Summary
Radiofrequency tongue base reduction is a feasible and safe treatment for obstructive sleep apnea syndrome (OSAS). This procedure effectively reduced snoring, sleepiness, and improved oxygen saturation in patients with OSAS.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Minimally Invasive Surgery
Background:
- Obstructive sleep apnea syndrome (OSAS) is a common disorder characterized by repeated upper airway collapse during sleep.
- Tongue base obstruction is a significant contributor to OSAS, necessitating effective treatment strategies.
Purpose of the Study:
- To evaluate the feasibility, safety, and efficacy of radiofrequency tongue base reduction via a cervical approach for treating moderate to severe OSAS.
- To assess the impact of the procedure on snoring, daytime sleepiness, and polysomnographic parameters.
Main Methods:
- A prospective cohort study included 10 patients with OSAS and tongue base obstruction.
- Radiofrequency energy was delivered to the tongue base through a cervical approach under fluoroscopic guidance.
- Outcomes measured included adverse events, snoring severity, Epworth sleepiness scores, and polysomnography.
Main Results:
- The procedure was feasible and safe, with no tongue palsy or infection reported.
- Significant reductions were observed in snoring (P = .017), daytime sleepiness (P = .011), and respiratory disturbance index (P = .016).
- Mean minimal oxygen saturation significantly increased (P = .003), indicating improved respiratory function.
Conclusions:
- Radiofrequency tongue base reduction through a cervical approach is a viable and safe option for OSAS treatment.
- Fluoroscopic guidance facilitates precise electrode placement for optimal therapeutic effect.
- While effective in most patients, further research is needed to optimize energy delivery and lesion site selection for enhanced efficacy, particularly in less severe OSAS cases.
