The great problems with OPAA surgery that the surgeon faced during surgery is how to excised the OPLL as it adhert to underlying dura, make the risk of dural tear and neural injury is high

Thanks for your reply, Ghazwan Hasan sir, I want to know any thermal injury concerns during spine surgery?

I think, you mean anterior approach. There are three problems during the surgery. Abnormal bleeding from the OPLL resection, dural adhesion and spinal cord damage during the removal of OPLL. Surgical strategy is very important. The first discectomies should be completed and reached to bottom of PLL. Then vertebrae should be removed with high speed drill till to the same level of PLL and stopped. Bone wax helped to control bleeding every step. Dura can easily find both far lateral sides of lower disc removing OPLL. Because PLL is least thin in this area. With helping number one Kerrison rongeur, PLL is removed from this point till to reach upper disc level both sides. Then free OPLL is removed by pulling to outside. İf there is adhesion please leave it OPLL by reducing it sızes(free floth).

Ali Fahit Ozor... Is there any thetmal damage due to the high speed drill?

If you use it properly, never cause any damage.
