Endoscopic Embolization

Intervention can be considered after specialist evaluation when patulous Eustachian tube causes long-term autophony, a sense of echo, ear fullness, etc., and postural adjustments or conservative treatments (such as fluid replacement, nasal medications) are ineffective. The decision focuses on the severity and duration of symptoms, endoscopic and tympanometry results, previous treatment responses, the condition of the nasopharynx and middle ear, and the availability of materials and access routes.
