Traditionally, professional medical and surgical society meetings, journals, and texts are single-specialty driven to accommodate specific specialists with information most important to them. A consequence of this structure is that it can create an unintentional and artificial barrier to sharing knowledge that can benefit patient outcomes. Cosmetic and reconstructive surgeons, more than ever, are seeking to know what other specialists are doing. This publication, the first of a series, focuses on the brow and upper eyelid rejuvenation and presents varied and complementary techniques from the core specialties of Plastic surgery, Oculoplastic surgery, Facial plastic surgery, and Dermatology to address all aspects of rejuvenation procedures of the upper face. Surgical and non-invasive techniques are presented concisely, focusing on time-tested as well as novel procedures. The most talented and accomplished subspecialists in their respective fields provide insights into such topics as Preoperative Evaluation for the Upper Eyelid and Brow; Aesthetic Enhancements in Upper Blepharoplasty; Asian Upper Lid Blepharoplasty; Prevention and Intraoperative Management of Blepharoplasty Complications; Ptosis Repair in Aesthetic Blepharoplasty; Adjunctive Fat Grafting of the Brow/Upper Lid; The Open Brow Lift; Adjunctive Skin Care of the Brow and Upper Lid; among many others. Specific techniques, Patient perspective and goals, and clear anatomic descriptions are presented with each procedure, with several offering technique videos. Guest editors Babak Azizzadeh and Guy Massry strongly believe that, with more and varied practitioners with different training taking on cosmetic and reconstructive surgeries or procedures, transparency of information is essential in order to expose the best information to all practitioners of this art and science.
