Obstructive sleep apnea: variations in surgical management

Area of Science:

• Otolaryngology
• Sleep Medicine
• Surgical Innovation

Background:

• Obstructive sleep apnea (OSA) significantly impacts patient health and quality of life.
• Surgical interventions aim to improve airway patency in OSA patients.
• Submucous resection and palatopharyngoplasty (PPP) are surgical options for OSA.

Purpose of the Study:

• To evaluate the efficacy of submucous resection alone versus combined with palatopharyngoplasty (PPP) for obstructive sleep apnea (OSA).
• To assess the effectiveness of supplemental tongue retaining devices (TRD) in patients with persistent OSA symptoms post-surgery.

Main Methods:

• Forty OSA patients underwent surgical treatment: submucous resection alone (23 patients) or submucous resection with PPP (17 patients).
• Sleep evaluations were performed pre- and post-surgery to assess apnea index reduction.
• Tongue retaining devices (TRD) were used as a secondary treatment for non-responders.

Main Results:

• Submucous resection alone achieved a 57% success rate. Supplemental TRD improved outcomes in 50% of non-responders in this group.
• Submucous resection combined with PPP demonstrated an 82% success rate.
• Four out of seven patients (57%) who received TRD after combined surgery showed marked improvement.

Conclusions:

• Palatopharyngoplasty (PPP) combined with submucous resection offers a higher success rate for obstructive sleep apnea (OSA) treatment.
• Tongue retaining devices (TRD) can be an effective adjunctive therapy for OSA patients who do not fully respond to initial surgical procedures.
