Yes, it is definitely safe to do water sports a year after a rhinoplasty procedure. In fact, most patients can go back to pretty strenuous activities within the first month of having the procedure done. Certainly a year is more than long enough to allow for adequate healing and any sort of injury that could theoretically occur would not only injure an otherwise normal unoperated nose, but could theoretically also injure a nose that has undergone a previous rhinoplasty. Typically after 2 weeks, the nasal bones are relatively well healed and certainly after 1 month they are very well healed and are very unlikely to be displaced due to some unexpected trauma. That is why I typically allow my patients to return to overall normal activity including water sports within a month after the rhinoplasty procedure.
