目的:探讨分析声导抗检查是否应作为鼾症儿童术前检查的必要辅助检查。方法:收集安徽医科大学第一附属医院南区自开院,即2023年12月26日至2024年11月期间266例住院鼾症儿童资料,统计其中完成影像学检查如耳纤维内镜、鼻咽侧位片等及声导抗检查结果,分别分析鼾症患儿并发SOM的可能性与下颌升支高度与总前面部高度的比值(Ar-Go/N-Me, A/N)、患儿年龄的相关性,及不同性别的患病有无差异。讨论鼾症儿童术前检查项目中,声导抗检查是否应作为鼾症儿童术前常规必要检查项目。结论:1. 鼾症患儿并发SOM的概率和患病侧别数量与A/N数值正相关。2. 鼾症患儿是否并发SOM、并发SOM的患耳数量均与性别无明显差异性。3. 当年龄越大时,鼾症患儿并发SOM的概率降低,并发患耳的数量降低。Objective: To investigate whether acoustic immittance should be used as a necessary auxiliary examination in the preoperative examination of children with snoring. Methods: Data of 266 hospitalized children with snoring in the First Affiliated Hospital of Anhui Medical University from December 26, 2023 to November 2024 were collected. The results of imaging examinations such as otofiberscopy, lateral view of nasopharynx, and acoustic impedance were analyzed. The relationships between SOM and Ar-Go/N-Me (A/N) ratio, age, and gender were analyzed. We discuss whether acoustic impedance testing should be included as a routine and necessary preoperative examination for snoring children. Conclusion: (1) The probability of SOM and the number of affected sides in children with snoring are positively correlated with A/N value. (2) There was no significant difference in the incidence of SOM and the number of affected ears with SOM between male and female children. (3) As the age increased, the probability of SOM and the number of complicated ears decreased.
目的研究正常婴儿短声骨导听性脑干反应(bone conduction click auditory brainstem responeses,BC-ABR)的阈值、潜伏期及其与气导听性脑干反应(air conduction click auditory brainstem responeses,AC-ABR)的关系,为BC-ABR在婴儿听力评估中的应用提供参考依据。方法将20例听力正常婴儿按月龄分为两组:A组婴儿<6月,共10例20耳;B组婴儿≥6月,共10例20耳。分别进行短声AC、BC-ABR测试,对测试结果进行统计分析。结果 1BC-ABR波形与AC-ABR波形相似,BC-ABR波V潜伏期为7.45±0.35ms,反应阈为7.50±4.24d B n HL,反应阈的第95百分位数为15.00d B nHL。2不同性别、不同耳别间BC-ABR波V阈值和潜伏期差异均无统计学意义(P>0.05)。3A组、B组BC-ABR波V潜伏期分别为7.48±0.37ms和7.42±0.34ms,差异无统计学意义(P>0.05);波V阈值分别为8.00±4.70d B nHL和7.00±3.77d B nHL,差异无统计学意义(P>0.05);AC、BC-ABR阈值的差值分别为9.75±4.44d B nHL和9.25±2.94d B nHL,差异无统计学意义(P=0.68)。4AC-ABR波V阈值为17.00±2.95d B nHL,明显高于BC-ABR波V阈值,差异有统计学意义(P<0.05);AC-ABR与BC-ABR阈值的差值为9.50±3.72d B n HL,第95百分位数为15.00d Bn HL。结论 BC-ABR波形特点与AC-ABR极为相似;婴儿BC-ABR阈值的正常值可采用统一的参考标准;本研究为婴儿听力的早期评估和干预提供了可靠依据。
目的探讨先天性外耳畸形婴儿的听力水平及特点。方法选取34例(41耳)先天性外耳畸形婴儿为观察组,另选取20例(40耳)健听婴儿为对照组,分别测试并统计两组婴儿的气导听性脑干反应(air-conductionauditorybrainstem response,AC-ABR)潜伏期和阈值,并对结果进行统计分析。结果观察组中97.56%(40/41)的畸形耳为中、重度听力损失;畸形耳AC-ABR阈值与耳廓畸形分级之间呈正相关(r=0.670,P<0.01);畸形耳AC-ABR阈值(75.37±8.97 dB nHL)较对照耳(17.5±7.07dBnHL)显著升高(P<0.01);畸形耳Ⅴ波潜伏期(7.61±0.63ms)较对照耳(6.20±0.2ms)显著延长(P<0.01)。结论先天性外耳畸形婴儿伴发听力损失以中、重度居多,存在外耳畸形应尽早诊断并干预。
