SUMMARY: Dr. Frank Hsu and the UCIrvine Interdisciplinary Skull Base Surgery Group present their approach to Olfactory Groove meningiomas. (Drs. Hsu-neurosurgeon, Kuan-otolaryngologist, Malkasian-neurosurgeon-molecular biologist, Himsted -neurosurgeon-resident and others as consultants.) “Should the transnasal or intracranial approach be utilized?” Is discussed. How does the patient present to the clinician? Does the general neurological examination reveal the extent of the neurological deficits? What does more detailed otolaryngeal testing reveal? What fiber tracts are affected by tumors in this location? Taste, smell, and executive functions? Imaging. Is the dissection different from the intracranial vs transnasal approach. How should the surgeon manage the parts of the tumor he/she cannot see directly? What about post-op CSF leak? How is that managed transnasally? What are the complications with the intracranial approach? Their transnasal CSF leak rate is 1%. How is that achieved? Which approach does the patient like? What are the risks of each approach? Is either approach for removal similar in results? What is the outcome and Quality of Life? Excellent graphics, video and discussion. Good for Video and podcast but images are very helpful.
