Abstract
Cranial nerve injury by a laryngeal mask airway is rare but a serious complication. The nerve injuries must be prevented during the intubation using a laryngeal mask airway. We report a female patient who complained of tongue numbness, slurred speech, and slight difficulty in swallowing solid food after a hand surgery. She was then diagnosed with unilateral lingual nerve and hypoglossal nerve injuries. Extreme head rotation, relatively small oral cavity, and wide rigid composition at the lower part of the novel laryngeal mask probably resulted in cranial nerve injury.

Resumo
A lesão do nervo craniano por uma máscara laríngea é rara, mas uma complicação séria. As lesões nervosas devem ser evitadas durante a intubação com máscara laríngea. Relatamos uma paciente do sexo feminino que se queixou de dormência na língua, fala arrastada e leve dificuldade para engolir alimentos sólidos após uma cirurgia na mão. Ela foi então diagnosticada com lesão não-bilateral do nervo lingual e do nervo hipoglosso. Rotação extrema da cabeça, cavidade oral relativamente pequena e composição ampla e rígida na parte inferior da nova máscara laríngea provavelmente resultaram em lesão do nervo craniano.
