目的 研究上颌窦骨质破坏的临床意义。方法 回顾 72例上颌窦骨质破坏病例 ,对照病理结果 ,利用统计学分析骨质破坏的意义。结果 47.2 2 % ( 34/ 72 )的骨质破坏出现于良性上颌窦病变中 ;5 2 .78% ( 38/ 72 )的骨质破坏出现于恶性上颌窦病变中 ;两者的差别无统计学意义 (u =0 .3335 ,Ρ >0 .0 5 )。大多数的膨胀性骨质破坏 ( 84.85 % ,2 8/ 33)出现于良性上颌窦病变 ;大多数的侵蚀性骨质破坏 ( 84.6 2 % ,33/ 39)出现于恶性上颌窦病变中 ;良、恶性上颌窦病变的骨质破坏的类型不同 ( χ2 =34.6 1,Ρ <0 .0 5 )。 31.5 8% ( 12 / 38)的恶性上颌窦骨质破坏及 5 .88% ( 2 / 34)的良性上颌窦骨质破坏区中可见“碎骨片” ,“碎骨片”征多见于恶性上颌窦病变(u =2 .5 7,Ρ <0 .0 5 )。结论 上颌窦良、恶性病变均可有骨质破坏 ;对骨质破坏类型及其征象的进一步分析 ,可以鉴别良、恶性。
Objective To study the clinical significance of maxillary sinus bone destruction. Methods A retrospective study of 72 cases of maxillary sinus bone destruction cases, the control pathological results, the use of statistical analysis of the significance of bone destruction. Results 47.2 2% (34/72) of the bone destruction occurred in benign maxillary sinus lesions; 52.78% (38 of 72) of the bone destruction occurred in malignant maxillary sinus lesions; the difference between the two was not statistically significant Significance (u = 0 .3335, Ρ> 0 .0 5). Most of the expansive bone destruction (84.85%, 28/33) occurred in benign maxillary sinus lesions; most of the erosion of bone destruction (84.62%, 33/39) occurred in malignant maxillary sinus lesions; good , And the types of bone destruction in malignant maxillary sinus lesions were different (χ2 = 34.61, P <0.05). 31.5 8% (12/38) of malignant maxillary sinus bone destruction and 5 .88% (2/34) of benign maxillary sinus bone destruction area can be seen in the “broken bone piece”, “broken bone piece” sign more common in malignant Maxillary sinus lesions (u = 2.57, P <0.05). Conclusion The benign and malignant maxillary sinus lesions may have bone destruction; further analysis of the type of bone destruction and its signs, can identify benign and malignant.
