Laser pilonidal plasty is a type of laser treatment for a pilonidal cyst and sinuses. These cysts occur just above the tailbone and are pockets in which debris such as hair, skin, and fluids congregate and can become infected. The goal is to remove the cyst, its root if embedded, clear out the area, and use preventative measures in order to keep the cyst from reforming in the future.
Laser pilonidal plasty is a short minimally invasive procedure. Rather than excision of the cavity, the cavity is ablated with the laser. In general the procedure involves anesthetizing the affected area by your medical team. They will then proceed to remove the cyst and its pit if applicable, and clear out any remaining debris such as hair and other articles that congest the site. Once this is completed the area is flushed out and cleansed before the laser is applied. The laser utilizes intense light that is produced by an internal fiber and is controlled through a probe with a glass tip. The doctor will take the probe and insert it into the pilonidal sinus, holding the laser at such an angle so that the pilonidal opening is in line with the laser beam. This helps to keep any healthy tissue from being damaged in the process, closes the wound, destroys the tract lining and is repeated as necessary until complete.
