ABSTRACT
BACKGROUND AND OBJECTIVES: We aimed to assess the clinical significance of dizziness associated with acute peripheral facial palsy (APFP). SUBJECTS AND METHODS: Medical records of patients who visited an otorhinolaryngology clinic at a university hospital and were admitted for treatment of APFP between 2014 and 2016 were thoroughly reviewed. RESULTS: In total, 15.3% (n=15) of patients had dizziness. Continuous, rotatory dizziness without exacerbating factors was most common and frequently accompanied by nausea/vomiting. Dizziness disappeared within 1 week during the hospitalization period. Patients with Ramsay Hunt syndrome (31.0%) had dizziness more frequently than those with Bell’s palsy (8.7%). In addition, higher hearing thresholds and pain around the ear was reported more often in dizzy patients (p < 0.05). Logistic regression analysis revealed that the initial House-Brackmann grade of facial paralysis was solely associated with final recovery, but dizziness was not associated with prognosis. CONCLUSIONS: Patients with APFP may have transient dizziness in the early stage, which may be more frequently accompanied by worse hearing thresholds and/or pain around the ear. However, these symptoms including dizziness seem to be unrelated to final prognosis.
