Conventional posterior approaches often require facet joint resection and fusion, risking spinal instability. This study summarizes the authors\u2019 experience with a lateral foraminal approach that preserves facet integrity through a minimally invasive corridor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>The lateral foraminal approach begins with an incision along the lateral border of the sternocleidomastoid, proceeding obliquely \"outside-in\" through the interscalene space between the scalene muscles. Depending on the specific spinal level and corresponding orientation of the intervertebral foramen, this surgical concept incorporates both the anterolateral approach (C2\u20133 to C7\u2013T1) and the posterolateral approach (C1\u20132 and occasionally C2\u20133).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>The study comprised 30 males and 25 females with a median (range) age of 45 (11\u201369) years. The tumors were located from C1\u20132 to C7\u2013T1 intervertebral foramina. Gross-total resection with preserved facet joint integrity was achieved in all cases, with visualization safeguarding brachial plexus and VA integrity during resection. Surgery resulted in significant improvements in neurological function and pain, with mean Japanese Orthopaedic Association (JOA) scores increasing from 13.3 to 15.1 (p &lt; 0.001) and mean visual analog scale (VAS) scores decreasing from 4.3 to 2.4 (p &lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>The lateral foraminal approach is a minimally invasive technique for resecting cervical dumbbell tumors via an anatomical corridor.
