The deep plane facelift has become a ubiquitous term in aesthetic surgery, yet Dr. Michael Byun, founder of Chicago Cosmetic Surgery, contends that the technique is often misunderstood. Rather than treating the face as a single sheet of tissue pulled toward the ears, Byun utilizes his proprietary BYUN Vector Technique to address the face as a three-dimensional structure. This method involves dissecting individual anatomical units and repositioning them according to their original biomechanical orientation.

Byun draws parallels between surgical precision and disciplines like architecture and aviation, suggesting that mastery of foundational anatomy is the prerequisite for innovation. By shifting the focus from lateral tightening to restoring support along original muscle vectors, the procedure aims to avoid the over-pulled appearance often associated with traditional methods. This philosophy centers on the belief that facial rejuvenation is not merely about operating beneath the SMAS, but about respecting the dynamic movement and individuality of the patient's face.
