What Is Keyhole Surgery?
Keyhole neurosurgery refers to microsurgery or endoscopic assisted microsurgery through a small bone window (2-3 cm in diameter) in place. Use small bone windows to reveal large lesions deep in the skull.

- Keyhole neurosurgery refers to microsurgery or endoscopic assisted microsurgery through a small bone window (2-3 cm in diameter) in place. Use small bone windows to reveal large lesions deep in the skull.
- Early 20th Century,
- 1. Small bone windows reveal large deep lesions in the skull.
- 2. No exposure is the best way to protect normal neurovascular structures.
- 3. Carefully formulating a surgical plan before surgery is the key to successful surgery, including reviewing medical history, physical examination, neuroimaging data and laboratory examinations, and developing individualized surgical methods and surgical approaches, including the patient's position, skin incision, Bone window location, dural incision, intracranial subarachnoid approach, etc.
- 4. The inner plate of the bone window edge is ground at an obtuse angle to expand the exposure range.
- In addition to surgical microscopes and general surgical instruments, it also includes: 1. Endoscopes: gun-shaped hard endoscopes with a diameter of 2 ~ 4mm and a length of 10 ~ 15cm. The angle of view of the objective lens is commonly used at 0 °, and those who are 30 ° ~ 110 ° are reserved as appropriate; 2. Cold light sources, cameras and monitoring screens; 3. Mechanical or pneumatic flexible shaft endoscope fixing devices; 4. Special equipment: Endoscope-assisted microsurgery Special instruments such as Perneczky-Zeppelin aneurysm clamp, knife, scissors, stripper, etc.
- 1. supraorbital keyhole approach.
- 2. Subtemporal approach
- 3. Interhemispheric in the cerebral hemisphere.
- 4. Transcortical transventricular keyhole approach.
- Due to the in-depth study of microanatomy and surgical approach, the development and application of neuronavigation and endoscope technology, and microelectromechanical systems (MEMS), neurosurgical craniotomy and bone windows will be more miniaturized and individualized.
