To compare the size of Ostmann's fat pad (OFP) between healthy ears and ears with chronic otitis media with cholestatoma (COMwC) using magnetic resonance imaging (MRI).
Twenty-six patients with unilateral COMwC underwent mastoidectomy. Pre-operative MRI records were reviewed retrospectively. The healthy ears served as the control group. OFP is represented by the maximum diameter of the high intensity area medial to the tensor veli palatini muscle (TVP); M1. A reference diameter was defined from the medial border of OFP reaching the medial border of the medial pterygoid muscle; M2. Values of M1, M2 and the ratio of M1:M2 was compared between the healthy and pathological ear in each patient.
All 26 patients (16 females,10 males) had unilateral cholestatoma. Mean age was 37.6 years (range 19-83). In the healthy () ears group, mean M1 was 2.04 ± 0.53 mm, mean M2 was 9.57 ± 2.57 mm.In the pathological () ears group; mean M1 was 2.03 ± 0.55 mm, mean M2 was 9.86 ± 2.37 mm. A comparison of M1 and M2 values between the healthy and pathological ear groups was not statistically significant ( = .853 and = .509, respectively).Mean M1:M2 ratio in the healthy ears group was 0.22 ± 0.05, mean M1:M2 ratio in the pathological ear group was 0.21 ± 0.06. A comparison between these ratios found no significant statistical correlation ( = .607).
The size of Ostmann's fat pad does not affect the development of chronic otitis media with cholestatoma in adults.
通过磁共振成像（MRI）比较健康耳和伴有胆脂瘤型慢性中耳炎（COMwC）的耳中海斯曼氏脂肪垫（OFP）的大小。
26 例单侧 COMwC 患者接受乳突切除术。回顾性分析术前 MRI 记录。健康耳作为对照组。OFP 用腭帆张肌（TVP）内侧高信号区域的最大直径表示（M1）；定义一个参考直径，即从 OFP 的内侧边界到达翼内肌的内侧边界（M2）；比较每位患者患耳和健耳的 M1、M2 值以及 M1：M2 比值。
所有 26 例患者（16 例女性，10 例男性）均为单侧胆脂瘤。平均年龄为 37.6 岁（19-83 岁）。在健康（）耳组中，M1 的平均值为 2.04 ± 0.53mm，M2 的平均值为 9.57 ± 2.57mm；在病变（）耳组中，M1 的平均值为 2.03 ± 0.55mm，M2 的平均值为 9.86 ± 2.37mm。M1 和 M2 值在健耳组和病耳组之间的比较无统计学意义（=0.853 和=0.509）。健耳组 M1：M2 比值的平均值为 0.22 ± 0.05，病耳组 M1：M2 比值的平均值为 0.21 ± 0.06。这两个比值之间的比较没有显著的统计学相关性（=0.607）。
海斯曼氏脂肪垫的大小不会影响成人胆脂瘤型慢性中耳炎的发展。
