The global epilepsy surgery market size was valued at USD 1,062.6 million in 2022. It is expected to reach USD 1,768.02 million by 2031, growing at a CAGR of 5.82% during the forecast period (2023–2031).
Epilepsy is a central nervous system (neurological) illness. Frequent, unwarranted seizures characterize a chronic neurological condition called "epilepsy." People with epilepsy frequently experience unknown causes of seizures. Although the precise causes of these seizures are still unknown, they could have been triggered by a traumatic event or a previous brain injury. Both adults and children are frequently affected by the disorder, but the risk of infection is higher in the elderly population.
Any head trauma or TBI can cause epilepsy or seizures. Accidents, fall, and unsafe work environments are common causes. According to the Association for Safe International Road Travel 2020, 1.35 million people die in traffic accidents annually, and 3,700 die daily. In addition, according to the Ministry of Road Transport and Highways, India has 11% of all road fatalities despite having 1% of the world's vehicles. Traumatic brain injury (TBI) is the most common reason for epilepsy in people 15 to 24.
Further, depressed skull fractures and penetration wounds often cause seizure disorder. According to the Epilepsy Foundation, 1 in 10 hospitalized TBI patients experienced seizures in 2019. Additionally, 1 in 2 brain injury sufferers experiences post-traumatic epilepsy within a year. Epilepsy risk increases with head injury severity. The CDC estimates that falls will cause 47% of TBIs in 2020, especially in young children and the elderly. Other causes of TBIs include sports-related injuries (21%), blunt force trauma (15%), auto accidents (14%), and violent assaults (9%). TBI killed 61,000 in 2019. Increased traffic accidents and TBIs will boost the global epilepsy surgery market during the forecast period.
Modern technology is used for surgical planning, navigation, and robotic guidance during cranial procedures, saving patients from invasive craniotomy. The benefits of minimally invasive procedures are better patient outcomes, significantly lower complication rates, and shorter hospital stays. A growing number of epilepsy patients prefer epilepsy surgery that uses stereo electroencephalography (SEEG), biopsy, thermal ablation of seizure foci or tumors, Deep brain stimulation (DBS), and surgical treatment of movement disorders. Specialized stereotactic frames were used before computer-guided robotic arms were adapted from the automotive industry for neurosurgical use. To create a basic plan for SEEG, neurologists and neurosurgeons work together under the direction of a noninvasive presurgical epilepsy workup. More than 150 recording sites may be available from a typical montage of 10 electrodes.
Furthermore, there have been few reports of robotic stereotactic assistance in pediatric neurosurgery. The ROSA One Brain Application, a robotic surgical navigation and positioning system for neurosurgical procedures, was approved by the US FDA for Zimmer Biomet in 2019. The company's ROSA Brain portfolio significantly impacted epilepsy surgery because the robot's speed and accuracy make it ideal for intricate procedures in which numerous instruments are inserted into the brain. As a result, the market for epilepsy surgery is becoming more profitable due to hospitals and research facilities' increasing use of equipment for robot-assisted surgery.
Different regulatory processes for neurosurgical devices have led to varying levels of accessibility in various geographical areas. The selection of a control or comparison condition and patient heterogeneity are significant and challenging aspects of clinical trials for neurosurgical devices. An investigation into the various patient pathways, referral, surgical timelines, and surgical and medical treatment options for refractory epilepsy patients referred to Tertiary Epilepsy Clinics in New South Wales, Australia, was published in 2019 in BMC Neurology. Serious complications can arise from temporal lobe surgery in patients with refractory epilepsy.
Despite a significant improvement in freedom from seizures and a higher quality of life with surgery compared to medication, a pediatric study found a 33% rate of serious adverse events. The Epilepsy Society reports that about 30% of patients who undergo temporal lobe surgery discover that the procedure does not end their seizures. Companies looking for regulatory approval of their equipment must adhere to strict standards due to complications, risks, and invasive procedures.
Due to technological advancements, a growing elderly population at risk for seizure disorders, and government initiatives to fund research studies on epilepsy surgery, emerging markets are anticipated to present growth opportunities for global market participants. For instance, engineers at Brazil's University of So Paulo's So Carlos School of Engineering are creating a robot that will be used during surgeries on epileptic children. The researchers developed the new technology using a cutting-edge, 1.6-meter-long, 45-kilogram articulated mechanical arm imported from Germany. In addition, players in the global market compete to offer well-regulated patient services of the highest quality.
Additionally, manufacturers are forming a strategic partnerships with research organizations and top hospitals to provide the tools needed for surgery, maintain the products, and train healthcare professionals. For instance, a study article released in October 2018 discussed the cooperation between US-based healthcare professionals traveling to Hanoi, Vietnam, Vietnamese healthcare professionals traveling to the US, case review, and real-time mentorship using internet-based communication platforms for improved surgical care since 2015. By 2017, Vietnam had performed 40 pediatric epilepsy surgeries. In addition, many of the market's major players are collaborating and signing agreements to launch new products and broaden their product lines.

The global epilepsy surgery market is segmented by procedure type and end-user.
The global market is bifurcated into resective surgery and laser interstitial thermal therapy.
The resective surgery segment is the highest contributor to the market and is expected to grow at a CAGR of 6.85% during the forecast period. In reconstructive surgery, a small portion of the brain is removed. The surgeon removes brain tissue from the brain region that causes seizures, typically where a tumor, brain injury, or malformation is present. Around 70% of patients who undergo temporal lobe surgery discover that the procedure ends their seizures; 20% also report a decrease in seizure frequency. Even after receiving two antiepileptic medications in an adequate dosage for a year, 30% to 40% of patients with refractory seizure disorders require epilepsy surgery. In cases where a patient has epileptogenic foci, reconstructive surgery is performed. The development of stereotactic radiosurgery, MR-guided laser interstitial thermal therapy, and subdural electroencephalogram-guided radiofrequency thermal coagulation has led to newer dimensions in minimally invasive techniques.
Patients with drug-resistant epilepsy, which involves seizures that do not respond to medication, can undergo Laser Interstitial Thermal Therapy (LiTT), a minimally invasive procedure. Some people who experience focal seizures, which start in a particular area of the brain, may benefit from LiTT. An average LITT procedure lasts three to four hours. The FDA and Medicare have approved new MRI-guided Laser Interstitial Thermal Therapy (LiTT) systems for ablation of neurological soft tissue. In addition, according to a study published in August 2020 in PubMed, patients with temporal lobe epilepsy had a pooled seizure freedom rate of 58%, while patients with mesial temporal sclerosis had a rate of 66% after LITT. Approximately 1.2% of Americans have epilepsy, a broad category of neurological conditions that result in seizures, and 0.6% of children between the ages of 0 and 17 have it actively. About 25% of these kids still have trouble controlling their seizures despite taking antiepileptic drugs. The adoption rate of this market is expected to rise due to the high number of epilepsy patients and the higher success rate of LITT.
The global market is bifurcated into hospitals and clinics and specialty centers.
The hospitals and clinic segment is the highest contributor to the market and is expected to grow at a CAGR of 6.66% during the forecast period. According to end-users, hospitals and clinics dominate the world market for epilepsy surgery. This share is primarily attributed to the rise in patients with epilepsy receiving diagnoses and undergoing epilepsy surgery. Patients typically prefer to receive care in a hospital because comprehensive and advanced treatments are available. Clinics are another type of medical facility that treats epilepsy patients. The regions of Europe, the Americas, and developing nations like Russia, China, and India have the greatest concentration of hospitals that provide care for this illness. However, most people cannot afford these costs due to the high cost of diagnosis and treatment, particularly in developing economies. Using prevalence data from the Epilepsy Foundation, between 1.3 million and 2.8 million people have epilepsy (or 5 to 8.4 for every 1,000 people).
