  • Title: Novel strategy for orbital tumor resection: surgical "displacement" into the maxillary cavity.

    Abstract:
    Surgical intervention consisting of lateral orbitotomy, the indication of which is extremely wide for orbital tumor surgery, has been applied in cases of large, retrobulbar cavernous hemangioma. However, no method exists involving displacement of the tumor from the crowded orbital contents, with the exception of tumor traction toward the outer side. The impact of traction force on the fragile hemangioma is extremely traumatic and dangerous. The authors examined how a tumor might be "displaced" in the absence of traction force effect, into an appropriate cavity neighboring the orbit. The maxillary sinus may afford the most suitable space to shift the laterally situated orbital tumor. Thus, the osteotomy level was extended to the lateral half of the inferior orbital floor and orbital rim in order to displace the tumor through an "escape window" of sufficient size between the orbit and maxilla. This report describes the treatment of two cases with long histories of progressive proptosis associated with retrobulbar large cavernous hemangiomas. This novel procedure resulted in a successful outcome. The current approach and management, which involves displacement of the tumor into the maxillary sinus through the orbital floor escape window, is a novel procedure for orbital tumor surgery.
