Usefulness of snoreplasty in the treatment of simple snoring and mild obstructive sleep apnea/hypopnea syndrome – Preliminary report

Abstract The aim of the study: To assess the effectiveness of sodium tetradecyl sulfate injection in the region of the soft palate to treat primary snoring and mild obstructive sleep apnea/hypopnea syndrome. Sodium tetradecyl sulfate, a preparation belonging to detergents, widely applied in Poland to treat varices by the method of compressive sclerotherapy was used in the study. Material and methods The procedure of injected snoreplasty was performed in 21 patients, who were diagnosed with primary snoring or mild obstructive sleep apnea/hypopnea syndrome, based on subjective examination and polysomnography. Injected snoreplasty involves administration of sodium tetradecyl sulfate in the form of Fibrovein 1% or 3% preparation in the volume of 2 ml, in the region of the soft palate. Injection of the preparation in the area of the soft palate induces the development of aseptic inflammation, which creates a scar which stiffens the soft palate and makes the tissues of this region less susceptible to vibrations. Results The patients after injected snoreplasty reported a significant decrease in the intensity of snoring. The markedly shortened total time of snoring was found in check-up polysomnography performed six months after the procedure. Conclusions Injected snoreplasty is an effective procedure, especially, in patients manifesting persistent snoring. It is not indicated in the treatment of obstructive apneas during sleep. The advantages of this method are: minimal invasiveness, the low number of complications and slight pain.
