Kocher's Point
Kocher's point is a common entry point through the frontal bone for an intraventricular catheter to drain cerebrospinal fluid from the anterior horn of the lateral ventricles, lateral ventricle. It is located 2–3 centimeters lateral to the midline (at approximately the mid-pupillary line) and approximately 11 cm posterior to the nasion, or 10 cm posterior from the glabella. During cannulation of the Lateral ventricles, lateral ventricle, Kocher's point is landmarked as a point of entry, and care must be taken to be at least 1 cm anterior to the coronal suture to avoid damaging the primary motor cortex. It is most often used to remove cerebrospinal fluid for the treatment of hydrocephalus. See also * Ventriculostomy References

Frontal Bone
The frontal bone is a bone in the human skull. The bone consists of two portions.'' Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word ''frons'' (meaning " forehead"). Structure of the frontal bone The frontal bone is made up of two main parts. These are the squamous part, and the orbital part. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the forehead. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the orbital and nasal cavities. Sometimes a third part is included as the nasal part of the frontal bone, and sometimes this is included with the squamous part. The nasal part is between the brow ridges, and ends ...
