Eustachian Tube Scores Effective Diagnostic Tools for Chronic Obstructive Eustachian Tube Dysfunction

How effective is the Eustachian tube score (ETS) for the diagnosis of chronic obstructive Eustachian tube dysfunction (COETD)?

Background: Obstructive dysfunction of the Eustachian tube (ET) is one of the underlying possible causes of pressure sensations in the ear, fluctuating hearing loss, or ringing in the ears. It may also result in different middle ear pathologies. There is no current gold standard for COETD diagnosis. TMM is a semiobjective method to record ET patency.

Study design: Combined, prospective, retrospective clinical study of 215 healthy subjects at a tertiary referral center between August and October 2011, and 171 patients with COETD.

Setting: Department of Otorhinolaryngology–Head and Neck Surgery, Bielefeld Clinical Center, Academic Teaching Hospital, University of Munster, Bielefeld, Germany.
