Fronto-orbital-ethmoid mucoceles

Mucoceles are mucus filled cavities that most often occur in the frontal sinuses. In advanced stages, they can expand to large dimensions causing bone remodeling and erosion, and can extend into the intracranial cavity and orbits. In addition to symptoms associated with chronic rhinosinusitis, in advanced stages, symptoms may include headache and ophthalmologic problems such as proptosis and diplopia. Successful management requires involved sinus drainage, preferably endoscopically, or sinus cavity obliteration.
