    Abstract:
    INTRODUCTION: Paranasal sinus (PNS) mucoceles may involve orbit and have ophthalmic manifestations. The objective of this study was to investigate the clinical and radiological features affecting the ophthalmic manifestations in patients with PNS mucoceles involving the orbit. METHODS: Fifty-two patients underwent endoscopic sinus surgery for PNS mucoceles with orbital involvement were investigated. Ophthalmic manifestations included exophthalmos, ocular pain, diplopia, visual disturbance. The correlation between ocular symptoms and the mucocele volume, origin site of mucocele, and the involvement of extraocular muscles or optic nerve were evaluated. RESULTS: Ophthalmic manifestations were significantly higher in the anterior ethmoid and frontal sinus involvement. Exophthalmos was significantly increased in the involvement of anterior ethmoid sinus, frontal sinus, and superior group ocular muscles, but decreased in the mucocele of maxillary sinus. Ocular pain was significantly lower in the involvement of anterior ethmoid sinus, frontal sinus, and superior group ocular muscle. Diplopia showed no significant differences among clinical and radiological parameters. Visual disturbance was significantly higher in the involvement of posterior ethmoid sinus and sphenoid sinus. The volume of mucocele, relation to optic nerve, adjacent bony change, and duration of ocular symptom had no significant effect on ocular symptoms in patients with PNS mucoceles involving the orbit. CONCLUSION: The volume of mucocele did not affect the ophthalmic manifestations in patients with PNS mucoceles involving the orbit. Exophthalmos, ocular pain, and visual disturbance were significantly correlated with the involved sinus of PNS mucoceles.
