Endoscopic endonasal drainage of sphenoid sinus mucocele in a child

Abstract

The sphenoid sinus is the least common site for mucocele of all paranasal sinuses. It is very rare in children, especially in those younger than 12 years when pneumatization of the sphenoid sinus is completed. We report a case of histologically proven sphenoid mucocele in a 8 year old child. The child presented with an acute onset of significant headache and vomiting. Also he had chronic problem of visual impairment. His vision gradually improved after endoscope endonasal sphenoidotomy and drainage of the sinus content which resolved all his symptoms. The rareness of paranasal sinus mucocele in children especially sphenoid occurrence prompted the authors to discuss the aetiology radiological imaging findings and the role of endoscopic endonasal sphenoidotomy and review of literature.
