Correction of Ptosis Palpebral
What is it?
It is the surgical procedure used to lift the eyelids when they are fallen and obstruct vision or give the appearance of chronic fatigue and sleep. Regular access to the correction of ptosis of the upper lid is usually above or transcutaneous access. This offers the advantage of being able to correct excess skin and orbicularis muscle at the same time. It also allows a fuller account of the septum, orbital fat and the medial and lateral extent of the fascia. Why then need a transconjunctival or after the aponeurosis access when we can correct all the previous access? Subsequent access has the advantage of being more direct cause less trauma and to facilitate adjustment. It is especially useful when we have to correct the skin or orbicularis muscle as in cases that have already had a blepharoplasty or cases without altering the anterior lamella
And as is done
Depending on the degree of eyelid drop surgery is decided whether internally or externally without scar is made through the skin. Surgery is performed in about one hour.
PTOSIS, PALPEBRAL GROOVE AND SUPERIOR BLEPHAROPLASTY
A minimal and inadvertent ptosis only a millimeter can cause a rather asymmetric outcome after blepharoplasty. With blepharoplasty uncover the sulcus. The groove is located where the tarsal surface forms an angle with the surface preseptal. The position of this angle depends on the first eyelid open position relative to the eyeball (eyelid margin distance-corneal reflex), the second position of the eyebrow (eyebrow-groove distance) and third tissue such as skin, muscle and fat completing this angle (Fig. 8.2). Tissue resection is performed as blepharoplasty exposes the groove angle. A minimal ptosis therefore not notice the small distance between the corneal center and the eyelid margin, but much more by rising groove (increased distance between the eyelid margin and groove). In many cases a small ipsilateral ptosis also induces a brow lift which multiplies the elevation of the groove. There are cases where a small ptosis millimeter groove causes an elevation of five millimeters. In these cases selectively correcting the causative factor, ptosis. As access provides the most direct route, transconjuntival.
