PLDD Laser Surgery For Herniated Disc
We are accepting patients from all over the world!
PLDD : Percutaneous Laser Disc Decompression
PLDD is an abbreviation of Percutaneous Laser Disc Decompression, a minimally invasive laser treatment performed using local anesthesia for disc herniation, disc protrusion, and bulging disc in selected patients.
Insert a thin needle to the intervertebral disc under the X-ray guidance. Laser fiber is injected through the needle to burn the nucleus pulposus. Laser irradiation makes a heat denaturation and makes a cavity in intervertebral disc, and herniated disc retracts(decompress).
PLDD takes a only around 15 minutes. After surgery, patient needs a rest on the bed for 1 or 2 hours. In this surgery, it's only using local anesthesia. So that the patient doesn't need to be hospitalized. After that, patient can go home on the day, in addition, patient can go back to the normal daily life from the next day.
Theory of PLDD (Percutaneous Laser Disc Decompression)
At the PLDD, send a laser energy to the nucleus pulposus (the core of intervertebral disc), the heat of laser evaporates and burns the soft tissue. It makes a cavity inside of the disc and makes a heat denaturation (thermal denaturation) on the protein tissue. This heat denaturation is a power of shrinking inward. Thereby the internal pressure can be decreased.
Because of these reactions and processes, the nerve root reliefs from the pressure, and the symptoms due to disc herniation be improved.
What is a “heat denaturation”?
If add a heat energy to protein materials, a protein reacts to this heat and changes the properties.
When we cook a baked chicken, this chicken becomes smaller than before cooking, but the total volume of chicken does not change. Only an amount of moisture is decreased by the heat energy, and chicken becomes tighten up and shrinks.
A same reaction happens to the herniated disc at the PLDD. By the heat of laser energy, this heat denaturation happens and herniated disc becomes tighten up and shrinks.
After the herniated disc becomes tighten up and shrinks by PLDD,
the intervertebral space becomes thinner?
If patient undergoes Discectomy surgery, the intervertebral disc is completely extracted. It means that after Discectomy surgery, the intervertebral space is easy to be narrow. Also if put some metallic medical device into the space, there is a possibility that the spine movement gets harden.
However, at this PLDD, there is a possibility that the intervertebral space to be narrow a little bit, but the total volume of disc is not changed. It means that PLDD does not makes the intervertebral space thinner like a Discectomy surgery.
Are there any possibility that the disc herniation relapse after PLDD?
After PLDD, the intervertebral disc becomes stronger than before with reaction of heat denaturation (tighten up and shrinks). Therefore, basically it never relapse.
How long it takes a time to recovery the symptoms?
After the internal pressure of herniated disc has decreased, the disc herniation is getting smaller gradually. But there is an individual differences between each patient in the term of recovery.
If the disc herniation occurred a long time ago, this herniated disc has been harden. In that case, it takes a time or hard to be tighten up or shrinks. But the effect of PLDD occurs steadily, also the disc keeps shrinking for around 6 months after the procedure. Therefore, the postoperative patient needs to be observed for 6 months.

Let's aim for the best goal together!
What I value most is building a strong relationship of trust from patients. As a result of believing so, we have been able to continue medical treatment while receiving great support from many patients to date.
In order to build a strong relationship of trust, it is necessary to remove the pain and distress of the patient.
Not to forget the compassion and delicate attention to eliminate uneasy feelings and dissatisfaction points. I think that it is important for standing in the position of each patients. And also it's important to realize what they are really seeking.
Many patients who have been suffering for many years are coming to our spine center because they have not cured with the treatment so far. Such patients have quite a few concerns and dissatisfaction about medical care.
First of all, I think that it is the job of a doctor to eliminate such feelings. We carefully explain the patient's condition and treatment method and talk repeatedly until we can convince their heart. Then, I would like to aim for the goal to be satisfied together.
