Sinus mucoceles are benign, slowly enlarging, mucous-secreting, cystic lesions whose expansile growth may lead to compressive neuropathies. We present the case of a 70-year-old woman with a long-standing history of headaches and progressive ocular neuropathy who underwent an endoscopic resection of a large sphenoid sinus mucocele resulting in immediate improvement of her neurological symptoms. ...

ABSTRACT The Sphenoid Sinus is considered the paranasal sinus with more variation to degree of pneumatization. Thus, this work aimed report first case on interference anatomical for orthognathic surgery. A 18- year-old woman, isolated cleft palate repaired, was submitted surgery correct maxillomandibular skeletal discrepancy. cone beam computed tomography (CBCT) exam performed preoperative plan...

The computed tomographic and angiographic features of 15 histologically proven primary extradural juxtasellar tumors were retrospectively reviewed. Five chordomas were characterized by prominent bone erosion and a significant posterior fossa component. Four trigeminal nerve neuromas each demonstrated bone erosion centered about Meckel's cave and moderate to marked contrast enhancement. Two cave...

A paranasal sinus mucocele is an epithelial-lined, mucus-containing sac that completely fills the and forms expandable cystic structure. It most commonly affects frontal ethmoidal sinuses, rarely maxillary sphenoid sinuses. Orbital displacement or external disfigurement resulting from expansion of ethmoid sinuses common; however, facial asymmetry caused by bone remodeling rare. We describe a ca...

Mucocele is defined as an epithelial-lined, mucus-containing benign sac completely filling the sinus and can be seen expanding to induce pressure effects on surrounding structures. Frontoethmoidal mucocele is by far the most common due to the complexity of its drainage, and incidence of maxillary mucocele is least. A 20-year-old female presented with a chief complaint of protruding right eyebal...

A 10-year-old girl with no nasal or respiratory symptoms developed a headache lasting a few hours. The next day she became totally blind in the right eye and over 5 days vision in the left eye deteriorated to bare light perception. The diagnosis of a sphenoid sinus mucocele was made radiologically and drainage via an endonasal sphenoidectomy produced 12 ml of brownish fluid. Endoscopic biopsy o...
