A group of 266 children (515 ears), ranging in age from 5 months to 11 years, was studied. These children were candidates for the insertion of ventilation tubes, or adenoidectomy and/or tonsillectomy with myringotomy. Before surgery, tympanometry was performed. The surgical and tympanometric findings were compared afterwards. Two different tympanometers were used (GSI-27A and TYMP-85TT). This study showed a comparable validity of these two tympanometers. The sensitivity and specificity of tympanometry in the age group of 5 months to 2 years did not show a significant difference from that in the age group of 2-12 years. Otoscopy has limited value for the diagnosis of middle ear effusion in this age group.
对一组年龄在5个月至11岁之间的266名儿童（515只耳朵）进行了研究。这些儿童是拟进行通气管插入术、或腺样体切除术和/或扁桃体切除术加鼓膜切开术的患者。手术前进行了鼓室图检查。之后对手术和鼓室图检查结果进行了比较。使用了两种不同的鼓室图仪（GSI - 27A和TYMP - 85TT）。本研究表明这两种鼓室图仪具有相当的有效性。5个月至2岁年龄组鼓室图检查的敏感性和特异性与2 - 12岁年龄组相比无显著差异。耳镜检查在该年龄组中耳积液诊断中的价值有限。
