What Is Minimally Invasive Surgery?
It is a surgery in which the operation’s impact is minimised by reducing the incision size as well as the size of the instrument used to carry out the procedure

The field of surgery is being redefined by Minimal invasive surgery (MIS). Several surgeries as well as diagnostic procedures are described by this term. A surgeon needs to make a big incision in traditional surgeries in order to operate. Through MIS, the surgeon makes a few tiny holes – normally less than half an inch. After that, he inserts specially designed (Endoscope), fine instruments and advanced video equipment to carry out the operation through the smaller openings. Tumours that are large can be removed as well through small openings (microcraniotomy).

Neurosurgeons use minimally invasive surgery. Non-invasive treatments are used by neurosurgeons whenever these techniques can achieve equivalent or better results in comparison to standard open surgical procedures. Sophisticated minimally invasive neuronavigation technology minimises incisions frequently allowing surgeons to cosmetically hide scars.

Conditions:

a) Micro Craniotomy
The surgical removal of fragment of the bone from the skull for exposing the brain is called craniotomy. The part of bone called the bone flap is removed using specialized tools. Temporarily, the bone flap is removed, then substituted after the brain surgery has been carried out.

b) Neuroendoscopy are the endoscopic approaches to brain surgery. It can be used for the diagnosis and treatment the following problems:
• Aqueductal stenosis causing Hydrocephalus
• Brain tumours: cysts, Intraventricular Brain tumours, Intraventricular Colloid cyst
• Endonasal, transphenoidal removal of pituitary tumour.
• Endonasal removal of meningioma.
• Craniopharyngioma

c) Stereotactic biopsies of the brain tumours
Stereotactic neurosurgery is brain mapping in a 3-D coordinate system. Neurosurgeons can accurately target any brain area in stereotactic space (3-Dimensional coordinate system) using CT scans, MRI and 3-D computer workstation. A minimally invasive procedure using this technology to obtain brain tissue samples for the purpose of diagnosis is called stereotactic brain biopsy.

Benefits of Minimally Invasive Procedures
1) Less Pain
Less post-operative pain and discomfort are caused by MIS procedure. Research has shown less pain being reported by patients undergoing MIS procedures. Also, these patients require smaller pain relievers doses that patients undergoing traditional surgeries.

2) Shorter Hospital Stay
Hospital stay is shorter and patients can return to normal activities quicker. Patients undergoing MIS procedures are generally able to go home sooner.

3) Less Scarring
Smaller incisions are required in MIS procedures. Therefore the resulting scars would be smaller and less noticeable. The scars formed as a result of MIS have a less serrated appearance, thus looking pleasant.

4) Less Injury to Tissue
A majority of traditional surgeries require a long incision. Usually, this incision is needed to be made through the muscle. A remarkable time is needed for the muscle to heal after surgery. There is less tissue damage and faster recovery due to the absence of long incisions in MIS and surgeons frequently don’t have to slit through the muscles to complete the procedure.

5) Higher Accuracy Rate
A greater accuracy rate for the majority of procedures. The surgeon has improved vision and magnification of internal organs as well as structures since MIS procedures make use of video-assisted equipment. Not every MIS procedure or surgery may be suitable for each patient. Your personal options will be discussed by your surgeon before any surgery.
