Dorello's canal
Dorello's Canal
Dorello's Canal (pronunciation: doh-REL-ohs kuh-NAL) is a small, anatomical passage located in the human skull. It is named after Italian anatomist Carlo Giacomini Dorello, who first described it in detail.
Etymology
The term "Dorello's Canal" is derived from the name of its discoverer, Carlo Giacomini Dorello. Dorello was an Italian anatomist who made significant contributions to the field of neuroanatomy in the late 19th and early 20th centuries.
Anatomy
Dorello's Canal is a small channel located at the base of the skull, specifically in the petrous part of the temporal bone. It is bounded by the petroclival ligament and the Gruber's ligament. The canal houses the abducens nerve, which is responsible for controlling the movement of a specific muscle of the eye, the lateral rectus muscle.
Clinical Significance
Due to its location and the important nerve it houses, Dorello's Canal is of significant clinical interest. Damage or compression of the abducens nerve within the canal can lead to abducens nerve palsy, a condition characterized by impaired eye movement. This can occur due to various reasons, including tumors, aneurysms, infections, or trauma.
