At a glance
Nerve repair by microsurgery is a surgical procedure in which a surgeon uses a high-powered microscope and very fine instruments to reconnect or reconstruct a damaged nerve so that feeling and movement can return to the affected area.
A nerve is like an electrical cable made of thousands of tiny fibres. When the cable is cut or badly crushed, signals between the brain and the body cannot get through. The surgeon trims the damaged ends, aligns the fibres as precisely as possible, and stitches the nerve sheath (the outer sleeve of the nerve) together with sutures finer than a human hair. If the gap between the two ends is too wide to bridge directly, a short piece of nerve taken from elsewhere in the body, called a nerve graft, is used to fill the space. Over the following months, the nerve fibres slowly grow back through the repaired channel.
Medical Condition
Nerve repair microsurgery is used when a nerve has been severed, torn, or severely damaged and the body cannot heal it on its own. The most common setting is traumatic injury to the hand, wrist, forearm, or arm, but the technique is also used in other parts of the body.
- Sharp cuts (lacerations) that completely sever a nerve, for example from broken glass or a knife
- Crush injuries where the nerve is badly compressed and the protective sheath is destroyed
- Stretch injuries (avulsions) where the nerve is pulled apart, often seen in high-speed road accidents
- Nerve damage caused by a tumour pressing on or growing into the nerve
- Neuroma (a painful ball of tangled nerve fibres) that forms after a previous injury or amputation
- Nerve damage that did not heal properly after an earlier repair or that developed scar tissue blocking recovery
- Certain birth-related nerve injuries, such as brachial plexus palsy (weakness or paralysis of the arm caused by nerve injury during delivery)
Microsurgery is not suitable for every nerve problem. Your doctor will discuss other options if any of the following apply.
- The injury is very old and too much time has passed for the target muscles to benefit from re-innervation (reconnection of nerves to muscles)
- The skin and tissue around the damaged nerve are too infected or too scarred to support healing
- The patient has severe uncontrolled medical conditions that make a long general anaesthetic unsafe
- The nerve damage is mild and expected to recover fully with non-surgical treatment such as physiotherapy or splinting
Risks & Complications
Nerve repair microsurgery carries real risks, and outcomes depend heavily on the type of injury, the nerve involved, and how quickly surgery is performed after the injury.
- Incomplete recovery of feeling or movement, which is common because nerves regrow slowly and muscle fibres can deteriorate while waiting
- Chronic pain or abnormal sensations (such as tingling, burning, or hypersensitivity) in the area supplied by the repaired nerve
- Neuroma formation at the repair site, causing a tender lump that may need further treatment
- Loss of feeling or weakness at the donor site if a nerve graft was taken from another part of the body
- Infection at the incision or graft harvest site
- Wound breakdown or poor healing, especially in patients with diabetes or poor circulation
- Scar tissue forming around the repair and slowing nerve regrowth
- Anaesthesia-related complications, which your anaesthetist will discuss before surgery
- Need for a second operation if the initial repair does not achieve adequate nerve recovery
Preparation & Procedure
Preparation for nerve repair microsurgery covers what you do in the days before, the tests your medical team will run, and the steps on the day itself. Your surgeon's instructions take priority over any general guidance.
In the days before surgery, most patients are asked to stop taking blood thinners and anti-inflammatory medications for a period their doctor specifies, because these increase bleeding during the delicate microsurgical stitching. Smoking slows nerve and wound healing significantly, so most teams ask patients to stop smoking at least several weeks beforehand. Alcohol should also be avoided in the days leading up to surgery. You will usually be told to stop eating solid food at least six hours before the operation and to stop drinking clear fluids about two hours before, though the exact cut-off times depend on your anaesthetic plan.
Before the date of surgery, your team will typically arrange several assessments to map the injury precisely and confirm you are fit for a general anaesthetic.
- Nerve conduction studies (NCS) and electromyography (EMG), which use small electrical pulses to measure how well the nerve is still working and where exactly it is damaged
- MRI (magnetic resonance imaging) or high-resolution ultrasound to visualise the nerve and surrounding structures
- Blood tests to check general health, clotting ability, and blood sugar levels
- A chest X-ray and heart tracing (EKG) if general anaesthesia will be used and your medical history makes it necessary
On the day of surgery, the steps typically follow this order. The sequence and exact details vary between hospitals and between planned versus emergency cases.
- Arrival at the hospital and identity and consent checks
- Nursing assessment: blood pressure, pulse, temperature, and confirmation that fasting instructions were followed
- Marking of the affected limb or body area by the surgeon
- Placement of an intravenous (IV) drip in the arm for fluids and medications
- Administration of general anaesthesia, or in some cases a regional nerve block (an injection that numbs only the arm or hand) combined with sedation
- A tourniquet (a cuff that temporarily stops blood flow) is often applied to the limb to keep the surgical field clear
- The surgeon makes an incision over the damaged nerve and examines it under the operating microscope
- Damaged nerve ends are trimmed back to healthy tissue
- The nerve ends are stitched together directly, or a nerve graft is positioned and stitched in place if the gap is too large
- The wound is closed in layers and dressed; the limb is splinted to protect the repair
- You are moved to the recovery room and monitored as the anaesthetic wears off
Aftercare
Recovery from nerve repair microsurgery is measured in months, not days, because nerves regrow at roughly one millimetre per day and the target muscles must wait for those signals to arrive. Most patients spend at least one night in hospital, and some need longer depending on the complexity of the repair and their general health.
- The repaired limb is held in a protective splint or cast for several weeks to prevent tension on the repair; your surgeon will decide the exact duration
- Physiotherapy (physical therapy) begins early, often while the splint is still on, to keep joints mobile and prevent stiffness
- The wound or graft site is checked for signs of infection at each follow-up visit; dressings are changed as directed by the nursing team
- Occupational therapy helps retrain the hand and fingers to interpret new nerve signals, which often feel different from normal sensation at first
- Feeling usually returns before movement, and both recover slowly over months to years; your surgical team will track progress with clinical tests
- Nerve conduction studies or EMG may be repeated at intervals to measure whether the nerve is growing back as expected
- Avoid heavy lifting, gripping, or any activity that strains the repaired area until cleared by your surgeon
- Protect the affected hand or limb from heat, cold, and sharp objects, because reduced sensation makes burns and cuts easy to miss
- Smoking delays nerve regrowth and wound healing; continuing to avoid it after surgery gives the repair the best chance
- Some patients need pain management support or psychological support, particularly when recovery is slower than hoped
Cost & What Determines It
The cost of nerve repair microsurgery varies widely because the procedure ranges from a relatively short repair of a single small nerve to a many-hour reconstruction involving multiple nerve grafts, and because hospital fees, surgical fees, and support costs differ greatly between countries and between public and private facilities.
- Severity and complexity of the nerve injury: a simple end-to-end repair costs less than a reconstruction requiring nerve grafts harvested from a donor site
- Number of nerves involved: injuries to several nerves at once require longer operating time and more resources
- Hospital class and country: a private specialist centre in a high-income country charges more than an equivalent facility in Southeast Asia
- Length of stay: complex repairs or post-operative complications extend the hospital stay and add daily room and nursing fees
- Operating theatre time: microsurgery often runs several hours, and theatre time is billed by the hour at most hospitals
- Use of specialised microsurgical equipment, including disposable sutures finer than a hair, the operating microscope, and single-use instruments
- Post-operative splints, casts, or custom-made orthoses (supportive devices for the hand or arm)
- Physiotherapy and occupational therapy sessions, which may run for many months after surgery
- Nerve conduction and EMG studies before and after surgery
- Anaesthesia fees, which depend on the duration of the procedure
Hospital packages for nerve repair microsurgery typically include the surgeon's fee, anaesthesia, operating theatre charges, and a set number of inpatient nights. Items commonly billed separately include physiotherapy sessions, outpatient follow-up consultations, splints or orthoses, and repeat nerve studies during recovery.
BPJS Kesehatan and most Indonesian private health insurance policies do not cover treatment received abroad, so patients who travel overseas for this procedure generally pay out of pocket or rely on international private health insurance that explicitly covers medical travel. Before travelling, request a written cost estimate from the hospital that itemises every expected charge and states clearly what happens financially if the operation takes longer than planned or if a complication requires additional care. A written estimate is the most reliable way to avoid unexpected bills.
Frequently Asked Questions
How long does nerve repair microsurgery take?
The operation usually takes between two and six hours, depending on how many nerves are injured and where they are located. A single clean cut to one nerve is faster to repair than multiple damaged nerves or those that require a graft, which is a small piece of nerve tissue used to bridge a gap. Your surgeon will give you a clearer estimate once they have reviewed your scans and examined the injury.
Will I be asleep during the operation, and how much pain should I expect afterward?
Most nerve repair procedures are done under general anaesthesia, meaning you will be fully asleep, though a regional nerve block, which numbs only the arm or hand, is sometimes used instead. After surgery, some pain and throbbing around the wound are normal for the first few days, and doctors typically manage this with prescribed pain relief. The discomfort usually settles within one to two weeks as the tissues heal.
How long does recovery take, and when can I go back to work?
Initial wound healing takes around two to four weeks, but nerve regrowth is a much slower process that can continue for several months to over a year. Most people with desk-based jobs return to light work within a few weeks, while those doing physical or manual work may need to wait several months and complete a course of physiotherapy first. Your surgeon and physiotherapist will set milestones based on how your recovery is progressing.
How much does nerve repair microsurgery cost?
The cost depends on several factors specific to your case, including the complexity of the nerve injury, whether a nerve graft is needed, the length of your hospital stay, and the class of hospital you choose. Procedures involving multiple nerves or long grafts generally take more theatre time and specialist resources, which affects the final figure. Requesting a written estimate directly from the hospital is the most reliable way to get a number that reflects your exact situation.
