Trans-tympanic Cartilage Chip Insertion for Intractable Patulous Eustachian Tube.

ABSTRACT:

Background and objectives

Patulous Eustachian tube (PET) causes troublesome autophony. We treated PET using tragal cartilage chip insertion to fill in the concavity within the tubal valve and evaluated the feasibility of this method.

Subjects and methods

This study used a prospective design. Eleven patients with PET disorder were included. Tragal cartilage chip insertion via a transcanal approach into the Eustachian tube (ET) was performed in 14 ears of those patients. They were followed-up for at least 12 months after surgery and were evaluated by symptom questionnaire scores.

Results

The average follow-up was 16.4 months. Thirteen of fourteen ears received immediate complete relief of autophony symptoms. Autophony symptoms at the last follow-up were as follows: four
