What this trial studies

This observational study aims to assess the impact of maxillomandibular advancement (MMA) surgery on the quality of life in patients suffering from obstructive sleep apnea (OSA). Participants will complete online surveys to evaluate their quality of life using various questionnaires, including the SF-36, OHIP-14, and EQ-5D-3L. The study will involve 80 patients who qualify for MMA surgery and a control group of patients without OSA, with data collected on their health metrics such as height, weight, and blood pressure. The goal is to determine whether MMA surgery leads to significant improvements in quality of life for OSA patients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who have been diagnosed with obstructive sleep apnea and qualify for MMA surgery.

Not a fit: Patients who do not qualify for MMA surgery or have other severe medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence that MMA surgery significantly enhances the quality of life for patients with obstructive sleep apnea.

How similar studies have performed: While there have been studies on MMA surgery for OSA, this specific observational approach focusing on quality of life outcomes is relatively novel.
