Patulous ETD is a rare condition where the eustachian tubes remain open regularly. In its usual closed position, the eustachian tube protects the inner ear from infection and unbalanced air pressure. When it remains open, the inner ear is susceptible to mucus clogs, further damaging the structure and other inner-ear tissues.
