    Abstract:
    BACKGROUND: To determine the effect of intranasal sodium hyaluronate on mucociliary clearance time following functional endoscopic sinus surgery in patients with nasal polyposis. STUDY DESIGN: Randomized, controlled, blinded study. METHODS: Thirty-six patients with grade II nasal polyposis undergoing functional endoscopic sinus surgery received intranasal sodium hyaluronate 9 mg twice daily or saline for 30 days commencing on the second day after surgery. Ciliary mucous transport time was assessed using charcoal powder and saccharin administered during rhinoscopy. Other outcomes included changes in symptoms, endoscopic appearance of the nasal mucosa, and tolerability. RESULTS: Patients receiving sodium hyaluronate had a significantly faster mucociliary clearance time at 1 month compared with controls (14.3 +/- 2.5 vs. 23.6 +/- 3.3 minutes; p = 0.000). Furthermore, sodium hyaluronate recipients experienced a lower incidence of rhinorrhea, less nasal obstruction and a lower incidence of exudate on endoscopy than control subjects at 1 month (all p < 0.05). Sodium hyaluronate was well tolerated in patients following functional endoscopic sinus surgery. CONCLUSION: The use of intranasal sodium hyaluronate in patients undergoing functional endoscopic sinus surgery for nasal polyposis augmented the improvement in mucociliary clearance observed following this procedure and improved several clinical and endoscopic parameters. These data provide encouraging evidence of the beneficial effects of sodium hyaluronate in the care of patients undergoing functional endoscopic sinus surgery with which to continue the development of the product for this indication.
