Efficacy of Zeta palatopharyngoplasty in the management of obstructive sleep apnea

Abstract

Background: Due to obstructive sleep apnea (OSA), cardiovascular system and brain are affected resulting in OSA syndrome. Daytime sleepiness is seen in 80% cases. This can affect their work, quality of life and can be lead to accidents. It may also affect cognition,
concentration, memory, and mood and can lead to neurobehavioral dysfunction, depression and irritability.
Objective: To study the efficacy of zeta palatopharyngoplasty in the management of obstructive sleep apnea Methods: Hospital based prospective study was carried out among 30 cases of OSA. All cases were surgically managed using the Zeta palatopharyngoplasty. The outcome of surgery including complications was studied.
Results: Mean age was 45.1 years. Most of them belonged to 4th-5th decade. 26 (87%) were males. All subjective symptoms were relieved 100% postoperatively except day time fatigue which persisted in 30%. Polysomnography parameter of AHI showed success of surgical procedure. Postoperative respiratory distress index values predominantly belonged to category of 5-14 in 86% showing an improvement of 80.77% on average. Postoperatively oxygen saturation values improved drastically mostly falling in normal range of 80-90 seen in 60% and >90 seen in 30% with an improvement of 22.1% on average. Total snoring events showed an improvement of 88.9%. Postoperative FLP findings showed relief from these blocks as patients have undergone tailored multilevel surgical corrections. All were free from complications by six months. In categorization of OSA more number of patients was categorized as severe in 53.3% preoperatively. Postoperatively 11 (36.3%) have become normal and 19 (63.3%) have come down to mild category.
Conclusion: The Zeta palatopharyngoplasty has been found to be effective in the management of patients with OSA.
