Extra protective materials are usually added to the mix in neurosurgical operations, such as carrying out brain surgeries. One of those materials is called cranial mesh. It's commonly known as a cranial implant or cranial prosthesis. A cranial mesh implant is a neurosurgical device used to restore skull defects. Various types are used based on the patient's individual requirements. Common types include:
PMA copolymer mesh
PMA copolymer mesh is a non-resorbable cranial mesh. Because it cannot be absorbed, it will always remain in its position for many years to come unless surgical intervention is recommended to remove it. This type of cranial mesh is made from PMMA and acetyl copolymer. These compounds are well known and routinely used in medicine because they are biocompatible, transparent, and relatively easy to fabricate. Depending on the patient's requirements, doctors use this type of cranial mesh for structural support and cranial contouring.
Titanium mesh
Titanium PMA mesh is a type of cranial mesh that is made from titanium and a copolymer called PMA. Titanium is well-recognized for its high strength-to-weight ratio. This makes it an optimal choice for neurosurgical applications. The mesh provides structural support and aids in the repair and regeneration of skull defect tissues.
Biocomposite mesh
A biocomposite mesh is non-resorbable. Like the meshes before, it cannot be absorbed. They are long-term implants that integrate into the surrounding bone. Biocomposite cranial meshes are typically made from polymers reinforced with bioactive glass or ceramic materials.
Allograft bone graft mesh
This type of mesh is a bone graft made from human bone tissue obtained through donation. Allograft mesh implants are biocompatible and promote new bone growth. This makes them widely suitable for those who want to repair cranial defects and encourage natural healing.
Stereolithography (SLA) mesh
An SLA mesh is a digitally fabricated cranial implant made from several imaging databases. SLA cranial meshes are created from a process known as stereolithography. It's an additive manufacturing technique that utilizes resin cured by ultraviolet light. The process is derived through computerized tomography scans and magnetic resonance imaging of the patient.
Polymer mesh
A polymer mesh is made from medical-grade polymers such as polyether ether ketone and polypropylene. Due to their flexibility and high strength, these polymers provide a lightweight and durable solution for cranial repairs. Polymer meshes are frequently used in reconstructive surgeries because of their ability to endure a variety of biological environments.
A cranial mesh is designed for different roles in the medical world. The nature of the defect determines the role a cranial mesh will play. So, to make sure the mesh fulfills its task in neurosurgeries, several factors are taken into consideration. These factors include, but are not limited to, the material kind, porosity, expansion, and overall dimensions.
The mesh materials from above are manufactured in various shapes and sizes according to each patient's needs. Most are customized based on the patients' scan data to ensure a perfect fit. Porosity allows bone tissue to grow into the mesh while supporting the cranial shape. This leads to the restoration of normal brain contours and protection. Some meshes, like SLA and PMMA, consist of high-precision geometries, which improve their structural strength and aesthetic value.
The resorption rate of the cranial mesh can be high, moderate, or low, depending on the materials it is made of. Resorbable meshes are designed primarily to support fused skull bones temporarily. They are made of materials like polylactic acid and polycaprolactone. In contrast, non-resorbable meshes are composed of materials like titanium and PMMA and include long-lasting support. They are meant to provide permanent structural reinforcement.
Cranial implants are designed to be biocompatible and equipped with minimal foreign body reaction. This means they won't be rejected by the patient's body. Titanium and allograft meshes not only are biocompatible but also promote bone healing or re-growth. This allows for improved integration of the mesh with the patient's native bone tissue. Some meshes contain bioactive surfaces that stimulate bone cell activity.
Lightweight yet rigid and strong is how cranial meshes are designed. They can be easily carried around without the extra weight but are tough enough to protect the brain. Materials like titanium and copolymer offer excellent durability and are weather-resistant. Are you a business owner looking to invest in craniomaxillofacial implants for sale?

The primary goal of cranial meshes is to repair defects that have resulted from neurological surgery either for correctional or treatment purposes. They are also used in skull reconstructions when there is a loss of a portion of the skull due to injury, tumors, or congenital conditions. It's a medical device used in several rehabilitation centers and hospitals. Some of the common places among them include:
Neurosurgery centers
Neurosurgery centers usually complete complex brain surgeries that require cranial meshes for protection and support. They use biocompatible materials like titanium and PMMA to make sure the meshes integrate with the skull over time.
Trauma hospitals
Remember those hospitals that were mentioned earlier? Trauma hospitals deal with patients who have sustained severe head injuries. They use allograft and biocomposite meshes to reconstruct the damaged skull. Allografts promote natural healing and are left intact by the body. On the other hand, biocomposites gradually absorb and encourage new bone growth.
Oncology treatment centers
Oncology treatment centers handle brain tumors that require surgical intervention. They prefer using cranial meshes like polymer meshes that facilitate tumor removal. These meshes provide long-term structural support and enhance the patient's recovery process.
Congenital defect correction hospitals
Congenital defect correction hospitals deal with infants and young children with cranial deformities. They use absorbable cranial plates that repair deformities and allow for natural growth as the child develops. They're non-permanent solutions that fit the changing shape of a young patient's skull.
Reconstruction centers
Reconstruction centers for for cranial vault reconstructive surgery also use meshes during primary and secondary cranial vault reconstructive surgeries. They prefer using custom-made meshes from 3D printing technologies like SLA. These assist in achieving the best aesthetic and functional outcome, maximizing protection and contouring for the patient's skull.
To its users, the cranial mesh makes a plethora of specifications available. First off, they're available in different shapes and sizes to accommodate the needs of every patient. They are commonly produced using computer-aided design and manufacturing software. This makes it easy to create customized cranial meshes. The size of the mesh varies depending on its intended use. Typical sizes range from 100 to 300 millimeters in length, 50 to 200 millimeters in width, and 1 to 3 millimeters in thickness.
Porosity is another relevant cranial mesh specification. It usually varies between 1 and 10%. High porosity values improve tissue integration. Low values, on the other hand, provide high mechanical strength. This results in lower chances of mesh deformation. The resorption time of cranial meshes ranges from several weeks to many years. Non-resorbable meshes are designed to provide permanent support. Meanwhile, meshes such as allograft and polymer are gradually absorbed into the bone and soft tissues. This allows natural healing.
And like everything, maintenance is key to achieving long life. There are several ways the lifespan of cranial meshes can be extended. They've got to be handled with utmost care to avoid damage during storage and transportation. Manufacturers should consider storing them in protective cases or packaging so no dirt gets into them. Clean them using non-abrasive, low-residue wipes or cloths to avoid disturbing the mesh structure or harming the surface. Avoid using chemical solvents that may cause wear and tear. After it's been cleaned, visually inspect it for any signs of wear, tear, or deformation. Only use it if it's still viable.
Although cranial meshes are permanent, there are cases where meshes need to be removed. This is done when there's mesh infection or exposure. Overall, the maintenance practices of cranial meshes are slightly different from standard surgical implants. This is because the former often have specific guidelines for handling, storage, and removal of meshes.
Business owners looking to invest in durable ***cranial implants*** need to do a lot of research. Go for materials that can blend in with the skull bone and have minimal deformation. These include titanium and copolymer meshes. Ensure the porousness is ideal for optimum biological fluid exchange and mechanical integrity.
