To the Editor.

—Despite the fact that cystic tumors account for a large number of orbital lesions,¹ classic texts contain comparatively little information concerning the technical aspects of their removal.² In general, sharp dissection under magnification and adequate illumination is used to separate the cyst wall from the surrounding orbital tissue. Removal of these lesions requires a fine balance between traction on the tumor itself, either with atraumatic forceps or a cryoprobe, and countertraction on the surrounding orbital tissue. This traction/countertraction develops a plane of dissection that is aided by the intralesional pressure that defines the cyst wall.

In areas of dense adherence to surrounding tissue, dissection can lead to inadvertent rupture of the cyst. The loss of the intralesional pressure causes collapse of the cyst, making further identification of the cyst wall, and dissection, sometimes difficult.

Putterman and Goldberg³ have described the use of a cryoprobe . . . [Full Text PDF of this Article]
