Nebulized hyaluronic acid and xylitol based solution after turbinate radiofrequency ablation. A triple blind randomized multicentric clinical trial.

OBJECTIVE

This prospective, triple blind randomized clinical trial aims to specifically evaluate the effect of Aluneb® (hyaluronic acid plus xilitol) in the postoperative treatment of inferior turbinate radiofrequency in adults compared to nebulized isotonic saline.

METHODS

Adults undergoing radiofrequency turbinate ablation were included. Treatment group received Aluneb® (hyaluronic acid plus xylitol) while the control group received nebulized isotonic saline for two months after treatment. Participants were studied the week before surgery (visit 0), and at 7, 15, 30 and 60 days after surgery. At all visits, participants underwent physical examination, rhinomanometry, SNOT-22, and visual analogue scale (VAS) of symptoms.

RESULTS

34 participants were recruited. Crusts (endoscopy) were less in the Aluneb® hyaluronic acid plus xylitol group. Nasal crusting, epistaxis and nasal obstruction VAS were statistically significant lower. VAS for Rhinorrea, halitosis, cacosmia and pain and nasal resistance obtained lower self-reported values in the hyaluronic acid plus xilitol group, but these differences were not statistically significant.

CONCLUSIONS

Hyaluronic acid plus xilitol demonstrated promise in improving postoperative outcomes, future studies with larger sample sizes and different surgical techniques are encouraged.
