：探讨ＣＴ扫描对上颌窦骨间隔畸形的诊断价值。方法：对８例经ＣＴ扫描确诊、手术证实的上颌窦骨间隔畸形患者的临床资料进行分析。结果：８例中，垂直冠状分隔者５例，水平分隔者２例，垂直矢状分隔者１例。双侧者３例，单侧者５例。上颌窦窦内骨间隔所分成的腔隙有交通者４例，无交通者４例。根据ＣＴ扫描检查，患者分别接受了经上颌窦筛窦根治术和面正中揭翻进路行上颌窦、筛窦、蝶窦联合根治术。术后患者均痊愈出院，随访半年无复发。结论：表明复发性鼻息肉和慢性鼻窦炎患者，术前ＣＴ扫描检查可有效地发现残余病变的范围和手术区的解剖异常，对术前手术设计，特别是对功能性鼻窦内窥镜手术具有重要的指导作用。上颌窦骨间隔术前的确诊主要依赖于高分辨率ＣＴ的轴位和冠位两个断面的扫描检查。
To investigate the value of CT scan in the diagnosis of maxillary sinus osseous deformity. Methods: The clinical data of 8 patients with confirmed maxillary sinus bone deformity confirmed by CT scan and surgery were analyzed. Results: Of the 8 cases, 5 were vertical coronaries, 2 were horizontal dividers, and 1 was vertical sagittal dividers. Bilateral in 3 cases, unilateral in 5 cases. Maxillary sinus sinus space divided into lacuna 4 cases of traffickers, no traffic in 4 cases. According to CT scan examination, the patients underwent maxillary sinus ethmoidectomy and median facial dissection into the maxillary sinus, ethmoid sinus and sphenoid sinus radical mastectomy respectively. Patients were cured after surgery, no recurrence six months follow-up. CONCLUSIONS: In patients with recurrent nasal polyps and chronic sinusitis, a preoperative CT scan can effectively detect the extent of residual disease and the anatomic abnormalities in the surgical field. This has implications for preoperative surgical design, particularly for functional endoscopic sinus surgery Important guiding role. The diagnosis of maxillary sinus osseal preoperatively mainly depends on the high-resolution CT axial and coronal two sections of the scan examination.
