Objective:To analyze the three-dimensional radiographic characteristics of solid variant of odontogenic keratocyst(SOKC)using multi-slice spiral tomography(MSCT).Methods:Clinical records,histopathological reports and MSCT images of 8 patients were retrospectively acquired,radiographic features,including lesion site,size,borders,jaw expansion,internal structures and relationship with surrounding tissues were analyzed.Results:8 cases(4 males and 4 females)aged 37-65 years were included.Among them,4 lesions were located in the maxilla and the other 4 in mandible.Clinically,the lesions manifested as an enlargement of the affected area in the jaw bone,with pain present in 6 cases.On MSCT scans,all lesions showed evident jaw expansion.The boundaries of the lesions were clear in 3 cases,and unclear in 5 cases.4 cases exhibited multilocular radiolucent lesions,while the other 4 cases showed mixed radiolucent/opaque lesions resembling fibro-osseous lesion.The maxilla lesions involved the palate,na-sal cavity,maxillary sinus and orbital floor.All mandible SOKCs were recurrent and infectious,with involvement of the surrounding soft tissue.Conclusion:SOKC exhibits imaging characteristics that differentiate from conventional odontogenic keratocysts.Radio-graphically,it presents as a benign or low-grade malignant solid jaw mass.

OBJECTIVE: To investigate the clinical effects and life quality of 43 cases with carcinomas in maxillary sinus by sequent combination therapy. METHOD: All the patients were subjected sequent and combination therapy, which included inductive chemotherapy through superficial temporal artery, operation and radical radiation therapy, and of these, 18 patients were added consolidation chemotherapy after combination therapy. Three year survival rate, 5- year survival rate and life quality were observed in a 5 years follow up. RESULT: All patients completed this therapy, the overall 5-year survival rates were 46.5% (20/43) and 3-year were 65.1% (28/43). None were undertaken orbital exenteration and 12 patients recovered their ability of work and manual labour. CONCLUSION The sequent combination therapy is an effective method to enhance the prospective efficacy of treating the carcinoma of maxillary sinus and can raise the local controlling rate. The induced chemotherapy through the temporal artery superficial has many advantages, such as high density of topical remedy, obvious tumor regression after only a cycle chemotherapy, not delaying the surgery opportunity and so on. The consolidation chemotherapy after this combined therapy can reduce the risks of distant metastasis further.
