OBJECTIVE: The aim of this study was to clarify the role of ostiomeatal complex obstruction in maxillary fungus ball. STUDY DESIGN AND SETTING: Comparative study in a hospital setting of the mean Lund-Mackay scores for the anterior ethmoid and frontal sinuses of 54 versus 48 patients with maxillary fungus ball versus chronic unilateral rhinosinusitis, respectively. RESULTS: In cases with partial opacification in the maxillary sinus, the anterior ethmoid and frontal sinuses were diseased in the chronic unilateral rhinosinusitis group but not in the maxillary fungus ball group. In cases with total opacification in the maxillary sinuses, all anterior ethmoid and frontal sinuses in both groups were diseased, but the disease condition of the frontal sinuses was significantly less severe in the maxillary fungus ball group (P < 0.001). CONCLUSION AND SIGNIFICANCE: In this era of evidence-based medicine, we provide statistical data supporting the principle that maxillary fungus ball is not associated with osteomeatal complex obstruction and that another as-yet-unexplained mechanism must be responsible. EBM RATING: B-3b.
