Can lower lateral cartilage be avulsed?

Thank you for your question about nose surgery.Yes, nasal cartilage damage or separation is possible.To be sure, see two or more experienced, board-certified Plastic Surgeons or  ENT surgeons for a complete evaluation to make sure you are a good candidate and that it is safe for you to have surgery.I hope this helps.

Yes. This is certainly possible. The scroll area where the upper and lower lateral cartilages come together could have been injured. Valve collapse can usually be effectively treated with a variety of techniques including alar batten grafts and spreader grafts, among others.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Yes it is certainly possible that you have separated the lower lateral cartilage from the upper lateral cartilage.  A thourough exam by a Plastic Surgeon or Facial Plastic Surgeon with an ENT background would be your best bet for advice and possible correction. 

Anything is possible with severe nasal trauma, we have never seen an avulsion of the lower lateral cartilage in over 25 years. Valve collapse can be either internal or external when it occurs. Treatment can range from a spreader graft, batten graft or  alar rim graft, but that decision is  made at the time of consultation and examination.
