However, traditional exposures may involve extensive condylar drilling and muscle dissection, which can compromise craniocervical junction stability. This study aimed to define and quantitatively evaluate a stability-preserving mini far-lateral corridor that provides adequate surgical exposure while minimizing bony and soft-tissue disruption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>A systematic literature review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines to characterize technical advancements of the far-lateral approach. Additional cadaveric dissections were performed on 6 fresh-frozen adult specimens using a Z-shaped incision, single-plane craniocaudal muscle dissection, limited suboccipital craniectomy, and one-third occipital condyle drilling. Neuronavigation-based morphometric measurements were used to quantify petroclival exposure. A comparative statistical analysis was conducted against the classical (Spektor, 2000) and minimally invasive (Zhang, 2011) series.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      The mean petroclival exposure area was 376.86 \u00b1 45.54 mm\n                      <jats:sup>2<\/jats:sup>\n                      , larger than the values reported by Spektor et al (338.00 \u00b1 86.00 mm\n                      <jats:sup>2<\/jats:sup>\n                      ; t(17) = 7.22;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 1.49 \u00d7 10\n                      <jats:sup>\u22126<\/jats:sup>\n                      ) and Zhang et al (208.50 \u00b1 28.40 mm\n                      <jats:sup>2<\/jats:sup>\n                      ; t(16) = 20.31;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 7.61 \u00d7 10\n                      <jats:sup>\u221213<\/jats:sup>\n                      ).
