Eustachian Tube Evaluation in Patients With Obstructive Sleep Apnea Syndrome


Eustachian Tube Evaluation in Patients With Obstructive Sleep Apnea Syndrome

Giuseppe Magliulo et al. Acta Otolaryngol. .


Objectives: Investigate the presence of Eustachian Tube Dysfunction (ETD) in Obstructive sleep apnea (OSA) patients. Correlate the ET function and the severity of the sleep apnea syndrome. Correlate nasal resistance and nasal mucociliary clearance with the onset of ETD in these patients.

Materials and methods: Forty patients affected by OSA were enrolled in our clinical prospective study. Thirty patients were also investigated as a control group. All of the analyzed subjects underwent ENT examination, anterior rhinomanometry and test for mucociliary transport time. To evaluate Eustachian tube function the Eustachian tube score-7 (ETS-7) were employed.

Results: Twenty percent of the patients with a diagnosis of OSA had a diagnosis of ETD (ETS-7 ≤ 7) with a statistical difference with control group (p = .03). No differences regarding ETD in OSA sub-groups were found.

Conclusion: This study showed that ET blockage or delayed openings were found in most adult patients with OSA when evaluated by a sensible score as the ETS-7. Our data suggest that an evaluation of the Eustachian tube function should be performed in patients suffering from obstructive sleep apnea syndrome.

Keywords: Eustachian tube dysfunction; Obstructive sleep apnea; anterior rhinomanometry; mucociliary transport time.
