Paranasal sinus mucoceles with ophthalmologic manifestations: a 17-year review of 96 cases.

American Journal of Rhinology and Allergy 25(4):272 (2011) PMID 21819766

The purpose of this study was to assess the characteristics of paranasal sinus mucoceles with ophthalmologic manifestations with a focus on optic neuropathy. From January 1993 to May 2010, 96 consecutive patients diagnosed with paranasal sinus mucoceles with ophthalmologic manifestations were investigated. Clinical and therapeutic factors and demographics were reviewed from medical records. Statistical associations between clinical and therapeutic factors and visual outcomes after surgery were also analyzed. A total of 352 patients were diagnosed with paranasal sinus mucoceles and underwent surgical treatment. Ninety-six of them presented with ophthalmologic symptoms, and periorbital swelling and pain were the most common symptoms (36.4%) in those patients. Among the 96 patients with ophthalmologic manifestations, 18 (18.8%) were diagnosed with optic neuropathy based on the deterioration of their visual acuity and unilateral relative afferent papillary defect. Ten of these 18 patients showed improvements in their vision after surgical intervention. The statistical analysis of the association between clinical and therapeutic factors and visual outcomes showed that the presence of infection was the only significant factor (p = 0.023). Paranasal sinus mucoceles present various ophthalmologic manifestations. Among them, optic neuropathy may be one of the most devastating conditions. In treating optic neuropathy caused by mucoceles, the presence of infection was the only factor that had any influence on postoperative visual outcomes. Therefore, we conclude that not only surgical drainage and ventilation of the sinus are necessary, but infection control is also a vital factor in treating mucoceles with optic neuropathy.
