Y. Ullmann et al., THE SURGICAL ANATOMY OF THE FAT IN THE UPPER EYELID MEDIAL COMPARTMENT, Plastic and reconstructive surgery, 99(3), 1997, pp. 658-661
The surgical anatomy of the upper eyelid fat in the medial compartment
was investigated in 388 patients and in 12 cadavers. We found two ind
ividual fat pads comprising this compartment. The difference among the
investigated cases was found to be the extent of their separation. In
16.7 percent of the cadavers' eyelids the fat pads were entirely sepa
rated, in 45.8 percent they were separated to about half their length,
while in 37.5 percent only the tips were separated. Among the patient
s in whom only the protruded fat was inspected, 59.8 percent of the fa
t pads were separated, and in the rest, only the tips were isolated. O
n histologic examination we could always identify two well-circumscrib
ed fat pads, each surrounded by a fibrocollagenous tissue. At the leve
l of their interconnection, a loose fibroareolar tissue was found. In
practice, during blepharoplasty, both fat pads should be addressed in
order to achieve the expected results.
