Endoscopic hydroxyapatite augmentation for patulous eustachian tube

Abstract

Endoscopic hydroxyapatite injection of the Eustachian tube is a minimally invasive procedure that provided significant or complete relief of autophony and ear fullness in 57% to 63% of sides treated. The procedure is well tolerated and can be performed safely under endoscopic visualization. Hydroxyapatite injection may be a satisfactory alternative to more invasive treatments for PET.
