P neumolabyrinth is a condition in which the vestibule and/or cochlea is filled with air. Eustachian tube insufflation (ETI) is a type of treatment for recurrent serous otitis media that is still popular in Europe. It exploits the anti-inflammatory and mucolytic effects of thermal waters containing sulfur and bromo-iodine gas. To our knowledge, no case of a pneumolabyrinth due to barotrauma pro...

The middle ear is the part of the ear that is enclosed behind the eardrum. A tiny tube, called the eustachian tube, drains any fluids from the middle ear into the throat. Colds and episodes of allergic runny nose, due to airborne allergens or allergies to cow’s milk or other foods, block this eustachian tube with mucus and inflammation. When this tiny mucous-membrane-lined canal is closed off, ...

Direct middle ear (ME) pressure measurements during 24 h and tubal function tests were performed on 11 subjects with the clinical diagnosis patulous Eustachian tube (PET). The pressure was recorded from the ME via a perforation in the tympanic membrane. The method used has previously been reported in a study on subjects with normal ME function and no symptoms of PET: a normal group. Results fro...

Over a period of 4 years, 420 patients were observed with fullness in the ear, episodic vertigo, fluctuating hearing, and tinnitus. Of them, 182 patients showed normal hearing levels, a mild eustachian tube dysfunction, normal SP/AP ratios, mydriasis on the side of the affected ear, and a functional disorder of the upper cervical spine. These patients responded to conservative management, parti...

In this chapter, I describe the available diagnostic procedures and tests of the structure and function of the Eustachian tube system. In other chapters in this text, I briefly refer to many of these procedures in describing certain aspects of the anatomy, physiology, and pathophysiology of Eustachian tube function and dysfunction and the tubal system’s role in pathogenesis of otitis media and ...

Title: Meniere’s disease with patulous eustachian tubes Background: Meniere’s disease (MD) is considered to be a multifactorial disease. Although there are some previous reports on the relationship between MD and stenotic eustachian tube (ET), there are a few reports evaluating MD and patulous ET. The study aimed to investigate whether MD would have patulous ET or not. Methods and Findings: Son...

Introduction The eustachian tube is one of the key structures responsible for the functional balance of the middle ear. Some clinical conditions associated with tubal malfunction can cause extremely unpleasant symptoms. These symptoms could be triggered by acute loss of weight, for example, after bariatric surgery. Objective To evaluate the frequency and intensity of auditory tube dysfunction s...

OBJECTIVES/HYPOTHESIS To propose a definitive standard grading scale in the assessment of adenoid tissue in relation to size, position, and proximity to surrounding anatomic structures. This will allow for better clinical communications among practitioners when treating this pathology, a better understanding of its relationship and how it effects neighboring structures (eustachian tube and choa...
