If you have a depression, a dent, in your profile, it is probably the result of trauma to your nose. If you hit your nose and suddenly develop a new bump in your nose, it may be that the lower 1/3 of your nose has become a bit depressed. Often an injury to the nasal septum can depress the lower 1/3 of your nose below the bones, giving the impression of a bump above the area of trauma. Trauma to your nose as a child could also be the cause, often a fall that you do not even recall. Injury to the microscopic growth centers in the nasal bones or the septum can cause the nose to grow crooked or develop a depression called a “saddle deformity”. Correction usually involves an open rhinoplasty approach to the nasal septum to raise it and/or a cartilage graft to the nasal profile (dorsum) to fill the defect.
