[Postoperative inhalation treatment after paranasal sinus interventions. A placebo-controlled, double-blind and randomized study].

A placebo-controlled, double-blind study with Ems brine inhalations as postoperative treatment after endoscopic endonasal sinus surgery was conducted on 30 patients. After informed consent had been obtained, the patients were treated with either Ems brine or saline solution (200 ml) 3 times a day for 10 days. The parameters measured were rhinomanometry, X-ray films of the sinuses, endoscopy, saccharin clearance and a subjective evaluation by the physician and by the patient based on a visual analogue scale. The difficulty of choosing parameters for assessing the treatment was that comparable clinical studies and a single predictive parameter were not available. The bacteriological test and the saccharin clearance test were not significantly different between the two groups. Recovery, swelling, crusting, bleeding and signs of inflammation, opacity on sinus X-ray films, and nasal flow as measured by rhinomanometry were all significantly better in the group inhaling brine solution (P less than 0.05).
