Cci first or tethered cord first

Hi Dr. Centeno, I have been diagnosed with both Cci and tethered cord by a neurosurgeon. I’m uncertain about which condition should be addressed first. What would you recommend? I’ve heard that releasing the tethered cord might further loosen the cervical area, but I’ve also heard that treating CCI first could potentially worsen tethered cord symptoms. I would really appreciate your guidance on the optimal order of treatment.
