  • The abducens nerve (AN; cranial nerve VI) exits the brainstem at the inferior pontine sulcus, pierces the dura of the posterior cranial fossa, passes through the cavernous sinus in close contact to the internal carotid artery (ICA) and traverses the superior orbital fissure to reach the orbit to innervate the lateral rectus muscle. At its exit from the brainstem, the AN includes only axons from lower motor neurons in the abducens nucleus. However, as the AN crosses the ICA it receives a number of branches from the internal carotid sympathetic plexus. The arrangement, neurochemical profile and function of these sympathetic axons running along the AN remain unresolved. Herein, we use gross dissection and microscopic study of hematoxylin and eosin-stained sections and sections with tyrosine hydroxylase immunolabeling. Our results suggest the AN receives multiple bundles of unmyelinated axons that use norepinephrine as a neurotransmitter consistent with postganglionic sympathetic axons.

  • Diplopia is a rare complication of spine surgery. The abducens nerve is one of the cranial nerves most commonly related to diplopia caused by traction injury. We report a case of a 71-year-old woman who presented with diplopia developing from abducens nerve palsy after C1-C2 fixation and fusion due to atlantoaxial subluxation with cord compression. As soon as we discovered the symptoms, we suspected excessive traction by the instrument and subsequently performed reoperation. Subsequently, the patient's symptoms improved. In other reported cases we reviewed, most were transient. However, we thought that our rapid response also helped the patient's fast recovery in this case. The mechanisms by which postoperative diplopia develops vary and, thus, remain unclear. We should pay attention to the fact that the condition is sometimes an indicator of an underlying, life-threatening condition. Therefore, all patients with postoperative diplopia should undergo thorough ophthalmological and neurological evaluations as well as careful observation by a multidisciplinary team.

  • Intracranial hypotension is characterized by a postural headache which is relieved in a supine position and worsened in a sitting or standing position. Although less commonly reported than postural headache, sixth nerve palsy has also been observed in intracranial hypotension. The epidural blood patch (EBP) has been performed for postdural puncture headache, but little is known about the proper timing of EBP in the treatment of sixth nerve palsy due to intracranial hypotension. This article reports a case of sixth nerve palsy due to spontaneous intracranial hypotension which was treated by EBP 10 days after the onset of palsy.

  • ■ Objective This is a case report about monocular abducens nerve palsy in a patient with pontine infarction. ■ Method At the time of onset, the patient had eye movement impairment in right eye and diplopia. Brain MRI image showed that there was an infarction in the right pons where the nucleus of abducens nerve is located. There was no obvious improvement in the eye movement before he received Korean medicine treatment. He recieved Korean medicine including acupuncture, electroacupuncture, pharmacoacupuncture and herb medicines for fifty three days. ■ Result After treatment, the movement of right eye was improved to a normal range. The difference in distance from 'center of the pupil' to 'external canthus of the eye' at maximum abducent in both eye changed 0.9cm to 0.1cm at the discharge. In addition, Diplopia was improved at the discharge. ■ Conclusion This case report demonstrated that the Korean medicine treatment is effective to diplopia and eye movement impairment from abducens nerve palsy caused by pontine infarction.

  • Objective : Around the sellar area, there are many important structures. But, the optimal radiation dosage for minimal toxicity to surrounding neural tissue has not been firmly established. The purpose of this study is to evaluate the radiosurgical outcome of juxtasellar tumors and to investigate the relationship between radiation dosage and toxicity to neural tissue. Method : Between May 1992 and June 2000, we treated 65 juxtasellar tumors by using the Leksell Gamma Knife. Among them, 52 patients who could be followed more than 1 year were included in this study. The radiosurgical dosage to the optic pathway, cavernous sinus, Meckel's cave, hypothalamus, pituitary gland and stalk, and brain stem was analyzed and correlated with clinical outcome. The mean follow-up period was 33.5 months(range 12.2- 99.0 months). Result : The clinical response rate was 69.2%. The volume response rate was 61.0% and the radiologic control rate was 92.7%. There were 4 complications(7.7%) of 2 trigeminal neuropathy, 1 abducens nerve palsy, and 1 trigeminal and transient abducens nerve palsy. The optic apparatus appeared to tolerate doses greater than 10Gy. The risk of cranial nerve complications in cavernous sinus seemed to be related to doses of more than 16Gy. In 3 of 4 patients who received more than 16Gy to cavernous sinus, the abducens or trigeminal neuropathy occurred. Also, one patient who received more than 15Gy to the Meckel's cave, trigeminal neuropathy developed. The hypothalamus, pituitary gland and stalk, and brain stem were relatively tolerable to radiation. Conclusion : Gamma Knife radiosurgery seems to be an effective method to control the growth of juxtasellar tumors. To avoid injury to surrounding important neural tissue, careful dose planning and further study for radiation toxicity to neural tissue were needed.

  • Objectives: This research aimed to confirm the efficacy of oriental medicine in sixth cranial nerve palsy and to evaluate the quality of the studies. Methods: Using the medical subject heading (MeSH) keywords "abducens nerve palsy", "abducens nerve paralysis", "sixth nerve palsy", "herbal medicine", "Chinese medicine", "oriental medicine" and "acupuncture", we collected the research papers through an electronic database search in Oriental Medicine Advanced Searching Integrated System (OASIS), National Discovery for Science Leaders (NDSL), PubMed, Cochran Library, and China National Knowledge Infrastructure (CNKI). Results: A total of 136 papers were searched from the databases. Among these, 15 case reports and 8 randomized controlled trials (RCTs) met our criteria. 17 articles were found on the use of acupuncture as the main intervention, 11 on the use of herbal medicine as the main intervention, and 9 on the use of electroacupuncture as the main intervention. The frequently used acupoints were LI4, EX-HN5, GB1, BL2, TE23, LR3, BL1, ST2, GB20, and ST36. All 23 studies confirmed the efficacy of Korean medicine. According to the assessment using the risk of bias, the overall quality of the RCTs was low. Conclusions: Twenty-three papers suggested that Korean medicine treatment for abducens nerve palsy was effective in many cases. Analyzing the potential bias was difficult.
