CONCLUSION
In this cohort, the highest female-to-male ratio for MSFB at 51-60 years corresponded to the age of menopause. Patients with MSFB without IH were more likely to have DM, no female predominance, adjacent maxillary odontogenic pathology, and partial opacification of the sinus, compared to those with IH. These clinical features may aid earlier identification of MSFB without IH.
