目的 分析以搏动性耳鸣为主要症状的乙状窦沟骨板缺损的CT特征.方法 回顾性分析首都医科大学附属北京同仁医院2009-2012年11例乙状窦沟骨板缺损引起持续性单侧搏动性耳鸣患者的头颈部双期增强CT表现.结果 CT显示乙状窦沟骨板缺损均位于耳鸣侧.术中和CT均能显示乙状窦沟骨板缺损共13个,位于乙状窦降部8个,乙状窦上曲3个,同时累及乙状窦上曲、降部2个,CT测量骨板缺损的最大左右径[(6.1±3.5)mm]和上下径[(4.2±1.9) mm]均明显大于术中测量的长径[(4.5±3.9)mm]和短径[(3.0±1.3) mm].CT显示而术中未发现骨板缺损5个.9例患者脑静脉回流呈不均衡型,骨板缺损均位于静脉回流优势侧.2例脑静脉同流呈均衡型,骨板缺损均位于左侧.患者耳鸣侧颞骨均气化良好,颞骨气房及鼓室均富含气体.结论 乙状窦沟骨板缺损多位于乙状窦上曲、降部前/外侧壁,好发于脑回流静脉优势及颞骨蜂房气化侧.
目的 分析以搏動性耳鳴為主要癥狀的乙狀竇溝骨闆缺損的CT特徵.方法 迴顧性分析首都醫科大學附屬北京同仁醫院2009-2012年11例乙狀竇溝骨闆缺損引起持續性單側搏動性耳鳴患者的頭頸部雙期增彊CT錶現.結果 CT顯示乙狀竇溝骨闆缺損均位于耳鳴側.術中和CT均能顯示乙狀竇溝骨闆缺損共13箇,位于乙狀竇降部8箇,乙狀竇上麯3箇,同時纍及乙狀竇上麯、降部2箇,CT測量骨闆缺損的最大左右徑[(6.1±3.5)mm]和上下徑[(4.2±1.9) mm]均明顯大于術中測量的長徑[(4.5±3.9)mm]和短徑[(3.0±1.3) mm].CT顯示而術中未髮現骨闆缺損5箇.9例患者腦靜脈迴流呈不均衡型,骨闆缺損均位于靜脈迴流優勢側.2例腦靜脈同流呈均衡型,骨闆缺損均位于左側.患者耳鳴側顳骨均氣化良好,顳骨氣房及鼓室均富含氣體.結論 乙狀竇溝骨闆缺損多位于乙狀竇上麯、降部前/外側壁,好髮于腦迴流靜脈優勢及顳骨蜂房氣化側.

Objective To evaluate the CT the characteristics of dehiscent sigmoid plate accompanied with pulsatile tinnitus (PT).Methods Dual phase contrast enhancement CT data of 15 PT patients were analyzed retrospectively.Results Dehiscent sigmoid plate was located on the same side of PT in all patients.Thirteen defects had been showed in both CT images and surgery.Among of them,eight defects located on the descending segment,3 on the superior curve,and the other 2 defects involved the superior curve and descending segment of sigmoid sinus simultaneously.The maximum anteroposterior and vertical diameters of defect measured in CT images were significant larger than that measured during surgery.There were still 5 defects showed in CT images,which did not been found during surgery.Among 9 patients with unilateral dominant brain venous systems,all the dehiscent sigmoid plates were seen on the dominant side.The other 2 patients showed co-dominant brain venous systems,whose the dehiscent sigmoid plates were on the left side.In addition,extensive pneumatized temporal bone filled with air was found in all patients.Conclusion Dehiscent sigmoid plate co mmonly located on the anterior,lateral,or anterolateral wall of the superior curve or descending segment of the sigmoid plate,which usually coexist with the strong unilateral dominant brain venous system and extensive temporal bone pneumatization.
