目的:探讨下颌骨髁突骨软骨瘤的诊治经验,恢复髁突正常的解剖形态和生理功能。方法:对1998—2008年收治的14例下颌骨髁突骨软骨瘤患者的诊治进行评价,指标包括影像学检查确诊率(X线、3D-CT及MRI)、开口度、咬合关系及术区感觉。根据检查指标进行临床诊断及手术效果评价。结果:X线、3D-CT和MRI的确诊率分别为57.1%、66.7%和87.5%。3D-CT和MRI检查能更清晰地反映肿物情况,为手术提供良好的指导。14例患者均行手术治疗,术后效果良好。结论:MRI和3D-CT检查是诊断下颌骨髁突骨软骨瘤的最佳方法,能较好地观察肿物的范围及位置关系,为手术提供良好的依据,而X线检查在下颌骨髁突骨软骨瘤的诊断中具有重要价值。
Objective: To investigate the diagnosis and treatment of mandibular condylar osteochondroma and to restore the normal anatomy and physiology of condyles. Methods: The diagnosis and treatment of 14 cases of mandibular condylar osteochondroma treated during 1998-2008 were evaluated. The indexes included the diagnostic rate (X-ray, 3D-CT and MRI), the degree of opening, the occlusion relationship and the operative area feel. According to the test indicators for clinical diagnosis and surgical evaluation. Results: The diagnostic rates of X-ray, 3D-CT and MRI were 57.1%, 66.7% and 87.5% respectively. 3D-CT and MRI can more clearly reflect the tumor situation, provide a good guide for surgery. All the 14 patients underwent surgical treatment and the effect was good. Conclusion: MRI and 3D-CT are the best methods to diagnose mandibular condylar osteochondroma, which can be used to observe the extent and location of the tumor and provide a good basis for surgery. X-ray examination in the mandibular condyle Osteochondroma diagnosis is of great value.
