Do you mean a nasal canulla during surgery, or splints after surgery?Looking forward to your comments to orient better this answer.Thanks.
A urinary catheter is not part of a rhinoplasty.However, in recovery room very few patients cannot void as a result of the anesthetics and narcotics used. A catheter may be interested to drain a full bladder Then its removed and the patient may be cleared for discharge . This is more common people who have known bladder problems or men with enlarged prostates.
