Multiple level pharyngeal surgery for obstructive sleep apnoea

Area of Science:

• Otolaryngology
• Sleep Medicine
• Surgical Innovation

Background:

• Obstructive sleep apnea (OSA) is a common condition with significant health implications.
• Moderate to severe OSA often requires advanced treatment options when conservative methods fail.
• Surgical interventions targeting multiple pharyngeal levels are being explored for complex cases.

Purpose of the Study:

• To evaluate the efficacy of multi-level pharyngeal surgery for moderate to severe obstructive sleep apnea (OSA).
• To assess surgical outcomes using objective measures like polysomnography and cephalometric analysis.
• To determine the impact of surgery on patient-reported outcomes such as daytime sleepiness.

Main Methods:

• A cohort of 13 patients with moderate to severe OSA, who failed non-surgical treatments, underwent multi-level surgery.
• Surgical procedures included uvulopharyngopalatoplasty, genioglossal advancement, and modified hyoid myotomy and suspension.
• Pre- and post-operative assessments included the Epworth Sleepiness Scale (ESS), cephalometric analysis, and polysomnography (sleep study) to measure the apnea-hypopnea index (AHI).

Main Results:

• 76.9% of patients achieved a >50% reduction in AHI, with post-operative AHI < 20.
• Cephalometric analysis revealed an average increase of 5.2 mm in posterior airway space.
• All patients showed improvement in ESS scores, averaging an 11.8-point reduction.
• Mean follow-up was 12.6 months.

Conclusions:

• Multi-level pharyngeal surgery demonstrates promising efficacy in treating moderate to severe obstructive sleep apnea (OSA).
• The surgical approach leads to significant objective improvements in airway patency and respiratory events.
• Patients report substantial reductions in daytime sleepiness, indicating improved quality of life.
