Transconjunctival approach revisited and anatomical considerations

The transconjunctival approach, first described by Bourqet in 1923, has become a routine procedure for the management of fractures of the orbital floor, medial and lateral walls, and infraorbital rim. It is also used in aesthetic surgery and access surgery. Different approaches of transconjunctival surgery, however, can be complicated by the complex lower lid anatomy. In this publication we revisit the anatomy of the transconjunctival approach, and discuss the surgical steps for preseptal and postseptal dissection. We introduce the concept of interseptal space (potential space), its anatomy first described in 1991.
