State of the art: The Unilateral Cleft lip and Nose Deformity and Anatomic Subunit Approximation.

The anatomic subunit approximation approach to unilateral cleft lip repair was developed over 20 years ago. While the underlying principles of the repair are unchanged, its description has been simplified, additional landmarks and creases have been added, and objective analysis of perioperative changes have provided better clarity regarding goals and desired alterations. We review recent insights regarding the deformity; describe the repair in a simplified manner; and link a stepwise approach to foundation-based primary rhinoplasty as a part of the avenue to creating nasolabial balance and harmony.
