Cryosurgical management of myxoid cysts.

Eighteen patients with digital mucoid cysts and 31 with myxoid cysts of the oral mucosa were treated by cryosurgery using an intermittent spray technique. Double freeze-thaw cycle (FTC) is recommended for successful treatment of digital mucoid cysts, as the recurrence rate was fairly high when only a single FTC was used. This does not necessarily apply to oral mucous cysts, where the cure rate was nearly 100%, whether a single or double FTC was used. We conclude that liquid-nitrogen-spray cryosurgery is an effective alternative in treating mucous cysts.
