Abstract
To examine the progress from suspected hearing loss to rehabilitation, we conducted a survey involving 50 patients at the Department of Otolaryngology, Yamaguchi University Hospital, who underwent a hearing test or consultation for rehabilitation and whose progress concerning hearing loss we were able to observe. With regard to the 14 patients who had received hearing screening for infants, their rehabilitation had started at less than 1 year old regardless of the degree of hearing loss. Concerning the 26 patients who had not received hearing screening, those with severe of excessively severe hearing loss had started their rehabilitation at an average age of 21 months old, while patients with slight or moderate hearing loss had stated their rehabilitation at an average age of 4 years and 9 months old.Next, we assessed the speech recognition and language development of the 19 patients we were able to observe over a long period. With regard to the 19 patients who were assessed using the Wechsler Intelligence Scale for Children-Fourth Edition（WISC-Ⅳ），we observed a correlation between their composite score for the Verbal Comprehension Index（VCI）and that for the Perceptual Reasoning Index（VCI）．
