Image-Guided Sinus Surgery in Sinonasal Pathologies With Skull Base/Orbital Erosion

OBJECTIVE: The aim of the study was to review the use and outcomes of image-guided sinus surgery (IGSS) in sinonasal pathologies with skull base/orbital erosion without intracranial or intraorbital extension. METHOD: A retrospective charts and medical records review was performed for 474 consecutive sinonasal surgeries performed by a single surgeon at tertiary, academic center from August 2010 to December 2013. RESULT: Fourteen subjects (mean age 27 years; 8 men and 6 women) were identified. Mucocele and tumor were the most common pathological indication for IGSS use in this case series. Orbital wall erosion was detected in 57%, skull base in 29%, and both sites in 14%. The average blood loss was 80 mL, the average operative time was 190 minutes, and the average hospital stay was 3 days. There was no major intra- or postoperative complications. Two patients required revision endoscopic sinus surgery. The mean follow-up was 14 months (range 8-36 months). CONCLUSION: Image-guided sinus surgery alone is safe and effective procedure for a variety of sinonasal pathologies with orbital and skull base erosion.
