A cranioplasty is performed to correct a deformity or defect of the skull. The deformity/defect could be congenital, as a result of trauma or acquired for example after a previous surgery involving the skull. A craniotomy is the most commonly performed surgery for brain tumour removal. It also may be done to remove a blood clot (hematoma), to control haemorrhage from a weak, leaking blood vessel (cerebral aneurysm), to repair arteriovenous malformations (abnormal connections of blood vessels), to drain a brain abscess, to relieve pressure inside the skull, to perform a biopsy, or to inspect the brain. A cranioplasty is a surgical procedure to correct a deformity or defect of the skull and it is usually performed following a traumatic injury to the skull or after a previous brain surgery such as a craniotomy or craniectomy. In order to correct the defect the physician may have to use a prosthetic or other synthetic surgical material to complete the procedure.
The surgical procedure cranioplasty is performed to correct a deformity or defect of the skull. It is undertaken only after the neurosurgeon and the family accept the fact that there is a clinical issue involved due to the deformity and needs to be corrected.. There are a variety of surgical materials and prosthetics used for a cranioplasty. Your child’s neurosurgeon will review what materials will be used for your child’s specific cranioplasty procedure.
A craniotomy is performed to gain access to the brain for surgery by removing a portion of the skull. After the surgery, the bone that was removed from the skull is usually replaced using sutures or metal plates. An example of a situation where a surgeon may choose to perform a craniotomy is for removal of a brain tumour. A cranioctomy is performed when a portion of the skull is removed and replaced and in craniectomy the portion of the skull is removed but not immediately replaced. Some examples of situations where a surgeon may choose to perform a craniotomy are: to create room for the brain to swell after trauma, to remove the bone due to an infection in the skull or a severely damaged skull with multiple fragments.
Early cranioplasty is helpful for improvement of neurological functions of patients craniotomy helps to correct the skull deformities at young age which can help for rest of the life for the patient. These are precise and farily accurate with minimum incision.
Immediately following craniotomy, it usually takes at least 6 weeks for the bone to completely heal. any activity that may risk a hit to the head or fall are completely prohibited as the skull bone takes long time to heal and any physic injury could be life-threatening. Wearing a protective helmet is recommended. Only gentle washing is recommended. Scrubbing, oiling etc. is to be avoided completely. Patients discharged only when they are able to eat a regular diet, well managed on oral pain-relieving medications and there are no complicating health issues prevailing at the time of discharge. Any a change in the patients behaviour, vomiting episodes, fever, drainage/redness/swelling at the surgical site, seizure and pain are to be observed and doctor must be contacted immediately.
What is the difference between a craniotomy and craniectomy?
Both procedures involve removing a portion of the skull, usually to perform surgery on the brain. The difference is that after a craniotomy the bone is replaced and after a craniectomy the bone is not replaced immediately.
What is the waiting period until the bone flap is replaced?
The bone flap is replaced after adequate time to heal. Your neurosurgeon will decide when the bone flap can be replaced but most often that decision is made when it is safe in order to reduce the risk of infection. Bone flaps are usually replaced 1 - 3 months after the craniectomy.
Will my child need further surgery as the head grows?
Not usually. Your child will have several follow-up appointments after surgery to ensure that everything is healing appropriately. It is usually not necessary to replace the cranioplasty materials as your child grows.
When can the bone flap be stored and replaced? When are synthetic materials necessary?
This is usually decided by your child’s neurosurgeon on a case by case basis. However, if there is infection or the bone was damaged, synthetic materials will usually be chosen for the cranioplasty.
After a cranioplasty Will my child’s head look the same after the surgery as pre-injury?
Your child’s head should have an appearance very similar to how your child looked pre-injury. Your child will still have a scar at the incision for the cranioplasty site.
Brain tumors are abnormal growth or cancers within the brain. Earlier having a brain tumor meant awaiting certain death.
Spine surgery is traditionally done as "open surgery," meaning the area being operated on is opened with a long incision to allow the surgeon to view and access the anatomy. In recent years, however, technological advances have allowed more spine conditions to be treated with a minimally invasive surgical technique.
Endoscopic Spine Surgery is a type of state-of-the-art surgery that uses small tubular system or micro incisions, assisted with an endoscope or microscope. This type of surgery provides patients with quicker recovery and less pain than traditional spine surgery. It preserves normal spine mobility because the spine is not fused with screws and rods.
Surgery for skull base tumours results in a cure for many patients. For most of these patients, traditional open craniofacial surgery is the safest approach with the best chance of success. In recent years, however, endoscopy-assisted surgery, which leaves no visible scars, has been found to be effective for the resection of some skull base tumours.
An Arterio-Venous Malformations (AVM) is a tangle of abnormal and poorly formed blood vessels (arteries and veins), with an innate propensity to bleed. An AVM can occur anywhere in the body, but brain and spinal AVMs present substantial risks when they bleed.
A stereotactic brain surgery is a surgical procedure where lesion, frequently a brain tumour, is removed with assistance of image guidance, that is previously obtained images (usually an MRI) are used to guide the surgeon to the exact location of the lesion to facilitate as accurate a pathway through the brain and safe removal of as much abnormal tissue as pos
Lumbar fusion (Arthrodesis) is a major surgery performed to permanently join together two or more bones in the spine so there is no movement between them. These bones are called vertebrae. A lumbar fusion surgery is designed to stop the motion at a painful vertebral segment, which in turn should decrease pain generated from the joint.
Microdiscectomy, also called Microlumbar Discectomy (MLD), is performed for patients with a painful lumbar herniated disc. Microdiscectomy is a very common, if not the most common, surgery performed by spine surgeons. The operation consists of
Lumbar decompression surgery is a type of spinal surgery performed to treat some conditions affecting the lower back (lumbar spine) that haven't responded to other treatments. The main aim of this type of surgery is to improve problems affecting the legs, such as persistent pain and numbness, caused by pressure on the nerves in the spine.
Lamina is part of the bone that makes up a vertebra in the spine. Laminectomy is surgery to remove the lamina. Laminectomy is also performed to remove bone spurs in the spine. The procedure helps to reduce the pressure off the spinal nerves or spinal cord.
Aneurysm repair is a surgical procedure to correct an aneurysm, a weak area in a blood vessel wall that causes the blood vessel to bulge or balloon out and sometimes burst (rupture). It may cause:-Bleeding into an area around the brain, heart, abdomen-Bleeding that forms a collection of blood (hematoma)
Most patients with neurological disorders are first examined by neurologist who has specialized training in the diagnosis and non-surgical treatment of a wide variety of diseases affecting the brain, spinal cord, nerves and muscles.
Spinal stenosis is a narrowing of the spinal canal, which places pressure on the spinal cord. If the stenosis is located on the lower part of the spinal cord it is lumbar spinal stenosis. Stenosis in the upper part of the spinal cord is cervical spinal stenosis.
Brain surgery is an operation to treat problems in the brain and surrounding structures. Brain surgery may be necessary for patients with a range of neurological ailments. Two of the most common reasons patients require brain surgery are brain tumours and brain trauma. The surgeon makes a surgical cut through the scalp.
Neck pain may be caused by disc degeneration, narrowing of the spinal canal, arthritis, and, in rare cases, cancer or meningitis. There are times when surgery is the best option for treating the medical condition responsible for the neck pain.
Almost everyone will experience back pain at some point in their lives. This pain can vary from mild to severe. It can be short-lived or long-lasting. However it happens, back pain can make many everyday activities difficult to do.
Surgical intervention is the primary treatment for brain cancers (tumours). Such procedures are intricate and need specialised techniques to remove the tumours without causing severe damage. Many benign (non-cancerous) tumours are treated only by surgery.
Spinal cord is a bundle of nerves that runs down the middle of the back. It carries signals back and forth between the body and the brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures or dislocates the vertebrae, the bone disks that make up the spine.
