A Review of the Long-Term Efficacy of Submucosal Medpor Implantation for Empty Nose Syndrome: A Short Communication.

Abstract

To evaluate the long-term effects of submucosal Medpor implants in patients with empty nose syndrome (ENS), using the Sinonasal Outcome Test (SNOT) score as a measure of clinical improvement. A comprehensive search of six databases was conducted up to October 2024. The analysis included studies that examined the impact of submucosal Medpor implants on refractory ENS symptoms, as assessed by various symptom-specific questionnaires. Post-intervention SNOT scores were evaluated during follow-up periods of over 12 months, showing a statistically significant improvement in ENS symptoms (standardized mean difference [95% confidence interval]= 1.4676 [1.2067; 1.7285]; I²=37.2%). This meta-analysis indicates that submucosal Medpor implantation in patients with ENS is associated with significant long-term improvements in nasal symptoms.
