Of course, the collapse of the nose bridge is a risk of this operation. If all goes well, more than 98% of patients will not appear. Not shallow, not long. Because the nasal septum is just a baffle between the nostrils on both sides, and the right or wrong of the nose is because the nasal bone is at work.
But now that you know the doctor-patient relationship, you should sign an agreement before surgery to inform the patient of all possible risks. If there is a so-called small probability event, you can only bear it yourself under normal circumstances.
Good luck ~
