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.
喉罩致颅神经损伤罕见但后果严重，使用喉罩行气管插管时应预防神经损伤。我们报告 1 例手部手术后出现舌麻木、言语不清和吞咽固体食物轻微困难的女性患者，诊断为单侧舌神经和舌下神经损伤。极度头旋转、相对较小的口腔和新型喉罩下部刚性结构宽大可能导致颅神经损伤。
