The Clinical Research Of The Marsupialization For Unicystic Ameloblastoma

Ameloblastoma were the most common odontogenic tumor inmaxillofacial tumors. Although the benign tumor, it growsinvasive, and has the characteristics of local infiltrationbone, with a high recurrence. So the marginal of surgicalresection should be outside the tumor within0.5-1.0cm abovethe normal bone tissue, avoiding the residual of tumor cellsand lead the recurrence. Unicystic ameloblastoma patients ofaverage age is only26years old, at the lesion area isrelatively large, if treated by radical surgery, patients hada greater influence on the function and aesthetics.Marsupialization in the treatment of cyst has achieved goodeffect, also avoid the influence of jaw defects and beautiful.If we treat the Unicystic ameloblastoma patients bymarsupialization firstly. If the marsupialization waseffective in reducing the size of the lesion, it was followedby enucleation and curettage. Then you may keep the patient’sjaw, can maximum limit to avoid the influence is beautiful, andreduce the burden of the patients. Aimed at the problem, this study discusses the fenestrationtype single cystic ameloblastoma curative effect, the analysissummarizes the matters needing attention in the process offenestration for fenestration in the treatment of type singlecystic ameloblastoma aspects to provide clinical basis. aretrospective analysis15UM patients treated between2009-2012in Maxillofacial Surgery of Stomatology MedicalCollege of Jilin University. Summarize the data such as gender、age、lesion location、follow-up period、Radiographic featuresand recurrence. Collect the radiographic data ofpre-operation、 post-operation (3months、6months、12months).Compare the lesion area of pre-operation withpost-operation, matching t test between pre-operation withpost-operation (3months), then discuss the effect ofmarsupialization. All the patients were diagnosed unicysticameloblastoma. There is no difference in distribution withregard to sex, but age is a factor, with adults (mean age,25.9years) affected more often and children only rarely. They occuronly in the mandible, especially the molars, the mandibularangle, and the ramus.in our research. The follow-up period inour research is2.27years, and the recurrence is7%. All thepatients is treated by marsupialization,12patients have a great change of the lesion in5-17months, large number of newbone formation arrouding, the best one reduce80.13%.theminimum is22.23%,matching t test between pre-operation andpost-operation (3months),P＜0.01， the difference wasstatistically significant.2patients have no change aftermarsupialization, enucleation is followed, we found onepatient had a good effect after marsupialization, the capsulechanged into fibrous structure, although the radiograph showedno changes. The effect rate of marsupialization is13/15(86.68%).For the UM, firstly treated by decompression, when thelumen decreased significantly, large number of new boneformation arrouding, the enucleation is followed. Thus can keepthe jaw from curettage, maximize the preservation of patientsand reduce complications, reduce the burden on patients, butpatients need close follow-up, timely detection and treatmentlocal recurrence.
