To compare Ostmann's fat pad (OFP) size between healthy ears and ears with chronic otitis media with cholesteatoma (COMwC) in children, to assess its role in the disease.
MRI scans of 29 children with unilateral COMwC with conductive hearing loss were used to measure OFP, represented by the maximal 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 were compared between the healthy and pathological ear in each patient.
No difference in OFP size was observed between healthy (H) ears (mean M1H:M2H ratio 0.72 ± 2.28) compared to ears with COMwC pathology (P) (mean M1P:M2P ratio .68 ± 1.57; P = .943) in children, suggesting that OFP size abnormalities do not have a role in pediatric COMwC.
OFP size was not correlated to the development of unilateral COMwC in children.
比较儿童慢性中耳炎伴胆脂瘤（COMwC）患者与健康耳之间 Ostmann 脂肪垫（OFP）的大小，评估其在疾病中的作用。
使用 29 例单侧 COMwC 伴传导性听力损失儿童的 MRI 扫描来测量 OFP，用腭帆张肌（TVP）内侧高强度区域的最大直径表示：M1。从 OFP 的内侧边界到翼内肌的内侧边界定义参考直径：M2。在每位患者中比较健康耳和病变耳的 M1、M2 及 M1：M2 比值。
与 COMwC 病理耳（M1P：M2P 比值为 0.68 ± 1.57，P = 0.943）相比，儿童健康耳（M1H：M2H 比值为 0.72 ± 2.28）的 OFP 大小无差异，表明 OFP 大小异常与儿童 COMwC 的发生无关。
OFP 大小与儿童单侧 COMwC 的发展无关。
