ABG median was lower in ears with PF retraction (6.25 dB HL) than PT retraction, isolated (15 dB HL) or not (13.75 dB HL; p < 0.05). The ABG pure-tone average median was higher when PT was involved. We found a significant correlation between the retraction severity and worsening of AC and ABG thresholds, only for PT. The ABG pure-tone average median was higher when PT was involved. We found a significant correlation between the retraction severity and worsening of AC and ABG thresholds, only for PT. To study the pathophysiology of Charcot-Marie-Tooth disease (CMT) with auditory neuropathy (AN) and to follow up cochlear implant or hearing aid use over the long term. Clinical capsule report. Two adult CMT patients with AN. Cochlear implantation for case 1 and hearing aid use for case 2. Case 1 was a 50-year-old man who was diagnosed as having CMT at 15 years of age. He noted his hearing impairment at the age of 22. We considered that he had AN as a complication on the basis of the findings of normal distortion product otoacoustic emission and the absence of auditory brainstem response on both ears. We performed cochlear implantation for his progressive hearing loss when he was 41 years old. His postoperative discrimination scores for words and sentences in the CI-2004 test 4 years after cochlear implantation were 80% and 93%, respectively. His sound discrimination scores were 23/24 in the test with picture matching and 9/24 in that without picture matching 8 years after cochlear implantation.Caseations). The symptoms and courses vary among patients with CMT. Therefore, the selection of an appropriate intervention for hearing loss depending on the severity and course is very important. Adult cochlear implant candidates would self-report their executive functioning abilities as poorer than normal-hearing peers. These executive function abilities
