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

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. � Korean J Otorhinolaryngol-Head Neck Surg 2013;56:655-8 Key WordsZZAnterior clinoid process ㆍEndoscopic sinus surgery ㆍMucocele ㆍOptic neuropathy.
