Thirty HydroxylVent tubes were implanted in twenty-seven patients. The chief Indications were unresolving eustachian tube dysfunction, with either collapse or perforation of the tympanic membrane. Every patient had undergone a lengthy course of treatment with conventional ventilation tubes. Twenty ears (66%) showed good results, with prolonged ventilation and restoration of middle ear function. Two tubes appeared to be open, with the development of a pinpoint perforation of the drum. Eight tubes occluded as a result of displacement of the tube, middle ear pathology, or debris. Indications and techniques of management are discussed, along with an analysis of complications.
