The anterolateral approach (ALA) enables to access the craniovertebral junction (CVJ), lower and middle clivus, jugular foramen, and cervical spine from a lateral perspective. It is particularly indicated when dealing with extradural bone tumors. Other rare indications are represented by spondylotic myeloradiculopathy and vascular diseases.
We describe here the steps to safely perform an anterolateral approach along with a brief description of its indications and limits.
ALA represents a valid option to treat cervical spine and CVJ bone tumors such as chordomas. Its knowledge can improve the process of approach selection when dealing with such complex cases.
