-
-
- In Patulous Eustachian Tube dysfunction, the eustachian tube abnormally
- remains open constantly. This results from reduced soft tissue mass around
- this tube. Symptoms of this disorder occur when the patient's head has been
- erect for several hours.
-
- Symptoms
-
- Symptoms of Patulous Eustachian Tube dysfunction include a stopped-up feeling
- in the ear, and their voice will sound unusually loud to them. They may hear
- a rushing or blowing sound on respiration without a loss of hearing.
-
- In persons with this disorder, the eardrum moves in and out while the
- patient is breathing though the nose with the mouth closed.
-
- Causes
-
- Patulous Eustachian Tube is caused by loss of soft tissue around the
- eustachian tube, and by a lack of strength in the muscle which provides
- tension to the eardrum (the m. tensor veli palatini).
-
- The condition is often associated with recent weight loss, and with a
- high concentration of estrogens in the blood due to pregnancy or medication.
- Other causes of P.E.T. dysfunction are neuromuscular disorders such as
- multiple sclerosis, poliomyelitis, Parkinson's disease and neurovascular
- accident. Adhesions and scarring of the pharyngeal recess and of the
- posterior lip of the pharyngeal opening of the eustachian tube can also
- result in the disorder.
-
- Affected Population
-
- Patulous Eustachian Tube is most prevalent in women who have had a
- significant recent weight loss, in pregnant women, and in men and women who
- have taken estrogens.
-
- Related Disorders
-
- Middle Ear Effusion is the chronic accumulation of thick fluid in the middle
- ear. Deafness, fullness and crackling noises in the ears can occur as a
- result of this disorder.
-
- Therapies: Standard
-
- Temporary relief for patients with Patulous Eustachian Tube can be obtained
- by lying down or bending forward with the head between the knees. Sniffing
- can also provide momentary relief.
-
- Therapies: Investigational
-
- Patulous Eustachian Tube dysfunction has been treated surgically by cutting
- the hook around which the tendon of the tensor veli palatini muscle passes
- (pterygoid hamulotomy) combined with transposition or transection of the
- tendon of this muscle. Good results have been obtained in approximately 70%
- of persons undergoing this procedure.
