ABSTRACT
OBJECTIVES:
To determine the anatomical variations of the lateral nasal wall and anterior skull base amongst populations in different geographical regions.DESIGN:
Systematic review and meta-analysis.METHODS:
Using PRISMA guidelines, SCOPUS and PUBMED databases were searched from inception until 1 March 2022. The regions and populations identified were from Europe, Asia, Middle East, Australia-New Zealand-Oceania, South America, North America and Africa. Random-effects model was used to estimate the pooled prevalence with 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistic and Cochran's Q test. MAIN OUTCOMEMEASURES:
Anatomical variations of the lateral nasal wall and anterior skull base confirmed by computed tomography scan.RESULTS:
Fifty-six articles were included with a total of 11 805 persons. The most common anatomical variation of the ostiomeatal complex was pneumatization of the agger nasi (84.1%), olfactory fossa was Keros type 2 (53.8%) and ethmoids was asymmetry of the roof (42.8%). Sphenoethmoidal and suprabullar cells have a higher prevalence in North Americans (53.7%, 95% CI 46.00-61.33) while asymmetry of ethmoid roof more common in Middle Easterns (85.5%, 95% CI .00-100). Bent uncinate process has greater prevalence in Asians while supraorbital ethmoid cells and Keros type 3 more common in non-Asians. The overall studies have substantial heterogeneity and publication bias.CONCLUSION:
Certain anatomic variants are more common in a specific population. The 'approach of analysis' plays a role in the prevalence estimates and consensus should be made in future studies regarding the most appropriate 'approach of analysis' either by persons or by sides.Palavras-chave
