Purpose: Different authors have reported that aging could be associated with changes in obstructive sleep apnea (OSA) related parameters (apnea/hypopnea index, SpO 2 , reduction of daytime sleepiness, etc.), type of sleep and pattern of collapse. Regarding OSA severity in elderly patients, it is commonly believed that the AHI score tends to increase with aging., Methods: In this paper, we reviewed the literature regarding the studies which compared older (> 65 years old) and young (< 65 years old) OSA patients regarding the effect of aging on daytime sleepiness (ESS evaluation) and OSA severity (AHI evaluation). A meta-analysis to evaluate the effect of age on daytime sleepiness and OSAS severity was also performed to corroborate previously reported experience., Results: Meta-analysis showed no statistical (p = 0.8) differences regarding AHI differences emerged from the comparison of the two groups of patients. Elderly patients (> 65 years old) showed less daytime sleepiness, showing a statistical difference in the meta-analysis of data (p = 0.004) CONCLUSION: Although a direct correlation between aging and AHI values would seem to be present, no significant differences in baseline AHI between young (< 65-years-old) and elderly (> 65-years-old) patients emerged in this meta-analysis study. The effects of OSAS on daytime sleepiness seem to be much more prominent in young or middle-aged patients than in elderly patients.

Obstructive Sleep Apnea (OSA) syndrome is a respiratory sleep disorder characterized by a reduction (hypopnea) in or a complete cessation (apnea) of airflow in the upper airways at night, in the presence of breathing effort. The gold standard treatment for OSA is ventilation through continuous positive airway pressure (CPAP), although this often shows poor patient compliance. In recent years, transoral robotic surgery (TORS) has been proposed as a valid surgical treatment for patients suffering from OSA in a multilevel surgical setting. The aim of this study is to analyze the effects on QoL and daytime sleepiness of multilevel surgery for OSA (barbed pharyngoplasty + transoral robotic surgery). Furthermore, we compared the impact on QoL and daytime sleepiness of two different treatments for patients with moderate to severe OSA, such as CPAP and TORS. Sixty-seven OSA patients who underwent multilevel robotic surgery and sixty-seven OSA patients treated with CPAP were enrolled, defined as Group 1 and Group 2, respectively. The Glasgow Benefit Inventory (GBI) questionnaire was administrated to evaluate the changes in the QoL. Respiratory outcomes were evaluated and compared. Group 1 showed a GBI total average value of +30.4, whereas Group 2, a value of +33.2 (p = 0.4). General benefit score showed no difference between groups (p = 0.1). Better values of social status benefit (p = 0.0006) emerged in the CPAP Group, whereas greater physical status benefit (p = 0.04) was shown in the TORS Group. Delta-AHI (−23.7 ± 14.3 vs. −31.7 ± 15.6; p = 0.001) and Delta-ODI (−24.5 ± 9.5 vs. −29.4 ± 10.5; p = 0.001) showed better values in the CPAP group. Therapeutic success rate of the Multilevel TORS Group was 73.1% and 91% in the CPAP group (p = 0.01), respectively. Multilevel TORS and CPAP have a positive effect on the quality of life of OSA patients. Greater social support has been reported in the CPAP group and better physical health status in the TORS group. No statistical difference emerged in the reduction in daytime sleepiness between both groups. [ABSTRACT FROM AUTHOR]
