Cranial Polyneuritis and Bell Palsy

Auditory Brain Stem Response Abnormalities in Patients with Bell's Palsy

“…:1. 16 However, the present study does not clarify whether Bell's palsy may be a multifocal neuropathy or a manifestation of a single lesion in the brain stem. It should be emphasized that the auditory pathways in the brain stem, particularly the superior olivary nucleus, are adjacent to the facial nucleus and facial tracts.…”

Attenuated cranial polyneuropathy

“…Additional cranial nerve involvement in association with facial palsy has been noted earlier 2 , 3 , 4 . These authors have proposed a viral aetiology to explain the involvement of multiple cranial nerves, on the basis of alterations in the viral titres.…”

Auditory brain-stem response audiometry in patients with Bell's palsy

“…In no instance was there evidence of tone decay exceeding 5 dB, nor asymmetry between ears on the SISI test. Speech discrimination at the most comfortable loudness level was between 97 and 100% for both ears of each patient, and there was no consistent pattern of reduced discrimination ability a t 95 dBHL, although several patients Absent acoustic reflex and abnormal ABR 6 18.8 Paretic side affected 3 Bilaterally affected 2 Paretic side affected 3 Bilaterally affected did complain of discomfort when the intense speech was presented to the ear with an absent acoustic reflex. ABR results for 1-111, 111-V, I-V interpeak latencies were abnormal in 14 (43.7%) of our patients.…”
