Rhinoplasty splints and dressings are typically removed around one week post-op. It's much easier to remove at day 7 as compared to day 5 when the nose has more swelling. The integrity of the dressing is important after having a dorsal hump removed: your nasal bones need to remain imobilized for a week to prevent shifting. Dr. Joseph
Personally, I have my patients keep their cast on for 1 week. On the day of removal, I instruct them to soak their face in the shower. This helps loosen the cast which then peels off easily. The cast is used to keep everything in its place after surgery. Once the cast is off, it is very important to protect the nose. The most common injuries that I see during this important healing time is getting accidentally hit by a dog or child. Be careful especially careful around them! Good luck
