Anatomy and Physiology of the Eustachian Tube

Update on eustachian tube dysfunction and the patulous eustachian tube.

PURPOSE OF REVIEW The purpose of this review is to summarize the recent knowledge on eustachian tube dysfunction and the patulous eustachian tube. RECENT FINDINGS A clinically useful test for eustachian tube function is still lacking. Narrowing of the isthmus alone was demonstrated to be an insufficient cause of otitis media. Inflammatory mediators identified within the eustachian tube and mi...

Recent advances in otitis media. 2. Eustachian tube, middle ear, and mastoid anatomy; physiology, pathophysiology, and pathogenesis.

OBJECTIVE This report reviews the literature to identify the advances in our understanding of the middle ear (ME)-Eustachian tube (ET) system during the past 4 years and, on that basis, to determine whether the short-term goals elaborated in the last report were achieved and propose updated goals to guide future otitis media (OM) research. DATA SOURCES Databases searched included PubMed, Web ...

Dermoid of the eustachian tube.

Evolution of Eustachian tube surgery.

Eustachian tube dysfunction (ETD) is a common condition that lacks a widely accepted treatment. Attempts to address ETD surgically have spanned several centuries and have often fallen short of success. It is probable that occult anatomic position, unclear function, and misunderstood physiology have contributed to the delayed development of effective interventions for ETD. This article traces th...

Osseous Hamartoma Arising from the Eustachian Tube

A fairly quite rare case of osseous tumor arising from the Eustachian tube (ET) is described. A 56-year-old man presented with a smooth bulky mass in the nasopharynx and secretory otitis media in the right ear. Computed tomography and magnetic resonance imaging indicated a solid tumor-like region occupying the nasopharynx with apparent extension to the right ET. Transnasal endoscopic surgery de...
