[Use of tomodensitometry in the pathology of the orbit]

A standardised method with an original reference line in C.A.T. exploration of the orbital region permits to visualize the entire orbital region with four tomographic scannings when using 6 mm tomographic sections. Some exemples of orbital lesions are demonstrated as optic nerve tumor, dysthyroïd exopthalmos, maxillary sinus tumor with extension into the orbit.
