ICD-10-CM Code for Unspecified Eustachian tube disorder, bilateral H69. 93.
Patulous Eustachian tube dysfunction is a disorder of the valve of the Eustachian tube that causes it to remain open. When this valve remains open, sound can travel from the nasal-sinus cavity to the ears, allowing you to hear your own voice or your own breathing too loudly, or even the sound of blood pumping.
The Eustachian tube is a small passageway that connects your throat to your middle ear. When you sneeze, swallow, or yawn, your Eustachian tubes open. This keeps air pressure and fluid from building up inside your ear.
Symptoms and Causes Common eustachian tube dysfunction symptoms include: Hearing problems. Tinnitus, or ringing in your ears. Clicking or popping sounds.

Summary. Patulous eustachian tube (PET) occurs when the eustachian tube remains open. You may not know you have it unless you are experiencing some red-flag symptoms. These the feeling that your ear is clogged, hearing your own voice in your ear, or experiencing a ringing sensation, a condition known as tinnitus.
The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx.
The Eustachian tube is located in the para-pharyngeal space and is closely linked to the infratemporal fossa. The Eustachian tube continues from the front wall of the middle ear to the sidewall of the nasopharynx, progressing along the posterior edge of the medial pterygoid plate.
And, because COVID-19 causes inflammation in the nose and nasopharynx (the upper part of the throat located behind the nose), the Eustachian tube (the tube that connects the nose and middle ear) may also become inflamed during the course of the infection and lead to middle ear congestion.
Oral decongestants are used in the treatment of eustachian tube dysfunction (ETD) and can help decrease peritubal edema provoked by allergies or URI. Oxymetazoline is an ingredient found in topical decongestants.
In most or perhaps all cases, symptoms of vertigo are caused by unilateral ETD or by a Eustachian tube obstruction due to ETD that is more severe on one side than on the other. The direction of gait can indicate which side is affected, as most patients stagger towards the direction of the obstructed side [2].
