常見例句Objective To evaluate the anatomy and HRCT findings of foramen of nasal bone. 目的探討鼻骨孔的解剖基礎(chǔ)及影像學(xué)表現(xiàn)。Methods:45 patients were examined with nasal endoscope and X-ray or CT before the nasal bones repositioned and nasal septoplasty. 方法:45患者就診時均行鼻竇內(nèi)鏡檢查、鼻骨側(cè)位片和鼻竇CT檢查。The maxillary processes extend in a cephalad direction form the piriform aperture to the lacrimal crest, uniting with the frontal and nasal bones. 上頜骨額突由梨狀孔和淚嵴向頭側(cè)方向伸出,與額骨和鼻骨相接。Consisting of the paired nasal bones and the ascending frontal process of the maxilla, the vault acts as a cantilever, supporting the upper nose and the upper lateral cartilages. 骨性穹隆由一對鼻骨和上頜骨額突構(gòu)成,好似一個支架,支撐著鼻上部和上外側(cè)軟骨。The nasal bones actually overlap the cephalic upper lateral border by 6 to 8 mm, thus producing a firm adherence between both structures, enhancing support. 實際上鼻骨覆蓋了約6到8毫米頭側(cè)上外側(cè)軟骨,從而產(chǎn)生牢固的附著并提升支撐力。With the two cohorts combined, nasal bone absence had a sensitiity of 47.6% and specificity of 100%. 兩個參數(shù)同時考慮時,對鼻骨缺失的診斷敏感度達(dá)到47.;6%25,特異性達(dá)到100%25。 返回 nasal bones
