Sinusitis 2 years after rhinoplasty?

2 years ago I had a rhinoplasty from turkey. I didn’t realise but at the time of surgery I also had a staph infection. I was using a nose hair trimmer & would get pus filled pimples inside the nostrils each time I used it. After surgery I noticed they became more frequent. So I went to an ENT he did an MRI & X-ray and said I had mild sinusitis & it can be caused by the surgery.Is this true?Also my nose hair seems less in my nose after the surgery, i keep getting dust particles inside
