doi:10.13701/j.cnki.kqyxyj.2025.01.011

摘要/Abstract

摘要： 目的:应用锥形束CT(cone-beam computed tomography, CBCT)观察人群中上颌窦底解剖形态特征,为上颌窦底相关手术治疗提供临床参考。方法:收集在海南口腔医院放射科就诊的300例患者CBCT影像资料,利用CBCT自带软件测量工具对患者上颌窦底及邻近相关解剖结构进行观察、测量及统计学分析。结果:上颌窦底黏膜平均厚度(1.26±1.06) mm,黏膜厚度<2 mm者占87.00％(261/300)。窦底骨分隔发生率为33.67％,其中男52例,女49例,男性和女性比较无差异(P＞0.05)。窦底形态为浅凹型者占54.33％(163/300)、深凹型占39.33％(118/300),凸起型占6.33％(19/300)。上颌窦外侧壁平均骨厚度为(1.34±0.26) mm,骨厚度主要集中在1.0~1.5 mm,占60.67％(182/300)。上颌窦外侧壁动脉血管走形主要方式为窦内型、骨内型,分别占37.33%(112/300)、52.00%(156/300)。结论:上颌窦底解剖形态个体化差异较大,利用CBCT 影像学能够全面客观地反映,因此在涉及上颌窦底相关手术前应仔细研究分析,规避可能存在的手术风险,并依此制定详细的治疗方案。

Abstract: Objective: To observe the anatomical and morphological characteristics of maxillary sinus floor in the population by cone-beam computed tomography (CBCT). Methods: CBCT data of 300 patients who visited the Radiology Department of Hainan Stomatological Hospital were collected, and the patients' maxillary sinus floor was observed and measured by software. Results: The average thickness of the mucosa on the floor of the maxillary sinus was (1.26±1.06) mm, basically centered on <2 mm, which accounted for 87.00% (261/300). The incidence of septum of maxillary sinus floor was 33.67%, of which 52 were males and 49 were females, there was no difference between males and females (P>0.05). Shallow concave sinus floor accounted for 54.33% (163/300), deep concave was 39.33% (118/300), and convex was 6.33% (19/300). The average bone thickness of maxillary sinus lateral wall was (1.34±0.26) mm, mainly concentrated between 1.0-1.5 mm, accounting for 60.67% (182/300). The main location of arterial vessel of the lateral wall were sinus type and intraosseous type, accounting for 37.33% (112/300) and 52.00% (156/300), respectively. Conclusion: The anatomical morphology of the maxillary sinus floor is highly individualized and can be comprehensively and objectively reflected by CBCT. It should be carefully studied and analyzed before surgery so as to avoid possible risks and formulate detailed treatment plan.
