Abstract
Objective To investigate the characteristics of clinical hearing of patients with cleft palate, and to evaluate the ef⁃fects of sex;age;and surgery on the hearing results.Methods 256 cases of cleft palate ,including 243 cases who had never re⁃ceived cleft-closure operation and 13 cases who had received cleft-closure operation for at least 5 years. To evaluate the ef⁃fects of sex, we investigated 174 cases(male76, and female 98) who were under 2 years (≤2 y ), they were divided into 2 groups;to evaluate the effects of age, the 243 cases with no operation history were divided into group A(≤2 y );group B (>2 y≤6 y);and group C (>6 y);to evaluate the effects of surgery, we compared group C to 13cases who had received cleft-closure opera⁃tion (group D), because the ages of these two groups were similar. For DPOAE, at least the pass of≥3 frequencies at 1818;2730;3616;5434Hz was defined as pass. For AIM, type A was considered to be normal. Part of these cases were also tested by ABR, and the threshold of waveⅴ≥35 dB nHL was received to be abnormal.Results 174 Patients (≤2 y, group A)showed no differences in DPOAE, AIM and ABR between sexes (p>0.05). Between group A and group C, DPOAE, AIM and ABR showed significant difference (p<0.05), Between group A and group B, DPOAE and ABR showed significant difference (p<0.05), but AIM showed no significant difference (p<0.05). Between group B and group C, only DPOAE showed significant difference (p<0.05), AIM and ABR showed no significant difference (p>0.05). Between group C and group D, whose ages were similar, only AIM and ABR showed significant difference(p<0.05). In group A,B and C together, the pass rate of DPOAE was higher than the normal rate of ABR (p<0.05). Conclusion Sex has no influence on hearing results of patients with cleft palate. In this kind of patients, there is a tendency that the hearing results become better with the increasing of age. Cleft palate surgery is helpful in the recovery of hearing loss. DPOAE is of easy and relatively rapid manipulation, and steady results, it can be a useful meth⁃od for the hearing test for patients with cleft palate, especially in infants. But to identify the type and extend of hearing impair⁃ment, other hearing tests should also be considered.关键词
