Foreign Language Syndrome Following Extraction of Wisdom Teeth Under General Anesthesia: A Case Report

Foreign language syndrome (FLS) is a rare phenomenon described as transient fixation on a second language following anesthesia administration. There have only been 12 previously reported cases of FLS and none involving female patients or oral and maxillofacial surgery (OMS). While volatile anesthetics were administered during at least 2 cases, at minimum 5 cases occurred without volatile anesthetics - instead manifesting with IV sedation medications commonly used with OMS outpatient procedures (ie, midazolam, fentanyl, and propofol). In our case, a healthy 21-year-old female underwent extraction of wisdom teeth under general anesthesia and developed FLS. Our purpose is not to elucidate the poorly understood pathophysiology of FLS but raise awareness of its potential following OMS procedures. FLS may be difficult to diagnose but appears to be self-limiting and typically resolves within approximately 24 hours. No stroke workup is warranted, and discharge home is likely appropriate with phone follow-up the following day.
