Abstract
|
|
|
|
Radiofrequency (RF) devices deliver high frequency energy to the biological tissues thath as been either cut or coagulated. A pulsed-type RF irradiation elicits thermal and/or non-thermal effects by delivering a particular rate of gated RF oscillations. In the present study, we describe two patients with nasal rosacea, who were effectively treated with invasive pulsed-type, bipolar alternating current (AC) RF treatment using microneedle electrodes. The RF treatment was delivered to these two patients with a power level of 3, a microneedle penetration depth of 1.5 mm, and 2?3 passes over six (patient 1) and 12 (patient 2) sessions, at two-week intervals. The first patient presented marked clinical improvement with respect to both the overall redness and papulopustular lesions; the second patient exhibited noticeable improvement in both the texture and telangiectatic lesions on the nose. Both patients were satisfied with the clinical outcomes without remarkable side effects.
