While most skull base tumors are primary and found to grow inside skull, there are some which are secondary and spread to the brain from other parts of the body. Neurosurgery treatments for skull base tumors and conditions are challenging mostly because they are quite often located close to critical blood vessels and nerves in brain. In some specific cases skull base tumors can be removed through neurosurgery including minimally invasive transsphenoidal surgery through nose or through small incisions behind the ears or within eyebrows. Although there are no obvious causes for development of skull base tumors, specific genetic conditions, radiation therapy to head and exposure to certain chemicals are found to increase risk of having these brain tumors.
The four most common types of skull base tumors are listed below.
Meningioma – These brain tumors are usually benign and arise out of coverings of brain. Representing almost 33 percent of all primary brain tumors, meningiomas are most frequently found to occur in middle-aged women. Although meningiomas are most often found near top and outer curve of the brain, they are sometimes also found at the base of the skull.
Pituitary Adenomas – Brain tumors arising from the pituitary gland are known as pituitary adenomas and pituitary carcinomas. Pituitary adenomas are slow-growing noncancerous masses which represent about 10 percent of all primary brain tumors. Most often growing in front of the pituitary gland, pituitary adenomas can either be ‘secreting’ or ‘non-secreting’ masses. Pituitary carcinomas are however malignant but are found to rarely occur.
Rathke Cleft Cyst – These are noncancerous fluid-filled cysts developing between parts of the pituitary gland at the base of brain. Rathke cleft cysts are congenital deformities and develop when the fetus is still growing. However, these are rare and hardly cause any symptoms or problems in children. Quite often they are only found in adults when they are undergoing MRI scan for some other problem. Moreover, females are found to be more likely to develop Rathke cleft cysts in comparison to male children.
Acoustic Neuroma – This is an uncommon slow-growing noncancerous brain tumor which develops upon the main nerve leading from inner ear to brain. However, acoustic neuroma can cause ringing and hearing loss in ears along with unsteadiness as this nerve directly influences hearing and balance. Acoustic neuroma is also known as vestibular schwannoma. In some cases this brain tumor may grow rapidly to become large and press against brain tissue so as to interfere with vital functions. Neurosurgery and radiation therapy are the best treatment options for acoustic neuroma.
Neurosurgery in India is an excellent opportunity for international patients seeking affordable healthcare solutions in other countries. Neurosurgeons in India are recognized as some of the best doctors globally and are well experienced so as to perform the most complex operations. Apart from high quality of treatments, neurosurgery costs in India are in fact just a fraction of what overseas patients may have to pay for similar procedures in the developed countries. International patients therefore can save substantial amounts of their hard earned money without compromising on the quality of treatment by undergoing neurosurgery in India.
