[Technique and Results for the Transconjunctival Removal of Orbital Haemangiomas]

Abstract

Background: The cavernous haemangioma (cavernoma) is the most common orbital tumour in adults. Various surgical approaches have been described so far. We prefer a transconjunctival approach and analyse herein how our outcomes compare with those of transcutaneous or transosseous approaches.

Methods: A retrospective series of 10 cases was analysed with regard to surgical success and complications.

Results: The tumour could be completely removed in all cases. In one case, preoperative diplopia disappeared after surgery. Another case suffered from postoperative diplopia, which resolved within two months. Two cases developed a long-lasting partial tonic pupil.

Conclusion: A retrobulbar cavernoma can be safely removed via a transconjunctival approach through shrinkage by coagulation and subsequent cryoextraction.
