The Anterior Commissure Revisited

Abstract
Reexamination of the anterior commissure from the perspective of semantics, the anatomy of tumor spread, and connective tissue histology and embryology has reaffirmed previously published findings. In addition, this investigation of the convergence of the various structures toward the anterior commissure has led to the hypothesis that the anterior subglottic larynx may have a midline embryological origin. Whether this area should be included in the “anterior commissure” or possibly better considered as an area to which anterior commissure tumors spread is as yet undetermined.
