Teaching of the lateral tarsal strip technique using a duct tape simulation

Published:August 02, 2021DOI:
      A lateral tarsal strip is a surgical procedure commonly used in oculoplastics for the repair of entropion and ectropion. A lateral tarsal strip involves correction of horizontal lid laxity with incision at the lateral canthus. Residents may have difficulties with suture placement of the tarsal strip in the periosteum. In an effort to facilitate the surgical teaching of this technique, we propose a straightforward surgical simulation to reproduce the technique. A plastic skull model, standard duct tape, surgical instruments, and suture are needed. In our experience, this is a reasonable reproduction of the periosteum of the lateral orbital wall (Figure 1) .

Generally, a small semicircular needle is used for the lateral tarsal strip procedure. For demonstration purposes, a larger 3/8-inch needle was used. A small ball in the orbit may be added to better simulate the spatial restrictions for needle placement.
