The Importance of Orbital Curvatures
The orbital floor and wall curvatures define the position of the orbit in terms of both functionality and aesthetics. The implant reconstructing these curvatures must therefore have the correct curvatures to provide a satisfactory repair. We present below what we see on a regular basis: a patient whose ineffective orbital repair needed revision with a customised implant to achieve the correct result.
This CT scan reconstruction shows the shape of the primary repair: it is cylindrical as opposed to achieving the anterior-posterior S-shape raising and supporting the eye ball higher up in the orbit.
It was a difficult task to remove the original repair (left). It was then replaced by the customised repair (right) which will 1) hold its shape while being inserted, 2) be inserted through a minimally invasive incision, and 3) achieve the correct contour to restore the correct anatomical position of the eye ball.
The location of the incision to insert the customised implant is usually just above or just under the eye lash line. The implant is then securely attached to the orbital rim. Please note that the incision is usually smaller than shown on this photo (here necessary to gain access to and extract the original repair).
