“No-Touch” Technique for Lip Enhancement
The authors stated in the last paragraph of the introduction that the “standard infiltration technique” can lead to prolonged edema and asymmetry. I would like to know what the standard infiltration technique refers to. Does it include a technique other than the no-touch technique, or other methods such as acellular dermal matrix, silicone implants, or dermal grafts? I would also like to know how frequently edema or asymmetry occurs in the standard infiltration technique. Among the 410 patients who were treated using the no-touch technique, how many suffered from edema or asymmetry?
The authors analyzed 410 patients’ anthropometric measurements, found five components to an attractive smile, and divided the lips into three areas. Did the treatment depend on the analysis of the records (Figs. 4 and 5) of each patient? If so, how did the analysis of each patient influence his or her individual treatment?
Finally, in Figure 15, a small gap is present in the occlusal plane in the preoperative photograph, and the patient is gritting her teeth in the postoperative photograph. I would be grateful if the authors would provide me with the preoperative and postoperative photographs to improve the gummy smile while retaining the same occlusion and tension.
