What this trial studies

This clinical trial aims to evaluate the effectiveness of endoscopic sinus surgery in improving the quality of life for patients suffering from recurrent acute rhinosinusitis. Participants will be randomly assigned to either an intervention group receiving the surgery along with medical treatment or a control group receiving only medical treatment. The primary outcome will be measured using the SNOT-22 quality of life questionnaire, with follow-ups occurring 5 to 6 months after the intervention. Additional data will be collected on sinusitis episodes, medical appointments, medication use, and any adverse events related to the surgery.

Who should consider this trial

Good fit: Ideal candidates are adults who have experienced multiple episodes of acute sinusitis and have not responded to conservative medical treatments.

Not a fit: Patients with chronic rhinosinusitis or those with conditions that prevent same-day surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly enhance the quality of life for patients with recurrent acute rhinosinusitis.

How similar studies have performed: Previous studies have shown that surgical interventions for sinusitis can lead to improved patient outcomes, suggesting a potential for success in this approach.
