Background: The transconjunctival approach paired with lateral canthotomy is a commonly used technique for widened exposure of the orbital floor and infraorbital rim. A major drawback of this approach is the severance of lateral canthal ligament fibers, which predisposes to potential postoperative eyelid malpositioning. To avoid these suboptimal aesthetic outcomes, a modification of this approach has been proposed in which the lower eyelid is mobilized with a paracanthal, trans-tarsal stair-step incision. In this pilot study, we describe our experience with the trans-tarsal stairstep incision for lateral extension of the transconjunctival incision and report its outcomes in a Western population.
Methods: All patients who underwent facial fracture operative fixation at a single institution by a single senior surgeon were included. Clinical variables were extracted. Patients were stratified by incision type.
Results: Compared with patients who underwent subtarsal incision (n = 20) and transconjunctival incision with lateral canthotomy (n = 4), patients who received the trans-tarsal stair-step incision (n = 10) had no incision-related complications or requirements for revision. The most common complications found in the comparison groups were ectropion and hypertrophic or irregular scarring, and 4 patients required revision.
Conclusions: Our initial experience with the transconjunctival approach with the trans-tarsal stair-step incision shows promising outcomes. Further study may promote greater utilization of this technique in Western countries.
