Extirpation of cysts occurring in soft tissue is generally associated with rupture of the cystic wall, making complete removal difficult. Especially in cases of a plunging ranula, where the cyst often lacks an epithelial wall, complete extirpation is frequently not feasible. Furthermore, the wall of a lateral cervical cyst has been reported to have ruptured during surgery because the cyst was fused with the internal jugular vein.<BR>We thus injected agar hydrocolloid impression material into the cystic cavity, which facilitated complete removal of the cyst.<BR>We treated two cases utilizing this method, an 8-year-old female (Case 1) with a large plunging ranula and a 20-year-old male (Case 2) with a lateral cervical cyst. Approximately 1 year 8 months and 1 year 3 months postoperatively, recurrence has not occurred in cases 1 and 2, respectively. We concluded that this method is effective for extirpation of cysts arising in soft tissue.
