[Approach to the nasal dorsum in rhinoplasty : preservation or structural?].

In modern rhinoplasty, two foundational approaches for modifying the nasal dorsum developed in the beginning of the 20th century: -preservation and structural techniques. Preservation involves -maintaining the nasal structure by displacing the hump into the nose without directly resecting it. This method preserves structural integrity and avoids nasal valve collapse but can lead to mid-vault widening and hump recurrence. In contrast, structural rhinoplasty entails -directly removing bone and cartilage, offering precise hump reduction but risks over-resection, dorsal irregularities, and mid-vault collapse. The patient's individual anatomical factors guide the practitioner in choosing the most suitable -approach for correcting the nasal dorsum.
