Middle-vault Collapse and Detached Lateral Cartilage Due To Trauma, What Can I Do To Fix This?

It is very hard to detach upper lateral cartilages from bone.  That mechanism for middle vault collapse is still given yet is incorrect.

When the bridge is lowered for any reason (dorsal resection, hump removal, septal trauma), the upper laterals sink toward the midline, producing the collapse that you see. In your case the septum has been  damaged, which has also shortened your nose.

The reverse also works: a significant dorsal graft will pull the upper laterals out, open your airway (doubling your airflow, a shown by my research in 600 patients like you), and correct the contour problem.

 

See an experienced surgeon whom you trust--these techniques sound easy but require skill.

 The nose does appear different in the two pictures after the nasal trauma and IMHO, you should have a few consultations with experienced Rhinoplasty surgeons to examine and evaluste your nose for corrective Rhinoplasty and possible Septoplasty.
