On certain occasions it becomes important to evaluate vestibular function in a patient with otitis media. The potential application of the air caloric test in evaluating such patients was examined. Patients with unilateral otitis media before and after surgery were studied to answer certain clinical questions. More questions were raised than answers provided. The preliminary conclusions from this study are: 1. Patients with tympanostomy tubes or small perforation of one ear may show a caloric response in the perforated ear equal to that of the intact ear. 2. Patients with a large tympanic membrane perforation on one side may show hyperactive caloric responses on the perforated side. 3. Patients with a moist ear may show inverted horizontal nystagmus to warm air caloric testing. This applies to patients with a large perforation or mastoidectomy cavity. 4. Patients with a dry open mastoid or fenestration cavity are likely to show a hyperactive caloric response on the side of previous surgery, accompanied by vegetative symptoms. This size of the cavity appears to be less important than the presence of the cavity per se. 5. Patients may be safely tested in the early postoperative period.
在某些情况下，评估中耳炎患者的前庭功能变得很重要。研究了空气冷热试验在评估此类患者中的潜在应用。对单侧中耳炎手术前后的患者进行了研究，以回答某些临床问题。提出的问题比给出的答案更多。这项研究的初步结论是：1. 有鼓膜造孔管或单耳小穿孔的患者，穿孔耳的冷热反应可能与正常耳相同。2. 一侧鼓膜大穿孔的患者，穿孔侧的冷热反应可能亢进。3. 耳内潮湿的患者，对温热空气冷热试验可能出现反向水平眼震。这适用于有大穿孔或乳突切除腔的患者。4. 干性开放乳突或开窗腔的患者，既往手术侧可能出现冷热反应亢进，并伴有自主神经症状。腔的大小似乎不如腔本身的存在重要。5. 患者在术后早期可安全地进行测试。
