Background

The highest level of care comes from a multidisciplinary approach to any medical problem, and this is embraced wholeheartedly here at Children's Hospital of Philadelphia (CHOP). In neurosurgery we collaborate closely with experts from every field of pediatric medicine and surgery. I have a broad interest in all aspects of pediatric neurosurgery, including epilepsy and functional neurosurgery, brain and spine tumors, congenital and traumatic spine surgery, and craniovertebral junction abnormalities. 

It is a great privilege to serve as Director of Epilepsy and Functional Neurosurgery at CHOP. In our Pediatric Regional Epilepsy Program, I have the pleasure of working with our epileptologists, neuroradiologists, neuropsychologists, social workers and pathologists to develop a highly personalized approach to each epilepsy patient. When a child’s epilepsy is not able to be controlled with medication, we formulate the most minimally invasive surgical plan to address the problem. We can avoid large operations for many children who require epilepsy surgery with a variety of techniques. These include robotic-assisted stereoEEG, which is percutaneous depth electrodes, for precise monitoring of the epileptic network and identification of the source of seizures. We use laser ablation for corpus callosotomy, hypothalamic hamartoma, mesial temporal sclerosis, or small, deep seizure sources. We employ purely disconnective techniques for hemispherotomy through a small craniotomy, and provide vagal nerve stimulators that do not require brain surgery at all. What inspires me is providing children and their families with the best possible seizure control while minimizing discomfort, and getting them back to their lives as quickly as possible. Our research is focused on understanding the complex interplay among epilepsy genetics, EEG, and clinical information to provide both better medical and surgical therapies. 

In our multidisciplinary cerebral palsy and spasticity clinics, I work with our rehabilitation doctors, physical and occupational therapists, neurologists, orthopaedists, social workers, neurophysiologists, nursing and other staff to develop a multi-faceted treatment plan for patients with spasticity, which sometimes involves neurosurgery, including selective dorsal rhizotomy or baclofen pump placement. In our deep brain stimulation program, I collaborate with our movement disorder neurologists to identify children with dystonia who will benefit from deep brain stimulation. When we are able to improve our patients’ control and function or help a child walk with these procedures, it is deeply gratifying.
