The transconjunctival approach a minimally invasive approach to various kinds of retrobulbar tumors.
OBJECTIVE
Orbital tumors, particularly those within the retrobulbar space, were approached by maxillofacial, ophthalmic, and neurological surgeons. Less traumatic approaches in this functionally and cosmetically important region are desirable. We describe another method to remove orbital tumor in the retrobulbar space by a transconjunctival approach with lateral canthotomy and transient extraocular muscle severing without lateral orbitotomy.


METHODS
We report 5 retrobulbar tumors operated with a transconjunctival approach, 2 of which were intraconal. Contrast-enhanced computed tomography and magnetic resonance imaging scans were used to determine precise location of the retrobulbar tumor.


RESULTS
Retrobulbar tumors could be removed successfully through a transconjunctival approach. Three pleomorphic adenomas, 1 carvenous hemangioma, and 1 pseudotumor were the pathologic findings encountered. These patients were free from visible scars, proptosis, and any other noticeable complications at last follow-up, 6 months after surgery.


CONCLUSIONS
The transconjunctival approach, which involves lateral canthotomy and transient extraocular muscle severing without lateral orbitotomy, is an unconventional procedure for retrobulbar tumor and results in a successful outcome. The indications for this approach depend on the size, location, and nature of the tumor. In this regard, contrast-enhanced computed tomography and magnetic resonance imaging scans give useful information for planning operative strategy.
