Abstract:
Objective:To analyze the there-dimensional radiographic characteristics of odontogenic myxoma(OM).Methods:Clinical records,histopathological reports,SCT or CBCT images of 18 patients with OM were retrospectively collected,and radiograph-ic features including lesion site,shape,size,expansion,intralesional septa and relationship with surrounding tissues were analyzed.The lesions were classified into types by the forms of septa.Results:18 patients(8 males and 10 females,aged 9-39 years old)were included.Among them,12 lesions(66.7％)were round-like in shape,7(38.9％)were located in the posterior maxilla,and 8(44.4％)in the posterior mandible.According to the septa map,the lesions included 4(22.2％)without septum(unilocular type),4 with(22.2％)sporadic septum on the periphery of the tumor(peripheral type),4(22.2％)with the septum from the periphery towards the center of the tumor(centripetal type)and 6(16.7％)with multiple septa interwoven as grid-like trabeclations(criss-crossing tup).Labial/buccal cortex expansion was present in 11 lesions(61.1％),and palatal cortex expansion in 12 lesions(66.7％).Moreover,cortex discontinuity occurred in 14 lesions(77.8％),impacted tooth was present in 9 lesions(16.7％),and root resorption was present in 8 lesions(44.4％).Conclusion:Most OMs occur in the posterior jaw,with multilocular and discontinued cortex.OMs can be classified into unilocular,perpheral,centripetal and cirss-crossing type by the forms of septa in the lesion.
