目的探讨CT提示的各种骨质改变对上颌窦良恶性病变的鉴别诊断价值。方法回顾性分析经病理证实的上颌窦良恶性病变101例的CT表现,观察、统计各种骨质改变的部位、范围和类型。结果良恶性病变引起骨质破坏出现率分别为57.5%(23/40)和85.2%(52/61),73.9%(17/23)的良性病变引起的骨质破坏呈单发,而恶性病变引起的骨质破坏以多发为主(78.8%,41/52),两组比较均有显著性差异(P<0.01)。骨膨胀改建的发生率良性组40.0%(16/40),恶性组13.1%(8/61)(P<0.01)。骨质硬化良性组37.5%(15/40),恶性组14.8(9/61)(P<0.01)。突破窦壁外侵的发生率良性组5.0%(2/40),恶性组36.1%(22/61)(P<0.01)。上颌窦内侧壁和鼻甲骨质破坏的发生率良恶性组无显著性差异(P>0.05)。其它骨壁的骨质破坏恶性组均多于良性组。结论分析CT所示骨质改变的不同部位、范围和类型,在上颌窦良恶性病变的鉴别诊断中具有重要的价值。
Objective To investigate the differential diagnosis of benign and malignant lesions of maxillary sinus with various bone changes indicated by CT. Methods The CT findings of 101 cases with pathologically confirmed benign and malignant maxillary sinus were retrospectively analyzed. The location, range and type of various bone changes were observed and counted. Results The incidence of bone destruction caused by benign and malignant lesions were 57.5% (23/40) and 85.2% (52/61), respectively. The bone lesions caused by benign lesions in 73.9% (17/23) The main cause of multiple bone destruction (78.8%, 41/52), the two groups were significantly different (P <0.01). The incidence of bone expansion reconstruction was 40.0% (16/40) in benign group and 13.1% (8/61) in malignant group (P <0.01). Bone sclerosis benign group 37.5% (15/40), malignant group 14.8 (9/61) (P <0.01). Breaking the incidence of sinus invasion was 5.0% (2/40) in benign group and 36.1% (22/61) in malignant group (P <0.01). There was no significant difference in the incidence of maxillary sinus medial wall and nasal bone destruction between benign and malignant groups (P> 0.05). Other bone destruction of bone malignant group were more than benign group. Conclusion The analysis of different parts, ranges and types of bone changes in CT shows great value in the differential diagnosis of benign and malignant maxillary lesions.
