Reduction of lower palpebral bulge by plicating attenuated orbital septa: a technical modification in cosmetic blepharoplasty.

Bulging of the lower eyelid is regarded as a sign of aging. "Herniation" of the periorbital fat pads is traditionally regarded as the factor responsible for the change. Excision of fat pads, therefore, has been the mainstay of treatment in reducing the palpebral bulge in cosmetic blepharoplasty. The surgical excision of"excess" and "herniated" fat pads, however, causes problems such as lid ecchymosis, chemosis, lid contour irregularity, ectropion, and retrobulbar hematoma formation. The author proposes that the loss of fat pad support caused by the attenuation of the orbital septa, not herniation of the excess fat pads, is the major factor responsible for the bulge. The author further proposes that the functional integrity of the orbital septum can be restored by plicating the attenuated orbital septa with 5-0 absorbable sutures. This technique of invaginating the protruded fat pad was performed in 138 individuals (276 lower eyelids). The operation was technically simple, and the approach was "tissue friendly." The results obtained, with the exception of a mild degree of puffiness encountered soon after the surgery, were satisfactory. Morbidity was minimal.
