Clinical Characteristics of Dizziness Associated with Acute Peripheral Facial Palsy.

Abstract

Background and ObjectivesWe aimed to assess the clinical significance of dizziness associated with acute peripheral facial palsy (APFP).Subjects and MethodsMedical 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.ResultsIn 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.ConclusionsPatients 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.
