目的探讨阻塞性睡眠呼吸暂停低通气综合征(Obstructive Sleep Apnea-Hypopnea Syndrome;OSAHS)儿童的听功能状态。方法选择OSAHS患儿65例(130耳),根据睡眠呼吸紊乱指数(AHI)分为2组:OSAHS轻度组(10次/h>AHI≥5次/h)和OSAHS中重度组(AHI≥10次/h),作为实验组。并选择正常儿童20例(40耳)作为对照组。均行纯音测听、声导抗检查及纤维鼻咽喉镜检查,并对声导抗测试中鼓室导抗图为“A”型耳,进行听觉脑干诱发电位(ABR)和瞬态诱发耳声发射(TEOAE)检查。与对照组比较,进行统计学分析。结果 OSAHS患儿59例(118耳)正常儿童对照组20例(40耳)进入统计分析;①、125~8000 Hz各频率气导听阈,OSAHS轻度组与对照组比较无统计学意义(P>0.05),中重度OSAHS组与对照组比较均有增高,差异有统计学意义(P<0.05)。②、OSAHS轻度组鼓室压图异常率51.52%(34/66),OSAHS中重度组鼓室压图异常率62.75%(31/52),组间比较无统计学差异(P>0.05),与对照组比较均有统计学差异(P<0.05);③、鼓室导抗图为“A”型的轻度及中重度OSAHS患儿的TEOAE通过率,与对照组比较差异均有统计学意义(均P<0.01)。④、鼓室导抗图为“A”型的轻度OSAHS患儿ABR听阈、各波潜伏期和波间期与对照组比较无统计学差异(P>0.05);鼓室导抗图为“A”型的中重度OSAHS患儿波Ⅰ、Ⅴ潜伏期及波Ⅰ-Ⅲ、Ⅰ-Ⅴ波间期比对照组延长,Ⅴ波反应阈亦较对照组提高,差异有统计学意义(P<0.05)。⑤、鼓室压曲线异常分别与语言频率平均听阈、腺样体肥大程度、AHI、最低血氧饱和度相关;⑥、对鼓室压图为“A”型的53耳及对照组40耳进行Logis-tic回归分析:腺样体肥大及AHI是OSAHS患儿耳蜗及听觉神经通路损害的危险因素。结论儿童OSAHS易出现中耳功能异常导致的传导性听力损失,同时中重度OSAHS患者还可能出现缺氧导致的耳蜗及听觉脑干的损害。 相似文献

The paper presents preliminary results of Eustachian tube dysfunction treatment with the use of vibroaerosols in adult patients. 21 patients aged 16-73 y.o. (mean age 49 y.o) have been included in the study. The treatment included inhalation of medicines individually selected for the patient, based on the results of the physical examination. The patients have been divided into 2 groups, depending on the type of tympanogram. Group I included patients with type A tympanogram and abnormal Eustachian tube patency test result. Group II comprised of patients with type B or C tympanogram and abnormal Eustachian tube patency test result. After treatment, subjective improvement has been observed in 88.9% of the ears, objective improvement in 61.5% of the ears. In group II, objective improvement observed by the change of tympanogram has been observed in 85% of ears. Lack of correlation between objective and subjective improvement have been observed in 26% of the ears. In 11.1% of the ears no benefit from treatment has been observed. The correlation between subjective and objective improvement has been observed in 74% of ears. It appears that treatment with the use of vibroaerosols is beneficial for patients with Eustachian tube dysfunction. 相似文献

Tympanograms were obtained from 166 ears of 83 college students with normal middle ear function. Three measures of gradient were determined for each tympanogram: Gdif, Gratio, and GdP. Each gradient measure was evaluated for its potential usefulness in discriminating between ears with and without effusion. Gdif was found to be a fairly poor choice for gradient. Because it correlated so highly with static admittance, little additional information would be gained about tympanogram shape. The two other measures, Gratio and GdP, appeared to be roughly equivalent and would be preferred over Gdif as measures of tympanogram shape. 相似文献

Objective: To investigate the diagnostic value of distortion product otoacoustic emission (DPOAE) together with tympanometry in assessing otitis media with effusion in children.Methods: Three hundred and thirty-nine patients, who were diagnosed with obstructive sleep apnea–hypopnea syndrome (OSAHS) and prepared to undergo adenotonsillectomy and had a unilateral or bilateral type ‘B’ or ‘C’ tympanogram were enrolled in this study. Patients were divided into the following four groups: Group 1, type ‘B’ tympanogram with positive DPOAE; Group 2, type ‘B’ tympanogram with negative DPOAE; Group 3, type ‘C’ tympanogram with positive DPOAE and Group 4, type ‘C’ tympanogram with negative DPOAE.Results: Tympanometry showed a type ‘B’ pattern in 467 ears and type ‘C’ pattern in 163 ears. Among 163 ears with type ‘C’ tympanogram, negative DPOAE results were seen in 96 ears. Group 4 (56/96) had a significant high rate of middle ear effusion than Group 3 (14/67) (p?.05). In patients with a type ‘C’ tympanogram, those with a low compliance value (~0.25?ml), concurrent chronic tonsillitis and large tonsils are likely to have middle ear effusion.Conclusions: DPOAE could be a great help in screening for middle ear effusion in patients with a type ‘C’ tympanogram. 相似文献

The Carhart notch is a dip in the bone conduction at 2000 Hz without a corresponding dip in the air conduction. The main objective of this study was to establish how reliable is the presence of the Carhart notch in a preoperative audiogram in predicting the presence of glue at myringotomy. A prospective study has been carried out in 50 children presenting with glue ear to find out the association between the Carhart notch and the presence of glue at myringotomy. Children were seen before the operation and an audiogram and tympanogram were carried out. Myringotomy was carried out in 95 ears and the presence or absence of glue was recorded. The significance of the air-bone gap and the type of tympanogram in predicting a middle ear effusion were also examined. The audiograms of 37 ears showed a Carhart notch; of these, 36 ears were noted to have glue ear. The correlation between the presence of a Carhart notch in the preoperative audiogram and the presence of glue at myringotomy was found to be significant (P < 0.001) (chi-square test). Using the decision rule that the presence of a Carhart notch predicts the presence of glue, the following operating characteristics were determined: correct, 83 ears (87.4%); false positive, one ear (1.1%); false negative, 11 ears (11.6%). The presence of a Carhart notch was found to be a strong predictor of the presence of glue at myringotomy. 相似文献

OBJECTIVE: Minimal change nephrotic syndrome (MCNS) is characterized by the onset of NS (Nephrotic Syndrome) without systemic disease, hypocomplementemia, or other serious signs of renal disease. Hearing status is not very well known in MCNS. Our objective was to address this question and to find out remission and relapse periods of the syndrome would affect the hearing of the patients. METHODS AND PATIENTS: Otologic status of 26 children with clinical MCNS was investigated in relapse and remission periods using audiometry and tympanometry. The pure tones that were obtained at the frequencies 250, 500, 1000, 2000, 4000 and 6000 Hz were noted. Pure tone averages (PTAs) were calculated at 500, 1000, 2000 and 4000 Hz frequencies. RESULTS: In both remission and relapse periods, PTA of the patients did not change and was 13 dB. The frequency specific pure tone results were not significantly different between the right and left ears of the patients as well as between the remission and relapse periods (p > 0.05). In the relapsing and remission periods, type A tympanogram was encountered in 86.4% and 92.3% of the ears, respectively. Type B tympanogram was encountered in 11.5% and 3.8% of the ears in the relapsing and remission periods, respectively. Type C tympanogram was encountered in 3.8% of the ears both in the relapsing and remission periods. Differences between the tympanometry results were not significant (p > 0.05). CONCLUSION: MCNS in childhood is not associated with an alteration in the hearing status, both in remission and relapse periods of the disease. 相似文献
