Pilonidal cysts can now be treated with a super-thin laser - with a fiber optic diameter of 400 microns (less than half a millimeter), which makes the beam diameter just one thousandth of a millimeter. This method allows for complete healing of all fistulas and dermoids, without excision of the inflammatory structure. There is no longer a need for massive tissue removal – which means no large wounds or fissures. After an ultrasound examination of the Pilonidal cyst, it is sealed off with a laser beam; the abscess is opened by two tiny laser incisions and removed. After removal, the laser beam is focused on the closed cavity, and in this way the previously disinfected inflammatory cavity is drawn together and reduced. The area in which the fistula was removed is automatically disinfected and sterilized with the laser beam. A minor post-surgical treatment of the external tissue must be performed. The minimal invasive laser procedure, allows for complete healing within two to three weeks.
