Abnormal eustachian tube function has been a major problem in improving hearing with middle ear surgery. In 13 patients, a newly developed gold tube conductor was placed in the eustachian tube via the middle ear cavity. Patients were examined 2-50 months postoperatively, at which time middle ear aeration was found to be significantly improved in 11 of the cases.
