  • Title: Extensive sphenoethmoid mucocele--an endoscopic management.
    Author: Prasad KC, Alva B, Prasad SC, Shenoy V.
    Journal: J Craniofac Surg; 2008 May; 19(3):766-71. PubMed ID: 18520396.
    Abstract:
    Sphenoethmoidal mucoceles are rare tumors. They gradually expand in size and rarely produce bony destruction of sinus walls, leading to orbital, ocular, and intracranial involvement. We present a rare case of sphenoethmoidal mucocele with bone destruction and intracranial extension, who presented with nasal blockade and loss of visual acuity. Computed tomographic scan revealed a soft tissue mass, eroding the base of anterior cranial fossa, extending intracranially into the parasellar temporal fossa. The patient was treated successfully by endoscopic excision. Although a transfacial approach is generally preferred in cases of extensive mucoceles with intracranial extensions, a thorough anatomy of the nasal skull base and proficient use of the endoscope can be a good alternative to such lesions.
