I'm a military pilot. Will I be ok to wear an oxygen mask post Rhinoplasty and Chin Implant? (photo)

I would definitely avoids oxygen mask pressure for up to two months after the procedure. On top of that you may have some stuffiness of you nose and pressure equilibration may be difficult, causing ear disease.

Flight mask after nose and chin surgery? If the mask does not cause pressure on the nose or chin it is ok. If the bones are not broken it is ok. It takes 6 weeks for the nose to set firmly but I have to u;se a chisel after 2 weeks to rebreak the nose. I was a flight surgeon in the Air Force but the make may have changed since then.

The rhinoplasty procedure usually involves osteotomies to the nasal bones which can leave the nose tender to pressure for the first month or 2 after the procedure. The chin is also tender from placement of the implant for the first month or 2 as well. It should be acceptable to put your mask on, but you may have some mild pain and pressure when the mask is applied tightly.
