Do You Know About The Long-Term Side Effects of Craniotomy?

A craniotomy is a surgical procedure that involves removing a portion of a skull that gives access to the brain for an extended period, it is continuous monitoring and treatment of this condition such as severe head injuries, and there are some long-term side effects of craniotomy. When brain surgery is performed, the neurosurgeon makes an incision in the scalp or removes a section of the skull bone (craniotomy), and then carefully retracts the brain tissue that he accesses in this affected area.  

In 2022, 20,414 adult patients experienced Craniotomy for tumor restriction. Identified 20.8% of patients sustained one or more postoperative complications. The most frequent complications; were unplanned 30-day- readmission (9.60%), venous thromboembolism (*3%), and total surgical site infected (2.25%). 

In this blog, we understand the long-term side effects of craniotomy. 

What is Craniotomy? 

A craniotomy is a very deadliest condition and doctors also have to take great care. It is a medical procedure in which a part of the skull is removed to allow access to the brain. During this procedure, it is advisable to have experienced doctors or specialized tools to remove the section of bone, known as a bone flap. After the surgery, the bone flap is typically replaced in its original position.

The craniotomy technique is a complicated process that sometimes doctors must take the assistance of computer systems, MRI, or CT scans to make sure that we get access to the precise area of the mind we need to treat. When the mind is visible, the health care professional can perform important approaches, which include eliminating a tumor or repairing broken blood vessels. During this time, the affected person’s critical signs and symptoms and mind characteristics are continuously monitored to ensure safety.

Key Features of Craniotomy

Craniotomy treats various medical conditions that can affect brian. These are some of the features that require craniotomy include:

Brain Tumors: 

A craniotomy is performed when a tumor within the brain needs to be removed from the skull. The tumor can be either benign (non-cancerous) or malignant (cancerous), and the surgical approach aims to remove as much of the tumor as possible while ensuring optimal treatment.

Swelling and Inflammation:

Post-operative swelling and contamination can persist for a long time, causing strain on the brain and leading to signs and signs consisting of complications, seizures, or cognitive impairment.


Infections, which include meningitis or abscesses, can occur following surgical operation and may cause lengthy-time period complications if no longer appropriately handled.

Brain Bleeding:

Hemorrhage during or after surgical operation can result in prolonged-term neurological deficits if now not nicely controlled.


Scar tissue formation in the thoughts can intrude with ordinary mind features, leading to signs and symptoms and symptoms like seizures or sensory disturbances.

Precautions of Long-Term Side Effects of Craniotomy

A craniotomy is a surgical operation wherein a portion of the skull is briefly removed to get the right of entry to the brain. While it’s frequently vital for various medical situations which include mind tumors, worrying brain injuries, or vascular abnormalities, the system isn’t always without our capacity for long-term facet results. Patients who go through long-term side effects of craniotomy can also face numerous challenges and precautions related to the aftermath of the surgical operation. Here, we can discover some of the precautions related to the long-term side effects of craniotomy.

Regular Follow-up Visits:

Avoid sports that would potentially harm the surgical web page, together with touch sports or heavy lifting, especially all through the initial healing length.

Observing Cognitive Changes:

Identify any changes in cognitive factors, including loss of memory, concentration, changes in mood or behavior, and communicate them together with your healthcare workplace organization

What Things Happen During a Craniotomy?

When the damaged tissue is addressed the skull bone is usually replaced and repaired using plates, screws, or wires. After following the procedure, patients suffer some long-term side effects of craniotomy symptoms such as headache, nausea, weakness, or changes in cognitive function as their brain adjusts before surgical intervention and healing. Long-term monitoring and follow-up care are necessary to ensure optimal recovery and management of any complications. 

Cognitive Modifications:

This can include difficulties with Reminiscence, Attention, and Trouble-Fixing Talents. Along with emotional adjustments post-surgery, a person can also even revel in modifications in their day-to-day behavior, because of the effect on the capacity to think. One may revel in difficulty in communication, and concentrating, and even suffer reminiscence loss, which could impact a person’s persona and mannerisms.

Motor feature impairment:  

Weakness or paralysis in one facet of the body, coordination issues, or difficulties with quality motor competencies.

Sensory Adjustments:

Loss of sensation, altered sensation, or modifications in vision or hearing.

Emotional and mental consequences:  

Mood swings, despair, tension, or personal modifications. Neuroscience nurses who take care of craniotomy patients often see transient alterations in conduct, mind, and personality just like the ones taking place after a minor head harm or subarachnoid hemorrhage. These adjustments might also result in melancholy and alter one’s own family dynamics.


Some people can also broaden epilepsy or revel in recurrent seizures after a craniotomy. Craniotomy with surgical resection is the main treatment of primary brain tumors. Different studies have reported varying rates of post-craniotomy seizures, ranging from 1.1% to 29%. These variations in rates may be attributed to differences in the patient populations included in the studies.

Learn about the Common Seizure Symptoms and Their Causes


Chronic headaches or migraines can also persist following surgical procedures. The headache and different signs, including nausea, typically arise within 24 – 48 hours after the epidural but can arise at any time within 12 days. The signs and symptoms may work away without remedy within 14 days.

Some types of Craniotomies can be life-threatening. Your surgeon will explain these risks and work with your healthcare team to save you from any headaches affecting you after your surgery. The possible risks and complications of a Craniotomy.

  • Brain swelling
  • Bleeding.
  • Seizures
  • Pain.
  • Hematoma.
  • Stroke.
  • Unstable blood and sugar level
  • Some risks associated with the use of general anesthesia
  • Muscle weakness
  • Hydrocephalus.
  • Infection.
  • Headaches.

Some complications are rare and usually associated with specific areas of the brain, so they may or may not pose an honest risk for some individuals.

Reasons Behind Undergoing Craniotomy Procedure?

There may be some reasons why your doctor may recommend a Craniotomy procedure. A craniotomy is a surgical treatment achieved for various medical reasons, typically related to the elimination or remedy of a mind lesion. The decision to perform a craniotomy is based on specific medical conditions that necessitate direct access to the brain. Here are a few common reasons why a craniotomy process might be necessary:

Brain Tumor:

A brain tumor is usually reduced to take away a mind tumor or for biopsy. Access to the mind is essential for proper identification and removal of atypical tissue.

Treatment of Aneurysms:

In cerebral aneurysms wherein there can be a smooth spot inside the blood vessel wall that may rupture, a craniotomy can be important to get admission to and restore the aneurysm. 

Traumatic Mind Harm:

Severe head injuries may also require a craniotomy to manage inflammation, renal bleeding, or other distressing side effects. By neuro surgically removing a portion of the skull, a neurosurgeon can relieve stress and provide appropriate treatment.

Abnormal Blood Vessels:

Abnormal blood vessels in the brain, such as arteriovenous malformations (AVMs), may additionally require surgical operation through craniotomy to accurately address the trouble.

What are the types of Craniotomy? 

Burr hole Craniotomy:

This manner includes drilling a small hole into the skull with the usage of a specialized device called a burr hole. Burr holes are normally used for minimally invasive methods, which consist of placing electrodes for deep concept stimulation or draining extra cerebrospinal fluid.

Keyhole Craniotomy:

Similar to a burr hole, however barely large, keyhole craniotomies offer greater access to the mind on an equal time but minimize the dimensions of the incision. This technique is regularly used for techniques like tumor removal or the clipping of cerebral aneurysms.

Minimally Invasive Craniotomy:

Minimally invasive strategies include small incisions and specialized instrumentation to improve the mind’s right of access with minimum harm to the surrounding tissue. These procedures reduce the risk of headaches and may result in faster recovery times compared to standard open surgeries.

Decompressive Craniotomy:

In cases of traumatic brain injury, stroke, or other conditions causing increased intracranial pressure, surgeons may perform a decompressive craniotomy. This approach includes casting off a part of the skull to alleviate stress in the mind and prevent additional damage.

Frontal Craniotomy:

The surgeon accesses the frontal lobes of the mind by making an incision in the brow. Surgeons commonly perform frontal craniotomies for procedures involving the frontal cortex, such as tumor removal or epilepsy treatment.

Temporal Craniotomy:

This technique accesses the temporal lobes of the thoughts through an incision made above the ear. Temporal craniotomies are applied for approaches associated with the temporal cortex, consisting of epilepsy surgical treatment or the removal of temporal lobe tumors.

Occipital Craniotomy:

Surgeons gain access to the occipital lobes of the brain by making an incision in the back of the head. They perform occipital craniotomies for procedures related to the occipital cortex or for lesions located in the posterior part of the brain.

Pterional Craniotomy:

This technique accesses the location across the sphenoid bone, typically through an incision made above the ear and lengthening inside the direction of the temple. Typically, surgeons use pterional craniotomies for procedures such as aneurysm clipping, tumor removal, or accessing lesions within the anterior and middle cranial fossae.

Each shape of craniotomy has its symptoms and signs, benefits, and functionality dangers, and the selection of method is primarily based totally upon elements along the region and nature of the pathology, the affected man or woman’s regular fitness, and the medical doctor’s information.

Frequently Asked Questions

What is the recovery period for a craniotomy?

The recuperation time for a craniotomy can vary depending on numerous factors, such as the volume of the surgical treatment, the affected person’s easy fitness, and any complications that would occur. In fashion, patients also can spend six to eight within the hospital after the device, and then several weeks to months convalescing at home. 

What is the average survival rate of a craniotomy patient? 

In 2020 The mortality fee following craniotomy is 1.2% and the morbidity charge is around 8-12%. In 2022 it became the 30-day survival rate for infratentorial craniotomy for brain metastasis became 100%; at 180 days, the survival fee turned to 80%. 

What are the long-term side effects of craniotomy?

Neurological deficits – Temporary or everlasting modifications in vision, stability, coordination, power, or cognitive features may result from the surgical procedure.
