Dorello's canal
Dorello's Canal is the bow-shaped bony enclosure surrounding the abducens nerve and the inferior petrosal sinus as the two structures merge with the cavernous sinus. It is sometimes found at the tip of the temporal bone. The petrosphenoidal ligament or petroclinoidal ligament also known as Gruber ligament, forms the superior border of Dorello canal, the conduit for the abducens nerve.
This canal is named after the famous Italian anatomist Primo Dorello, who proved the existence of this canal after a series of meticulous dissections.
