Is it safe to have a Rhinoplasty with only being off of phentermine (blood thinner) for 10 days?

Phentermine is an appetite suppressant, not a blood thinner. You should
discuss what medications, supplements, and vitamins you are taking, both
prescription and over the counter, with your plastic surgeon and have him or
her decide what you should and should not be taking. Your surgeon should be
certified by the American Board of Plastic Surgery and ideally a member of the
American Society for Aesthetic Plastic Surgery (ASAPS). It is important to
follow all pre and post-operative instructions.

 It is very important to get clearance from  your hematologist to be off blood thinners for 2 weeks before the surgery and 2 weeks after the surgery, to prevent a nose bleed situation. Your hematologist and your  rhinoplasty surgeon should have discussions about the best care moving forward undergoing elective cosmetic surgery
