Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
From absolute and relative sizes of the skull the phrenologist would assess the character and temperament of the patient. Gall's list of the "brain organs" was specific. An enlarged organ meant that the patient used that particular "organ" extensively. The number—and more detailed meanings—of organs were added later by other phrenologists.
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 female skull also had a large lesion consistent with a cancerous tumor that led to bone destruction, indicating the person might have been older. There are also two healed lesions from ...
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 ...
Image-guided surgery has been applied to procedures involving on multiple organs such as the brain, spine, pelvis/hip, knee, lung, breast, liver, and prostate. [ 7 ] Part of the wider field of computer-assisted surgery , image-guided surgery can take place in hybrid operating rooms using intraoperative imaging.
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.
This means the brain-to-body mass ratio is, on average, approximately the same for both sexes. [83] [84] Comparing a male and a female of the same body size, an average difference of 100 grams in brain-mass is present, the male having the bigger and heavier brain. This difference of 100 grams applies over the whole range of human sizes.
