A safe and accurate method of assessing the size of implants required in orbital floor reconstruction.

Many methods to determine the size of an orbital floor implant depend on trial and error. However, this technique is imprecise and the repeated insertion and removal of the implant leads to soft tissue trauma and swelling. A method of measuring orbital floor dimensions intraoperatively using a waterproof paper ruler is presented in this study. This technique has the advantage of being simple, precise, safe, and expedient.
