Background and Objectives
Rhinoplasty with cosmetic filler is becoming an exceedingly popular, nonsurgical, cosmetic procedure, especially among Asians. However, the slim and pointed appearance achieved initially after treatment with filler injection tends to diminish over time, provoking complaints of a blunt shape and an overall enlarged nose due to flattening of the injected filler. This report describes the use of polydioxanone (PDO) threads and hyaluronic acid filler to correct a flattened, widen nose in two Korean women.
Materials and Methods
Two patients who had previously undergone treatment with filler injections presented with widened noses. Therein, we injected 150 IU of hyaluronidase to dissolve remnant hyaluronic acid filler, and after 3 weeks, we inserted PDO threads and hyaluronic acid filler via non-surgical rhinoplasty.
Results
In both patients, hyaluronidase dissolved previous filler that had begun to disintegrate and lead to a widened nose. Subsequent treatment with PDO threads and hyaluronic acid filler restored the desired appearance of a slim and pointed nose. No adverse side-effects from either treatment were reported.
Conclusion
The use of hyaluronidase and non-surgical rhinoplasty with PDO threads and hyaluronic acid filler are useful in the correction of a widened nose created by repeated injections of hyaluronic acid filler.
