Cochlear function after stapedectomy.

The short-term and long-term results of stapedectomy for eliminating the conductive element and improving the hearing in patients with otosclerosis are highly satisfactory all over the world. The delayed sensorineural hearing loss which continues after successful stapedectomy may be due to the operation itself or due to the natural history of the disease. The study was conducted on 80 patients with unilateral stapedectomy with a minimal follow-up period of 1 year. We found that bone conduction values at each frequency in operated ears were stable with marked improvement at 2,000 Hz, on the other hand, the bone conduction thresholds in non-operated ears significantly deteriorated (p less than 0.001). The speech discrimination score was significantly improved in the operated group (p less than 0.001). An explanation for the cochlear changes in operated and non-operated ears is presented.

Blink reflex: prognostic value in acute peripheral facial palsy.

The blink reflex (BR) has been studied during the first 2 weeks in 122 patients with Bell's palsy and Ramsay Hunt's syndrome. According to early BR (R1), the patients were divided into 3 groups: R1 less than or equal to 13 ms (16 cases); R1 greater than 13 ms (54 cases), and absent BR (52 cases). There was a remarkable tendency towards a satisfactory recovery from paralysis if BR occurred during the first 2 weeks from onset (p less than 0.001). In patients with normal BR, 93.7% had a satisfactory recovery, and in patients with delayed R1, the prognosis was still good: 86.8% had a satisfactory recovery. When the reflex was absent a bad prognosis was given in 55.8% of the patients. The BR and the severity of the lesions according to electroneurograms was tested in 111 patients and found to be significantly correlated (p less than 0.001). BR seems to be a useful index for predicting the prognosis in an early stage of the paralysis, however, more than one test should be performed at the same time to accurately establish the prognosis.
