Ear examinations were performed at postoperative months 3, 6,12, and 24, and pure-tone average
(PTA)for air-conduction threshold values and air-bone gaps (ABGs) were evaluated at 0.
We computed pure-tone average
(PTA) at speech frequencies (0.
To determine which factors could influence symptom improvement, multiple linear regression analyses of the improvement rate were performed with various factors: pure-tone average
of the affected side, tinnitus duration, initial tinnitus loudness, initial tinnitus awareness score, and initial THI.

MAIN OUTCOME MEASURE: Hearing loss, defined as audiometric threshold values of at least 16-dB hearing level based on a low or high pure-tone average
defined hearing loss as "a pure-tone average
of thresholds at 500, 1,000, 2,000, and 4,000 Hz greater than 25 dB" in the worse ear .
The researchers evaluated hearing impairment as a pure-tone average
greater than 25 decibels hearing level in either ear, and also measured word recognition at different sound levels and with male and female voices.
Successful treatment was defined as at least a 50% recovery of four-frequency pure-tone average
relative to the unaffected, contralateral ear.
The mean conductive hearing loss was measured, and the mean value of the conductive hearing loss at all frequencies (500 to 4,000 Hz) and the pure-tone average
(speech recognition zone) was calculated as the mean of CHL at 500, 1,000, and 2,000 Hz.
Participants' demographics and hearing loss (as graded by the ASHA degree of severity of hearing loss) Participants, N 25 Age (years), mean (range) 43 (15-86) Age distribution (years), n 15-20 4 21-40 7 41-60 6 61-80 8 Gender, n Male 13 Female 12 Ears with PTA (dB), n [less than or equal to] 25 (normal) 24 26-40 (mild loss) 18 41-55 (moderate loss) 5 56-70 (moderate to severe loss) 2 71-90 (severe loss) 1 [greater than or equal to] 91 (profound loss) 0 ASHA = American Speech-Language-Hearing Association; PTA = pure-tone average
It is defined as a pure-tone average
(PTA) of thresholds at 500, 1000, 2000, and 4000 Hz greater than 25-dB hearing level (dB HL) in the better ear.
