【摘要】：目的:探討成人錘砧關節(jié)和砧鐙關節(jié)的正常HRCT表現(xiàn)及臨床意義。方法:回顧性分析46例成人的正常錘砧關節(jié)和砧鐙關節(jié)HRCT圖像,對其形態(tài)進行影像學分類;對可能存在的兩側(cè)錘砧關節(jié)或砧鐙關節(jié)形態(tài)不對稱情況進行統(tǒng)計;對錘砧關節(jié)和砧鐙關節(jié)間隙進行影像學測量,利用統(tǒng)計學軟件計算得到一組正常值范圍。結(jié)果:錘砧關節(jié)HRCT表現(xiàn)為3種形態(tài):均勻的弧形(77耳,83.7%)、鋸齒樣(9耳,9.8%)和喇叭口樣(6耳,6.5%);砧鐙關節(jié)形態(tài)為2種:直接連接(31耳,33.7%)和間接連接(61耳,66.3%)。46例受檢者中,兩側(cè)錘砧關節(jié)形態(tài)不對稱5例(10.9%);砧鐙關節(jié)形態(tài)不對稱3例(6.5%)。對橫斷面上的錘砧關節(jié)和鐙骨斜位上的砧鐙關節(jié)間隙的測量結(jié)果分別為(0.45±0.10)mm和(0.43±0.12)mm。結(jié)論:錘砧關節(jié)和砧鐙關節(jié)的正常HRCT表現(xiàn)可為特殊情況下診斷錘砧關節(jié)和砧鐙關節(jié)脫位提供較為客觀的參考依據(jù)。
[Abstract]:Objective: to investigate the normal HRCT features and clinical significance of the hammer-anvil joint and stirrup joint in adults. Methods: the HRCT images of 46 adults with normal hammer-anvil joint and incudral joint were analyzed retrospectively. Their morphology was classified by imaging. The asymmetry of the shape of the hammerstock or stirrup joint on both sides was analyzed. A group of normal values were calculated by using statistical software. Results: the HRCT of hammer-anvil joint showed three types: uniform arcuate shape and 77 ears. 83.7% of the ears, 9 ears with serrated teeth, 9 ears with 9 ears, and 6 ears with trumpets. The shape of stirrup joint was divided into two types: direct connection with 31 ears and 33. 7%) and indirect connection with 61 ears of 61 ears. The anvil joints of both sides were dissymmetrical in shape in 5 cases. The results of the measurement of the space between the anvil joint on the cross section and on the oblique position of the stapes were 0.45 鹵0.10mm and 0.10mm, respectively. Conclusion: the normal HRCT findings of the anvil joint and the stirrup joint can provide an objective reference for the diagnosis of the dislocation of the anvil joint and the stirrup joint under special circumstances.

【正文快照】： 聽骨鏈損傷是顱腦損傷的常見并發(fā)癥,但其引起的聽力下降在傷后早期往往沒有引起臨床上的足夠重視。這是因為傷后早期所關注的重點多為顱腦損傷或其他較嚴重的合并傷;并且錘砧關節(jié)位于上鼓室,常規(guī)的鼓室探查難以發(fā)現(xiàn)其病變。此時對聽骨鏈損傷的診斷只能依靠影像學手段。明顯的
