Ultrasonic Aspiration for Debulking Infiltrative Masses of the Orbit

PURPOSE To demonstrate the utility of an ultrasonic aspirator (Sonopet, Stryker Corporation; Kalamazoo, MI) for debulking firm, soft tissue masses of the orbit. METHODS Case series. The ultrasonic aspirator was used to debulk firm, soft tissue masses in 3 cases. The initial patient had a large orbitofacial mass extending to the inferior and lateral orbital apex secondary to IgG4 disease. The second patient had a lacrimal sac adenocarcinoma extending to the medial orbital apex. The third patient had a large orbital mass extending to the apex secondary to granulomatosis with polyangiitis. RESULTS The ultrasonic aspirator facilitated debulking of infiltrative firm soft tissue masses of the orbit. The device's ability to emulsify, irrigate, and aspirate, along with its small footprint, facilitated precise sculpting and debulking to an extent which would have been difficult otherwise due to location. CONCLUSIONS The ultrasonic aspirator allows precise sculpting of infiltrative firm soft tissue masses in the orbit and is particularly useful in cases with challenging anatomical access.
