Microdebrider use in orbital surgery.

Purpose: To report the novel use of a sinus microdebrider for the removal of tissue during orbital surgery.

Methods: This retrospective study reviewed the logs of 3 surgeons to identify patients who required orbital surgery during which the surgeon chose to use a sinus microdebrider with an open sky technique as a means of removing portions of the orbital tissue. Collected data included patient demographics, clinical examinations, pathologic diagnoses, radiologic studies, operative reports and, when available, photographs and intra-operative video.

Results: Three patients were identified as having undergone orbital surgery assisted by the use of a sinus microdebrider. The first patient had an extensive, recurrent left orbital myxoid tumor. Debulking of this gelatinous, infiltrative mass was aided by the combined suction and cutting action of the microdebrider. Two cases involved orbital exenteration for infiltrative sino-orbital fungus infection resulting in a blind eye and frozen globe. Removal of orbital apical tissue during exenteration surgery was facilitated with the microdebrider.

Conclusions: The characteristics of the sinus microdebrider make it a useful adjunct for orbital surgery, particularly in situations where tissue may be difficult to grasp and excise. Caution should be exercised whenever using this electrically powered tool due to its potential for rapid tissue destruction. Therefore, the microdebrider should only be used in cases in which there is little risk of damage to essential orbital structures.
