How to treat a patulous Eustachian tube

We would like to comment on the manuscript entitled "Endoscopic autologous cartilage injection for the patulous Eustachian tube" by Oh et al. [1]. This is an interesting study and excellent work. Although a patulous Eustachian tube (ET) is not usually seen in otorhinolaryngology clinics, it may cause aural fullness and autophony of the voice or breath sounds, negatively affecting the patient's quality of life. The relief of these symptoms is important. Although many scholars have proposed treatment methods, no ideal method has been developed due to the small sample size, short follow-up, and complications seen in the various studies.
