(1) Less traumatic surgery: Compared with conventional open surgery, minimally invasive spine surgery has smaller incisions and significantly less damage to the paravertebral muscles. Conventional open surgery requires extensive stripping and retraction of the muscles of the low back, and sometimes the thoracic and abdominal cavities, which is very traumatic for the patient, while minimally invasive spine surgery is significantly less traumatic than conventional open surgery. (2) Satisfactory efficacy: Studies have shown that many patients with conventional open surgery do not experience significant postoperative pain relief in the low back, and postoperative magnetic resonance examination reveals significant edema and scarring of the muscles of the low back for a long time after surgery, which is mainly caused by excessive damage to the soft tissues of the paravertebral muscles as a result of open surgery. Minimally invasive spine surgery, on the other hand, rarely causes low back pain after surgery because of the small damage to the paravertebral muscles and other soft tissues, with satisfactory results. (3) Fast recovery: Conventional open surgery is more destructive to the structure of the spine and the paravertebral muscles, so it is easy to cause postoperative instability of the spine, and the local pain of the incision lasts longer, which often requires a recovery period of 1 to 3 months after surgery. Minimally invasive spine surgery, on the other hand, has a faster recovery because it causes less damage to the spinal structures and soft tissues of the paravertebral muscles. (4) Less surgical bleeding: Minimally invasive surgery has small exposure and small incisions, so bleeding is also minimal and often does not require blood transfusion, which is beneficial to the patient’s recovery. (5) Small skin incision, small scar, and more beautiful appearance: The incision of conventional open surgery of lumbar spine is usually 10~15 cm, sometimes even longer, and with the reaction of sutures, the scar is often very large, and after healing, it looks like a big centipede, which seriously affects the beauty, especially for women who love beauty, and is often difficult to accept. Minimally invasive surgery, on the other hand, the incision is generally 2~5 cm, and the cosmetic suture method can also be used, with a small postoperative scar, which is very beneficial to aesthetics. (6) Short hospital stay and reduced medical costs: Minimally invasive spine surgery has a short hospital stay and patients can return to work earlier, thus saving limited medical resources. (7) Easier remedy in case of disease recurrence and relapse: Whether minimally invasive surgery or open surgery, recurrence and relapse may occur after surgery, while minimally invasive surgery is simple and effective when operated again because of less damage to the spine and tissues. In contrast, if extensive exposure, laminectomy, or spinal fusion is done, reoperation is very difficult and less effective.
