Abstract
Patulous eustachian tube (PET) is often misdiagnosed due to the
difficulties to perform the tests designed to evaluate the function of
the eustachian tube (ET). We describe a simple but very efficient test
that can be performed in the clinic or by the patient himself at home to
diagnose this problem by nose irrigation of physiological serum. Key
points: Patulous eustachian tube, autophonia, deafness, tinnitus,
physiological serum, diagnosis. Key Points: Question: Patulous
eustachian tube sometimes doesn´t relieves lying in a lordotic position.
Additional problems: Ussualy the problem is intermittent and diagnostic
criteria include oclusion of the eustachian tube. Test design: We
designed a test to occlude the eustachian tube by the patient himself at
home with physiological serum. Findings: The occlusion with serum is
effective in almost all the patients. Meaning: Occlusion with
physiological serum is useful in the diagnosis and treatment of patulous
eustachian tube.
