[Transconjunctival surgical cryoextraction of introconal orbital cavernous hemangiomas].

OBJECTIVE

To evaluate the Methods , complication and operative skill in transconjunctival surgical cryoextraction of intraconal orbital cavernous hemangioma.

METHODS

Among the 41 patients diagnosed as orbital cavernous hemangioma preoperatively, 36 suitable for the condition were treated with the operation. The operation time was recorded, and the complications were observed during and after the operation.

RESULTS

The tumours of the 36 patients were all excised successfully, of which 35 were diagnosed as orbital cavernous hemangioma, and the other 1 as neurilemoma post-operatively. The operation time of each was 20 to approximately 25 min and there was no perpetual complications.

CONCLUSION

Transconjunctival surgical cryoextraction of intraconal orbital cavernous hemangioma is simple, swift, safe and effective with tiny injury.
