Nose was Broken 9 Months After a Septoplasty, Can it be Repaired?

A broken nose can be repaired following prior septoplasty. If your main issue is that your nose is now crooked, deviated or twisted then yes the nasal bones can be straightened. If your injury was in the past couple of weeks then the bones can be straightened without making any incisions. If the injury is older than that then the nasal bones might need to be straightened surgically. In either case, these are very common procedures for an experienced Facial Plastic Surgeon or Plastic Surgeon to perform.

Reduction of a nasal fracture and realignment of the nasal bones can certainly be done whether or not a septoplasty has been performed in the past.  It is also important to make sure the septum has not been fractured with the new injury.  Otherwise, that deviated septum will need to be addressed as well.  An experienced rhinoplasty surgeon will have no trouble straightening the inside and outside portion of the nose through closed rhinoplasty techniques.

You can certainly have repair of a nasal fracture after a septoplasty. The indications for repair of the nasal fracture would included a visual deviation of the nose.

 Yes, but a Septoplasty removes areas of the nasal septum that are deviated and bent.  Once removed, these can't contribute to airway obstruction related to additional nasal trauma.  Your nose should be examined by an experienced Rhinoplasty Surgeon for further recommendations.
