Abstract:
Objective To study the short-term impact of cleft palate repair surgery on hearing and middle ear function in infants .Methods Thirty-three infants with cleft palate who received cleft palate repair surgery from January 2013 to November 2014 in Peking Union Medical College Hospital were included in this study , in-cluding 22 male infants and 11 female infants .They were examined using distortion product otoacoustic emission (DPOAE), auditory brainstem response (ABR), 226 Hz probe-tone tympanometry before surgery and 1 -24 months after surgery .Results The mean age of the 33 infants (66 ears) at the time of surgery was 17 months (8.5-25 months).Sixty-four ears were examined with preoperative DPOAE , with 7 ears (10.9%) passed;postoperative DPOAE was performed in 56 ears, with 19 ears (33.9%) passed.The passing rate was significant-ly improved after operation ( P<0.01 ) .In the 54 ears for which both preoperative and postoperative DPOAE were conducted , 16 ears ( 29.6%) showed improved hearing .Sixty-three ears were examined with preoperative ABR, showing a mean hearing threshold of (43.73 ±13.65 ) dB nHL;62 ears were examined with postoperative ABR, showing a mean hearing threshold of (35.65 ±13.75 ) dB nHL, significantly improved compared with the preoperative threshold ( P<0.01 ) .In the 53 ears which received both preoperative and postoperative ABR , 29 ears (54.7%) showed reduced hearing thresholds .There was no significant difference in 226 Hz probe-tone tympanometry between preoperative and postoperative examinations ( P>0.05 ) .Conclusion In infants with cleft palate , short-term hearing improvement may be observed after repair surgery , while middle ear function may show no obvious improvement .
