Background: Endoscopic resection (ER) for uncommon sinonasal malignancies (SNMs) has been reported to confer superior surgical outcomes compared to open resection (OR) based on indirect comparisons of limited evidence. Objective: The aim of this study was to pool all direct comparative studies in the literature to validate this potential superior association. Methods: Systematic searches of 7 electronic databases from their inception to April 2019 were conducted following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. There were 1001 articles identified for screening. Outcomes of interest were pooled as risk ratios (RRs) and mean difference (MD) and analyzed using a random-effects model. Results: There were 10 studies included in this meta-analysis, with 900 SNM patients in total where ER and OR were utilized in 399 (44%) and 501 (56%) cases, respectively. Compared to OR, random-effects (RE) modeling indicated ER resulted in statistically comparable complications (RR = 0.68; P-effect =.12) and recurrence (RR = 0.84; P-effect =.35). ER was associated with significantly shorter length of stay (LOS) compared to OR (MD = −2.9 days; P-effect <.01). Conclusions: The use of ER to manage SNM was associated with significantly favorable reduction in LOS compared to OR. However, with respect to other surgical outcomes and recurrence, the current literature does not indicate either ER or OR as statistically superior. Therefore, until greater validation of these associations can be proven, expectations that ER for SNMs confers superior surgical outcomes compared to OR should be tempered.
