  • Gunshot wounds are rare in Korea, but they have tended to increase recently. We experienced an interesting case of penetrating gunshot injuries to the cervical spine with migration the fragments of the bullet within the dural sac of the cervical spine, so discuss the pathomechanics, treatment and complications of gunshot wounds to the spine and present a review of the literature. A 38-year-old man who had tried to commit suicide with a gun was admitted to our hospital with a penetrating injury to the anterior neck. the patient had quadriplegia. A Computed tomography (CT) scan and 3-dimensional CT of the spine showed destruction of the left lateral mass and lamina of the 5th cervical vertebra; the bullet and fragments were found at the level of the 5th cervical vertebra. The posterior approach was done. A total laminectomy and removal of the lateral mass of the 5th cervical vertebrae were performed, and bone fragments and pellets were removed from the spinal canal, but an intradurally retained pellets were not totally removed. A dural laceration was noted intraoperatively, and CSF leakage was observed, so dura repair was done watertightly with prolene 6-0. The dura repair site was covered with fibrin glue and Tachocomb$^{(R)}$. Immediately, a lumbar drain was done. Radiographs included a postoperative CT scan and X-rays. The postoperative neurological status of the patient was improved compared with the preoperative neurological status. however, the patients developed symptoms of menigitis. He received lumbar drainage(200~250 cc/day) and ventilator care. After two weeks, panperitonitis due to duodenal ulcer perforation was identified. Finally, the patient died because of sepsis.

  • Objective : Removal of the anterior clinoid process (ACP) is an essential process in the surgery of giant or complex aneurysms located near the proximal internal carotid artery or the distal basilar artery. An extradural clinoidectomy must be performed within the limits of the meningeal layers surrounding the ACP to prevent morbid complications. To identify the safest method of extradural exposure of the ACP, anatomical studies were done on cadaver heads. Methods : Anatomical dissections for extradural exposure of the ACP were performed on both sides of seven cadavers. Before dividing the frontotemporal dural fold (FTDF), we measured its length from the superomedial apex attached to the periorbita to the posterolateral apex which connects to the anterosuperior end of the cavernous sinus. Results : The average length of the FTDF on cadaver dissections was 7 mm on the right side and 7.14 mm on the left side. Cranial nerves were usually exposed when cutting FTDF more than 7 mm of the FTDF. Conclusion : The most delicate area in an extradural anterior clinoidectomy is the junction of the FTDF and the anterior triangular apex of the cavernous sinus. The FTDF must be cut from the anterior side of the triangle at the periorbital side rather than from the dural side. The length of the FTDF incision must not exceed 7 mm to avoid cranial nerve injury.

  • Elderly patients with acute subdural hematomas have higher mortality and lower functional recovery rates compared with those of other head-injured patients. Early and widely surgical decompression and active intensive care represent the best way to assist these patients. However, abrupt decompression of the hematoma can lead to brain disruption and secondary ischemia in the brain surrounding the craniectomy site. Acute brain swelling and brain extrusion, which take place shortly after decompression, can lead to a catastrophic situation during the operation due to the impossibility of appropriate closure of the dura and scalp. To avoid the deleterious consequences of disruption of brain tissue, we have adopted multiple fenestrations of the dura in a mesh-like fashion and gradual release of subdural clots through the small dural openings that are left open. This is especially important in cases in which there are massive amount of subdural hematomas with small parenchymal lesion and severe midline shifts in elderly patients. Further clinical experiences should be conducted in a more selected series patients to estimate the impact of this technique on morbidity and mortality rates.

  • Cervical epidural steroid injection is frequently used in the conservative management of neck pain and cervical radiculopathy. Epidural cervical transforaminal injections are usually well-tolerated with mild side effects such as transient decreased sensory and motor function, or headache due to dural puncture. Although there are a few case reports about adverse effects of cervical epidural injection in the literature, it can cause severe complications such as large hematoma, infarction by spinal vascular injury. Subdural hematoma has been occurred much less common rather than epidural hematoma in the spinal cord. We report a rare catastrophic case of cervical spinal subdural hematoma with quadriparesis after cervical transforaminal epidural block.

  • Vertex epidural hematoma (VEH) is an uncommon presentation of all epidural hematomas and presents with a wide range of symptom and signs. Diagnosis as well as treatment of VEH is also difficult because of its location adjacent to superior sagittal sinus (SSS). A 43-year-old male visited our hospital after fall down and was diagnosed with VEH. While evaluating its location and patency of SSS, he was deteriorated and urgently underwent evacuation of VEH. Bilateral craniotomies on each side, leaving a central bony island to avoid bleeding of midline structure and provide an anchor for dural tack-ups. After the operation, VEH was totally removed and the patient has restored.

  • Background The prosthetic dura is an essential element in the protection of the cranial parenchyma and prevention of cerebrospinal fluid leakage. Although prosthetic dura are widely used in neurosurgery, they occasionally provoke infection, which can be a major concern after neurosurgical treatment. However, removal of the prosthetic dura carries a risk of brain parenchyma injury and cerebrospinal fluid leakage. The salvage of infected prosthetic dural material has not been adequately addressed in the literature. In this study, we demonstrate the value of the combination of a meticulous surgical debridement of necrotic tissue and simultaneous muscle free flap for intractable postoperative epidural abscess without removal of the infected prosthetic dura. Methods Between 2010 and 2012, we reviewed the data of 11 patients with persistent infection on the prosthetic dura. The epidural infections each occurred after a neurosurgical procedure, and there was soft tissue necrosis with the disclosure of the underlying prosthetic dura and dead bone around the scalp wound. To salvage the infected prosthetic dura, meticulous debridement and a muscle free flap were performed. Results All 11 patients experienced complete recovery from the complicated wound problem without the need for further surgical intervention. No signs of prosthetic dural infection were observed during the mean follow-up period of 11 months. Conclusions The combination of a meticulous surgical debridement and coverage with a muscle free flap is an effective treatment for salvage of infected prosthetic dura.

  • The purpose of spinal dural arteriovenous fistula (SDAVF) ligation is to prevent neurological injury and the poor blood supply through ligation of arteriovenous fistula. Therefore, intraoperative neurophysiological monitoring (INM) is required via multimodal neurological examination for minimizing the side effects after surgery based on the patient's symptoms. Transcranial electric motor-evoked potentials (TceMEP) help to check the condition of the corticospinal tract. Whenever ligation is performed, TceMEP should be performed every minute to check for abnormalities. However, an examiner's lack of knowledge about the operation procedure and examination and also poor communication between the examiner and surgeon can cause incorrect timing of the stimulation of TceMEP that interferes with the procedure and causes side effects such as paralysis and motor weakness. As a result of this SDAVF ligation survey, it is believed that for proper INM, case reports will be needed along with further research and the examiner will also have to work closely with the surgeon to minimize neurological damage to patients.

  • Objective : The classic and accepted surgical method of compound comminuted depressed skull fractures (FCCD) involves total resection of all the contaminated bone and fragments at the fracture site. A second operation for cranioplasty is then performed at a later date. However, we have believed that primary repair of these bony defects can be achieved by the replacement of bone fragments at the time of the initial debridement, and this can be accomplished without danger to patient. The authors retrospectively reviewed the surgical results to assess the advantages and disadvantages, and also propose the selection criteria of replacement of fractured bone fragments as a primary procedure in FCCD. Materials and Methods : The authors analyzed the data extracted from medical records, and radiological findings in 22 of 71 patients with FCCD, who underwent immediate replacement of fractured bone fragments between April 1993 and October 1998. The mean follow-up period was 13.7 months. The selection criteria for the operation included the patients with mild to moderate severity, regardless of the degree of contamination or dural violation, which presented in hospital within 24 hours of injury. Results : The ages of the patients varied from 4 to 63 years, and there were 20 males and 2 females. Seventeen of 22 patients were fully conscious on admission and the others also had relatively good Glasgow coma scales. Sixteen fractures were located in the frontal area, 9 with involvement of the frontal sinuses, and 6 in the parietal and temporoparietal areas. Of the 22 patients, 8(36.3%) had dural lacerations with 3 of these requiring patching with pericranium, and 12(54.5%) had intracranial hematoma requiring wide craniotomy. The degree of wound contamination was also variable. Fifteen patients had relatively clean wounds, while seven(31.8%) had seriously contaminated wounds with soil, sand, hair, and wood. Only one patient(4.5%) developed infection, and the bone fragments were removed. All wounds healed primarily without pulsatile defect, the skull has remained solid, and no complications have occurred, except the infected case. Conclusion : It is proposed that bone fragments removal for FCCD, regardless of the degree of contamination or dural violation, is not necessary and that primary bone fragments replacement avoids a second operation for cranioplasty.

  • Objective: To assess the efficacy of cervical open-door laminoplasty by hydroxyapatite implant insertion between the lamina and the lateral mass without suturing. Methods: All patients who underwent cervical open-door laminoplasty with C2/C7 undermining and insertion of hydroxyapatite implants from C3 to C6 were retrospectively evaluated for surgical time and neurological outcomes according to the Japanese Orthopaedic Association (JOA) score. To assess the alignment of the cervical spine and postoperative cervical pain, the C2-7 angle and a visual analogue scale score were used, respectively. Results: The population consisted of 102 women and 222 men ranging in age from 32 to 90 years. The average surgical time was 86 minutes. Fourteen of 1,296 hydroxyapatite implants were kept in place with sutures due to a weak restoration force of the hinge during surgery. No hydroxyapatite implant dislocation was detected on cervical computed tomography at 1 year after surgery. The average JOA score was $10.2{\pm}2.5$ before surgery and $14.6{\pm}2.8$ at 1 year after surgery. The average recovery rate was 61.8%. The average C2-7 angle at the neutral position was $7.1^{\circ}{\pm}6.2^{\circ}$ before surgery and $6.5^{\circ}{\pm}6.3^{\circ}$ at 1 year after surgery. Conclusion: This method enabled us to achieve minimal exposure of the lateral mass, prevention of lateral mass injury and dural injury, and a shorter surgical time while maintaining acceptable surgical outcomes. The idea that firm suture fixation is needed to prevent spacer deviation during cervical open-door laminoplasty may need to be revisited.

  • Pneumocephalus after thoracoscopic excision of a mediastinal mass is a very rare complication. It presumably occurs due to dural injury near the spinal root and development of a subsequent subarachnoid-pleural fistula. A 60-year-old woman complained of nausea and headache after thoracoscopic excision of a posterior mediastinal mass. She was diagnosed with pneumocephalus by brain CT and recovered with supportive management.
