Abstract:
The presence of a thyroid foramen in the thyroid cartilage of the larynx is not uncommon. It may be occluded by a fibrous layer, or it may be an abnormal path for the neurovascular bundle of the larynx. The superior laryngeal nerve and the superior laryngeal vessels are the most common contents of the thyroid foramen. During the observation of the skeleton of a 32-year-old female, we found a completely ossified laryngeal framework with bilateral double thyroid foramina. Three of the foramina were circular, and one was oval in shape. This is a very rare anatomical variation. Deep knowledge of the thyroid cartilage anatomy is mandatory during laryngeal and thyroid surgery. The meticulous dissection of laryngeal vessels and nerves is of paramount importance to control bleeding and avoid postoperative neurological sequelae due to nerve injury. The surgeon should be aware that in the whole length of the oblique line of the thyroid cartilage, a thyroid foramen may be detected.
摘要:
在喉的甲状软骨中存在甲状腺孔并不少见。它可能被纤维层遮挡,或者它可能是喉神经血管束的异常路径。喉上神经和喉上血管是甲状腺孔最常见的内容物。在观察一名32岁女性的骨骼时,我们发现了一个完全骨化的喉框架,双侧双甲状腺孔。三个孔是圆形的,一个是椭圆形的。这是一种非常罕见的解剖学变异。在喉和甲状腺手术中,必须深入了解甲状软骨的解剖结构。喉血管和神经的细致解剖对于控制出血和避免由于神经损伤引起的术后神经后遗症至关重要。外科医生应该意识到,在甲状软骨斜线的整个长度上,可以检测到甲状腺孔。
