Endoscopic Embolization

This procedure can use materials such as silicone rubber plugs or autologous cartilage. Typically, under the guidance of a nasal endoscope, the nasal pharyngeal opening of the Eustachian tube is accessed transnasally to assess its morphology, and then an embolic body is created and placed, or a cavity is created submucosally to reduce the patency of the opening, while taking care to preserve necessary ventilation. Postoperative monitoring includes ear pressure, hearing, and bleeding, with the goal of alleviating autophony and the sense of echo. The above is general health information and not medical advice; the specific plan is subject to specialist evaluation and the hospital's protocol.
