The incision is centered over the involved vertebra. This can be verified by image intensifier.
The length of the incision depends on many factors eg, number, location and pathology, obesity of the patient, previous thoracic operations, etc.
Thanks to magnification (loupe and microscope), illumination, and table mounted retractors, the incision is typically much smaller than the traditional incision. However, to better show the anatomy, we will here show the traditional one.
It is necessary to confirm the correct level of the approach with fluoroscopy.
