Levator lengthening by marginal myotomy
A. S. Grove Jr
A surgical procedure has been designed for lengthening the levator
aponeurosis by two partial-width (marginal) myotomy incisions. This
operation does not require complete division or disinsertion of the
levator, Muller's muscle, or tarsus. No foreign materials or sclera need to
be inserted into the lid. The procedure has been used to treat upper lid
retraction due to ophthalmic Graves' disease and for eyelid reconstruction
after resection of basal cell carcinoma that involves the lid margin. Since
an anterior incision is made through the skin, adhesions between the
levator aponeurosis and the overlying tissues may be divided in patients
with Graves' disease.
