儿童分泌性中耳炎危险因素分析

目的 探讨武汉市部分幼儿园儿童分泌性中耳炎的危险因素,并与相关文献分析比较.方法 调查武汉市部分幼儿园3～6岁的儿童,对其进行常规耳鼻咽喉科体检,电耳镜检查鼓膜结合声导抗测试,并问卷调查母亲牛育年龄、生产情况、喂养情况,家庭吸烟史,耳科病史,鼻漏,喷嚏,鼻塞,睡眠打鼾,扁桃体炎发作情况等.结果 144例分泌性中耳炎患儿和288例对照者进行危险因素统计学分析,发现鼻塞(OR=2.60,P=0.002),鼻涕(OR=1.442,P=0.003),硬腭高拱(OR=4.411,P＜0.0001),急性中耳炎病史(OR=1.77,P=0.025)是患病的危险因素.进行多因素同归分析后发现喂养情况(OR=0.746,P=0.047),鼻塞(OR=2.56,P=0.003),硬腭高拱(OR=4.35,P＜0.001),鼻炎(OR=1.397,P=0.098),急性中耳炎病史(OR=1.735,P=0.032)为分泌性中耳炎的影响因素.结论 中耳炎病史是分泌性中耳炎的危险因素.但急性扁桃体炎并不是分泌性中耳炎的危险因素,另外发现母乳喂养是分泌性中耳炎的保护因素.有急性中耳炎病史且经常鼻塞的儿童应定期进行耳鼻咽喉科体检.     

儿童与成人分泌性中耳炎的临床分析

目的：探讨儿童与成人分泌性中耳炎（SOM）在病因、病程、临床特征和听力学等方面的异同。方法：对42例（74耳）儿童和34例（43耳）成人SOM患者术前临床资料及听力学检查资料进行对比分析。结果：儿童SOM平均病程较成人短,以腺样体肥大多见,成人以中耳乳突炎多见。C型鼓室导抗图的成人患者鼓室负压大于儿童（P〈0．05）。儿童与成人SOM各频率气导听阈均提高,并且都可出现骨导听阈提高,以高频2、4kHz为主,且成人高频4kHz骨导听阈提高较儿童明显（P〈0．05）。结论：儿童病程一般较成人短,以腺样体肥大多见,易引起中耳积液。儿童SOM与成人一样都可以引起感音神经性聋,以高频损害为主,但高频下降没有成人明显,但由于可造成儿童学语与认知方面的不良后果,应及时干预和诊治。

目的探讨经保守治疗无效的儿童分泌性中耳炎患者外科手术干预的方式和效果。方法对96例(118耳)儿童分泌性中耳炎患者在内镜下行腺样体切除加鼓室置管术,部分合并扁桃体肥大的患儿行扁桃体切除术,术后随访半年以上并评价其治疗效果。结果 96例患儿中行鼓室置管术35例,腺样体切除加鼓室置管术49例,腺样体切除加扁桃体切除加鼓室置管术12例;术前平均听阈为(42±5)dB,术后1周为(34±4)dB,与术前比较具有统计学差异(t=12.12,P<0.05);术后1个月为(22±2)dB,与术前比较具有统计学差异(t=15.27,P<0.01);术后听力明显改善,鼻塞、夜间张口呼吸和打鼾症状明显缓解。结论对患有分泌性中耳炎的儿童进行个体化的手术治疗,腺样体切除加鼓室置管术是经保守治疗无效的儿童分泌性中耳炎的基本术式。     

Cytokines in children with otitis media with effusion

We assayed 38 middle ear effusions from 23 children aged 4–13 years (mean 7) undergoing tympanostomy tube placements. All fluid was assayed for tumor necrosis factor (TNF) α, interleukin (IL) 1β, IL-8, and IL-10. Cytokine concentrations were measured by means of an enzyme-linked immunosorbent assay. Detectable levels of IL-1β, IL-8, and IL-10 were found in all of the effusions. TNF-α was detected in 18 of the middle ear effusions (47.4%). The mean concentration of TNF-α, IL-1β, IL-8, and IL-10 was, respectively, 0.423 ± 1.39, 30.58 ± 68.7, 7001.9 ± 6743, and 56 ± 58.7 pg/ml. There was a strong, statistically significant correlation between the concentrations of TNF-α and IL-1β (r = 0.87, P = 0.001) and between IL-1β and IL-8 (r = 0.53, P = 0.001). There was no correlation between the concentrations of IL-10 and other cytokines examined or between tympanic membrane pathology and the concentrations of TNF-α, IL-1β, IL-8, or IL-10. The presence of IL-10 in middle ear effusions may be one of the causes of a lack of clinical features of acute inflammation and may lead to a chronic inflammatory state.

目的：探讨腺样体肥大致儿童分泌性中耳炎的诊治方法和手术效果。方法：对37例患儿行内镜下腺样体切除＋鼓膜置管术。结果：患儿术后听力均提高,拔管后随访13～17个月未见复发。结论：内镜下腺样体切除＋鼓膜置管术对腺样体肥大致儿童分泌性中耳炎有确切疗效。     

儿童分泌性中耳炎的外科手术干预

目的探讨儿童分泌性中耳炎的手术干预方式，为儿童听力筛查中分泌性中耳炎患儿的干预措施选择提供临床资料。方法总结2004-2008年我院90例儿童分泌性中耳炎接受手术治疗且资料完整者45例（82耳）的年龄特点、听力下降时间、手术方式、手术前后听力状况比较。结果术前平均纯音听阈FrrA（pure-tone threshold average，500Hz，1000Hz，2000Hz，4000Hz听阈均值）从8dBHL-61dBHL，平均（34.8&#177;12.09）dBHL。术后PTA从0dB HL-38dB HL，平均（15.9&#177;7.88）dB HL，3耳术后听闯提高，4耳无改善，75耳听阈降低，占91.5％，平均听阈降低18.9dBHL。手术方式：鼓膜置管术9例，腺样体切除＋鼓膜置管术29例，腺样体切除＋扁桃体切除＋鼓膜置管术7例。结论腺样体切除＋鼓膜置管术是我们治疗儿童分泌性中耳炎的基本术式；扁桃体切除术不作为治疗分泌性中耳炎常规选择；对儿童分泌性中耳炎的术式选择应该个体化。     

分泌性中耳炎患者吸鼻试验检测结果分析

目的 观察分析分泌性中耳炎(otitis media with effusion,OME)患者吸鼻试验结果,探讨咽鼓管闭合功能在OME发病中的作用.方法 选择56例成人OME患者、16例儿童OME患者、66例健康成年人和20例健康儿童做为研究对象,对4组人群采用问卷调查及使用咽鼓管功能综合检查仪进行吸鼻试验检测,并对结果进行统计分析.结果 以外耳道压低于基线10 dapa(含10 dapa)定为吸鼻试验阳性.成人OME组吸鼻试验阳性率为64.86％(对照组为9.09％),儿童OME组吸鼻试验阳性率为70.83％(对照组为38.24％),均明显高于对照组(P值均＜0.05),而成人与儿童OME患者吸鼻试验阳性率差异无统计学意义(X2=0.289,P＞0.05).结论 OME患者吸鼻试验阳性率明显高于健康对照组,提示咽鼓管闭合功能不全参与了OME的发病.     

Adenoidectomy for otitis media with effusion in 2-3-year-old children

Objective

To compare the efficacy of three surgical treatment combinations - myringotomy and tympanostomy tube insertion (M&T), adenoidectomy with M&T (A-M&T), and adenoidectomy with myringotomy (A-M) - in reducing middle-ear disease in young children with chronic OME.

Methods

Children 24-47 months of age, with a history of bilateral middle-ear effusion (MEE) for at least 3 months, unilateral for 6 months or longer or unilateral for 3 months after extrusion of a tympanostomy tube, unresponsive to recent antibiotic, were randomly assigned to either M&T, A-M&T, or A-M. Treatment assignment was stratified by age (24-35 months, 36-47 months), nasal obstruction (no, yes) and previous history of M&T (no, yes). Subjects were followed monthly and with any signs or symptoms of ear disease for up to 36 months.

Results

Ninety-eight subjects were randomly assigned to the three treatment groups. Fifty-six subjects (57%) were 24-35 months of age; 63% had nasal obstruction, and 36% had previously undergone M&T. During the 36 months after entry, subjects were noted to have MEE for the following percentages of time: 18.6% in the M&T group, 20.6% in the A-M&T group, and 31.1% in the A-M group (M&T vs. A-M&T, p = 0.87; M&T vs. A-M, p = 0.01). By 36 months, there were no differences in the number of further surgical procedures for ear disease needed among the groups.

Conclusions

Adenoidectomy with or without tube insertion provided no advantage to young children with chronic OME in regard to time with effusion compared to tube insertion alone. Fewer tympanostomy tubes were placed in children undergoing A-M as their initial procedure, but this should be balanced by the performance of the more invasive surgical procedure and their increased time with effusion.     

婴幼儿中耳炎的听力学特征分析

目的 分析婴幼儿中耳炎的听力学特征,探讨多种听力学测试方法在婴幼儿中耳炎的诊断和干预中的作用.方法 收集2004年12月至2007年6月由外院转入本院进行听力学诊断性检查后确诊或高度怀疑中耳炎的56例婴幼儿患者(男加例,女16例).初诊年龄为42 d至3岁,平均为5个月.患儿在完成耳鼻咽喉科常规检查后,进行了多种听力学测试方法联合诊断,包括听性脑干反应(ABR)、耳声发射(OAE)、鼓室声导抗测试(226和1000 Hz探测音),4例患儿完成了小儿行为测听.结果 56例(112耳)中有87耳诊断为中耳炎,31例为双侧,25例为单侧.56例中有49例在出生后3 d内进行了新生儿听力筛查,其中36例初筛未通过;42 d时行进一步筛查的有52例(其中有3例未行初筛直接进行了复筛),显示均为未通过.4例患儿未经过听力筛查,为家长发现听力不佳来诊.52例(104耳)进行了226 Hz鼓室声导抗测试,其中20例(28耳)鼓室图B型或c型;39例(78耳)进行了1000 Hz鼓室声导抗测试,其中38例(55耳)出现异常;56例(112耳)进行了ABR检查,其中49例(74耳)出现ABR的波I潜伏期延长;56例(112耳)进行了OAE测试,其中55例(81耳)未通过;4例(8耳)完成了小儿行为测听,均出现骨、气导差.结论 联合应用226 Hz及1000 Hz鼓室声导抗测试、ABR潜伏期及阈值测试、小儿行为测听、OAE测试多种方法能够发现婴幼儿中耳炎的特征性表现,在早期诊断中具有帮助.     

The natural course of otitis media with effusion in preschool children

Summary In order to gain an insight into the natural course of otitis media with effusion (OME), a prospective study was carried out on 1328 children out of a cohort of 1439 preschool children. These children were seen in follow-up for their OME every 3 months, at which times tympanometry was performed. The results show a fairly constant rate of improvement of about 50% every 3 months. The cumulative rate of recurrence of OME was about 50% in the study period. Two-thirds of all OME with flat tympanograms had a duration of less than 3 months. Some factors could be identified as having an effect on the natural history of OME. The season and patients' age and sex were found to be associated with the duration and the recovery rate. Risk factors for recurrences were the same as those already reported in the literature.     

腺样体切除对儿童分泌性中耳炎听力的影响

目的探讨腺样体切除术对分泌性中耳炎听力的影响。方法对72例确诊为腺样体肥大所致的分泌性中耳炎患儿随机分为非手术组和手术组，分别进行药物治疗和手术治疗。结果非手术组治疗后听阈≤20dB12耳，手术组治疗后听阈≤20dB36耳，两组治疗后听阈改变经x^2检验差异有显著性。结论腺样体切除术对分泌性中耳炎所致的听力下降的改善是非常有效的。     

Histopathology of otitis media with effusion

Summary Ultrastructural studies of the middle ear mucosa appear to be of significant value in better understanding the pathology of otitis media with effusion (OME). Our present study was undertaken in order to take advantage of the use of electron microscopy in investigating all areas of the middle ear mucosa. Tissues studied were obtained from the fresh postmortem temporal bones of three patients with OME and terminal head and neck malignancies. In the mucoid type of effusion (cases 1 and 2), goblet cells were seen to proliferate and secretory activity was greatly enhanced. In contrast, there was no evidence of secretory cell proliferation in the serous type of effusion. It was noteworthy that accumulated fluid was not homogeneous in the same ear, as exemplified by case 1, in which both mucoid and serous effusions were present. This occurrence was possibly the result of topographic diversity involving the secretory activity of the middle ear.Presented at the Extraordinary International Symposium on Recent Advances in Otitis Media with Effusion, Kyoto, Japan, 12–15 January 1985     

Consumer acoustic reflectometry: Accuracy in diagnosis of otitis media with effusion in children

Objective

Acoustic reflectometry is a technique based on a sonar that enables the diagnosis of middle ear effusion. We aimed to evaluate the accuracy and diagnostic value of consumer type acoustic reflectometry device for determining middle ear effusion in children.

Methods

Acoustic reflectometry and tympanometries of 84 children, from 3 to 14 years of age, were done the day before they underwent adenoidectomy/adenotonsillectomy and myringotomy ± ventilation tube insertion under general anesthesia in the operating room with diagnosis of middle ear effusion. Their test results and the results of myringotomies, which is the golden standard technique in determination of otitis media with effusion, were compared. Specificity, sensitivity, positive and negative predictive values of both instruments in detecting middle ear fluid were determined.

Results

Otitis media with effusion was detected in 106 ears (63.1%) during myringotomy. The sensitivity and specificities of acoustic reflectometry were found to be 83.33% and 68.18%, and tympanometry were 84.48% and 84.62%, respectively. The positive predictive value was 75.12% for acoustic reflectometry and 88.56% for tympanometry, and negative predictive values of acoustic reflectometry and tympanometry were 87.66% and 89.2%, respectively. The sensitivity of the AR was comparable to tympanometry (p > 0.01), however the specificity, PPV and NPV of AR were lower than tympanometry (p < 0.001).

Conclusions

Consumer type acoustic reflectometry is highly sensitive, objective and easy to perform technique for detecting otitis media with effusion, and it may help us to diagnose otitis media with effusion in early stages if used by family practitioners or parents.     

儿童腺样体肥大合并慢性鼻窦炎对分泌性中耳炎发生率的影响

目的探讨儿童腺样体肥大(AH)合并慢性鼻窦炎(CRS)对分泌性中耳炎(OME)发生率的影响。方法对我院2017年至2018年行腺样体切除术或腺样体扁桃体切除术的腺样体肥大患者的临床资料进行统计和分析,包括病史和体征,电子鼻咽镜检查,声阻抗测试以评估腺样体肥大患者分泌性中耳炎和慢性鼻窦炎的患病情况。并使用统计软件SPSS 24.0进行统计分析。结果在208例AH儿童中,有分泌性中耳炎的50例(24%),在学龄儿童(6~12岁)腺样体肥大患者中分泌性中耳炎的发生率最高。腺样体肥大组和腺样体肥大合并慢性鼻窦炎组之间分泌性中耳炎的发生率在统计学上有差异(P=0.001)。结论患有慢性鼻窦炎的腺样体肥大儿童患分泌性中耳炎的风险相应增加,而学龄期的腺样体肥大儿童分泌性中耳炎发生率最高。     

儿童分泌性中耳炎致骨导听力下降的临床特征分析

目的 探讨儿童分泌性中耳炎致骨导听力下降的特点、病因和预后.方法 回顾性分析75例(82耳)分泌性中耳炎患儿骨导听力下降的临床资料,并对其发病年龄、病程、积液性质和积液量与骨导听阈的关系进行观察.结果 75例患儿(82耳)骨导听力下降,平均骨导阈值在2.0 kHz和4.0kHz处增高最明显.骨导听阈与病程和积液性质显著相关(P＜0.01或P＜0.05),与年龄、积液量无关.75例患儿均采取鼓膜切开置管术和(或)腺样体切除术,术后给予药物治疗.随访6月,听力恢复正常者76耳,气导听阈下降但骨导听阈无改善者6耳.结论 分泌性中耳炎可导致儿童骨导阈值增高,是导致儿童耳聋的危险因素之一,及早干预可避免病情发展.     

Distortion product otoacoustic emission together with tympanometry for assessing otitis media with effusion in children

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?Conclusions: DPOAE could be a great help in screening for middle ear effusion in patients with a type ‘C’ tympanogram.
