The document discusses cryosurgery techniques for treating common warts. It recommends using a liquid nitrogen spray gun with the timed-spot freeze technique, freezing the wart for 10 seconds and treating in 2-3 sessions spaced 3-4 weeks apart. For plantar warts, it advises using the spray gun with a double freeze-thaw cycle to fully destroy the wart. Margin sizes of 2mm for common warts are sufficient.
