The facts are in, based on a review of 56 published studies, the NightLase snoring treatment reduced snoring intensity and improved sleep quality.
A meta-analysis on Er:YAG laser effectiveness for snoring, published in the Journal of Clinical Medicine in 2025, reviewed 56 studies from 2015-2025, the largest to date. The results showed:
- The Er:YAG based treatment, called NightLase significantly reduced snoring intensity and improved subjective sleep quality.
- High patient satisfaction with the procedure.
- Safe, with only brief minor side effects.
- Therapeutic effects lasted 12-24 months in most patients.
Best results were seen in non-smoking patients with normal body mass index, and baseline apnea-hypopnea index scores (AHI=5-30 events/hour). This is consistent with mild to moderate Obstructive Sleep Apnea. AHI decreased by 7.2.
The conditions enumerated above decrease treatment effectiveness. Note that nasal patency is a significant contributing factor to non-responsiveness or decreased effectiveness.
The authors compared the NightLase with other commonly used snoring treatment modalities:
These results demonstrate the need for patient selection and underline the indications for incorporating additional measures (weight loss, dietary recommendations, treatment of allergic rhinitis, treatment of nasal valve collapse) to enhance and promote effective treatment results.
