Hypoglossal nerve palsy is a rare and also a multietiological disease. Nearly half of the 12th nerve palsies were caused by tumors and only 5% followed by surgery, usually after head and neck surgery such as carotid endarterectomy. In the reported cases, complications of oral intubation, bronchoscopy and use of laryngeal mask airway can be the causes of hypoglossal nerve palsy and the positional change of neck can be the cause of nerve injury. Using the Beach chair position for arthroscopy of the shoulder has the advantages of reducing traction injuries to the brachial plexus but also the possibilities of complications such as air embolism, complete airway obstruction and nerve injury. We report a case of transient hypoglossal nerve palsy after general anesthesia, using orotracheal intubation, for shoulder arthroscopic surgery in beach chair position.
