Also, we evaluated the effect of combinations of those factors on the incidence of MSFB. METHODS: Three hundred patients were divided into MSFB, normal, and chronic rhinosinusitis (CRS) groups. We reviewed paranasal computed tomography scans for the presence of deviated nasal septum, concha bullosa (CB), Haller cells, and various dental factors. Also, we measured the ethmoid infundibulum, maxillary natural ostium, and CB. RESULTS: Maxillary sinus fungal ball showed a more significant association with CB compared to the other 2 groups (37%, P < .05). The MSFB group had a lower rate of Haller cells than the normal group (10% vs 22%, respectively; P < .05). Also, the MSFB group had a wider maxillary sinus ostium than the normal group (7.07 ± 1.8 vs 5.48 ± 1.3 mm; P < .01). Moreover, the combination of CB and Haller cells was significantly associated with a decreased rate of the fungal ball (P = .047, odds ratio = 0.694). The dental factors were more prevalent in the MSFB and CRS groups (73% and 75%, respectively) than in the normal group (32%, P < .001). CONCLUSIONS: Maxillary sinus fungal ball is significantly associated with CB, Haller cells, an increased maxillary sinus ostium size, and dental factors.
