The comparison of multilevel surgery (hyoid myotomy and suspension with uvulopalatopharyngoplasty) with CPAP in moderate to severe OSAS patients

The comparison of multilevel surgery (hyoid myotomy and suspension with uvulopalatopharyngoplasty) with CPAP in moderate to severe OSAS patients:

Abstract



Purpose

The study aimed to determine the efficacy of multilevel surgery (hyoid myotomy and suspension with uvulopalatopharyngoplasty) and continuous positive airway pressure (CPAP) for the treatment of moderate to severe obstructive sleep apnea syndrome (OSAS) and to clarify whether our surgical protocol could be as effective as CPAP.




Methods

We conducted a case series study comparing the effects of multilevel surgery and CPAP in the same subjects to minimize the influence of confounding factors. Fifteen subjects were enrolled with a pretreatment apnea–hypopnea index (AHI) ≥ 15.




Results

Both CPAP and multilevel surgery could improve the AHI and oxygen desaturation index (ODI). The median AHI for baseline, CPAP and surgery were 38.9, 1.2 and 12.6, respectively (p < 0.001). The medina ODI for baseline, CPAP and surgery were 34.8, 0.9 and 7.2, respectively (p < 0.001). However, the results indicated CPAP as the more efficacious treatment modality compared with multilevel surgery. Moreover, CPAP not only decreased N1 sleep but also had beneficial effects on blood pressure control, whereas multilevel surgery did not have any significant difference.




Conclusion

CPAP is efficacious in improving OSAS severity, oxygen desaturation, sleep stage, and blood pressure control; while hyoid myotomy and suspension with uvulopalatopharyngoplasty are only efficacious in improving OSAS severity and oxygen desaturation. This study suggested that CPAP is the first choice when considering treatment of OSAS, especially in patients with hypertension or other cardiovascular diseases.
