PURPOSE: The aim of this study was to explore the value of brainstem auditory evoked potentials in the diagnostic assessment of dysphagia after craniocerebral injury.
METHODS: To investigate the role of brainstem auditory evoked potentials (BAEPs) in dysphagia diagnosis, we prospectively analyzed BAEP findings and gold-standard diagnoses in 106 patients with head injury. Inclusion criteria: ① Age 18-70 years old; ② Diagnosed by Chinese Expert Consensus on Evaluation and Treatment of Dysphagia. Exclusion criteria: ① Patients with a Glasgow coma scale score ≤8 and patients who cannot be managed with intervention; ② Previous comorbidities that may affect swallowing function.
RESULTS: A total of 65 males and 41 females patients were enrolled. The positive rate of BAEP in moderate to severe dysphagia was 86.96%, which was significantly higher than that in the mild dysphagia group (45.95%; p < 0.01). 60 patients were BAEP-positive and moderate-to-severe dysphagia patients, and considered neurogenic dysphagia, 46 patients were BAEP-negative, and considered non-neurophagia. The AUC of BAEP diagnosis of moderate to severe dysphagia was 0.705.
CONCLUSION: BAEP can be used as an accurate diagnostic method for nerve injury, it is helpful to identify whether it is a neurological dysphagia.
