Temporary loss of visual acuity in ethmoidal mucocele after endonasal surgery. A case report

摘要

A posterior and/or ethmoidal mucocele remains a rare occurrence. The condition usually follows a past history of sinonasal surgery. Extension of the lesion may have ophtalmo- logical implications, with the possibility of causing visual impairment. The predilection for a site of origin in the posterior sinuses explains the frequent absence of nasal symptoms, and the usual pattern of discovery by the ophtalmologist. Modern imaging techniques, especially scanning, allows the diagnosis to be made immediately after the first orbital symptoms.
