[Stapedius reflex. 2. Latency periods of the stapedial reflex]

The reflex thresholds and initial latency times of the stapedial reflex of 50 patients with normal hearing and cochlear hearing loss were examined using Madson ZO 73 equipment. The following results were obtained: 1. The initial latency times of the stapedius reflex diminish proportional to the supra-threshold loudness. 2. No significant difference of the latency times was found between 0.5, 1, 2 and 4 kHz. 3. The initial latency times of patients with positive recruitment (cochlear hearing loss) do not differ from those of patients with normal hearing.
