Conservative Treatment of Unicystic Ameloblastoma

Background: Treatment of unicystic ameloblastoma should be conservative as possible, to avoid serious complications
resulting from radical surgery. The aim of this study was to evaluate the effect of enucleation with bone curettage followed by
application of carnoy's solution in conservative treatment of unicystic ameloblastoma.
Materials and Methods: This study included 10 patients seeking treatment for unicystic ameloblastoma, which were
confirmed by: preoperative CBCT that showed unilocular radiolucency, and histopathological examination of incisional biopsy
specimens. Final enucleation specimens were used for additional confirmation and for unicystic ameloblastoma subtyping.
Unicystic ameloblastoma was treated by enucleation with bone curettage followed by application of carnoy's solution.
Results: This study involved five males and five females, with an age ranged from 12 to 70 years, and an
average age 32.8 years. All the lesions occurred in the mandible; eight lesions in posterior mandible and two lesions in anterior
mandible. Four lesions were associated with impacted teeth. Root resorption occurred in six cases. Considering histopathological
subtypes; three cases were luminal, one case was intraluminar, and six cases were mural. No recurrences were observed in all
cases, after 30 months.
Conclusion: Unicystic ameloblastoma even mural types can be successfully treated conservatively by enucleation with bone
curettage followed by application of carnoy's solution.
