Summary
Mucosal reconstruction with flaps or grafts improves frontal sinus neo-ostium patency after Draf III surgery. Further research with standardized methods is needed to confirm benefits for clinical outcomes.
Area of Science:
- Otolaryngology
- Neurosurgery
- Surgical Innovation
Background:
- Frontal sinus drill-out procedures (Draf IIb/III) aim to restore sinus ventilation.
- Neo-ostium patency is crucial for long-term surgical success.
- The role of mucosal reconstruction in maintaining patency requires further investigation.
Purpose of the Study:
- To evaluate the impact of mucosal grafts and flaps on neo-ostium patency and clinical outcomes.
- To assess the effectiveness of mucosal reconstruction in Draf IIb/III procedures.
Main Methods:
- Systematic review and meta-analysis of PubMed, Medline, Cochrane Library, Scopus, and Web of Science.
- Included studies followed Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.
- Extracted data on patient demographics, surgical outcomes, and neo-ostium patency rates.
Main Results:
- Nine studies with 375 patients were included; four were eligible for meta-analysis.
- Mucosal flaps/grafts significantly improved neo-ostium patency (RR 1.087) and reduced area loss (MD 19.52%) in Draf III procedures.
- High heterogeneity in clinical outcomes limited synthesis.
Conclusions:
- Mucosal reconstruction may enhance neo-ostium patency, particularly in Draf III procedures.
- Variability in study design and outcome reporting presents limitations.
- Standardized methodologies are essential for accurate assessment of mucosal grafting's role.
