Studies On Microanatomy, Radiography And Clinical Application Of Suboccipital 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. Understanding the anatomy of this region is important for this approach. The purpose of this study was to conduct a morphometric and radiography analysis of the microsurgical anatomy as it pertains to the suboccipital far lateral approach and to evaluate the feasibility and efficacy of a three-dimensional image as a means of obtaining detailed preoperative anatomic information for planning craniovertebral junction (CVJ) surgery. Variations of suboccipital far lateral approaches were then used in patients to improve the operative effect of managing lesions situated in the anterior aspect of the CVJ.OBJECTIVE: The purposes of this study were to examine the microsurgical anatomy as it pertains to the suboccipital farlateral approach, and to compare the three variations----Retrocondylar Approach ( RCA ) , Partial Transcondylar Approach(PTCA) , Extreme-Lateral Transcondylar Approach (ELTCA) ----frequently used in this approach , to supply anatomical basis...
