Guided Laser Surgery Offers Epilepsy Cure (980nm laser)

Approach offers a significantly less invasive alternative to craniotomy, which is currently the most commonly used surgical treatment for epilepsy. For high-risk patients with deep brain lesions, the new technique can be particularly life changing, since a MRI-guided laser probe utilizes a much smaller pathway through the brain to reach the lesion; this reduced the risk of patient complications related to contact with surrounding brain tissue. In addition, the MRI-guided laser probe is inserted through a hole in the skull that is only 3.2mm in diameter, compared to the removal of a larger area of the skull bone for a craniotomy; and since it is a less invasive procedure, recovery time is shorter.

The optical system is based on a continuous wave 980-nm diode laser delivered through a fiber-optic with a one cm diffusing tip. The fiber is housed within a coaxial cooling catheter circulating room-temperature saline to cool the applicator, with the whole procedure taking place within a conventional 1.5 Tesla MRI scanner to provide real-time thermal imaging. The MRI confirms probe placement in the target, and also allows the surgeon to see the ablation of the lesion by the laser heat as it actually happens, with an automatic feedback system that shuts the laser off when the heat approaches nearby critical brain structures.

“ The main use of the MRI guidance is to actually be able to observe the target lesion before the ablation is made, and the position of the laser catheter tip can be exactly imaged by heating up it up by just a couple of degree,” said Angus Wilfong, MD, directly of Texas Children’s comprehensive epilepsy program.” This confirms the position of the catheter tip before continuing on with the ablation. We can also place safety markers on the MRI image to protect sensitive structures from reaching a predefined temperature to avoid damage.”

Five surgeries using the MRI-guided laser probe procedure have been successfully performed at the Texas Children’s Hospital on pediatric epilepsy patients ranging in age from 5 to 15 years old, with widely varied typed of brain lesions. In all cases, patients have been seizure free since surgery and most were released within one to five days.

Semiconductor laser treatment of severe nasal septum

Keywords:Semiconductor laser treatment of severe nasal septum

Treatment of severe nasal septal deviation, the surgical method used in the past, cristae of the nasal septum, surgical correction of condylar moment difficult, prone to mucosal perforation. We used high-power semiconductor laser in the treatment of nasal septum peculiar form cristae, moment-like protrusion 95 patients received satisfactory results. These are as follows.

1.1 General information: 

The group of 95 cases, 61 males and 34 females, aged 18 to 58 years, average 35.7 years old. The main symptoms were 27 cases of unilateral head pain, unilateral nasal obstruction in 54 cases, 8 cases of unilateral epistaxis, hyposmia in 6 patients. History of minimum 3 months, up to 40 years, average 7.4 years. Cristae of all cases of nasal septum, deformity distal condyle moment are in contact with the inferior turbinate, which embedded in the depression inferior turbinate deformity caused by inferior turbinate of 59 cases. Preoperative nasal endoscopy and coronal CT examination of nasal septum, according to prominent ridge, rectangular-shaped protrusion patterns can be classified as "building along the type" 21 cases, "plow-type" 57 cases "osteoma type" in 17 cases.

1.2 Treatment:

All patients with 1% tetracaine hydrochloride in 10ml amount of epinephrine solution plus a piece of cotton soaked anesthesia 2 mucosal surface, the full contraction of the inferior turbinate, and on the surface of latex skin pad. Semiconductor laser output power 6 ~ 8W, pulse method, interval 0. 4s, pulse duration 0. 8 ~ 1. 0s, contact treatment. Guidance in endoscopic sinus surgery, carried out under the TV screen, generally in accordance with the from front to back, bottom-up order, until the cristae of the nasal septum, the basic formation until the moment condyle. Surgery is necessary to observe the contralateral mucosa, so as to not color or change color as the most desirable congestive, note change of white, yellow to prevent change. The group of 79 cases of the former case, change the white in 16 cases, no change in yellow. Laser surgery is generally not as filling, oral Cefradine 3 days, 3 times a day, each time 0. 5g; compound mint Ocean Nasal Spray nasal spray 3 times a day, use for 3 weeks.

Clinical application of percutaneous laser disk decompression

【Abstract】　

Objective

To evaluate the therapeutic effects of lumbar disk herniation treated by semiconductor laser. 

Methods　   

One hundred cases of lumbar disk herniation diagnosed by clinic and CT or MRI within three months 

underwent percutaneous laser disk decompression, including 65 cases of L4-5 and 35 cases of L5-S1 disk. 

Results

In this group of patients, the successful rate of penetration was 100% and the rate of efficiency was 72%. There was no complication in the following 6-18 months. 

Conclusion　

Percutaneous laser disk decompression with semiconductor laser was a convenient, safe, efficient and minimally invasive technique.

PLDD, Percutaneous Laser Disc Decompression

PLDD is the minimally-invasive medical procedure developed by Dr. Daniel S.J. Choy in 1986 that uses a laser beam to treat back and neck pain caused by a herniated disc.

A herniated disc is like a balloon with a weak spot. Inflating it will cause a bulge (herniation). Pain results from the bulge pressing against nerves in the spinal column.

The PLDD treatment is performed on an outpatient basis using only local anesthesia. During the procedure, a thin needle is inserted into the herniated disc under x-ray guidance. An optical fiber is inserted through the needle and laser energy is sent through the fiber, vaporizing a tiny portion of the disc nucleus. This creates a partial vacuum which draws the herniation away from the nerve root, thereby relieving the pain. The effect usually is immediate.

Patients get off the table with just a small adhesive bandage and return home for 24 hours of bed rest. Then patients begin progressive ambulation, walking up to a mile. Most return to work in four to five days.

Because only a thin needle is used, there is no cutting and no scarring. Since only a tiny amount of disc is vaporized, there is no subsequent spinal instability. PLDD is different from open lumbar disc surgery because there is no damage to the back muscle, no bone removal or large skin incision. Most of the complications that may occur with open surgery are eliminated with the PLDD procedure.

Percutaneous Laser Disc Decompression (PLDD)

Percutaneous laser disc decompression (PLDD) is a type of surgery in which a laser probe is inserted into the intervertebral disc space and laser energy applied for achieving decompression and neuromodulation thereby relieving the pain. PLDD is a minimally invasive procedure that falls into the category of percutaneous intervertebral surgeries with the aim to significantly reduce the patient’s pain and recover neurological deficit. It is performed under local anesthesia. By a specially designed laser, with a coefficient of absorbing energy adjusted for soft discus tissue, specific amount of heat is sent to achieve the evaporation of the water from the disc without additional thermal damage thus achieving decompression and creation of a stable intradiscal scar that will prevent herniation from reoccurring.

If you suffer from agonizing back or neck pain as a result of a herniated disc, PLDD (Percutaneous Laser Disc Decompression) offers quick relief without surgery.

Approved by the FDA and recognized by the AMA, PLDD is a minimally invasive laser treatment performed on an outpatient basis using only local anesthesia. During the procedure, a laser beam vaporizes a tiny portion of the disc, decompressing it. Patients typically get off the table and go home. There is no hospital stay, no long recovery period, and PLDD costs many thousands of dollars less than surgery.

Who should consider PLDD?

• This procedure is specifically designed for patients with disc problems accompanied by the following:
• Severe leg, arm, neck or lower back pain.
• Pain that has not responded to six weeks of conservative treatments- rest, meds or physical therapy.
• Herniated lumbar discs confirmed by x-ray studies that may include one or more of the following: Magnetic Resonance Imaging (MRI), CAT Scanning, Myelography, Discography.
