They inserted a soft catheter into the tympanal orifice and fixed it with bone wax.

Modifications of the nasopharyngeal anatomy by surgical procedures, such as adenoidectomy or tonsillectomy with postoperative scarring, can also be a cause of a pET [150]. Likewise, scarring after irradiation of the cranium can also result in a closing failure of the Eustachian tube, which can be shown using tubal manometry in about 50 % of the patients [22]. After a retrospective analysis of 16 patients with a pET, Todd and Saunders [199] postulated a correlation between the frequency of chronic suppurative otitis media during childhood and the occurrence of a pET in adults.

Neither oedema-inducing drugs [130], paratubal injections at the pharyngeal orifice [148], ventilation tubes in the ear drum [102], surgical manipulations on the tensor veli palatini muscle [206], nor a complete obstruction of the Eustachian tube [13, 31] could show more than temporary effects on the symptoms.
