Abstract
The differential diagnosis for trigeminal neuralgia like-symptoms includes cerebellopontine angle lesions causing regional mass effect upon the trigeminal nerve ( Fig. 1 ). Here we present an operative video manuscript of a patient experiencing trigeminal neuralgia, secondary to an epidermoid cyst, in which a retrosigmoid craniectomy was performed to resect the epidermoid and decompress the trigeminal nerve ( Fig. 2 ). This video highlights the operative nuances to achieving a successful surgery, including appropriate patient positioning, dural exposure to the transverse-sigmoid sinus junction, arachnoid dissection, and decompression of cranial nerves. A gross total resection was achieved; the patient reported immediate relief of facial pain postoperatively and has been pain free at the ten month follow-up.
