INTRODUCTION: Obstructive sleep apnea (OSA) and snoring are common conditions that disrupt sleep, leading to significant physical and emotional challenges that affect daily life and overall well-being. While non-surgical treatments like continuous positive airway pressure (CPAP) are effective, many patients find them challenging to maintain. Cautery-assisted palatal stiffening (CAPS), with or without uvulectomy, offers a minimally invasive surgical alternative to improve symptoms and enhance quality of life (QoL). AIM: This study aims to assess and compare the effects of CAPS, with and without uvulectomy, on post-surgical QoL in patients with OSA or snoring. MATERIALS AND METHODS: This retrospective cohort study included 94 patients who underwent CAPS, with or without uvulectomy, at King Hamad University Hospital in Bahrain to treat OSA or snoring. QoL was assessed using the Short-Form Health Survey (SF-36), evaluating physical and emotional well-being. RESULTS: Among the 94 patients, CAPS improved physical functioning (mean score: 83.03) and general health (72.98). A trend toward greater emotional well-being was observed in the CAPS-only group compared to the uvulectomy group (p = 0.057). Over half of the participants (53.2%) reported feeling significantly better overall. CAPS effectively enhanced physical QoL, with some limitations remaining in emotional health. CONCLUSIONS: CAPS and CAPS with uvulectomy significantly improve post-surgical QoL, especially in physical functioning, though some emotional challenges may persist. These findings support CAPS as a beneficial option for patients, particularly for enhancing physical well-being.
