Advanced neurosurgical care

Our expert neurosurgical team provides advanced surgical care for a wide range of neurological conditions. Although our neurosurgeons offer examinations in our Portsmouth office and in Rochester, most surgical procedures take place at Portsmouth Regional Hospital.

In addition to providing advanced surgical care, we believe in putting the needs of our patients first by creating individualized treatment plants. Our goal is to answer all questions concerning diagnosis, surgical treatment and recovery.

Brain condition treatment

Common conditions treated include:

  • Benign brain tumors/meningioma
  • Chiari type I malformation
  • Colloid cysts of the 3rd ventricle
  • Hydrocephalus
  • Malignant brain tumors
  • Metastatic brain tumors
  • Traumatic brain injury/head trauma

Our neurosurgical team uses advanced surgical methods to treats brain conditions, including:

Image guided cranial surgery

Image guided cranial surgery uses advanced technology that provides surgeons with detailed images of the surgical site on a computer screen. These enhanced images allow for increased accuracy and precision during brain surgery.

Deep Brain Stimulation (DBS)

DBS is a surgical procedure that helps patients function with movement disorders, such as essential tremors or Parkinson’s disease. During the procedure, a neurosurgeon will implant a small pacemaker-like device into the area of the brain that controls body movement.

DBS can reduce stiffness and tremors caused by movement disorders, to maximize your quality of life and range of motion.

Spine condition treatment

Our neurosurgeons using a variety of surgical methods to treat spine conditions, including:

  • Arthroplasty (disc replacement)
  • Tumor removal
  • Surgery for traumatic injuries

Common spine conditions treated include:

  • Disc disease
  • Herniated disc
  • Neck and back pain
  • Spine infection
  • Spinal Stenosis
  • Traumatic injuries

Multidisciplinary spine care

Our neurosurgery practice uses a virtual spine center to coordinate patient care and maximize treatment results. The virtual spine center allows our physicians to document patient progress as well as communicate with other specialists, including:

  • Interventional radiologists
  • Pain management anesthesiologists
  • Physiatrists
  • Physical therapists
  • Primary care physicians
  • Rehabilitation physiatrists
  • Surgeons

This collaboration provides patients access to a wide range of specialists in Rockingham

County. It also helps our doctors ensure that all patients receive care from the appropriate specialists and provides a continuity of care across providers.

General care plan

Our neurosurgeons understand that some conditions can be treated without surgery, which is why our general care plan can include:

  • Medical therapy, using muscle relaxants or anti-inflammatories
  • Pain therapy, including spinal blocks, trigger point injections, botox injections or steroid injections
  • Physical therapy to loosen painful or strained muscles
  • Surgical consideration (when other treatment modalities have failed)
