Patulous Eustachian tube. Diagnostic evaluation by sonotubometry
Acta Oto-Laryngologica
|November 1, 1978
Summary
Sonotubometry clearly diagnosed patulous Eustachian tube in all patients. This method aids in diagnosing abnormal Eustachian tube patency and monitoring treatment effectiveness.
Area of Science:
- Otolaryngology
- Medical Diagnostics
Background:
- Patulous Eustachian tube (PET) is a condition where the Eustachian tube remains abnormally open.
- Symptoms can be debilitating, affecting patients' quality of life.
Purpose of the Study:
- To analyze symptoms of pathologically patent Eustachian tubes.
- To evaluate sonotubometry as a diagnostic tool for patulous Eustachian tube.
Main Methods:
- Twenty-five patients (31 ears) with pathologically patent Eustachian tubes were studied.
- Sonotubometry was used to examine all ears.
- Impedance variations during respiration and air pressure equalization were also assessed in some cases.
Main Results:
- Sonotubometry clearly identified the patulous Eustachian tube in all examined ears.
- Two distinct opening patterns were identified for the patulous tube.
- Impedance variations during respiration were recorded in most ears.
Conclusions:
- Sonotubometry is a valuable tool for diagnosing abnormal Eustachian tube patency.
- This method aids in monitoring treatment outcomes for patulous Eustachian tube.
