A Case of Recurred Visual Loss Caused by Anterior Clinoid Process Mucocele / 대한이비인후과학회지

ABSTRACT

The anterior clinoid process may be pneumatized by an extension of the sphenoid sinus air space. An anterior clinoid mucocele is a particularly rare entity, which can lead to optic complication due to its proximity to the optic nerve. Optic neuropathy is seldom recoverd if there is a delay in treatment for more than 10 days. The primary treatment for mucocele is surgical excision. We report a patient with mucocele of the anterior clinoid process that resulted in recurrent monocular visual loss. The patient underwent endoscopy-assisted transnasal marsupialization of mucocele with full recovery of visual function.
