Indents and crooked nose 7 months after rhinoplasty. Do I need a revision? (Photo)

Many thanks for your questions and for sharing your photographs.
During the healing process your nose will go through changes which may result in formation of some irregularities. It is paramount to wait for 12 months after a primary rhinoplasty surgery to assess the final result. I appreciate that you feel anxious and wish to avoid any further risks and cost implications associated with a revision surgery, but I am afraid you need to remain patient. Only then, you and your surgeon can fully assess the outcome and weight the benefits vs risks of revision surgery if indicated.
Wishing you all the best.

Hi and welcome to our forum!
From your photos, I note slight irregularity the the bridge at the bone / cartilage junction, the bridge is slightly high, and there is minimal displacement of the nasion from midline. However, the patient is only 7 months after surgery...
The procedure of rhinoplasty involves separation of the nasal bones and cartilages from overlying and underlying tissues, fracturing and reshaping of bone, trimming and reshaping of cartilage. The tissue trauma resulting from this "insult" is significant, resulting in the inflammation of healing, swelling (which may be asymmetric), firmness and a slight degree of warmth which may persist for a year or longer. This phenomenon will gradually subside. Some surgeons advocate the use of nasal tapes to control the swelling in the early postoperative period.
It is still too early to ascertain the result of your surgery. One must wait at least one year to determine the result. Swelling can masquerade as bone and cartilage displacement early on.
Continue follow up with your plastic surgeon. 15% of cosmetic surgeries benefit from a secondary touch up.
Best wishes...
