The aim of this study was to assess the long-term outcomes of nonablative Er:YAG laser treatment for snoring. 

Background data:

Nonablative Er:YAG laser treatment has been shown to improve subjective quality of sleep without serious adverse effects, but long-term data are lacking. 

Materials and methods:

Twenty-four patients with snoring problems due to soft palate hypertrophy were treated with three treatment procedures with Er:YAG laser performed at 2-week intervals. Subjective (questionnaires) and objective (polygraph) outcome measures were assessed at baseline, 3 months, and 4 years after the final laser treatment. 


Twenty patients returned for the 4 years follow-up. The significant improvement in subjective sleep outcomes observed 3 months after Er:YAG laser treatment was still significant 4 years after treatment. No significant improvement or deterioration in objective polygraph outcome measures was observed during the 4 years of follow-up in our study. No side effects of laser treatment were observed. 


The Er:YAG laser treatment presents a safe and well-tolerated snoring treatment alternative for patients with airway obstruction in the oropharynx with improvement in subjective sleep outcomes lasting up to 4 years.
