For the convenience of clinical work and improvement of surgical operation method,protecting vital structure,improve the safety of the surgical operation,extend the orientation of operation and reduce operation complications in jugular foramen region by far-lateral approach.

Objective To observe microsurgical anatomy of anatomical landmarks concerning to suboccipital far lateral approach.

Methods and results:Five adult cadaveric head specimens with arteries and veins perfused with colored latex were dissected by using microsurgical skill, according to the procedures of the far lateral approach.

PART I Microanatomical and Radiographic study of Suboccipital Far Lateral ApproachThe suboccipital far lateral approach( FLA ) is being increasingly used to access lesions ventral to the brainstem and cervicoraedullary junction.

Microsurgical treatment via lateral fissure approach for hypertensive basal ganglia hematoma;

Treatment of spinal metastases by posterolateral approach;

Extensive posterolateral approach for the treatment of thoracolumbar central disc herniation;

Objective:To assess the safety and efficacy of surgery which accomplished corpectomy,interbody fusion with allograft bone and posterior instrumentation via single posterolateral approach in the thoracolumbar metastasis,in which tumor extending into the spinal canal, the bilater pedicles or the paravertebral areas.
