Background
Nasal valve disorders frequently give rise to nasal obstruction. Dermal fillers could be used in the internal valve area to generate valve widening. The goal of this study was to report our "liquid spreader" procedure consisting in the injection of hyaluronic acid (HA) at the internal nasal valve in patients complaining of nasal obstruction.
Methods
The procedure described in this paper is suitable for patients with unilateral or bilateral nasal obstruction related to architectural features resulting in narrowing of the internal nasal valve. HA is injected along the internal valve from a single entry point located at the anterior part of the internal valve, thus creating a volume which will induce nasal valve widening. Rhinomanometries and visual analog scales (VAS) regarding nasal obstruction were collected before and after the procedure.
Results
Sixteen patients were enrolled (7 females). Mean age was 44 years (min=24 y-o, max=65 y-o). Thirteen presented nasal valve narrowing without septal deviation while 3 patients had high septal deviation. Before injection, mean nasal resistances were 3.4±5.6 sPa/mL (min=0.55, max=19.8). One month after injection, mean nasal resistances were 0.38±0.26 sPa/mL (min = 0.20, max = 0.85). The difference was statistically significant (p=0.049). VAS scores were improved with a trend back to baseline after 12 months.
Conclusions
The liquid spreader is a useful procedure that can be combined with non-surgical esthetic rhinoplasties.
