Dressings after skin cancer reconstruction are usually not needed. One exception is if you have a skin graft performed. This will usually have to be kept covered with a dressing and kept dry for 5 days. If there are any other gauze dressings, these are removed the day after surgery. Once the dressing comes off, there is no need for any further dressing. Antibiotic ointment should be applied twice a day to all the incisions once the dressing comes off.
Rarely, for extremely large reconstructions your surgeon will use small drains that stay in for 1-2 days only. These help drain the fluid that is produced under your skin as part of the healing process. Without drains, this fluid can accumulate, termed a seroma. The drains are easy to take care of, and do not hurt to take out.
