Minimally Invasive, Hair-Sparing Brain Tumor Surgery
Minimally invasive cranial surgery means planning the smallest opening that safely reaches the tumor, guided by high-resolution navigation. For many tumors that is a keyhole craniotomy of a few centimeters, often through an eyebrow or behind the hairline. For deep tumors, a tubular retractor the width of a finger passes between brain fibers rather than through them. Hair-sparing technique means only a narrow strip is trimmed, so most patients have no visible sign of surgery once the incision heals.
Dr. Daggubati combines these approaches with intraoperative MRI, fluorescence-guided resection (5-ALA) for gliomas, and awake mapping when a tumor lies near speech or motor areas.
Who it is for
- Meningiomas
- Gliomas and glioblastoma
- Brain metastases
- Colloid cysts and intraventricular tumors
- Cavernous malformations and other lesions requiring removal
Why we use it
- Smaller incision, less scalp and muscle pain
- Hair preserved
- Shorter hospital stay (often 1–3 days)
- Reduced brain retraction
- Faster return to normal life and to oncology treatment
How the procedure is done
- A navigation MRI maps the tumor and surrounding pathways.
- The smallest safe approach is planned; hair along the incision is trimmed, not shaved.
- A keyhole opening is made and the tumor removed under the microscope or endoscope with navigation and, where used, fluorescence.
- Intraoperative MRI or ultrasound confirms the extent of removal before closure.
- The bone is replaced with tiny plates and the incision closed with absorbable sutures.
Recovery
Most patients are walking the day after surgery and home in 1–3 days. Fatigue is normal for several weeks. Driving resumes when cleared (and only after any seizure precautions are complete). Return to work is usually 2–6 weeks depending on the job.
Risks, stated plainly
Bleeding, infection, seizure, stroke, new neurological deficit, spinal fluid leak, incomplete removal. Risk varies by tumor location and is discussed in detail before surgery. Dr. Daggubati reviews the specific risks for your situation in person before any decision is made.
Preparing for this surgery
Dr. Daggubati has written detailed guides for this procedure covering medications to stop, prehabilitation, the day of surgery, and a week-by-week recovery timeline.
Common questions
How long is a craniotomy?
Typically 2–5 hours depending on the tumor. You will be in the recovery area and then a monitored bed overnight.
Will I have a visible scar?
Incisions are placed within the hair or in natural creases whenever possible, and hair is preserved on both sides. Most scars are not visible once healed.
