“…Correlations between anatomy and disease were also reported regarding the tubotympanic angle. In studies by Nemade et al ( 18 ) and by Elibol and Baran ( 12 ), the value of the tubotympanic angle was higher in patients with chronic otitis. The influence of the ET length should also be considered.…”

“…Aksoy et al ( 15 ) demonstrated a relationship between a reduced auditory tube angle and the occurrence of chronic ear diseases. Elibol and Baran ( 12 ) and Yang et al ( 16 ) found a relationship between a chronic ear disease and a narrower auditory tube angle. Masita et al ( 17 ) found that the auditory tube angle was lowest in patients with cholesteatoma, followed by those with chronic otitis media mesotympanalis and highest in those without middle ear diseases.…”

“…Anatomical factors include the auditory tube angle, the tubotympanic angle, and Körner's septum. Elibol and Baran ( 12 ) investigated a relationship between chronic otitis media and the auditory tube angle, that is, the angle between the line of the tympanic and pharyngeal orifices of the ET and Reid's plane and the tubotympanic angle. The tubotympanic angle is the angle between the line originating from the tympanic opening the ET and the longitudinal axis originating from the center of the external auditory canal.…”

“…The tubotympanic angle is the angle between the line originating from the tympanic opening the ET and the longitudinal axis originating from the center of the external auditory canal. There is evidence that changes in the auditory tube angle and the tubotympanic angle may reduce the protective functions of the ET and lead to changes in the ventilation of the middle ear and thus to an increased risk of developing chronic middle ear diseases ( 12 ). Regarding the auditory tube angle, the correlation with chronic middle ear disease is ambiguously described.…”

The Rate of Eustachian Tube Dysfunction in Adult Patients With Chronic Inflammatory Middle Ear Disease Is Low

et al. 2023

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. Intervention(s): 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 Measure(s): 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.
