Introduction:
Symptomatic thoracic disc herniations (TDHs) are uncommon and can be surgically treated. Although transthoracic decompression is considered the gold standard, it is associated with significant comorbidities. In particular, approach via a posterior laminectomy has been associated with poor results. Several strategies have been developed for the resection of TDHs without manipulating the spinal cord. We describe a minimally invasive technique by using 3-D navigation and tubular retractors with the aid of a robotic holder via an oblique paraspinal approach.
Materials And Methods:
The 20-mm working tube via an oblique trajectory through the fascia provides a good surgical field for thoracic discectomy through a microscope. We present our first five patients with TDHs operated using this minimally invasive approach.
Results:
Neurological symptoms were improved postoperatively, and there were no surgical complications. There was no instability or recurrence during the follow-up period.
Conclusion:
The oblique paraspinal approach may offer an alternative surgical option for treating TDHs.
