On this page:
Gross anatomy
Dorello canal is an interdural space (between the two layers of dura) found at the medial most end of the petrous ridge at the confluence of the inferior petrosal, basal, and cavernous sinuses 6.
Boundaries
superiorly: petrosphenoidal ligament (Gruber ligament)
inferiorly: petrosal process of the sphenoid bone
medial: dorsum sellae
lateral: petrous apex 6
History and etymology
Named after Primo Dorello (1872-1963), the Italian anatomist who described the anatomical relationship of structures within the canal in 1905 3.
