Lower Eyelid Blepharoplasty

50

 

Amir M. Karam and Samuel M. Lam

 

 

 

50.1 Introduction

Aging of the lower periorbital region is a complex process involving both soft-tissue excess and volume loss. As a result, successful rejuvenation of this region requires a thorough understanding of the aging process and its influence on the complex anatomy. Lower eyelid blepharoplasty is the principle operation performed to rejuvenate the lower eyelid region.

It is considered a technically challenging operation with a myriad of variations and paradigms. The technical challenge of this procedure is due to the fact that a very fine line exists between an enhanced aesthetic outcome and significant functional and aesthetic complications.

Traditional blepharoplasty techniques have been criticized for their failure to truly restore a refreshed and youthful appearance. Often, following aggressive removal of skin, muscle, and fat, the infraorbital region is left looking hollowed, which actually has the opposite effect on the appearance. Modern periorbital rejuvenation paradigms involve a combination of treatment modalities, ranging from conservative blepharoplasty techniques, volume restoration, and skin resurfacing.

An intimate and thorough understanding of the anatomy coupled with an understanding of the natural history of lower eyelid aging is required to achieve a successful surgical outcome. In this chapter, we evaluate the periorbital aging process and how blepharoplasty can be used in addition to other treatments to restore the youthful structure of this area.

50.2 Periorbital Aging

The youthful lower eyelid should have a short lid– cheek junction and a smooth gentle convexity that blends into the upper cheek mound as a single convexity [1]. With age, a combination of fat volume loss overlying the inferior orbital rim, weakening of the orbital septum resulting in fat pseudoherniation, descent of the malar fat pad, sagging of the orbicularis oculi muscle resulting in lengthening of the lid–cheek junction, exposure of the bony outline of the inferior orbital rim occur. These factors combined results in a double-convexity contour deformity. The orbital fat is the superior convexity, directly below this is the relative concavity defined by arcus marginalis along the skeletonized inferior orbital rim, and the second convexity is defined by the cheek mound. This finding is a telltale sign of aging of the central face. Tear-trough deformity or nasojugal fold is described by a depression at the transition of the medial aspect of the lower eyelid and upper cheek. The resultant deformity causes the periorbital region to have fatigued and aged appearance. This finding is caused by a deficiency of tissue, not excess. Therefore, removing skin, muscle, or fat from the lower eyelid will worsen this deformity.
