Abstract
Aim: To evaluate the utility of ApneaGraph® AG 200 in diagnosing Obstructive Sleep Apnoea (OSA) as compared to Polysomnography, localization of the site of upper airway obstruction, and the success rate of surgery. Methods: A prospective study was conducted including fifteen patients of OSA undergoing surgical treatment. All patients underwent sequential overnight ApneaGraph (AG) and Polysomnogram (PSG) before and after 3 months following surgery. The preoperative and post-operative Apnoea-Hypopnoea Index (AHI) values were compared between AG and PSG. The success of surgery was defined as mean reduction in AHI by ≥ 50% and post-operative AHI < 20. Results: The mean preoperative AHI using PSG was 53.7 and using AG was 44.9 (r = 0.83, p = 0.0001). All patients underwent AG-directed site-specific surgery. The mean postoperative AHI using PSG was 15.3 and using AG was 13.8 (r = 0.67, p = 0.0062). There was significant improvement in AHI post-surgery (p < 0.05, AG & PSG). The surgical success was achieved in 93.3%. The median follow-up was 14 months. Conclusion: ApneaGraph is a reliable alternative to PSG to diagnose OSA with an added advantage to localize the site of obstruction, yielding good surgical outcomes.
