I agree with Dr. Pelosi. It is not the "instrument; it's the hand holding the instrument! Experience, experience, experience..! But, I will be more specific regarding "wavy lines." "Wavy lines," which distort an otherwise handsome result, occur only with so-called "trim," aka "linear" labiaplasties. The truly elegant labiaplasties, maintaining "individuality" and producing lovely "flow" from hood to the vaginal opening most always come from "wedge" procedures. Personally, I have won several "Best Of" awards at International meetings: all have come with Wedge modifications. Yes, ~ 50% of my ~ 900 labiaplasties are performed by "trim." Trims are easy to perform, and if done properly can give fine (but uniform, "straight up & down") results, but they are also easy to mess up. Wedges are masters-level procedures; you won't find many beginners utilizing wedge techniques. (Want to find the BEST surgeon? Look for someone who performs both wedges and linear, so that they can choose the best technique for you personally, rather than the only one they're proficient at.) One of the way trims (trim is same as linear...) can be messed up is a wavy incision line, either because the surgeon wasn't careful enough cutting, or they used the wrong closure technique. Personally, I prefer a long-jawed Keye or Metzenbaum or curved Iris scissors for a single straight incision line (can also do with a cold cutting fine wire RF or laser touch fiber.) For closure, the most important is to either use fine monofiliment 2-layer sub-cutaneous and sub-cuticular suture line; if using through & through sutures they must either be rapidly dissolving (like Vicryl Rapide or plain catgut, not tied too tight or, if using longer-duration sutures, removing skin sutures in ~ 10-14 days. But again, skill & experience counts. Look for a surgeon who can PROVE to you that (s)he has taken a bone fide training course and has 10+ before and after photos on their site, or if no formal training can show you at least 30+ good-outcome photos. If the photos aren't there, this surgeon does not have the experience (unless they took a good course, like mine, Red Alinsod's, Marco Pelosi's, Alex Bader's, Dawid Serafin's. Amr Selfaldin's, etc.) Best wishes! Michael P Goodman, MD, FACOG, IF, AAACS. Davis, CA, USA
