What activities in rhinoplasty are needed to get similar results? (Photo)

Thank you for your questions and for sharing your photograph.
You have a wider lower 2/3 section of your nose, particularly the middle section. Rhinoplasty can improve this for you.
Rhinoplasty can improve the aesthetic appearance of your nose and reduce the bulbosity of your nasal tip.
Rhinoplasty is one of the most delicate and complex cosmetic surgeries, given the intricate structure of the nose and the balance it provides to a face.

It is a common misconception to think that the nose can be sculpted as if it was a piece of marble or that one can choose a “perfect” celebrity nose from a magazine.

There are limitations based on the individual's intricate nasal anatomy and nasal skin quality. For example, a thick nasal skin is great in covering up minor irregularities but since it does not shrink well after surgery, it will not show fine underlying refinements to the same extent as those with thin skin.
I would suggest that you consult with an expert rhinoplasty surgeon and discuss what you do and do not like about your nose.
The use of manipulated (morphed) digital clinical photography provides a platform for discussion as to your desires and expectations. Such images are not a guarantee of exact results, but a great tool to ensure that you and your surgeon are on the same wavelength.
Best wishes

A closed rhinoplasty approach can accomplish improvement and refinement of your nasal tip, however thick-skin cannot be changed and will be a limitation as to how much refinement you can obtain in the nasal tip itself. When patients have thick skin, they also require multiple steroid shots in the first several months after the surgery to reduce excess swelling present. The dorsal hump can also be shaved down, and the bridge line narrowed with all the incisions placed on the inside of the nose. No external incisions are required, no painful packing is required either. Digital computer imaging on your nose upon your facial features would be helpful to understand what can and cannot be accomplished
