Can a deviated septum or a nasal collapse be caused through a rhinoplasty operation?

Possible: I understand you are concerned of possible failure of rhinoplasty. As with any surgical interventions, a chance of failure is not 0. I cannot comment on specific types of failure not knowing the details, but again all surgeries carry some risk of not being successful.

Dr Tholen and another doctor agreed

Possibly: There are specific techniques which must be followed in order to perform rhinoplasty and minimize the risks of septal deviation or nasal collapse. These complications are always possible, but they are unlikely in skilled hands.

Yes: Yes, a rhinoplasty can cause a deviated nasal septum or nasal collapse. Yet, in the hands of an experienced rhinoplasty surgeon these complications are extremely rare, if not unheard of!

Dr Ali and another doctor agreed

Nasal collapse: Septal deviation and nasal valve collapse unfortunately can be iatrogenic (caused by prior surgery) in nature. That is why it is so important to choose your primary surgeon carefully to minimize this risk.

Dr Baez agreed

Deviated septum: A deviated septum can be corrected in the context of rhinoplasty. Deviation of the septum is not often a sequela of rhinoplasty but overresection of cartilage can lead to nasal valve collapse.

Dr Juchau agreed
