The transconjunctival approach to the orbital floor and orbital fat. A prospective study.
The transconjunctival approach to the inferior orbit and orbital fat offers the potential advantage of avoidance of scar creation in the lower eyelid skin and anterior lamellae. Complications of this approach, including conjunctival fornix shortening and eyelid margin malposition, have been occasionally reported. We prospectively observed 25 patients undergoing transconjunctival blepharoplasty and orbital floor surgery. Fornix depth, eyelid margin position, and the presence or absence of eyelid retraction were measured preoperatively and at each postoperative visit. No significant permanent change in these parameters was observed. Temporary entropion was observed in two patients; this resolved with conservative treatment. On self-limited suture granuloma was observed. In a subgroup of six patients, the conjunctival incision was closed on one side and left unclosed on the other. No adverse healing was noted on the unclosed side. We conclude that the transconjunctival approach is associated with a low incidence of complications, and that it does not significantly alter the fornix depth or eyelid margin position. A skin incision is avoided. The inferior orbital septum is not violated, greatly reducing the risk of development of lower eyelid retraction.
