Maxillary Sinus Mucosal Thickening with Orbital Floor Displacement on TMJ Evaluation

A 61-year-old female was referred for TMJ evaluation. During full-volume review, the radiologist identified severe mucosal thickening in the right maxillary sinus that was displacing the right orbital floor superiorly. The radiologist noted that while the radiographic appearance could be initially interpreted as severe sinusitis, the significant effect on the orbital floor means a pathologic process cannot be completely ruled out. Additionally, even in the case of sinusitis, the degree of orbital floor displacement raises concern that the orbital soft tissue could be affected in rare cases. The radiologist contacted the referring practice as soon as the report was completed and emphasized the need for referral to an ENT specialist to determine appropriate follow-up and rule out any underlying pathology.
