Adult obstructive sleep apnea treated with tonsillectomy: a randomized controlled clinical trial.

Area of Science:

• Otolaryngology
• Sleep Medicine
• Surgical Oncology

Background:

• Continuous positive airway pressure (CPAP) is the standard treatment for adult obstructive sleep apnea (OSA).
• Patient adherence to CPAP therapy is often suboptimal.
• Tonsillectomy is a surgical option for selected OSA patients.

Purpose of the Study:

• To compare the effectiveness of tonsillectomy versus lifestyle counseling for treating adult OSA.
• To evaluate changes in OSA severity after tonsillectomy or lifestyle counseling.

Main Methods:

• A randomized controlled trial involving 29 adult patients with mild to moderate OSA and BMI ≤ 35.
• Participants were assigned to either lifestyle counseling (n=17) or tonsillectomy (n=12).
• Polysomnography was conducted at baseline and one year to measure the apnea-hypopnea index (AHI).

Main Results:

• The tonsillectomy group experienced a significant reduction in AHI, improving OSA severity from moderate to mild.
• The lifestyle counseling group showed no significant change in AHI or OSA severity.
• Tonsillectomy demonstrated a statistically and clinically significant improvement in OSA metrics.

Conclusions:

• Tonsillectomy is an effective treatment for selected adult patients with mild to moderate OSA and limited obesity.
• Tonsillectomy serves as a viable alternative for patients non-adherent to conservative OSA treatments.
• These findings support personalized OSA treatment strategies for non-severe cases.
