First of all: nasal septum deviation surgery is painless! I just feel uncomfortable within 24 hours after operation, because the whole nasal cavity is filled with a lot of gauze and I can't breathe through my nose.

In addition: the operation of nasal septum is done by otolaryngologists.

And rhinoplasty is done by plastic surgeons.

This idea of yours is very good. But in China, it's hard to find an otolaryngologist in any hospital who can also do rhinoplasty.
