Access to the orbital cavity is gained primarily through an anterior approach (transconjunctival or transpalpebral approaches yield good cosmetic results) or through a lateral approach. The lateral Krönlein approach provides better intraoperative exposure. Transantral, transfrontal, transcranial, and trans-nasal orbitotomies are used less frequently.
Orbital exenteration is indicated with advanced malignant tumors. Thisinvolves removal of the entire contents of the orbital cavity including the eye-lids.
