Upper respiratory system, showingentrance to auditory tube near middle.

The Eustachian tube extends from the anterior wall of the middle ear to the lateral wall of the nasopharynx, approximately at the level of the inferior nasal concha. It consists of a bony part and a cartilaginous part.

A portion of the tube (1/3) proximal to the middle ear is made of bone; this bony part is about 12 mm in length. It begins in the carotid wall of the tympanic cavity, below the septum canalis musculotubarii, and, gradually narrowing, ends at the angle of junction of the squama and the petrous portion of the temporal bone, its extremity presenting a jagged margin which serves for the attachment of the cartilaginous portion of the rest of the tube,[3] and this raises a tubal elevation, the torus tubarius, in the nasopharynx where it opens.

There are four muscles associated with the function of the Eustachian tube:

Product Description

This book, written by international experts, is a detailed guide to the Eustachian tube, with emphasis on those aspects of most relevance to the practitioner. 

The opening chapters document the clinical anatomy and provide essential information on physiology, with explanation of the new model of tubal mechanics. 

Diagnosis and therapy for the patulous Eustachian tube are then discussed, placing special emphasis on a novel conservative treatment regimen that has proven to be a breakthrough for patients with this clinical syndrome. 

A further extensive chapter examines overall function of the Eustachian tube, primarily from the middle ear surgeon’s viewpoint. 

Tuboplasty procedures, including laser tuboplasty, and tympanoplasty are described, and the implications of different middle ear pathologies for surgical treatment are explained. 

The previously unpublished treatment methods that are described in this book will be invaluable in ensuring the best possible clinical outcomes.
