Transsphenoidal surgery is a type of surgery in which an endoscope or surgical instruments are inserted into part of the brain by going through the nose and the sphenoid bone (a butterfly-shaped bone forming the anterior inferior portion of the brain case) into the sphenoidal sinus cavity.
An endocrinologist is only involved in preparation for an endoscopic endonasal surgery, if the tumor is located on the pituitary gland. The tumor is first treated pharmacologically in two ways: controlling the levels of hormones that the pituitary gland secretes and reducing the size of the tumor. If this approach does not work, the patient is ...
The surgery is used to treat various brain cancers, benign, and functional disorders of the brain. [1] This is sometimes combined with whole brain radiotherapy, and a 2021 systematic review found this combination led to the greatest improvement of survival for those with single brain metastasis.

In 2015, researchers at the Cleveland Clinic in Ohio used population-based data of the Central Brain Tumor Registry of the U.S. to calculate an incidence of 10.9 per million of population, or about 3,300 cases of VS per year. A higher incidence up to 29.3 per million of population was found for the 65-74 year-old age group.
This surgical approach is typically performed by a team of surgeons, including a neurotologist (an ear, nose, and throat surgeon specializing in skull base surgery) as well as a neurosurgeon. In this approach, the semicircular canals and vestibule , including the utricle and the saccule of the inner ear are removed with a surgical drill ...
The scientists also found cancer lesions in a second skull from the Duckworth collection. Labeled E270 and dating from 664 BC to 343 BC, it belonged to an adult woman who was at least 50 years old.
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
The male skull had a large lesion surrounded by 30 or so small metastasized lesions around it. To their great surprise, researchers found cut marks around the lesions.
