Do you need to wear a cast for a tip rhinoplasty?

Hi and thanks for your question.
In rhinoplasty thermoplastic cast is used for stability of the nasal bone. During the rhinoplasty, osteotomy is done for 2 aim;
After removing the nasal hump , open roof is created on the nose, so this open roof is closed with osteotomy( cutting the nasal bone with ultrasonic device)If the bony base of the nose is too wide , it is decreased with osteotomy.
If during the rhinoplasty, osteotomy is done , thermoplastic cast is used for stability of the nasal bone and this cast is removed 7-10 days after the surgery. If rhinoplasty contains only tip plasty, cast may not be used ,because there is no need for nasal bone stability.

There are a wide variety of alterations to the tip that range from the simple to complex.  As far as splinting is concerned the surgeon will probably tape the tip to keep swelling down and possibly a splint as well for a period of time.  Every surgeon has their own routine.  Your surgeon can tell you what you can expect and your time for resuming activity.
