Deep brain stimulation (DBS) surgery typically takes four to six hours for the main procedure, where electrodes are placed in the brain. A second, shorter procedure to implant the battery pack in the chest takes about 45 minutes to an hour and is scheduled days to a week later. So while the total time in the operating room adds up to roughly five to seven hours across both stages, the process is spread over two separate surgical days.
Stage 1: Electrode Placement
The first and longest part of DBS surgery is placing thin electrodes into precise areas of the brain that control movement. The surgery itself runs about three to four hours, but the entire process on that day, including preparation, frame placement, and brain imaging, lasts four to six hours.
Before the surgeon begins, a stereotactic frame (a rigid head frame that guides instruments with millimeter accuracy) is attached to your skull. Advanced brain scans are taken before and during surgery to map exactly where the electrodes need to go. This imaging and setup accounts for much of the extra time beyond the surgery itself.
Many centers perform this stage with the patient awake under local anesthesia. Staying awake allows the surgical team to test the electrodes in real time, asking you to move your hands or speak so they can confirm the placement is correct. An “asleep” approach using general anesthesia and real-time MRI guidance is also available at some centers, and it can shorten the procedure by eliminating some of the intraoperative testing steps.
If you need electrodes on both sides of the brain (bilateral DBS), some surgeons place both leads in a single session, which extends the operating time. Others prefer a staged approach, doing one side at a time in separate operations. The staged method means a longer overall timeline but reduces the continuous time you spend in surgery, which some centers believe lowers the risk of complications.
Stage 2: Battery Pack Implantation
About one to two weeks after electrode placement, you return for a second outpatient procedure. The surgeon implants a small pulse generator, similar to a pacemaker, under the skin near your collarbone or in the upper chest area. Thin extension wires are tunneled under the skin to connect the generator to the electrodes in your brain.
This stage is performed under general anesthesia and takes roughly 45 minutes to an hour. It is a much simpler procedure than the first stage, and most people find the recovery straightforward.
Hospital Stay for Each Stage
For the electrode placement, you typically come in the morning of surgery and go home the next day. One overnight stay is standard, though your medical team may keep you longer depending on your overall health and how you recover. The battery pack implantation is usually an outpatient procedure, meaning you go home the same day.
What Recovery Looks Like
Physical recovery from both procedures is relatively quick. Swelling around the eyes after electrode placement is common and usually resolves within one to two weeks. Tenderness or numbness near the incision sites and behind the ear can linger for up to a month. Some bruising near the surgical areas is normal and fades gradually. Most people return to light daily activities within a few weeks.
The device is not turned on immediately. About four to five weeks after the electrodes are placed, you have your first programming session with a neurologist who specializes in DBS. During this visit, the stimulator is switched on and the team tests multiple settings to find the combination that gives you the most symptom relief. This initial session is longer than follow-up visits because it involves systematic testing of different configurations.
Finding the optimal settings is not a one-visit process. Fine-tuning typically takes weeks to months, with periodic appointments to adjust the stimulation. Each person responds differently, so the programming timeline is highly individual. Some people notice dramatic improvement at the first session, while others see gradual gains as settings are refined over several visits.
Full Timeline From Start to Finish
Here is a realistic picture of the overall timeline:
- Day 1: Electrode placement surgery (4 to 6 hours total, including prep), followed by an overnight hospital stay.
- 1 to 2 weeks later: Battery pack implantation (about 45 minutes to 1 hour), typically same-day discharge.
- 4 to 5 weeks after electrode placement: Initial programming session where the device is turned on.
- Following weeks to months: Ongoing programming adjustments to optimize symptom control.
So while the actual time spent in surgery totals roughly five to seven hours, the full process from your first operation to a fully optimized, working system spans about two to three months. Planning for this extended timeline helps set realistic expectations about when you will feel the full benefits of the procedure.
