With early diagnosis and prompt surgical intervention, the sphenoid sinus mucocele-associated neurological deficits can be restored completely. Purpose: Here we examine a case of sphenoid sinus mucocele presenting with left abducens nerve palsy and subsequent loss of left eye vision. 惟有早期诊断及手术治疗,其所导致的外展神经麻痹及视力丧失才有可能完全恢复。目的:报告一例因罹患蝶窦黏液囊肿而导致单侧外展神经麻痹及视力丧失的病例。

Results: The most affected nerves in diabetic ophthalmoplegia were abducens nerve and oculomotor nerve, usually not completely paralyzed and with 100~ 200 degree strabismus. 结果:糖尿病性眼肌麻痹受累的脑神经多以外展神经、动眼神经为主;麻痹程度多呈不完全性或者100~200°斜视;
Triangle of abducens nerve was formed by the petrosphenoidal ligament, the medial wall of Meckel's cave and the posterolateral wall of ICA, and abducens nerve passed through this triangle. 由岩蝶韧带、三叉神经囊内侧面及ICA后外侧面围成,展神经动脉后段经过此三角;
Objective: To provide applied anatomical data of abducens nerve for the skull base surgery. 目的:为颅底外科提供展神经的显微解剖学资料。
Paralysis of oculomotor nerve accounted for 36.28% of the primary affected region. Paralysis of abducens nerve accounted for 30.09%. 受累部位以动眼神经麻痹占首位为36.28%外展神经麻痹次之,占30.09%。
Anatomic study on intracranial portion of abducens nerve and its clinical significance 展神经颅内段的分段毗邻与转角及其临床意义
Conclusions In atypical cases, the retraction of the globe in adduction was not obvious and the diagnosis of DRS must be differentiated from the following ocular motility disorders, namely, abducens nerve palsy, Mebius syndrome, congenital oculomotor apraxia and congenital or infantile esotropia. 结论非典型患者内转时,眼球后退不明显,诊断DRS时应与眼球运动异常疾病即外展神经麻痹、Moebius综合征、先天性眼球运动不能和先天性或婴儿型内斜视相鉴别。
HRP labeled neurons in the MTN extended from the pons at the level of the nucleus of the abducens nerve to the midbrain at the rostral level of the superior colliculus. 在三叉神经中脑核内HRP标记神经原的分布范围自脑桥的外展神经核水平开始向上延伸至中脑上丘嘴侧水平。
Conclusions: Abducens nerve is easy to be injured for the forming of three different angulations during its courses, and its complicated anatomic relationship with blood vessel, nerves, ligaments and bones. 结论:①展神经行程中的3个转角,以及与血管、神经、韧带、骨等复杂的解剖关系,使其脆弱而易于损伤;
Abducens nerve was the medial limit of drilling petrous bone; 外展神经是磨除颞骨岩部的内限;
Abducens nerve exhibited three different angulations during its course from the external side of brainstem to the superior orbital fissure, located at the dural entrance porus, the petrous apex and the lateral wall of the cavernous segment of ICA respectively. 展神经颅内段在行程中形成3个转角,分别位于脑膜入口处、岩尖及颈内动脉(ICA)的外侧面;
· METHODS: After evisceration, the abducens oculi muscle and the optic nerve were cut, and the hydroxyapatite sphere was implanted primarily in the muscular pyramid. 方法:眼内容物剜出术后,剪断外直肌和视神经,一期植入羟基磷灰石义眼座于肌锥内。
Abducens nerve intimately related with the medial artery of clivus, the lateral artery of clivus, the tentorial marginal artery, the inferior hypophyseal artery and the anterolateral branch of its inferolateral trunk. 斜坡内动脉、斜坡外动脉、小脑幕动脉、垂体下动脉及下干的前外侧支与展神经关系密切;
This approach better reveals the contralateral cavernous sinus and reach the abducens nerve, oculomotor nerve and the superior orbital fissure outside contralateral internal carotid artery. 4. 该入路对对侧的海绵窦显露得更好,可达到对侧颈内动脉外侧的外展神经、动眼神经和眶上裂。
