[Comparative study of treatment of keratocysts by enucleation, enucleation combined with cryotherapy or fixation of the cyst membrane with Carnoy's solution followed by enucleation: a preliminary report].

Comparative study of treatment of keratocysts by enucleation, enucleation combined with cryotherapy or treatment with Carnoy's solution followed by enucleation: a preliminary report. The aim of this preliminary report was to compare the effect on the recurrence rate of keratocysts treated by enucleation (group E, 14 cysts), enucleation combined with cryotherapy (group EK, 14 cysts) or a fixing agent (Carnoy's solution) followed by enucleation (group CE, 10 cysts). A total of 32 patients with 38 keratocysts are included in the study. In group E 5 recurrences (36%) was developed after 17, 34, 36, 37 and 39 months postoperatively, whereas 5 recurrences (36%) after 22, 24, 24, 25 and 59 months was registered in group EK. Due to a rather high incidence of side effects to cryotherapy this treatment technique can not be recommended. No recurrences has been found in group CE, and usually complete bone healing has occurred after 6 to 12 months postoperatively. Due to the use of the strong fixing agent we recommend treatment by this method performed under general anaesthesia to secure an immobile surgical field. In accordance with recent studies, the results indicate that fixation before enucleation has revolutionized the art of treating keratocysts with respect to recurrence rate.
