    Abstract:
    OBJECTIVE: To assess the rate of dilatory (chronic obstructive) eustachian tube dysfunction (ETD) in adult patients scheduled for surgery for chronic inflammatory middle ear disease. PATIENTS: We included adult patients with chronic inflammatory middle ear disease (chronic suppurative otitis media, adhesive otitis media [middle ear atelectasis], cholesteatoma). We excluded patients with pathologies that do not stem from ETD (e.g., noninflammatory chronic middle ear disease [e.g., otosclerosis], tumors, solely external auditory canal conditions), patients scheduled for implantable electronic hearing devices independent of disease, patients with otitis media with effusion and scheduled paracentesis or ventilation tubes only, patients with previous radiotherapy or previous balloon eustachian tuboplasty, and children and patients unable to complete questionnaires. INTERVENTIONS: We evaluated ETD with Valsalva maneuver and in case of negative or unclear Valsalva with the eustachian tube score (ETS). A negative Valsalva maneuver and an ETS score of 5 or lower were used to define dilatory (chronic obstructive) ETD. MAIN OUTCOME MEASURES: Rate of ETD in the included patients. RESULTS: From a total of 482 consecutive patients, 350 patients had positive Valsalva maneuver or ETS score higher than 5. From the 193 patients with negative or unclear Valsalva maneuver, 77 patients had an ETS score of 5 or lower, and 55 rejected further diagnostics with ETS. CONCLUSIONS: Based on a large cohort of adult patients with chronic inflammatory middle ear disease scheduled for middle ear surgery, the majority (82%) seems to have no dilatory (chronic obstructive) ETD that can be detected with current routine clinical methods and tubomanometry. Common pathophysiological explanations should be questioned critically, especially in the context of communication with patients.
