Abstract:
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.
