberg” in the general complex of Eustachian tube closing failure [108].

There are several types of eustachian tube dysfunction, including obstruction and abnormal patency. This article presents an update on several selected areas of eustachian tube function and dysfunction, including surfactants, cleft palate, tympanic membrane atelectasis, abnormal eustachian tube patency, and long-term middle ear ventilation.

Anatomy of the Eustachian Tube
Otolaryngologic Clinics of North America, 2016The eustachian tube consists of 2 compartments: the Rüdinger's safety canal and the auxiliary gap. It is surrounded by a cartilaginous wall on the craniomedial side and a membranous wall on the inferolateral side. The eustachian tube cartilage is firmly attached to the skull base by the lateral and the medial suspensory ligaments, which are separated ...
