ABSTRACT
Orbital tumours pose numerous challenges in terms of diagnosis, imaging and management. They can be classified into three main groups according to their origin: primary lesions, which originate from the orbit itself; secondary lesions, which extend into the orbit from neighbouring structures and metastatic tumours. If the bones of the orbit are involved with malignancy, bone resection should be performed at the time of initial orbitotomy, even if that procedure is not an exenteration. An essential part of the decision-making process is reconstruction and rehabilitation of the exenterated orbital socket. If the entire eyelid anatomy is to be preserved, the operation is similar to an extended enucleation in which the eye with the bulbar conjunctival lining and the other orbital tissues are removed en bloc. In eyelid-sparing exenteration, one may need to spare either the entire eyelid structure or just the eyelid skin.
