We investigated the bulging and dehiscence of neurovascular structures in the sphenoid sinus and their relationships to the pneumatization of the sphenoid sinus.
One hundred sagittally hemisected cadaveric heads were examined. The degree of pneumatization of the sphenoid sinus was determined. Bulging and dehiscence of the internal carotid artery (ICA), optic nerve, maxillary nerve, and vidian nerve were examined, and the distances between these structures and the anterior or superior wall of the sphenoid sinus were measured. Additionally, the degree of bony thickness over these structures was determined.
The prevalences of bulging of the optic nerve, segments 1 and 3 of the ICA, and the maxillary and vidian nerves were 56%, 34%, 65%, 41%, and 52%, respectively. The greater the degree of pneumatization, the more frequently did the structures bulge into the sphenoid sinus. The optic nerve was found to be in close proximity to the anterior and superior walls of the sphenoid sinus. The bone over the surrounding structures was very thin, especially for the complete sellar type.
The prevalence of bulging of the optic nerve, the ICA, and the maxillary and vidian nerves increased in proportion to the degree of sphenoid sinus pneumatization.
我们研究了蝶窦内神经血管结构的膨出和裂开情况及其与蝶窦气化的关系。
检查了100个经矢状面半切的尸体头部。确定蝶窦的气化程度。检查颈内动脉（ICA）、视神经、上颌神经和翼管神经的膨出和裂开情况，并测量这些结构与蝶窦前壁或上壁之间的距离。此外，确定这些结构上方的骨质厚度。
视神经、ICA的第1段和第3段、上颌神经和翼管神经的膨出发生率分别为56%、34%、65%、41%和52%。气化程度越高，结构膨入蝶窦的频率越高。发现视神经紧邻蝶窦的前壁和上壁。周围结构上方的骨质非常薄，尤其是完全鞍型。
视神经、ICA、上颌神经和翼管神经的膨出发生率与蝶窦气化程度成正比增加。
