Abstract
Background: To assess the diagnostic utility of middle meatal culture (MMC) in patients with acute and chronic sinusitis; Methods: Six databases were thoroughly reviewed up to March 2022. Sensitivity, specificity, and negative and positive predictive values were extracted. Methodological quality was evaluated using the QUADAS-2 instrument; Results: Fifteen reports were analyzed. MMC results exhibited a significant correlation (r = 0.7590, 95% confidence interval [CI] [0.6855; 0.8172], p < 0.0001) with those of maxillary sinus puncture. The diagnostic odds ratio (DOR) of MMC (reference = maxillary sinus culture) was 8.5475 [3.9238; 18.6199]. The area under the summary receiver operating characteristic curve was 0.761. The sensitivity and specificity of MMC were 0.7759 [0.6744; 0.8526] and 0.7514 [0.6110; 0.8534], respectively. We performed subgroup analysis based on age (children vs. adults), duration of disease (acute vs. chronic), and specimen collection method (biopsy, swabs, suction tips). The DORs, specificities, and negative and positive predictive values varied significantly. Diagnostic accuracy was highest for children and individuals with chronic disease, and when samples were collected via suction.; Conclusions: MMC provided fair diagnostic accuracy in patients with acute or chronic sinusitis. Although some institutional differences were evident, the middle meatal and maxillary sinus culture results were similar.
