Abstract

BACKGROUND: Transoval biopsy of cavernous sinus (CS) lesions is the last non-invasive diagnostic option in those 15% of patients in whom etiology remains unclear in spite of extensive neuroradiological imaging, clinical assessment, and laboratory evaluation. However, there are no guidelines defining indications and the most appropriate technique for this procedure.

CASE DESCRIPTION: We present four patients in whom we performed X-ray and neuronavigation-assisted transoval CS biopsies using tip-cut needles.

CONCLUSION: The technique described allows the operator to determine the optimal angle for entering the CS, avoiding the complications due to distorted anatomy, and facilitating orientation once inside the CS. It reduces both radiation exposure as well as general anesthesia duration.

Keywords: Cavernous sinus lesions; foramen ovale biopsy; minimally invasive biopsy; tip-cut needle; transoval approach
