目的探讨CT在诊断和鉴别诊断鼻及鼻窦肿瘤中起到的作用。方法以我院2013年6月~2016年6月期间收治的60例鼻及鼻窦肿瘤患者为此次研究对象,对患者鼻腔行CT检查,并按照检查结果将患者分为恶性肿瘤组和良性肿瘤组。恶性肿瘤组15例患者,良性肿瘤组45例患者。观察比较两组患者的肿瘤形态、密度、窦壁骨质破坏、周围脂肪层侵犯情况和窦腔外软组织肿块等情况。结果在本次研究中,恶性肿瘤组的窦腔外的软组织肿块、窦壁骨质侵犯性破坏、肿瘤对窦腔周围脂肪层的侵犯消失情况都明显高于良性肿瘤组,两组比较存在明显差异,有统计学意义。但两组患者的软组织肿块形态不规则、密度不均匀情况对比无统计学意义。结论 CT诊断能够对鼻及鼻窦肿瘤的病变范围进行有效观察,且可以鉴别恶性肿瘤和良性肿瘤,能够用于临床的鼻及鼻窦肿瘤诊断检查中。
Objective To investigate the role of CT in the diagnosis and differential diagnosis of nasal and sinus tumors. Methods Sixty patients with nasal and sinus tumors admitted to our hospital from June 2013 to June 2016 were selected as the study subjects. The patients underwent nasal CT examination and the patients were divided into malignant tumor group and benign tumor group group. 15 patients in the malignant tumor group and 45 patients in the benign tumor group. The morphology, density, bone destruction of the sinus wall, invasion of the surrounding fat layer and soft tissue mass outside the sinus cavity were observed and compared between the two groups. Results In this study, malignant tumor group of extracavitary soft tissue mass, sinus wall invasion of bone destruction, the tumor of the alveolar fat layer around the disappearance of infiltration were significantly higher than the benign tumor group, there was significant difference between the two groups The difference was statistically significant. However, the two groups of patients with soft tissue mass irregular shape, uneven density contrast was not statistically significant. Conclusion CT diagnosis of nasal and sinus tumors can effectively observe the extent of the disease, and can identify malignant tumors and benign tumors, can be used in clinical diagnosis of nasal and sinus tumors.
