【摘要】 对100个成人颅骨及10个半颅的蝶窦进行了研究。全鞍型较多见,占75±4.33％,且多见于男颅(P<0.01)。窦腔双房出现率为88±3.25％,单窦占5±2.18％。窦中隔有44±4.96％偏左,28±4.4％偏右。前鼻棘至蝶窦口连线与硬腭水平线形成的夹角,平均34.76°±0.39。x线片上可用sinA=a/c公式求取,以作为经蝶窦作垂体瘤手术的指标。更多还原

【Abstract】 The Sphenoidal sinus of 100 adult skulls and ten of half-skulls have been studied. It shows that the full sellaturcica is the most abundant in the types of the sphenoidal sinus(75±4.33%) which are less seen in female than in male. the percentage of double sinuses is 88±3.25%, single sinuses is 5±2.18% in which the septums of single sinus are absent, mul-tsinuses are 7±2.55%. The septums of the sphenoidal sinuses slanted to the left are more frequence(44±4.96%) than to the right(28±4.49%). The angle from the anterior nasal spine to the orifice of the sphenoidal sinus and to the horizontal line of hard palate is 34.76°±0.39 in average. it can be used in the operation of pituitary tumour through the sphenoidal sinus as a direct figure.更多还原
