  • Understanding the development of a skull deformity requires an understanding of the normal morphogenesis of the cranium. Craniosynostosis is the premature, pathologic ossification of one or more cranial sutures leading to skull deformities. A review of the English medical literature using textbooks and standard search engines was performed to gather information about the prenatal development and growth of the cranial vault of the neurocranium. A process of morphogenic sequencing begins during prenatal development and growth, continues postnatally, and contributes to the basis for the differential manner of growth of cranial vault bones. This improved knowledge might facilitate comprehension of the pathophysiology of craniosynostosis.

  • A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

  • This study was performed to report the effectiveness of upper cervical chuna and release of cranial base on patients with dry eye syndrome. The patients diagnosed as dry eye syndrome and treated with upper cervical chuna and release of cranial base. Outcomes were measured by ocular surface disease index(OSDI). After treatments, discomfort and ocular surface disease index decreased. These results suggest that upper cervical chuna and release of cranial base were effective on patients with dry eye syndrome.

  • Anterior cranial fossa dural arteriovenous fistulae (DAVFs) are very rare and the bleeding rate is very high, especially in the presence of leptomeningeal draining vein and aneurysmal varix formation. A 85-year-old male patient presented with subdural hematoma (SDH). Magnetic resonance image (MRI) and transfemoral carotid angiography (TFCA) disclosed DAVF at the anterior cranial fossa with bilateral arterial feeders and leptomeningeal draining vein with varix formation. The lesion was treated by simple ligation of pial connecting vein using low frontal craniotomy. In comparison with DAVFs of the other sites, the anterior cranial fossa DAVF is difficult to manage by endovascular treatment due to not only the difficulty of transvenous access but the risk of visual impairment when using transarterial route. Surgical ligation of pial connecting vein is feasible and effective treatment.

  • 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.

  • Varicella-zoster virus(VZV) becomes latent in the sensory ganglia after primary infection and emerges from latency to cause zoster in adults. After primary infection, VZV remains latent in the dorsal spinal ganglia. The mechanisms responsible for its reactivation and the clinical entity of herpes zoster are poorly understood. Reactivation of VZV is commonly known to manifest as Ramsay Hunt syndrome which is one of the VZV-associated neurologic diseases with facial paralysis, ear pain, and a characteristic herpetic auricular rash. It is now known that lesions of this syndrome can affect all cranial nerves. Central, cervical and peripheral effects of this syndrome is polyneuropathic in nature. VZV usually involves the 5th and 7th cranial nerves and less commonly the lower cranial nerves such as 9th and 10th. We report a treated case of healthy 40 years old male with VZV infection of the 5th, 9th and 10th cranial nerves. The patient typically showed herpetic vesicles in the auricle and temporal bone area without facial paralysis.

  • Cranial implant removal is recommended if implants become exposed owing to scalp necrosis after cranioplasty. However, it carries the risk of extensive bleeding, and the resultant cranial defects can cause both aesthetic and functional problems. We present a case of a scalp defect exposing a cranial prosthetic implant that was reconstructed with a local flap and salvaged using an indwelling antibiotic irrigation system. A 73-year-old man presented with scalp necrosis after undergoing cranioplasty due to intracranial hemorrhage. The cranial implant was exposed through the scalp defect. Methicillin-resistant Staphylococcus aureus was detected in the culture from the open wound. After debridement of the necrotic tissue and burring of the superficial layer of the implant, a transposition flap was used to cover the defect and an indwelling antibiotic irrigation system was installed. Continuous irrigation with vancomycin was conducted for 5 days, and intravenous vancomycin was continued for 4 weeks. The flap was in good condition at 4 months postoperatively, with no infection. The convex contour of the scalp was well maintained. The patient's neurological status was stable. Exposed cranial implants can be salvaged with continuous antibiotic irrigation as an alternative to implant removal; thus, the risk of bleeding and possible disfigurement may be avoided.

  • Purpose The head of infants under 24 months old who has Craniosynostosis grows extraordinarily that makes head shape unusual. To diagnose the Craniosynostosis, surgeon has to inspect computed tomography(CT) images of the patient in person. It's very time consuming process. Moreover, without a surgeon, it's difficult to diagnose the Craniosynostosis. Therefore, we developed technique which detects Craniosynostosis automatically from the CT volume. Materials and Methods At first, rotation correction is performed to the 3D CT volume for detection of the Craniosynostosis. Then, cranial area is extracted using the iterative thresholding method we proposed. Lastly, we diagnose Craniosynostosis by analyzing centroid relationships of clusters of cranial bone which was divided by cranial suture. Results Using this automatical cranial detection technique, we can diagnose Craniosynostosis correctly. The proposed method resulted in 100% sensitivity and 90% specificity. The method perfectly diagnosed abnormal patients. Conclusion By plugging-in the software on CT machine, it will be able to warn the possibility of Craniosynostosis. It is expected that early treatment of Craniosynostosis would be possible with our proposed algorithm.

  • 성인의 급성 백혈병 환자 64예를 1990년 1월부터 1991년 10월 사이에 충남대학교 병원에서 치료하였다. 극심한 백혈구 증다증이 동반된 20예를 선별하여 네가지 각기 다른 방법으로 치료하였으며 이 치료양상에 따른 급성 사망율과 완해율에 관하여 조사하여 보았다. 응급 두개부 방사선 조사 단독 또는 항암제 약물요법을 병행한 경우에 있어서 단지 보조적 요법만을 시행한 경우나 항암제 약물요법만을 시행한 경우에 비하여 초기 급성 사망율이 낮았다. 또 완해율에 있어서도 응급 두개부 방사선 조사 및 항암제 약물요법을 병행한 경우에 높았다. 따라서 우리는 성인의 급성 백혈병에서 극심한 백혈구 증다증이 동반된 경우 조기 두개부 방사선 조사가 초기 급성 사망율을 낮추고 후에 완해율을 높이는 데에도 효과가 있을 것이라고 추정해보았다.

  • 두 마리 개가 (증례 1: 27 kg, 증례 2: 42 kg) 뒷다리 파행을 주증으로 내원하였다. 신체검사상, 증례 1은 무릎 검사 시 중증도 통증과 마취 상태에만 경골의 전위 증후을 보였고 증례 2는 과신전시 불편함을 호소하였으나 마취 전후 모두 전위 증후는 관찰되지 않았다. 방사선검사에서 두 증례 모두 관절 내 종창을 확인할 수 있었다. 위의 검사를 바탕으로 전십자인대 단열을 의심하고 관절경을 실시하였다. 관절상에서 증례 1은 불안정한 부분 전십자인대 단열을 증례 2는 안정화된 부분 전십자인대 단열로 진단하였다. 두증례 모두 경골조면 전이동술을 이용하여 치료 하였다. 증례 2에서 술 후 수술 부위에 장액종이 발생하여 수술적으로 제거하였다. 수술 5개월 후 두 증례 모두 임상증상이 개선되었다. 이 증례들을 바탕으로 경골조면 전이동술은 부분 전십자인대 단열에서 유용한 치료법으로 사료된다.
