Garni Barkhoudarian, MD
Co-Director Pituitary Disorders Center; Neurosurgery Director, Adult Hydrocephalus Center & Facial Pain Center.
Director, Skull-Base and Endoscopic Microdissection Anatomy Laboratory Vice-Chair Education, CNS Garni Barkhoudarian, MD, is a board-certified, fellowship-trained neurosurgeon with a focus on skull base and minimally invasive endoscopic surgery.
Dr. Barkhoudarian has particular interest and expertise in pituitary and paracellar tumors, brain tumors, skull-base tumors (including meningiomas, craniopharyngiomas, chordomas and schwannomas), intra-ventricular brain tumors, colloid cysts, trigeminal neuralgia, hemifacial spasm and other vascular compression syndromes. For virtually all tumors and intracranial procedures, Dr. Barkhoudarian applies the keyhole concept of minimizing collateral damage to the brain and its supporting structures using advanced neuroimaging and neuro-navigation techniques along with endoscopy to improve targeting and lesion visualization.
Along with Drs. Marisa Chang and Daniel Franc, Dr. Barkhoudarian leads the Pacific Facial Pain Center, which offers a 360-degree approach to trigeminal neuralgia, hemifacial spasm, glossopharyngeal spasm and other facial pain syndromes. This includes medication therapy, percutaneous procedures, stereotactic radiosurgery and endoscopic microvascular decompression of the trigeminal or facial nerves.
As Director of the Pacific Adult Hydrocephalus Center, he works with Dr. Daniel Franc to treat patients with various condition involving cerebrospinal fluid anomalies. This includes hydrocephalus (obstructive, acquired and normal pressure), colloid cysts, cerebrospinal fluid leaks, intracranial hypotension and idiopathic intracranial hypertension.
Dr. Barkhoudarian’s research interests include evaluating outcomes of pituitary and brain tumor surgery. He is also involved in the biomarkers research program for pituitary adenomas, meningiomas and metastatic brain tumors, as well as evaluating potential mechanisms and markers of invasive and atypical tumor progression. He is an investigator in a number of clinical trials evaluating the efficacy of various medical or chemotherapies for pituitary tumors and malignant brain tumors.
As director of the Skull-Base and Endoscopic Microdissection Anatomy Laboratory, he conducts neuroanatomical analysis, advancing the procedures and technology used for minimally invasive surgery. Research fellows from around the world perform observational fellowships for periods of 3- 6 months at a time, allowing them to learn these techniques and apply them in their home countries. In collaboration with Dr. Daniel Kelly, PNI Director, Dr. Barkhoudarian also oversees the Clinical Neurosurgical Fellowship.
