The frontal sinus ostium is frequently difficult to recognize because of anatomical structures that hide it. The objective of the present study was to identify and describe the frontal recess anatomy that impairs the endoscopic recognition of the frontal sinus ostium.
A prospective study was conducted by consecutive endoscopic dissections of 32 cadavers (59 sides), 10 (31.25%) females and 22 (68.75%) males. After resection of the lower portion of the uncinate process, with preservation of its upper insertion, we evaluated which anatomical structures needed to be removed for complete visualization of the frontal sinus ostium.
Visualization of the frontal sinus ostium after resection of the lower portion of the uncinate process was possible in only 11 (18.64%) nasal cavities. The uncinate process (terminal recess) was the main anatomical structure that impaired the recognition of the frontal sinus ostium, present in 45 (76.27%) nasal cavities, followed by the ethmoid bulla (16.95%) and agger nasi cells (6.78%).
由于存在隐藏额窦开口的解剖结构,额窦开口常常难以辨认。本研究的目的是识别并描述影响额窦开口内镜识别的额隐窝解剖结构。
对32具尸体(59侧)进行连续内镜解剖,开展一项前瞻性研究,其中女性10例(31.25%),男性22例(68.75%)。在切除钩突下部并保留其上部附着后,我们评估了为完整显露额窦开口需要移除哪些解剖结构。
仅11个(18.64%)鼻腔在切除钩突下部后能够显露额窦开口。钩突(终末隐窝)是妨碍识别额窦开口的主要解剖结构,在45个(76.27%)鼻腔中存在,其次是筛泡(16.95%)和鼻丘气房(6.78%)。
