This is my teenage patient with an excellent result after acoustic neuroma surgery. Dr. Bigelow and I were able to save her hearing and of course her facial function. She has totally normal hearing and complete resection. Hear her story.

Back to another profile in patient courage! This time we have a dental student who is having difficulty walking and taking her tests. An astute orthopedic surgeon finally realizes this is not an orthopedic problem but rather a neurologic problem. She has an epidermoid cyst compressing her brainstem.

Profiles in Patient Courage is my attempt to provide patients a way to tell their own story about their condition. When I do brain surgery, I want patients ...

I have never been on the track before, but I found analogies between Acoustic Neuroma Association surgery and track driving. Learn the line (anatomy), study with mentors, concentrate.

Next time I go, I am bringing the gopro and the DJI! Will get more video.

I am not a federal worker, and I cannot understand the stress that the new administration is creating in our federal employees.

However, I have an answer for Elon Musk. Over the past one week, I saw 49 patients in the clinic. I operated on seven brain tumor patients (five of whom had skull base tumors -- acoustic neuroma, sphenoid wing meningioma, tuberculum sella meningioma and two pituitary adenomas). I did two MVDs (one for Hemifacial spasm and one for trigeminal neuralgia). I placed a vp shunt, and I treated four patients with Gamma Knife stereotactic radiosurgery. I also met with my students to review research projects.

My Boss are My Patients!

I believe that meaning and justification can be found in the care of patients.

I am not a federal worker, and I cannot understand the stress that the new administration is creating in our federal employees. However, I have an answer fo...

I was asked to speak about my research on tumor dyes at the 12th Annual Penn Neuro-Oncology symposium last week. I wasn't going to post this, but my patient called in to let me know she appreciated the talk.
