A case of a peroneal nerve palsy caused by repeatedly recurred intraneural ganglion cyst is presented. A 19 year old male suffered from tingling sensation on the foot dorsum more than one year and underwent two times of mass excision and nerve palsy was recorvered. But it was recurred once more after 10 months after the second excision. The mass was located in the fibro-osseous tunnel against the fibular neck and the origin of the peroneus longus. The third complete excision was done and full recovery was obtained in 6 months.

Cranial-nerve disorders can be caused by a wide spectrum of diseases, including congenital, inflammatory, and tumorous diseases, and are often encountered in practice. However, the imaging of cranial-nerve disorders is challenging, and understanding the anatomical differences of each region is essential for conducting the best protocols and for detecting subtle changes in cranial nerves during magnetic resonance imaging (MRI) examinations. In this review we discuss which MRI techniques are best for observing normal and pathologic appearance, according to the different regions of the cranial nerves.

When peripheral axons are damaged, neuronal injury signaling pathways induce transcriptional changes that support axon regeneration and consequent functional recovery. The recent development of bioinformatics techniques has allowed for the identification of many of the regeneration-associated genes that are regulated by neural injury, yet it remains unclear how global changes in transcriptome are coordinated. In this article, we review recent studies on the epigenetic mechanisms orchestrating changes in gene expression in response to nerve injury. We highlight the importance of epigenetic mechanisms in discriminating efficient axon regeneration in the peripheral nervous system and very limited axon regrowth in the central nervous system and discuss the therapeutic potential of targeting epigenetic regulators to improve neural recovery.

Background: Distal biceps tendon repairs are commonly performed using open techniques. A minimally invasive distal biceps tendon repair technique using a speculum and hooded endoscope was developed to improve visualization, reduce soft-tissue dissection, and minimize complications. This paper describes the technique and reports the outcomes of 75 minimally invasive distal biceps tendon repairs. Methods: The operation reports and outcomes of 75 patients who underwent distal biceps tendon repair using this technique between 2011 and 2021 were retrospectively reviewed. Results: Median time to follow-up was 12 months (interquartile range [IQR], 6-56 months). Primary outcomes were function as measured by the Disabilities of Arm, Shoulder and Hand Score (DASH) questionnaire, and rate of complications. Median DASH score was 1.7 of 100 (IQR, 0-6.8). There were 2 of 75 (2.7%) re-ruptures of the distal tendon. There were no cases of vascular injury, proximal radius fracture, or posterior interosseous nerve, median, or ulnar nerve palsy. Conclusions: In this series, minimally invasive distal biceps repair was safe and effective with a low rate of major complications. Recovery of function, as indicated by low DASH scores, was satisfactory, and inconvenience during recovery was minimized. Level of evidence: IV.

관절 관절경으로 수술적 치료를 시행한 후 전방 및 후방 골간 신경 증후군이 동시에 발생한 1예를 보고하고자 한다. 45세 남자 환자가 좌측 견관절의 불안정성으로 견관절 관절경 수술을 시행받았다. 전신 마취하 우측 측와위 자세에서 전완부를 신전한 상태에서 견인 장치를 부착한 상태로 2시간 동안 수술을 시행하였다. 1주일 후 환자는 좌측 전완부 동통, 수지의 신전력 및 무지와 인지의 심수지 굴근력의 저하로 외래를 방문하였다. 경과 관찰하였으나 증상이 지속되어 전방 골간 신경에 대해서는 신경 탐색술을 시행하였고 후방 골간 신경에서는 모래 시계 모양의 협착 소견이 발견되어 병변 절제 후 신경 외막 봉합술을 시행하였다. 수술 후 약 5개월간 외래에서 경과 관찰하였다. 신경 탐색술을 시행하고 3개월 후 총수지 신근의 기능이 회복하기 시작하였으며, 점차 회복하여 신경 탐색술 후 5개월째 증상이 완전히 회복되었다. 견관절 관절경 수술 후 전방 및 후방 골간 신경 증후군의 발생은 드물지만 견인 장치 및 수술 중 자세에 의해 유발될 수 있다. 따라서 견인 장치 부착 및 수술 자세에 대해 술자의 주의가 필요하다고 생각한다.

Purpose: The inferior alveolar nerve (IAN) can be damaged as a result of minor oral surgical procedure such as third molar extraction or implant placement. Repair of the injured IAN involves difficulty of access, and research studies are limited to elucidating the process of regeneration by surgical methods. This study sought to establish the rabbit animal model to apply polymeric membrane functionalized with nerve growth factor after a crush lesion for the evaluation of nerve regeneration using the electrophysiologic method. Materials and Methods: The IAN of 2 adult male New Zealand white rabbits (4 nerves) were exposed bilaterally, and crush injury rendered by jeweler's forceps was applied. Nerve conduction velocity was examined electrophysiologically using electromyography before, after, and 4 weeks after the crush injury. To evaluate the regeneration, the pattern of action potential of IAN was recorded, and the characteristics of neurons were histologically observed. Result: After the crush injury, afferent activity decreased in the injured group. Electromyography could not be recorded after four weeks because tissues surrounding the injured nerve collapsed. Decrease in the mean number of axons was observed in the injured part with membrane. Conclusion: Despite the limited result, the present animal model study may provide a possible way to research on the methods of enhancing the recovery of nerve injuries in clinical situations. For clinically widespread acceptance, however, it should gain more consecutive and scientific evidences.

Background and Objetive : Lack of uniformity in reporting facial nerve recovery in patients with facial nerve paralysis has been a major disadvantage in comparing treatment modalities. The objective evaluation of facial nerve function is a complex procedure. The House and Brackmann grading system, the Yanagihara grading system has been recommend as a universal standard for assessing the degree of facial nerve palsy. However, clinical studies for treatment of facial palsy have rarely used this universal standard in oriental medicine. That is the reason for analysing this facial nerve grading system. Material and Method : We choose 10 scales reported from 1955 till 1995. These facial nerve grading systems may be classified as Gross system, Regional system and Specific system. Result and Conculsion : The scales of Botmann and Jonkees, May, Peitersen, and House and Brackmann are the gross facial nerve grading systems with which we grossly assess the facial motor dysfunction and the secondary defect. Among these scales, H-B scale is the most widespred The scales of Yanagihara(若杉文吉), Smith, Adour and Swanson, Jassen, FEMA are the regional facial nerve grading system in which we weight, or unweight the facial motor dysfunction and the secondary defect. For example, the scales of Yanagihara(若杉文吉) and Smith are the unweighted regional scale, the scale of Adour and Swanson, Jassen, FEMA are the weighted regional grading system. The scale of Stennert is the Specific facial nerve grading system in which we respectively assess the grade of facial dysfunction at rest, in motion and the secondary defect. For the objective evaluation of the oriental medicine treatment for facial palsy, we must use the universal standard scale, i.e. the H-B scale, the Yanagihara scale.

Pituitary apoplexy is a clinical syndrome caused by an acute ischemic or hemorrhagic vascular accident involving a pituitary adenoma or an adjacent pituitary gland. Pituitary apoplexy may be associated with a variety of neurological and endocrinological signs and symptoms. However, isolated third cranial nerve palsy with ptosis as the presenting sign of pituitary apoplexy is very rare. We describe two cases of pituitary apoplexy presenting as sudden-onset unilateral ptosis and diplopia. In one case, brain magnetic resonance imaging (MRI) revealed a mass in the pituitary fossa with signs of hemorrhage, upward displacement of the optic chiasm, erosion of the sellar floor and invasion of the right cavernous sinus. In the other case, MRI showed a large area of insufficient enhancement in the anterior pituitary consistent with pituitary infarction or Sheehan's syndrome. We performed neurosurgical decompression via a transsphenoidal approach. Both patients showed an uneventful recovery. Both cases of isolated third cranial nerve palsy with ptosis completely resolved during the early postoperative period. We suggest that pituitary apoplexy should be included in the differential diagnosis of patients presenting with isolated third cranial nerve palsy with ptosis and that prompt neurosurgical decompression should be considered for the preservation of third cranial nerve function.

A case of visual loss following cranio-maxillofacial trauma is reported. The patient had acute optic nerve injury associated with a fracture of the right zygomaticomaxillary and fronto-naso-ethmoido-orbital bone and epidural hematoma on the right temporal lobe of brain. Bony fragments compressing the optic nerve on lateral side was identified on computed tomography. Decompression of the optic nerve combined with evacuation of epidural hematoma has been performed via transfrontal craniotomy. The patient had complete recovery of visual acuity without any complications. The role of optic nerve decompression in the management of patients with traumatic optic neuropathy is discussed. Surgical indication is controversial and the procedure should be considered only within the context of the specific indication of the individual patient.
