The hypoglossal nerve (CN XII) is a pure motor nerve arising as a paired nerve from its nuclei in the medulla, exiting the skull base via the hypoglossal canal, and descending the neck to innervate the muscles of the tongue. Iatrogenic hypoglossal nerve palsy is uncommon, but cases have been reported, especially after airway management in general anaesthesia and suspension laryngoscopy. We report a case of iatrogenic hypoglossal nerve palsy post-suspension laryngoscopy, which was managed conservatively with full recovery after three months. We discuss the importance of minimal consent for suspension laryngoscopy and possible methods to prevent this uncommon yet unpleasant complication.
舌下神经（CN XII）是一条纯运动神经，由延髓中的核发出，成对出现，经舌下神经管离开颅底，沿颈部下行，支配舌肌。医源性舌下神经麻痹并不常见，但已有病例报道，尤其是在全身麻醉气道管理和支撑喉镜检查后。我们报告一例支撑喉镜检查后医源性舌下神经麻痹的病例，该病例采用保守治疗，三个月后完全恢复。我们讨论了支撑喉镜检查获得最低限度同意的重要性以及预防这种罕见但令人不适的并发症的可能方法。
