Happy Fourth of July Weekend! To celebrate, we thought we would put together a little red, white, and blue for YOU!
As many of you know by now, cysts come in all shapes, sizes, and colors! I thought on this holiday weekend, I would explain to you why the following cysts are Red, White, & Blue!
Red: This is a cyst excision on the left cheek, and I think it's pretty obvious why there is a little red here. After all, this is a surgical excision!
White: Local anesthetic used contains lidocaine, sodium bicarbonate, and epinephrine. The NaHCO3 (sodium bicarb) is used to buffer the lidocaine, raise the pH so that it burns less when it is injected. Epinephrine is added because this constricts local blood vessels which helps to minimize bleeding, and also increases the time of anesthesia, keeping lidocaine in the area for longer. Cysts are most commonly white in color, containing macerated keratin (wet skin cells).
Blue: This cyst I was pretty pleased to remove intact. In general, this is what I try to do.. it keeps the area cleaner and neater, and also assures me more that we have removed the entire cyst and it's wall completely. This cyst had a white fibrous membrane around it and the cyst was more grey in color, so it had a slight bluish hue as it was removed.
Happy Red White & Blue Day! Have a great holiday weekend! And happy Canada day, too!!
Thank you for watching!
