Not sure what you guys are doing with the suture, etc...
By their nature, verruca won't affect cells below epidermis / basement membrane.
For a sharp excision on verruca, you just need to go with small margin around the clusters (15 blade), can be circle or a bit elliptical.
Then use a sharp curette to scoop it out and get to the (white) basement membrane... curette it. Send one or two to path.
Be a bit lighter on WB areas heel or MPJs... but still try to get down to basement membrane.
Do cautery, silvadene, bandage... bandage, surg shoe, heals by secondary intention over next 2-3wks.
See them around 12d and 21d or so (10d global). Avoid ointments as these need to dry out usually (alc clean, silv cream sites or just betadine rim of excis sites).
Tell them pre-op that it sometimes it leaves a scar (usually it won't if you get technique down).
Do this in OR... sedation, lido w epi below and prox to lesion clusters. Better lights and instruments.
Office is way too messy, inject is very painful, time consuming. Don't be waste time or hurt ppl. That's TFP stuff. 🙂
Code is 1142x family (as many times as you do clusters).... 10d global.
If you do verruca with proper debride + 30-50% sal acid crm (w or w/o 5FU in it), maybe canth... you'll barely need to do any in OR. The debride of callus is more important than the % sal.
90% will resolve in office with sal acid and PROPER DEBRIDE. 95% with canth (I offer it if no progress with a few sal tx). You can try cimetidine PO. Have them use home pumice + sal at home (sell little jars of it as OTC product).
The very few that don't resolve were usually real bad and/or there for years before they came to you. It happens. Board them for OR if they want, keep trying sal if they don't want to do OR.
The sharp excision is rarely needed, but the recur should be very very low... usually minor and at another area (virus is in their body, obviously).
