Multilevel Surgery in Obstructive Sleep Apnoea

Background/Aims: Obstructive Sleep Apnoea (OSA) is a common public health problem withmultisystem consequences. Surgery for OSA is increasingly being recognized as an effectivetreatment modality, especially in patients where CPAP therapy has failed or is not viable. OSAcan be due to multilevel obstructions; hence the focus is on multilevel surgical correction. Thisstudy illustrates three common levels of upper airway obstruction and their surgical correction.Materials and Methods: Three patients presented with three different levels of airwayobstruction leading to OSA and their surgical management is displayed along with theirclinical outcomes. Surgery includes Barbed Palatopharyngoplasty for collapsing velum andoropharyngeal walls, Endoscopic midline Glossectomy for tongue base obstruction, andEndoscopic Epiglottoplasty for epiglottis collapse.Results: Primary outcomes: the difference between pre and post-operative AHI, RDI index,and ESS. Secondary outcomes: OSA symptoms such as snoring and daytime somnolence andquality of life.Conclusions: This study highlights the clinical effectiveness, safety, and cost-effectiveness ofmultilevel upper airway surgery for OSA.
