Does Pushing/pinching/pressing Nose into Certain Direction Can Change Shape?

You can't alter your nose's shape by merely pressing on it or pinching or pushing it. Think about the amount of pressure it takes to change the position of teeth: orthodontists have to apply a tremendous amount of consistent pressure with braces over a period of years to effect a permanent change. And even the option of a nose “brace” would not actually create a new nose shape: The cartilage that gives the nose its length and much of its shape is resilient and has “memory”: It returns to its original shape over time. If you want to change your nose shape, rhinoplastic surgery is the only way to do it. I hope this helps.

The nose is made of bone and cartilage (hard, firm structures) covered by skin. Compression of these structures will only compress the skin, but not the bone or cartilage. However, post-surgery, we often recommend compression exercises (see my website) to mold the fractured bones and to diminish soft tissue swelling. These exercises only work for about 6 weeks, while the patient is healing.

The human tissues do "adapt" its shape to changes in force however this cannot be applicable to the nasal framework. The nasal bones and too strong to be changed by forced while the cartilages are flexible and have a memory. Pushing on your nose does not change the shape of it permanently. The only thing that does is a surgical rhinoplasty procedure.
Hope this helps,
