To evaluate and compare the clinical results of marsupialization and curettage in the treatment of jaw cystoid disease, and application of the denture type cyst plug.

Eighty-one patients with jaw cystoid disease were treated with marsupialization (36 cases) or curettage (45 cases) . The correlation of the two groups was compared, and the postoperative complications and recurrence were compared. Data was statistically analyzed using SPSS 13.0. Data was listed as ±s. Operation time, blood loss, retention affected teeth, numbness of the lower lip, treatment effect and recurrence rate of two treatments were analyzed using the χ² test.

Operation time for patients treated with marsupialization was (31.2 ± 4.1) min, the amount of bleeding during operation was (20.3 ± 7.2) ml, affected teeth extraction was (0.7 ± 0.04) , postoperative pain, numbness of lower lip, infection, and masticatory function decline index were significantly lower than the curettage group 3 years after surgery. The difference was statistically significant (P<0.05) . Three years after surgery the curettage group was found slight asymmetry of facial shape in 6 cases and 2 recurrence cases (4.4%) . No surface shape change and recurrence was seen in the marsupialization group. There was no significant difference in the recurrence rate of the two groups (P>0.05) .

Comparing with curettage, marsupialization is a simple, practical and effective method with less damage, complications. and keep the jaw and teeth in the affected area intact.
