In the literature the possibility of a pressure trauma to the hypoglossal nerve between the root of the tongue and the ligamentum stylohyoideum is discussed. A recent in vivo study examined the effects of forced reclination of the head on the nerve.
A left sided hypoglossal nerve paralysis occurred in a patient after an endoscopically controlled endonasal operation under general anesthesia with transoral intubation.
Clinically and electrophysiologically the palsy seemed to be transient due to neurapraxia. An X-ray of the neck performed after the operation revealed a calcification of the left ligamentum stylohyoideum. All the other diagnostic studies (ultrasound of the neck, neurological examination, serological tests, and CT scan of the head) did not show any abnormalities. This is the first time, that a postoperative hypoglossal nerve palsy has been observed, which could not be explained by extensive stretching or pressure.
We believe that the short pressure of the Mcintosh spatula produced the hypoglossal nerve palsy described.
文献中讨论了舌根部与茎突舌骨韧带之间的舌下神经发生压力性损伤的可能性。最近的一项体内研究检查了头部强迫后倾对该神经的影响。
一名患者在全身麻醉下经口插管进行内镜控制的鼻内手术后出现左侧舌下神经麻痹。
临床和电生理检查显示，由于神经失用，麻痹似乎是暂时的。术后颈部X线检查显示左侧茎突舌骨韧带钙化。所有其他诊断研究（颈部超声、神经学检查、血清学检查和头部CT扫描）均未显示任何异常。这是首次观察到术后舌下神经麻痹，且无法用广泛的拉伸或压力来解释。
我们认为，麦金托什压舌板的短暂压迫导致了所描述的舌下神经麻痹。
