Prognostic value of the blink reflex test in Bell’s palsy and Ramsay-Hunt syndrome

This study was designed to evaluate the prognostic value of the blink reflex (BR) test in patients with Bell’s palsy (BP) or Ramsay Hunt syndrome (RHS). The House–Brackmann (HB) grade of patients diagnosed with BP and RHS was determined at first visit and 3 months later. Final HB grade III–VI was de...

Description
Summary:This study was designed to evaluate the prognostic value of the blink reflex (BR) test in patients with Bell’s palsy (BP) or Ramsay Hunt syndrome (RHS). The House–Brackmann (HB) grade of patients diagnosed with BP and RHS was determined at first visit and 3 months later. Final HB grade III–VI was defined as an incomplete recovery. Factors evaluated as prognostic of poor recovery included electroneurography (ENoG) degeneration rate (DR)>90%, and absence of BR. Rates of complete and incomplete recovery were calculated and the associations between prognostic factors and recovery were determined. Of the 129 included patients, 98 (76%) had BP and 31 (24%) had RHS. Absence of BR and low mean ENoG value were significantly associated with incomplete recovery in both the BP and RHS groups (p
