transconjunctival approach
Pronunciation: trans-kon-JUNK-tih-val
Surgical access technique through the lower eyelid conjunctiva to reach the orbital floor and rim.
Full Definition
The transconjunctival approach involves making an incision through the conjunctiva of the lower eyelid to access the orbital floor, inferior orbital rim, and medial orbital wall without creating external skin incisions. This technique can be performed with or without lateral canthotomy and offers excellent visualization while minimizing visible scarring and reducing the risk of eyelid malposition compared to subciliary approaches. The approach may be combined with a lateral canthotomy for enhanced exposure. Pre-septal and post-septal variations exist, with the post-septal approach providing more direct access to bony structures while the pre-septal approach offers better protection of orbital contents.
Usage
Usage note: Specify whether pre-septal or post-septal approach is used for clarity.
