Lateral canthal support should be considered a routine component of lower transcutaneous blepharoplasty to obtain the desired aesthetic result and maintain the natural appearance of the eyelid shape. The associated complication rate is acceptable.
The lower eyelid can be a challenging area in facial rejuvenation. While lower eyelid bags are commonly the reason that patients present for lower eyelid rejuvenation, a separate entity known as a tear trough deformity may occur in conjunction with lower eyelid bags or alone. In this article, the authors outline the current understanding of the tear trough anatomy; describe multiple classification systems, which provide an objective means of evaluating the deformity and aid the surgeon in choosing appropriate treatment options; and review surgical and nonsurgical techniques for correcting the tear trough deformity. Treatment options include hyaluronic acid filler, fat grafting, skeletal implants, and fat transposition. Each procedure is associated with advantages and disadvantages, and each should be considered more complex than traditional lower blepharoplasty alone. While lower blepharoplasty removes excess fat and may tighten the anterior lamella, tear trough procedures require the addition of volume to the underlying depression. These procedures requiring release of the ligamentous structures and orbicularis (of which the tear trough is composed), as well as fat transposition or fat grafting, are associated with additional complications, which are also reviewed.
The use of total reoperation rates as an indication of complications of breast implants can lead to both an overestimation of implant-related complications and the inaccurate conclusion that silicone implants result in higher complication rates than saline implants. The implant-specific reoperation rate may provide a more accurate incidence of implant complications than the total reoperation rate, which includes reoperations for factors unrelated to the implant.
The retaining ligaments of the face are important in understanding concepts of facial aging and rejuvenation. They are located in constant anatomic locations where they separate facial spaces and compartments. Their superficial extensions form subcutaneous septa that separate facial fat compartments. Their main significance relates to their surgical release in order to achieve the desired aesthetic outcome. Furthermore, they have a sentinel role in their anatomic relationship to facial nerve branches. When performing facial aesthetic surgery, plastic surgeons should select a plane of dissection, release the appropriate ligaments depending on the desired aesthetic goals, and avoid nerve injury by using the ligaments as anatomic landmarks. Descriptions of the retaining ligaments are variable in the literature; due to different interpretations of anatomy, several classifications, locations, and nomenclature systems have been proposed. This article will review and clarify the anatomy of the retaining ligaments of the face, including the cheek, mandible, temporal, and periorbital areas.
Evolution of silicone breast implant design has focused primarily on advances in implant fill, surface texture, and shape. Fifth-generation, shaped, form-stable, silicone breast implants from all three major implant manufacturers are now approved for use by the U.S. Food and Drug Administration in the United States. As part of this approval, the U.S. Food and Drug Administration mandated Core Study follow-up of silicone implants for 10 years after premarket approval. An updated and comprehensive collection of Core data from all three manufacturers is presented in this review. In addition, cause and rates of capsular contracture, seroma, rippling, and malposition are discussed. New concepts such as tissue friction coefficient are discussed that may influence outcome after primary breast augmentation. The theoretical advantages and disadvantages of the various textured surfaces ranging from microtexturing to macrotexturing are presented in relation to breast tissue incorporation.
Reconstruction of the eyelids after excision of skin cancer can be challenging. Knowledge of surgical eyelid anatomy and appropriate preoperative planning are critical in order to perform eyelid reconstruction and minimize complications and the need for reoperation. The fundamental principle for full-thickness eyelid reconstruction is based on reconstructing the subunits of the eyelid, including the anterior and posterior lamellae as well as the tarsoligamentous sling.
Enduragen has proved to be a very satisfactory substitute for ear cartilage and fascia in eyelid surgery in both reconstructive and primary eyelid cases. It seems to be far superior to other commercially available tissue substitutes because of its predictability of structure and robust behavior. All problems that were encountered in this series seemed to be related more to technical errors than to any deficiency in or reaction to the Enduragen. The increased strength, rigidity, and durability give support to the lids comparable to that obtained with autogenous ear cartilage and fascia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
