Abstract
We performed submucosal autologous fat injections to the pharyngeal orifice of the eustachian tube for a case of patulous eustachian tube in which the symptoms did not improve with conservative treatment. As otitis media with effusion occurred postoperatively, an eardrum ventilation tube was placed. Although hearing ability did not improve, unpleasant subjective symptoms such as amplified volume of own voice and perceiving self-respiratory sounds disappeared. Although surgery is anticipated to improve symptoms in cases of patulous eustachian tube, it is important to deal with the recurrence of symptoms and complications such as otitis media with effusion. We investigated indications and appropriate procedures for surgery to treat patulous eustachian tube and report on our results together with a review of the literature.
