The advantage of transconjunctival incisions is the superior cosmesis due to lack of a cutaneous scarring. A disadvantage maybe a limited access of non-extended or non-combined approaches in comparison to lower-eyelid skin incision.
2. Access areas
The typical (lower fornix) transconjunctival approach in the lower eyelid exposes the floor of the orbit and infraorbital rim as well as the upper edge of the anterior maxilla (A). Via a pre- or transcaruncular incision, the medial wall of the orbit behind the posterior lacrimal crest can be exposed (B). The combination of the lower fornix and the medial transconjunctival approach provides access to both previously mentioned areas at a time.
