Introduction: Intraoperative electrophysiological studies are increasingly used in spinal surgery. However, its use in myelomeningocele (MMC) surgery is still not widespread. The aim of this study was to present our experience in neural placode (NP) and nerve root stimulations in newborns with open MMC. Methods: Eight newborns underwent surgical treatment for thoracolumbar and lumbosacral MMCs. Intraoperative neuromonitoring including free-running electromyography and stimulation of NP, nerve roots, and spinal cord were performed in all cases. Stimulation sites and intensities and distal response's amplitudes and latencies were recorded. Results: Five patients had thoracolumbar and 3 patients had lumbosacral MMC. Two patients had no movements at the lower extremities while the other had some movements. No response on the lower extremities was obtained in only 1 patient. Responses from the nerve root stimulations were more robust and significant than the placode stimulations. Conclusions: It is clear that the NP and nerve roots originating from the placode are mostly functional and should be preserved during the surgery. Intraoperative neuromonitoring and direct stimulation should be performed during the MMC repair in order to obtain a better neurological outcome. [ABSTRACT FROM AUTHOR]

Objective: Giant intracranial meningiomas are a challenge for neurosurgeons because of their size and location in the cranium. Difficult tumor dissection and encasement of important neurovascular structures make them a horrible nightmare. The aims of this study are to present our giant intracranial meningioma series and to compare our experience using advanced surgical technology with the current literature. Materials and Methods: The data of patients with the diagnosis of giant intracranial meningioma between 2014 and 2020 who underwent surgical treatment were retrospectively reviewed. The demographic, radiological, and surgical characteristics of patients were documented. The size and location of tumors as well as surgical technique were analyzed in detail. Results: A total of 61 patients with intracranial meningioma underwent surgical treatment over a 7-year period, and 10 (16.4%) tumors were larger than 5 cm in diameter, which were classified as giant meningioma. Seven patients were male and 3 were female, with a mean age of 64.9 years. Four tumors were located at the skull base. Histological diagnosis was meningioma World Health Organization grade I in 7 patients and grade II in 3 patients. Simpson grade 1 resection was achieved in 6 patients and grade 2 resection in 4 patients. No mortality was observed. Conclusion: Careful surgical planning should be made for giant intracranial meningiomas. Their location, adjacent neurovascular structures, and vascular supply affect the resection level of these giant tumors. Simpson grade 1 resection is seldom possible for skull base meningiomas.

Aims: To present our spinal intradural tumor series and to evaluate the reliability of electrophysiological assessment in patients treated for these tumors. Methods: We retrospectively evaluated the data of patients treated for spinal intradural tumor between 2010 and 2019. The demographic, surgical and histological features of patients were evaluated and compared with their pre- and postoperative electrophysiological data. Somatosensory evoked potentials (SEP) were used as electrophysiological test. Results: A total of 69 patients with spinal intradural tumor was evaluated. Thirty-one of them had extramedullary and 38 had intramedullary tumor. The mean age was 48.3 years for extramedullary and 26.3 years for intramedullary tumors. In preoperative period, SEP was prolonged in 25 patients with intramedullary tumor while it was prolonged in 8 patients with extramedullary tumor. In postoperative period, recovery in SEP values was detected in 5 of 25 patients with intramedullary tumor but it was observed in 7 of 8 patients with extramedullary tumor. Conclusions: Electrophysiological evaluation is a safe and reliable method to assess the patients surgically treated for spinal intradural tumor. It is an objective method to evaluate the neurological recovery of patients with extramedullary tumor. [ABSTRACT FROM AUTHOR]

Aims: Intracerebral hemorrhages (ICH) are usually seen in patients with stroke. In this pathology; ICH volume, location of the hemorrhage and hemorrhage expanding into the ventricular system are the main factors affecting the mortality respectively. Increase in ICH volume often results in neurological deterioration. Our aim is to determine the prognostic factors in patients who underwent surgical treatment for ICH. Methods: We retrospectively evaluated 52 patients operated in our department due to ICH which occurred spontaneously or were caused by the other etiological factors between 2017 and 2019. The parameters were the Glasgow Coma Scale (GCS) score, ICH volume in computed tomography scan, and ventricular expansion of the hemorrhage. Results: The mortality rate in our series was 61.5%. Mortality was significantly increased in patients with hematoma larger than 60 cm3. Nineteen of 24 (46%) patients with GCS scores between 3 and 8 died in the postoperative period. The mean duration of hospital stay was 33 days. 73% of the hematomas were seen in the lobar region. Conclusions: Low GCS score at admission and high ICH volume are prognostic factors for patients who have undergone surgery for ICH. [ABSTRACT FROM AUTHOR]

Aims: Split cord malformations (SCM) are congenital anomalies of the spine. The spinal cord is divided into two hemicords in the vertical plane. With foot and spine deformities, the skin lesions on the midline, even at the level of the lesion, at the back are the main signs of SCM. It is divided into two types as Type I (Diastometamyelia) and Type 2 (Diplomyelia). We retrospectively reviewed our cases with SCM and presented our results. Methods: In our department, 27 cases of SCM in 2012-2018 were surgically treated. Of these, 23 were Type I, 4 were Type II. In type I SCM, the bone septum was removed, the hemicords were assembled in a single dura, and the spinal cord was released. In type II SCM, fibrous band was removed and spinal cord was released. Results: All patients were recovered well after surgery. No mortality had been occured. Cerebrospinal fluid (CSF) fistula was seen in 4 patients. The complications such as CSF fistula, infection or wound problems were properly managed. Conclusions: In this paper, we tried to mention about preoperative preparation, intraoperative surgical steps and postoperative period of SCMs. Surgical technique and steps were especially emphasized. SCMs should be treated surgically as soon as possible after the birth in order to avoid neurological and urological deterioration. [ABSTRACT FROM AUTHOR]

Background: Pituitary apoplexy is an emergent and potential life-threatening complication of pituitary adenomas if not managed properly. The aim of our study is to present our series of pituitary adenomas and to focus on the clinical, radiological, and surgical characteristics of this rare complication., Methods: In this study, a total of 143 patients with pituitary adenoma underwent surgical treatment between 2016 and 2018. All patients were operated using endoscopic endonasal transsphenoidal (EET) technique. The data of pituitary apoplexy cases were recorded. Resection rates, hormonal results, and visual outcomes of patients with pituitary apoplexy were evaluated., Results: Of the 143 patients, 8 (5.59%) were presented with the symptoms and radiological findings of pituitary apoplexy. The mean age was 26.75 years, and 4 (50%) of them were male and 4 were female. Pre-operative mean Knosp grading score was 2.1 All of eight patients underwent emergent surgical intervention and total resection was achieved in 75% of patients with apoplexy. Hormone levels were significantly decreased after surgery (p<0.05), except prolactin (p>0.05). Cerebrospinal fluid leakage occurred in one pa-tient. None of the patient with pituitary apoplexy died in our series., Conclusion: Pituitary apoplexy is an important complication of pituitary adenomas. Early diagnosis and surgical intervention provide excellent ophthalmological and hormonal outcomes. Emergent EET approach is crucial for patients with ophthalmological findings and macroadenomas.

Background: The aim of this study was to retrospectively evaluate patients who underwent surgery in our department for radial nerve lesions in terms of surgical outcomes., Methods: Thirty-eight patients were admitted to our department with radial nerve lesion. Twenty-seven of the patients had entrapment neuropathy and 11 had radial nerve injury secondary to other traumas. Various factors such as surgical results, time to surgical intervention, injury mechanism, and reconstruction technique were analyzed., Results: In all of 27 patients who were operated for radial nerve entrapment neuropathy, a complete improvement in wrist dorsal flexion was detected at postoperative 3rd month. Seven of the 11 patients who were operated for radial nerve lesion had different degrees of improvement in wrist dorsal flexion at the postoperative 3rd month. Two of the seven patients underwent anastomosis using a sural nerve graft. The recovery rate in our series was 89%. Three of the 4 patients who did not recover after the radial nerve injury were the patients who were operated within the 1st month after the trauma., Conclusion: Better functional results were obtained in the postoperative period in patients who were operated after the 1st month, underwent internal neurolysis and used a short nerve graft for anastomosis in the radial nerve lesions. In patients with entrapment neuropathy, the earliest surgery revealed satisfactory results in the postoperative period.

Background: Peripheral nerve injuries are usually not lethal but may cause serious neurological deficits if not treated properly. The aim of this study is to present our patients who underwent surgical treatment for peripheral nerve trauma in the past 10 years and to discuss their results in light of the literature., Methods: The clinical and electrophysiological results of 182 patients who underwent surgical treatment in our department between 2010 and 2019 were retrospectively analyzed. All surgeries were performed using intraoperative nerve action potentials (NAP) recordings. Demographic characteristics, etiologies, surgical timing, and results of surgical treatment were recorded., Results: A total of 199 surgical interventions were performed in 182 patients with peripheral nerve trauma within 10 years. 162 patients were male, 20 were female and the mean age was 29.34 years for males and 30.2 years for females. The sciatic nerve trauma was the most common in men and peroneal nerve injury women. The most common cause of trauma was gunshot wounds in menand blunt/sharp traumas in women. External and internal neurolysis was the most common surgical technique, followed by epineural anastomosis and sural nerve grafting. 155 of 182 patients showed partial neurological improvement within 3 months after surgery, while 27 had no change in their neurological condition., Conclusion: Men are more frequently exposed to peripheral nerve trauma than women. Severe partial nerve lesions mostly benefit from surgical treatment, and neurolysis has become the most preferred method of surgical treatment. Intraoperative NAP recordings provide better clinical outcomes. Neurological improvement may not always be in correlation with electrophysiological improvement.

Background: External ventricular drainage (EVD) is a life-saving and emergent procedure in neurosurgery. However, infection is the main problem in patients with EVD. The present study aims to analyze the infection rate of patients with EVD and to investigate the factors that contribute to infection and mortality rates., Methods: The data of patients who underwent emergent EVD procedure between 2018 and 2019 were retrospectively analyzed in this study. The demographic features of the patients were recorded. The correlation between age, gender, indication and duration of EVD, and the infection and mortality rate were investigated., Results: In this study, 47 patients underwent emergent EVD in two years. Thirty (63.83%) patients were male, and 17 were female with a mean age of 28.02 years. The mean duration of drainage was 6.2 days. Fifty-eight cerebrospinal fluid (CSF) samples were analyzed during the drainage period and CSF culture was positive in 14 (24.14%) samples. The most common microorganism was Staphylococcus epidermidis. The infection rate was high in older and male patients with duration longer than six days. Nine (19.15%) patients died during the treatment period and six of them had IVH., Conclusion: The duration of EVD should be shorter in patients older than 65 years with the diagnosis of intraventricular hemorrhage, which is mostly related to dea.

Background: Craniocerebral gunshot wounds (CGW) are the most lethal injuries of the cranium. CGW is mostly secondary to military conflicts but may also be seen in civilian life. These injuries also have severe consequences, such as epilepsy, hydrocephalus, infection and late-term cognitive dysfunctions. The present study aims to present our series of CGW and to discuss the prognostic factors and consequences of these injuries., Methods: The data of patients who were treated in our department for CGW between 2011 and 2019 were retrospectively reviewed in this study. The injury type, wounding site, surgical management and outcomes were analyzed. Radiological evaluation was also performed., Results: Thirty patients were treated with the diagnosis of CGW. All of the patients were male and the mean age was 27.9 years. The frontal lobe was affected in 12 (40%) patients, while temporal lobe in eight, occipital lobe in six, parietal lobe in three, and posterior fossa in one patients. Twenty-three patients underwent surgical treatment, seven patients were treated conservatively. Thirteen (43.3%) patients died despite the treatment., Conclusion: Mortality in CGW is high. Ventricular injuries, bihemispheric or midline injuries, perforating injuries, brain stem injuries and low GCS score at admission are prognostic factors for CGW. Appropriate management is mandatory to obtain a better clinical outcome.

Background: This study aims to investigate the clinical outcomes of patients who underwent closed continuous lumbar drainage (CLD) for post-traumatic cerebrospinal fluid (CSF) fistula and to compare with those of non-traumatic patients., Methods: The data of patients who were treated in the department of neurosurgery between January 2018 and December 2019 and underwent CLD were analyzed. The diagnosis, demographic characteristics, CSF results and clinical outcomes of these patients were evaluated. The outcomes of the patients with dura defect and CSF fistula due to trauma were compared with patients who underwent CLD for other diagnoses., Results: In this study, 45 patients underwent CLD for 51 times. The mean age was 38.84 years, and 27 (60%) of the patients were male. Seven (15.55%) patients underwent CLD due to post-traumatic CSF fistula and 38 patients after tumor or malformation surgery. While five patients developed CSF fistula due to dura defect after gunshot injury, two patients developed CSF fistula secondary to motor vehicle accident. Staphylococcus Epidermidis was isolated in one patient among post-traumatic CSF fistula patients while Serratia Marcescens was isolated in patients with CSF fistula secondary to posterior fossa tumor surgery. While none of the seven patients died during the follow-up period in post-traumatic group, one of the 38 patients with CLD secondary to tumor surgery was lost due to sepsis in the follow-up period., Conclusion: CLD in post-traumatic CSF fistulas is a safe and effective treatment method. Especially in patients with gunshot wounds, CLD should be performed before revision surgery in the treatment of CSF fistula. Studies with different parameters are needed in larger trauma populations.

Background: We aim to present our series on pediatric head traumas and discuss our results with the current literature., Methods: The data of children who underwent treatment for head trauma in our department between 2010 and 2019 were retrospectively reviewed. Their clinical condition at admission, radiological findings, treatment methods and outcomes were analyzed., Results: Ninety children underwent treatment for head trauma, 60 of them were male and 30 were female. The mean age was 6.6 years. Linear skull fracture was seen 55 patients, while epidural hematoma in 15 patients. Twenty patients underwent surgical treatment, while 70 patients underwent conservative treatment. No patient died in our series, three patients underwent rehabilitation due to neurological deficits after discharge., Conclusion: Children were more prone to head trauma, but their mortality was less than the adults. Conservative treatment should be the first goal, but surgical management should be reserved for children with significant hematoma and declining neurological conditions.
