Abstract
Purpose: :
our purpose was to ascertain whether the magnetic resonance imaging (MRI), with the use of a surface coil, can accurately show the orbicular septum and related spaces, and its relationship with surface anatomy of the upper eyelid, and the position of the skin crease.
Methods: :
An oculoplastic examination and MRI of the orbit using a surface coil, was performed in 6 normal volunteers. We analysed the aspect of the upper eyelid and the position of the crease, compared with the position of the orbital septum, the upper lid levator, and the orbital fat pad.
Results: :
In hollow and normal eyelid (with little masked skin crease), the orbital septum insertion was high on the levator aponeurosis, and the orbital fat pad did not droop onto the septum. Whereas in the eyelid with masked skin crease, the septum insertion was low and the orbital fat pad drooped onto the septum, giving "the fullness" in the upper eyelid. There was redundant skin that formed the skin fold.
Conclusions: :
The high resolution MRI was able to analyse the architecture of the upper eyelid and its relationship with the surface anatomy: the fold formation of the lid, and the position of the skin crease.
