What could be the cause of the shape change to my columella a month after my phone fell on my nose and can it be fixed? (Photo)

In general, trauma to the nose, even after a previous surgery, can potentially cause changes in its shape or structure. The impact from your phone falling on your nose could have caused damage to the underlying cartilage or tissue, leading to the visible line you mentioned. This could be related to changes in the alignment or position of the columella, which is the central part of the nose that separates the nostrils.

A revision procedure may be an option to address the changes and improve the appearance of your nose.

An « in person » consultation with a board certified plastic surgeon expert in rhinoplasty is of course, necessary.

I hope this helps,
best of luck !
