Developmental impairments in children have been attributed to persistent middle-ear effusion in their early years of life. Previously, we reported that among children younger than 3 years of age with persistent middle-ear effusion, prompt as compared with delayed insertion of tympanostomy tubes did not result in improved cognitive, language, speech, or psychosocial development at 3, 4, or 6 years of age. However, other important components of development could not be assessed until the children were older.
We enrolled 6350 infants soon after birth and evaluated them regularly for middle-ear effusion. Before 3 years of age, 429 children with persistent effusion were randomly assigned to undergo the insertion of tympanostomy tubes either promptly or up to 9 months later if effusion persisted. We assessed literacy, attention, social skills, and academic achievement in 391 of these children at 9 to 11 years of age.
Mean (+/-SD) scores on 48 developmental measures in the group of children who were assigned to undergo early insertion of tympanostomy tubes did not differ significantly from the scores in the group that was assigned to undergo delayed insertion. These measures included the Passage Comprehension subtest of the Woodcock Reading Mastery Tests (mean score, 98+/-12 in the early-treatment group and 99+/-12 in the delayed-treatment group); the Spelling, Writing Samples, and Calculation subtests of the Woodcock-Johnson III Tests of Achievement (96+/-13 and 97+/-16; 104+/-14 and 105+/-15; and 99+/-13 and 99+/-13, respectively); and inattention ratings on visual and auditory continuous performance tests.
In otherwise healthy young children who have persistent middle-ear effusion, as defined in our study, prompt insertion of tympanostomy tubes does not improve developmental outcomes up to 9 to 11 years of age. (ClinicalTrials.gov number, NCT00365092 [ClinicalTrials.gov].).
儿童发育障碍被认为与早年持续性中耳积液有关。此前,我们报告称,在3岁以下患有持续性中耳积液的儿童中,与延迟插入鼓膜造孔管相比,早期插入鼓膜造孔管在3岁、4岁或6岁时并未改善认知、语言、言语或心理社会发育。然而,在儿童年龄更大之前,无法评估发育的其他重要组成部分。
我们在出生后不久招募了6350名婴儿,并定期评估他们是否有中耳积液。在3岁之前,429名患有持续性积液的儿童被随机分配,若积液持续存在,要么立即插入鼓膜造孔管,要么在9个月后插入。我们在这些儿童9至11岁时评估了其中391名儿童的读写能力、注意力、社交技能和学业成绩。
被分配早期插入鼓膜造孔管的儿童组在48项发育指标上的平均(±标准差)得分与被分配延迟插入的儿童组得分无显著差异。这些指标包括伍德库克阅读能力测验的段落理解子测验(早期治疗组平均得分98±12,延迟治疗组平均得分99±12);伍德库克-约翰逊III成就测验的拼写、写作样本和计算子测验(分别为96±13和97±16;104±14和105±15;99±13和99±13);以及视觉和听觉持续性操作测验中的注意力不集中评分。
在我们研究定义的其他方面健康的患有持续性中耳积液的幼儿中,早期插入鼓膜造孔管在9至11岁时并不能改善发育结果。(临床试验注册号,NCT00365092 [ClinicalTrials.gov]。)
