Acoustic Reflex and Loudness Discomfort in Acute Facial Paralysis

Clinical prognostic factors in patients with idiopathic peripheral facial nerve paralysis (Bell’s palsy)

“…We concluded that sex, side of palsy, hypertension and timing of the treatment did not have any effect on the prognosis. Absence of stapedius reflexes are one of the most known bad prognostic factor in PFNP [21]. Our results are supporting the poor treatment outcomes with absence of stapedius reflexes.…”

Characterization of Acoustic Reflex Latency in Females

“…Their results indicated that statistically significant differences existed between the normal and sensory neural groups not in onset latency, but in the measures of offset latency. These results are consistent with Norris et al, [21] study, showing lower Reflex Relaxation Index (RRI) among subjects with sensory neural disorder. Borg [23] pointed out that accurate measurements of the reflex latency are best achieved with stimuli having rise times of 10 ms or less.…”

The stapedius reflex in idiopathic facial palsy

“…The time difference between recovery of stapedius and facial muscle movements can be explained by the different lengths of axonal regrowth required. Citron and Adour (1978) also found that in most patients the return of the reflex was observed prior to that of any other aspect of facial nerve function, including the NET. Koike et al (1977) published the first report correlating prognosis and stapedial reflex test findings.…”
