Procedures & Conditions

Specialized care for the brain, skull base & spine

Explore the conditions Dr. Asmaro treats and the advanced surgical techniques he uses to treat them.

Spine

Spine Conditions

A comprehensive approach to degenerative, structural and nerve-related conditions affecting the cervical and lumbar spine.

SEE CONDITIONS

Cervical and Lumbar Spondylosis

Treatment of age-related wear on the spinal discs and joints in the neck and lower back.

Lumbar Stenosis

Surgical decompression to relieve narrowing of the spinal canal in the lower back that compresses nerves, causing pain, numbness, or weakness in the legs.

Spondylolisthesis

Surgical stabilization when one vertebra slips forward over another, causing pain or nerve compression.

Degenerative Disc Disease

Diagnosis and treatment (surgical and non-surgical) of disc wear that causes chronic back or neck pain.

Disc Herniation

Surgical removal or repair of herniated disc material pressing on spinal nerves.

Radiculopathy

Treatment of nerve root compression causing pain, numbness, or weakness radiating into the arms or legs.

Spine Deformity and Scoliosis

Surgical correction of abnormal spinal curvature to relieve pain and improve function.

Spine Tumors

Evaluation and treatment of benign and malignant tumors of the spine and spinal cord, including intramedullary tumors (ependymomas, astrocytomas), meningiomas, schwannomas, and metastatic disease. Symptoms can include persistent back pain, numbness, weakness, or bowel and bladder changes.

Spine Surgery

Developed surgical techniques ranging from minimally invasive procedures to complex spinal reconstruction.

SEE PROCEDURES

Lumbar Disc Replacement and Arthroplasty

Motion-preserving alternative to fusion, replacing a damaged lumbar disc with an artificial one.

Cervical Disc Replacement and Arthroplasty

Motion-preserving artificial disc replacement in the neck to relieve pain while maintaining flexibility.

Minimally Invasive Spine Surgery

Small-incision techniques to treat spine conditions with less muscle disruption, less pain, and faster recovery.

Fusion Surgery

Permanently joining two or more vertebrae to stabilize the spine and relieve pain from instability.

Spine Tumor Surgery

Minimally invasive and open microsurgical removal of tumors inside the spinal cord (intramedullary), around the cord, and in the spinal column, with decompression and stabilization when needed. The goals are to remove as much tumor as safely possible, preserve neurologic function, and maintain spinal stability.

Spinal Decompression (Laminectomy)

Minimally invasive removal of bone and thickened ligament that narrow the spinal canal in the neck or lower back. Taking pressure off the spinal cord and nerves relieves pain, numbness, tingling, and weakness in the arms or legs.

Discectomy

Minimally invasive removal of herniated disc material pressing on a nerve or the spinal cord in the neck or lower back. It's done through a small incision to relieve radiating arm or leg pain, numbness, and weakness.

Spine Surgery

Full-spectrum surgical care for spinal conditions, from minimally invasive procedures to complex reconstructive surgery.

Brain & Skull Base

Brain Tumors

Conditions affecting the brain and surrounding structures, treated with advanced imaging and minimally invasive surgical techniques.

SEE PROCEDURES

Brain Tumor

Diagnosis and surgical treatment of benign and malignant brain tumors using advanced imaging and minimally invasive techniques.

Meningioma

Surgical removal of tumors arising from the membranes covering the brain and spinal cord, often using minimally invasive approaches.

Schwannoma

Microsurgical or endoscopic removal of nerve sheath tumors (e.g., acoustic neuroma), with a focus on preserving nerve function.

Chordoma (Skull Base)

Fellowship-trained endoscopic skull base surgery to remove these rare, locally aggressive tumors arising near the base of the skull, with an emphasis on complete resection to reduce recurrence risk.

Neuro-Oncology

Comprehensive neuro-oncologic care, from diagnosis through surgical resection, for tumors of the brain, spine, and skull base.

Skull Base & Pituitary

Fellowship-trained expertise in minimally invasive endoscopic surgery for complex skull base and pituitary conditions.

SEE PROCEDURES

Pituitary Tumor | Pituitary Adenoma

Fellowship-trained endoscopic (transnasal) removal of pituitary tumors, aimed at complete, curative resection rather than partial debulking — restoring normal hormone function and avoiding regrowth.

Acromegaly

Advanced endoscopic surgical technique achieves remission rates of over 90%, compared to the historical average of ~50% with conventional approaches — offering patients a real chance at biochemical cure rather than lifelong medication or repeat surgery.

Cushing Disease

Precise, fellowship-trained endoscopic removal of ACTH-secreting pituitary tumors, targeting complete cure of excess cortisol production rather than symptom management alone.

Prolactinoma

Surgical cure for prolactin-secreting tumors in patients who don't respond to or can't tolerate medication — an alternative to lifelong drug therapy.

Craniopharyngioma

Complete surgical resection using advanced endoscopic skull base techniques, aiming to eliminate the tumor and reduce the risk of recurrence — critical given how aggressively these tumors can regrow if incompletely removed.

Rathke's Cleft Cyst

Endoscopic removal of fluid-filled cysts near the pituitary gland causing symptoms like headache or vision changes.

Skull Base Tumors (General)

Fellowship-trained expertise in complex skull base pathology, with a surgical philosophy centered on complete, curative tumor removal — avoiding the "leave some behind and radiate" approach common elsewhere.

Skull Base Surgery

Advanced, minimally invasive endoscopic access to hard-to-reach tumors at the base of the skull. Dr. Asmaro is the only surgeon in Michigan performing cavernous sinus endoscopic skull base surgery — a highly specialized technique for tumors invading this complex, vessel- and nerve-dense region.

Pituitary Surgery

Endoscopic, minimally invasive access to the pituitary gland for tumor removal with faster recovery than traditional open surgery.

Cranial Nerve &
Vascular

Fellowship-trained expertise in minimally invasive endoscopic surgery for complex skull base and pituitary conditions.

SEE PROCEDURES

Trigeminal Neuralgia

Diagnosis and surgical treatment (including microvascular decompression) of this severe facial pain condition.

Hemifacial Spasm

Microvascular decompression surgery to relieve involuntary facial muscle spasms caused by nerve compression.

Microvascular Decompression (MVD)

A precise microsurgical procedure to relieve pressure on cranial nerves from adjacent blood vessels, treating conditions like trigeminal neuralgia and hemifacial spasm.

Cerebral Aneurysm

Surgical treatment of weakened, bulging blood vessels in the brain to prevent or treat rupture and hemorrhage.

Arteriovenous Malformation (AVM)

Surgical, collaborative endovascular, and/or radiosurgical treatment of abnormal tangles of blood vessels in the brain that carry a risk of bleeding or seizures.

Chiari Malformation

Surgical decompression to relieve crowding at the base of the skull where the brain meets the spinal canal.

Hydrocephalus

Surgical treatment (shunt placement or endoscopic third ventriculostomy) to manage excess fluid buildup around the brain.

Minimally Invasive
Brain Surgery

Advanced techniques designed to access and treat brain and skull base conditions while minimizing disruption to surrounding tissue.

SEE PROCEDURES

Endoscopic Brain Surgery

Using small incisions and specialized cameras to access and treat brain and skull base conditions with less tissue disruption.
