CT报告(中英作品展示)

颞骨三维CT

影像所见:

1.       左侧外耳道骨性闭锁,骨性闭锁板厚度约0.89cm。乳突呈气化型,鼓室腔形态可;听小骨畸形,砧镫关节角度增大。耳蜗、前庭、半规管未见异常改变。面神经管乳突段略前移。

2.       右侧外耳道狭窄,各壁骨质未见异常改变。鼓膜不厚。乳突呈气化型;乳突窦及鼓室内未见异常密度影。听小骨形态异常,砧镫关节角度增大。耳蜗、前庭、半规管未见异常改变。面神经管乳突段略前移。

3.       双侧内耳道未见明显增宽或狭窄。

4.       右侧颈静脉窝高位,双侧乙状窦、颅中窝位置未见异常。双侧前庭水管未见扩大。

印象:

1.       左侧骨性外耳道闭锁,听小骨畸形,面神经管乳突段略前移

2.       右侧外耳道狭窄,听小骨形态异常,面神经管乳突段略前移

3.       右侧颈静脉窝高位

 

3D CT of Temporal Bone

Findings:

1.     Left-sided external auditory canal bony atresia, the bony atretic plate was about 0.89cm in thickness. The mastoid showed pneumatization, the tympanic cavity was reasonably normal in morphology; malformation of auditory ossicle, increased angle of incudostapedial joint. No abnormal change of the cochlea, vestibule or semicircular canal. Slight forward shift of mastoid segment of facial nerve canal.

2.     Right-sided external auditory canal stenosis, without abnormal bone change of the wall. The tympanic membrane was not thick. The mastoid showed pneumatization; no opacity of abnormal density in mastoid sinus or tympanic cavity. Abnormal morphology of auditory ossicle. Increased angle of incudostapedial joint. No abnormal change of the cochlea, vestibule or semicircular canal. Slight forward shift of mastoid segment of facial nerve canal.

3.     No evident widening or stenosis of bilateral internal acoustic meatus.

4.     Right-sided high riding jugular fossa. No abnormality of bilateral sigmoid sinuses or middle cranial fossae. No enlargement of bilateral vestibular aqueducts.

Impression:

1.     Left-sided external auditory canal bony atresia, malformation of auditory ossicle, slight forward shift of mastoid segment of facial nerve canal.

2.     Right-sided external auditory canal stenosis, abnormal morphology of auditory ossicle, slight forward shift of mastoid segment of facial nerve canal.

3.     Right-sided high riding jugular fossa.
