The Eustachian tube is a canal from the tympanic cavity to nasopharynx that responsible for aeration, drainage, and pressure equalization of middle ear. Partial or complete blockage can trigger severe ear disease. We evaluated pathologic changes obstruction (ETO) in 15 temporal bones cats with bilateral ETO bone collection at University Minnesota Medical School Otopathology Laboratory. samples ...

General practitioners generate many clinical questions during consultations. 2 However, when they seek answers to these queries they tend to rely on colleagues and “desk top” references rather than searching the literature themselves. ATTRACT was created in 1997 to provide rapid, evidence based summaries to clinical queries. All general practitioners in Gwent were invited to send their clinical...

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, ...

OBJECTIVE To study the role of eustachian tube function in the development of recurrent otitis media with effusion (OME) in children treated with tympanostomy tubes for OME. DESIGN Prospective cohort study. SETTING Three academic and general hospitals. PATIENTS Children aged 2 to 7 years with a first clinical episode of OME that persisted for at least 3 months; 136 (81%) of 168 eligible c...

UNLABELLED Abnormalities in craniofacial morphology are associated with Eustachian tube dysfunction and otitis media with effusion (OME). AIM to evaluate the relationship between facial pattern and craniofacial growth direction, and OME in children with enlarged tonsils and adenoids (ETA). METHODS Clinical prospective survey in 79 children (41 male and 38 female), ranging from 4 to 10 years...

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...

Eustachian tube maintains middle ear pressure equal to that of atmospheric pressure and its functions is deranged due to various nasal, nasopharyngeal and palatal causes. Nasal polypi cause post nasal drip which is considered to cause Eustachian tube dysfunction. The present cross sectional study comprises of a total of 39 patients of Antrochoanal polyp with the aim to see the effect of antroch...

Otitis media with effusion (OME) is one of the most common causes of hearing loss (HL) in children. It has been reported that several factors such as eustachian tube dysfunction, insufficiencies in the aeration of the mastoid cells, allergies, immunity, and infections play an important role in the etiology of the disease. Little is known about the role of Helicobacter pylori (H. pylori) in extr...
