Background
Most common benign sinonasal tumour, most common in the frontoethmoid region and rarely the sphenoid.
Features
They are usually asymptomatic and picked up incidentally.
The prescence of multiple lesions may be associated with Gardner syndrome.
Management
Excision if symptomatic, otherwise observe with serial CT Sinus.
Asymptomatic
Frontoethmoid:
Monitor serial imaging, once a year for 3 years, then discharge with patient initiated follow up.
Sphenoid:
Higher risk for orbital/visual complications so probably warrant slightly longer period of observation
Symptomatic
Surgical excision
