FU = follow-up; ND = not done; Prom Stim = promontory stimulation; + = positive.

Postimplantation testing for this patient was performed at another center, and the standard test battery was not performed. For this patient, the postoperative pure tone average was 20 dB, and word recognition scores were 80% without visual cues (also known as open-set speech recognition) and 92% with visual cues.
