Drawbacks and Limitations of Thread Rhinoplasty.

Abstract

Nonsurgical rhinoplasty using barbed threads has gained popularity in Asia as a result of being viewed as a minimally invasive procedure that is relatively inexpensive with a short recovery period and minimal complications. Usually, absorbable polydioxanone thread is used, but nonabsorbable thread is also sometimes used. When inserted, multiple barbs along the threads hook into the tissue, causing traction or stretching. Although minor tip projection or dorsal lengthening can be obtained simply using this procedure, it is difficult to increase volume sufficiently; therefore, the procedure is often combined with filler injection or fat grafting. However, the long-term benefit is questionable, since the filler is absorbed and fat is also partially absorbed over time.
