A PROSPECTIVE RANDOMIZED STUDY TO ASSESS THE EFFICACY OF POST- OPERATIVE NASAL MEDICATION AFTER ENDONASAL SURGERY Paul D.R.. Spragggs etal. The Journal of Laryngology and Otology July 1995, Vol. 109, pp Treatment Groups.Alkaline nasal douche (n = 19).Betnosol drops (n = 17).0.5% Eplidrine drops (n = 20).Control (n= 19)

Outcome Nasal stuffiness as measured on a visual analogue scale

Analysis Mann whitney U. Test Glass rank biserial correlation Significant ( P<0.05) differences were found at all time intervals

Conclusion The use of these treatments should be encouraged to both improve the sensation of nasal patency and also aid clearance of debris from the nasal fossae.

Mean Visual Analogue Scores (VAS) and Standard Deviations (SD) for each group.
