The authors present a patient casewith giant frontal sinus mucocele with intracranialspread after numerous operations for nasal polyposis. Patient suffered no symptoms since lastoperation 7 years ago. A 2-month progressive bony prominence above upper eyelid and decreasednasal patency appeared to be nasal polyposis and frontal sinus mucocele eroding posterior andinferior sinus wall according to anemnesis and further clinical investigation. The intracranialgrowth manifested no neurological deficit. The expansive process caused laterocaudal eyeballdislocation. The mucocele was resected and giant nasal polyps were extracted from Raven’ssubfrontal approach in cooperation with neurosurgeon. The postoperative course was uneventful.The cosmetic result 3-month after surgery was more than satisfactory. A follow-up MRI and endoscopyof nasal cavity revealed no sign of recurrence. In conclusion authors stress advantages ofRaven’s approach. Furthermore, indication criteria for different surgical approaches in frontalsinus mucocele treatment are discussed.
