Taping the Nose After Asian Rhinoplasty - How to Do It?

In general taping helps to efface the nasal skin envelope back down on the underlying nasal framework.  Start at the top of the bridge and work your way down with overlapping pieces of tape until you reach the tip.  Your surgeon may instruct you otherwise if there is a specific issue he/she is trying to address.  

Your tip will continue to drop through the healing process, as the edema (swelling) resolves.  Especially for Asian skin, this can be a lengthy process.  Typically taping is performed from the top down.  If your surgeon asks you to do something you don't understand you should always feel comfortable asking him/her to explain.   

Swelling can make the nose appear more upturned than it actually is. Tape can also be used to diminish swelling by controlling edema. This may be the intent of your surgeon.

It sounds like you are right--no taping an upturned nose further up. If you are too upturned you will need grafting to derotate the tip and lengthen the nose.

It does not sound logical to tape a nose "up" after rhinoplasty if you want to lengthen the nose. I doubt taping will change tip position 4 weeks after surgery. However, I cannot second guess your surgeon - - ask the physician you trusted to refine your nose.
