Background: Hyaluronic acid (HA) plays a significant role in tissue repair of mucosal surfaces and, consequently, in surgical injury remodelling of nasal mucosa.
Objective: To assess the effect of high-molecular-weight HA administered by aerosol on the morphofunctional recovery of ciliated cells damaged by surgical trauma.
Methods: A single-blind, prospective, randomized trial was carried out with 94 patients who were randomly assigned, after endoscopic turbinoplasty, either to treatment with nasal saline solution irrigation (control group, n = 47) or to treatment with nasal douches based on high concentration (9 mg) and high-molecular-weight sodium hyaluronate (active treatment group, n = 47).
Background: Insult from surgical trauma leads to a degeneration of the nasal epithelium, resulting in morphological-volumetric changes involving the entire cell or a specific cell component. Alterations in normal nasal mucosa were assessed by nasal cytology and other functional tests after either endoscopic turbinoplasty or laser-assisted turbinoplasty for reducing inferior turbinate enlargement.
Methods: A total of 150 patients with chronic nasal obstruction due to inferior turbinate hypertrophy were randomly assigned to undergo laser-assisted turbinoplasty or endoscopic turbinoplasty.
