This study was performed to determine the location of the natural ostium of the sphenoid sinus relative to the intact superior turbinate.
Forty-seven cadaveric specimens were examined. Mucosa over the sphenoethmoidal recess, superior turbinate, and posterior ethmoid was left intact. The position of the sphenoid sinus natural ostium relative to the superior turbinate was identified.
The sphenoid ostium was identified in all specimens. In all specimens, the sphenoid ostium was found to be medial to the intact superior turbinate, notwithstanding lateral deflection of the posterior few millimeters of the superior turbinate in some cases.
The superior turbinate is an excellent landmark for the sphenoid sinus natural ostium. Previous observations of the ostium positioned lateral to the superior turbinate may have been caused by stripping of the superior turbinate mucosa before measurements were taken. In the intact specimen, the sphenoid ostium is reliably found medial to the superior turbinate.
本研究旨在确定蝶窦自然开口相对于完整上鼻甲的位置。
检查了47个尸体标本。蝶筛隐窝、上鼻甲和后筛窦的黏膜保持完整。确定蝶窦自然开口相对于上鼻甲的位置。
在所有标本中均识别出蝶窦开口。在所有标本中，尽管在某些情况下上鼻甲后几毫米向外侧偏斜，但蝶窦开口位于完整上鼻甲的内侧。
上鼻甲是蝶窦自然开口的良好标志。先前观察到开口位于上鼻甲外侧，可能是由于在测量前剥脱了上鼻甲黏膜所致。在完整标本中，蝶窦开口可靠地位于上鼻甲内侧。
