Abstract: Objective　To explore prevalance of hearing loss and hearing loss characteristics in different frequencies in patients after cleft palate surgery. Methods　50 subjects with repaired cleft palate and 36 subjects with unrepaired cleft palate were recruited to conduct a pure tone assessment binaurally. We observed hearing loss conditions and compared hearing threshold of 100 ears of 50 subjects with repaired cleft palate in different frequencies. Results　Hearing loss was found in 14 subjects (28.00%) of 50 subjects with repaired cleft palate, and 15 subjects (41.67%) of 36 subjects with unrepaired cleft palate. 84.21% ears with abnormal hearing in subjects with repaired cleft palate (16 ears out of 19 ears) had mild and moderate hearing loss. In the 36 postoperative patients with normal hearing ability, 36.11%,16.67% and 11.11% were identified with hearing loss in the frequencies of 250Hz, 500Hz and 6kHz respectively. Conclusion　Mild to moderate hearing loss was found in some subjects with repaired cleft palate. Mild hearing loss in low and high frequencies was also reported among normal hearing subjects. This indicates that factors going against hearing recovery still exsit to patients with repaired cleft palate. Careful attention should be drawn to ear disease of the patients with repaired cleft palate.
