[The correction of Eustachiantube dysfunction after microscopic rhinological surgical interventions by prolonged transtubal drainage].

The objective of the present study was to analyse the results of he treatment of Eustachian tube dysfunction by means of prolonged transtubal drainage of the tube lumen using a polyethylene catheter introduced immediately after the completion of the rhinosurgical intervention for the targeted delivery of pharmaceutical products. Eighty four patients with Eustachian tube dysfunction and impairment of hearing had a thin catheter introduced in the tube lumen for 7-14 days after various rhinosurgical interventions. We estimated the efficacy of the local treatment following rhinosurgery with the subsequent prolonged administration of pharmaceutical products through the intratubal drainage system.
