【 摘 要 】

Mucoceles of the paranasal sinus are epithelial lesions containing mucus, slow growth with expansive and osteolytic features that can involve surrounding structures such as orbit and intracranial cavity. The etiology of mucoceles is often associated with ostial obstruction of the impaired sinus. Presenting symptoms can include facial pain, headache, nasal obstruction, diplopia, decreased visual acuity, orbital globe displacement, facial swelling and meningitis, depending on the anatomic area involved. Mucoceles occur most frequently in the frontal and ethmoidal sinuses, without gender prevalence. The diagnosis is achieved through imaging exam. The gold standard in terms of diagnostic precision is computed tomography scan, although magnetic resonance imaging can be helpful in some cases. Currently, transnasal endoscopic management of mucoceles is preferred due minimal trauma and less morbidity. The present study describes two cases of frontoethmoidal mucoceles with orbital and intracranial involvement that were treated by transnasal endoscopic approach obtaining good outcomes, demonstrating safety and efficacy of this surgical approach.
