The Results of Uvulopalatopharyngoplasty in Patients with Moderate Obstructive Sleep Apnea Syndrome Having Cardiac Arrhythmias

Objectives: The goal of this practice was to explore whether the changes in arrhythmias after uvulopalatopharyngoplasty (UPPP) in patients with moderate obstructive sleep apnea syndrome (OSAS) who continued cardiac arrhythmias despite the use of antiarrhythmic drugs and those who could not tolerate the continuous positive airway pressure (CPAP) device. In addition, we evaluated the correlation between arrhythmias before and after UPPP. Methods: This retrospective study included patients who have OSAS and cardiac arrhythmias, between 2008 - 2017 by the cardiology clinic and consulted by the ear, nose, and throat (ENT) clinic. Thirty eight patients were selected and underwent UPPP operation. The rhythm Holter follow-ups of the patients in the 1st month before UPPP (pre-UPPP) and after UPPP (post-UPPP) 6th month were performed. The recordings were transferred to the computer and evaluated with the Holter program, then visually examined and the parasitic regions were excluded. Sinus bradycardia (SB), atrioventricular block (AVB), atrial premature beat (APB), supraventricular tachycardia (SVT), and ventricular extrasystole (VES) parameters were recorded for arrhythmia. Results: Statistically significant differences were observed in the changes in SB, AVB, APB, SVT and VE arrhythmia values in pre-UPPP and post-UPPP periods. Also, in one case the values of arrhythmia in the pre-UPPP period had a positive correlation with the values of the same arrhythmia in the post-UPPP period (P < 0.001). Conclusions: In this study, new information about the effects of UPPP which is one of OSAS treatment methods on cardiac arrhythmias is presented. According to our results, UPPP reduces the rate of SB, AVB, APB, SVT and VES arrhythmias in OSAS patients.
