Can a plastic surgeon do a sinus surgery along with a rhinoplasty?

I am not sure if you really need sinus surgery or just septoplasty surgery.   General plastic surgeons often perform septoplasties but sinus surgery is just done by someone board certified in ENT/Otolaryngology. If you truly need sinus surgery and rhinoplasty please consult someone experienced on both and board certified in Facial Plastic Surgery and ENT. I wrote one of the first book chapters in how to perform both at the same time and have been doing this for 25 years.

Yes, it is indeed possible and even advisable to have
both a sinus surgery and rhinoplasty done at the same time should both
procedures be necessary. If they are done simultaneously, you will only have to
be placed under anesthesia a single time and will only have to go through
downtime/recovery once.
