Expanding Indications for Cochlear Implantation: Unilateral Hearing Loss

---

1.  What do patients with unilateral hearing loss experience as compared to normal hearers? Poorer speech understanding in noise Poorer localization Poorer quality of life All of the above

2.  What are the currently approved technologies for patients with unilateral hearing loss? Conventional hearing aids Bone-conduction devices CROS hearing aids All of the above

3.  What was the difference in speech perception performance for AzBio sentences in the S0NContra condition between the preoperative unaided performance and 12-month aided performance? Participants had better speech perception in the unaided condition Participants had better speech perception in the aided condition There was no difference between speech perception performance in the unaided and aided conditions Participants were not tested at the 12-month interval in the aided condition

4.  What was the difference in localization between the preoperative unaided performance and 12-month aided performance? Participants had more accurate localization in the unaided condition Participants had more accurate localization in the aided condition There was no difference between localization in the unaided and aided conditions Participants were not tested at the 12-month interval in the aided condition

5.  At what interval did participants first demonstrate a significant improvement on the localization measure as compared to preoperative performance? 1-month 3-month 6-month 12-month

6.  At what interval did participants demonstrate stable performance on the localization measure? 1-month 3-month 6-month 12-month

7.  How did perceived tinnitus severity change over the study period? There was no difference in the perceived tinnitus severity at each interval Perceived tinnitus severity reportedly improved over time with device use Perceived tinnitus severity reportedly worsened over time with device use Tinnitus severity was not measured as part of the study protocol

8.  How many participants continued to use their CI during the study period? 5 10 15 20

9.  What variables might have contributed to the outcomes observed in the present study cohort? Electrode array length Mapping techniques Aural rehabilitation All of the above

10.  What participant variables might have contributed to the outcomes observed in the present study cohort? Motivation Duration of daily device use Listening environment All of the above
