Alar Preservation Principles: Alar Hinge Flaps.

Preservation rhinoplasty is a groundbreaking advancement increasingly embraced by surgeons worldwide, applicable to a diverse range of nasal anatomies, including the preservation of alar cartilages. Its growing popularity stems from the principle that preserving nasal structures, rather than removing and reconstructing them, results in a more natural appearance and fewer long-term complications. Alar preservation procedures, which focus on maintaining the integrity of alar cartilaginous structures and various nasal tip ligaments, have evolved through reevaluating and refining older techniques with insights from recent anatomic studies.
