Endonasal endoscopic approach for sellar metastatic pathologies: a national observation.

PURPOSE: Sellar metastases are rare lesions. Recent improvements in diagnosis and treatment strategies have prolonged survival but increased the probability of metastatic tumors. Evaluation with clinical symptomatology and meticulous laboratory examination is crucial. We present our multicenter national study on sellar metastases to evaluate and underline the main clinical, endocrine, and radiological considerations regarding the diagnosis and endonasal endoscopic management of such rare lesions. METHODS: A medical literature-based retrospective study was planned across 13 neurosurgical centers in Turkey, where a data survey was conducted to collect information regarding sellar metastases surgically treated using the endoscopic endonasal approach, including clinical presentation, radiographic features, primary tumor origin, histopathological confirmation, time to metastasis, treatment, and patient outcomes. RESULTS: Between 2010 and 2020, 54 patients (22 women [40.7%] and 32 men [59.3%]) who underwent surgery with the endonasal endoscopic approach and had pathologically proven sellar metastases (overall incidence, 0.54%) were included. Of the patients, 59.3% had no known malignancy and presented with new-onset symptoms, 79.6% reported headache, 51.9% complained of some degree of visual deficits, and 50% had cranial nerve symptoms. Tissue biopsy was performed in 7.4% of the patients, whereas gross or subtotal resection was achieved in the remaining patients. CONCLUSION: To our knowledge, this is the largest series of patients surgically treated with the endonasal endoscopic approach for sellar metastases. For these patients, the treatment focus should be on management modalities for increasing quality of life instead radical treatment options with survival benefit.

Endoscopic Untethering of Tight Filum Terminale: An Operative Technique.

AIM: To demonstrate the various technical advantages of minimally invasive endoscopic untethering of tight filum terminale for the treatment of tethered cord syndrome (TCS). MATERIAL AND METHODS: In five pediatric cases of TCS, we performed untethering by using the endoscopic technique. The age of the patients were 6, 7, 8, 9, and 12 years old. We used a nasal speculum of the transsphenoidal approach during the endoscopic surgical procedure. RESULTS: All the procedures were performed uneventfully, except for one case with a split cord malformation that showed neurologic deterioration caused by excision of the diastematomyelic fibrous septum at the thoracic level (unrelated to the endoscopic procedure at the L5-S1 level). This patient was referred to a rehabilitation clinic 5 days after surgery and showed significant improvement by the third postoperative month. The other four patients were discharged 1 day after the operation. CONCLUSION: Endoscopic release of filum terminale is a safe technique especially if it is performed with neuromonitoring. This technique may shorten the length of hospital stay and reduce perioperative blood loss. However, futher studies with a larger number of patients and long-term follow-up are needed.

Clinical and hormonal characteristics of patients with different types of hypophysitis: a single-center experience.

OBJECTIVE: The inflammation of the pituitary gland is known as hypophysitis. It is a rare disease accounting for approximately 0.24%-0.88% of all pituitary diseases. The natural course of hypophysitis is variable. Main forms are histologically classified as lymphocytic, granulomatous, IgG4 related and xanthomatous. We aim to present our patients with hypophysitis and compare clinical, laboratory and radiological features. SUBJECTS AND METHODS: We retrospectively reviewed our database of 1.293 patients diagnosed with pituitary diseases between 2010 and 2017. Twelve patients with hypophysitis were identified. Demographical data, clinical features, endocrinological dysfunction, imaging findings, treatment courses and follow-up periods were evaluated. RESULTS: The frequency of hypophysitis was found 0.93% in all cases of the pituitary disease. Twelve patients (nine females and three males), ages between 17-61 years, were evaluated. The characteristic features of our patients tended to be predominantly female and young. Diagnosis of hypophysitis was made after pituitary biopsy in four patients, and in eight patients after pituitary operation due to adenoma. Headache (67%) and visual problems (33%) were the most frequent nonendocrine symptoms. Anterior pituitary hormone deficiencies (63.7%) and/or diabetes insipidus (17%) were seen among patients. According to histopathological forms, four had lymphocytic, seven had granulomatous and one had xanthogranulomatous types. Contrast enhancement heterogeneous and thickened pituitary stalk were the most common radiological alterations. CONCLUSION: Hypophysitis should be considered in the differential diagnosis of sellar masses. It can mimic pituitary adenomas in radiological and endocrinological aspects. The different patterns of pituitary hormone deficiencies may be seen in the course of the disease.

Primary Central Nervous System Lymphoma of Optic Chiasma: Endoscopic Endonasal Treatment.

BACKGROUND: Isolated primary central nervous system lymphoma arising from anterior visual pathway is very rare. PATIENT PRESENTATION: A 76-year-old immunocompetent previously healthy man presented bilateral decreased visual acuity in 1 month. Pituitary magnetic resonans imaging (MRI) showed a lobulated mass with homogeneous enhancement after gadolinium administration that arising from optic chiasm suggested that inflammatory disease or an optic glioma. The patient underwent an extended endoscopic endonasal transsphenoidal surgery. Postoperative course and outcomes were wonderful. Histopathological diagnosis was diffuse large B-cell lymphoma. The patient underwent investigations for systemic lymphomatous involvement, did not detect any evidence of systemic disease. CONCLUSION: In this case, we claimed that differential diagnoses of anterior visual pathway lesions are difficult because of similarity of lesions on clinical and radiological examinations. Biopsy is essential for these lesions. As a biopsy technique, endoscopic endonasal transsphenoidal approach is safer and more effective than open procedures.

Traumatic Acute Subdural Hematomas: Analysis of Outcomes and Predictive Factors at a Single Center.

AIM: In the present study, we evaluated the association of the Glasgow Coma Scale (GCS) score and amount of blood loss with mortality in patients presenting with traumatic acute subdural hematoma (ASDH). MATERIAL AND METHODS: This retrospective study was performed on 99 patients who were operated for traumatic acute subdural hematoma (ASDH) without any systemic association at a single center. Epidural hematoma was reported to be the most common additional pathology. Age, sex, mechanism of trauma, time interval between onset of trauma and admission to the emergency ward, associated problems, thickness of hematoma and Glasgow Coma Scale (GCS) score at the time of admission and on discharge were all studied. RESULTS: The GCS score was inversely proportional to the thickness of hematoma and interval between onset of trauma and surgery (p < 0.05). Although the mortality rate was reported to be high in traffic accidents, the rate was low in patients with head trauma only (p < 0.05). The mortality rate was high in patients with associated pathologies (p < 0.05). Lost patients were reported to be older patients with more extensive ASDH or those who presented earlier with a low GCS (p < 0.05). CONCLUSION: ASDH is associated with high mortality. GCS score and the thickness of the ASDH are important predictors of mortality. Age, additional trauma, and interval between trauma and hospital admission are major predictive factors for mortality.

Massive Skull Base Ameloblastic Carcinoma with Intracranial Extension.

Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor that may arise either from the mandible (66.6%) or the maxilla (33.3%). Besides being formed de novo, the tumor can develop from a pre-existing ameloblastoma or odontogenic cyst. The clinical course of AC is typically aggressive with extensive local destruction. AC has also been reported to spread to various parts of the body through lymphatic system. Skull base location and intracranial extension of this tumor are uncommon. In this case report we present the clinical course, management and follow up of an uncommonly large AC that destructed the anterior skull base and extended into the intracranial space.

Initial Discectomy Associated with Aging Leading to Adjacent Disc Disease and Recurrence.

AIM: Failure of surgery for lumbar disc herniation (LDH) can be commonly caused by recurrence. There are many debates regarding the risk factors of recurrent LDH (rLDH) and it is very difficult to define them because many clinical and complicated biomechanical parameters are involved. The purpose of study was to evaluate the long term result of re-discectomy for LDH at the same level and adjacent segments. MATERIAL AND METHODS: Between 1999 and 2009, 1898 cases were operated and 142 (6.4%) patients underwent re-discectomy following initial operation. The study included 65 patients who were operated for single level discectomy, and their charts were analyzed retrospectively. RESULTS: There were 33 (50.8%) women and mean age was 45.5 years (24-73 years). rLDH was diagnosed at the initial level in 40 (61.5%) but adjacent and/or opposite level herniation (with or without the first level) was found in the remaining 25 cases (39.1%). Recurrence at the same level (SLG) and adjacent level groups (ALG) were similar according to the clinical outcomes in follow-up (mean 34.1 months). Admission period after initial operation was also parallel in SLG and ALG (54.7 and 53.1 months, respectively). However, the mean age of ALG (49.4 years) was significantly higher (p≤0.05) than SLG (42.8 years). CONCLUSION: After discectomy, collapsed discs are biomechanically more stable than those with preserved disc heights, and responses to axial compression on intervertebral disc pressure produced deformations of adjacent levels despite limitations. Altered biomechanical loading next to a fusion resulted in ongoing degeneration with aging at the affected entire lumbar spine.

The Biochemical, Histopathological and Clinical Comparison of the Neuroprotective Effects of Subcutaneous Adalimumab and Intravenous Methylprednisolone in an Experimental Compressive Spinal Cord Trauma Model.

AIM: To evaluate the neuroprotective effects of adalimumab in an experimental spinal cord injury model and compare them with those of the widely-used methylprednisolone. MATERIAL AND METHODS: Forty male Wistar rats were divided into 5 as the sham, trauma, adalimumab, methylprednisolone, and adalimumab+methylprednisolone groups. Only laminectomy was performed in the sham group. Laminectomy and trauma was performed to the trauma group but no treatment was given. A single dose of 40 mg/kg subcutaneous adalimumab was administered after the laminectomy and trauma to group 3. A single dose of intravenous 30 mg/kg methylprednisolone was administered right after laminectomy and trauma to group 4. Single doses of 40 mg/kg adalimumab and 30 mg/kg methylprednisolone were administered together after laminectomy and trauma to group 5. Serum malondialdehyde (MDA), TNF-α, IL-1ß and IL-6 levels were measured and sections were obtained for histopathological study at the end of the 7 < sup > th < /sup > day. RESULTS: MDA, TNF-α, IL-1ß and IL-6 levels in serum were significantly decreased in the adalimumab group with clinical and histopathological improvement not less than the methylprednisolone group. The serum MDA levels were similar when the two drugs were given together or separately but there was a statistically quite significant decrease in TNF-α, IL-1ß and IL-6 levels with concurrent use. Statistically significantly better results were obtained on histopathological evaluation with the use of both drugs together. CONCLUSION: This study revealed that adalimumab is as effective as methylprednisolone in compressive spinal cord injury in rats.

Timing of Surgery for Spinal Fractures Associated with Systemic Trauma: A Need for a Strategic and Systemic Approach.

AIM: An underestimated evaluation of systemic organs in cases with spinal fractures might jeopardize the intervention for treatment and future complications with an increased morbidity and mortality are almost warranted. In the present study, a retrospective analysis of spinal fracture cases associated with systemic trauma was performed to assess surgical success. MATERIAL AND METHODS: A retrospective analysis of patients with thoracolumbar fractures who were admitted to the emergency unit between September 2012 and September 2014 was used for the study. The cases were categorized according to age, sex, reason of trauma, associated trauma, neurological condition and treatment details and results were analysed using SPSS 14.0 for Windows. RESULTS: The most common reason of trauma is detected as falls in 101 cases (64.3%). Radiological evaluation of spinal fractures revealed a compression fracture in 106 cases (67.5%) and other fractures in 51 cases (32.5%). Surgical treatment for spinal fracture was performed in 60.5% of the cases and conservative approach was preferred in 39.5% cases. In non-compressive spinal fractures, an associated pathology like head trauma, lower extremity fracture or neurological deficit was found to be higher in incidence (p < 0.05). Necessity for surgical intervention was found to be more prominent in this group (p < 0.05). However, the fracture type was not found to be associated with morbidity and mortality (p < 0.05). CONCLUSION: A surgical intervention for a spinal fracture necessitating surgery should rather be performed right after stabilization of the systemic condition which might be associated with decreased morbidity and mortality.

Neuroprotective effects of adalimumab on rats with experimental peripheral nerve injury: An electron microscopic and biochemical study.

BACKGROUND: Adalimumab, a new-generation anti-inflammatory agent, exerts its effect through tumor necrosis factor α (TNF-α), secreted from immune response cells such as macrophages and lymphocytes. TNF-α has been shown to play an important role in the processes of apoptosis and demyelination, and blockage of its activity may improve neural healing. Investigated in the present study is the probable neuroprotective influence of adalimumab in rats using a peripheral nerve injury model with biochemical and electron microscopic methods. METHODS: Forty adult Wistar albino rats were randomly divided into control, sciatic nerve trauma, low-dose adalimumab, and high-dose adalimumab groups. Six rats from each group were assigned biochemical microscopy, and 4 were assigned electron microscopy. Neural injury was induced with clip compression following dissection of sciatic nerves. Adalimumab was simultaneously injected. The rats were sacrificed after 2 weeks of adalimumab treatment. RESULTS: Nerve tissue lipid peroxidation values were found to be significantly decreased in both the low- and high-dose adalimumab treatment groups, compared to the group subjected only to sciatic nerve trauma. CONCLUSION: Results demonstrate that adalimumab is an effective neuroprotective agent for neural healing, particularly in the early phase.

A case of delayed carotid cavernous fistula after facial gunshot injury presented as loss of vision with symptom resolution after endovascular closure procedure.

Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus (CS), and can occur as a result of blunt and penetrating head injuries. While occurrence is rare, diagnosis can be made in the emergency department. Described in the present report is the case of a 26-year-old man who presented with complaints of pain, redness, blurred and loss of vision in the right eye, and swelling of the upper face due to a gunshot injury he had sustained 35 days prior.

The Effect of Systemic and Regional Use of Magnesium Sulfate on Postoperative Tramadol Consumption in Lumbar Disc Surgery.

AIM: To investigate the effect of magnesium administered to the operative region muscle and administered systemically on postoperative analgesia consumption after lumbar disc surgery. MATERIAL AND METHOD: The study included a total of 75 ASA I-II patients aged 18-65 years. The patients were randomly allocated into 1 of 3 groups of 25: the Intravenous (IV) Group, the Intramuscular (IM) Group, and the Control (C) Group. At the stage of suturing the surgical incision site, the IV Group received 50 mg/kg MgSO4 intravenously in 150 mL saline within 30 mins. In the IM Group, 50 mg/kg MgSO4 in 30 mL saline was injected intramuscularly into the paraspinal muscles. In Group C, 30 mL saline was injected intramuscularly into the paraspinal muscles. After operation patients in all 3 groups were given 100 mg tramadol and 10 mg metoclopramide and tramadol solution was started intravenously through a patient-controlled analgesia device. Hemodynamic changes, demographic data, duration of anesthesia and surgery, pain scores (NRS), the Ramsay sedation score (RSS), the amount of analgesia consumed, nausea- vomiting, and potential side effects were recorded. RESULTS: No difference was observed between the groups. Nausea and vomiting side effects occurred at a rate of 36% in Group C, which was a significantly higher rate compared to the other groups (p < 0.05). Tramadol consumption in the IM Group was found to be significantly lower than in the other groups (p < 0.05). CONCLUSION: Magnesium applied to the operative region was found to be more effective on postoperative analgesia than systemically administered magnesium.

Trigeminal Neuralgia as an Unusual Isolated Symptom of Pituitary Adenoma: Case Report and Review of the Literature.

Pituitary adenomas account for approximately 10% of intracranial tumors and 5% are locally invasive. Cavernous sinus invasion by pituitary tumors presents mostly with cranial nerve palsies, especially involving the third, fourth and sixth cranial nerves, which is well documented in the literature. However, an isolated complaint of trigeminal neuralgia due to pituitary adenoma is an extremely rare entity with a limited number of reported cases. A 51-year-old female patient presented to our clinic with complaints of pain and numbness on the left side of face for six months, with each event lasting 5-10 seconds. No improvement was obtained with administration of carbamazepine therapy. Magnetic resonance imaging of the sellar region revealed a mass with the left cavernous sinus invasion. The patient underwent surgery via endoscopic transsphenoidal approach and after than radiosurgery with gamma-knife. The patient's complaints resolved totally after gamma-knife radiosurgery. We report herein a case of pituitary adenoma with an isolated complaint of trigeminal neuralgia. Pituitary adenomas may be presented with cavernous sinus invasion and multiple cranial nerve palsies but isolated trigeminal neuralgia due to pituitary adenoma is an extremely rare entity.

Nonfunctioning Pituitary Adenomas Are Really Clinically Nonfunctioning? Clinical and Endocrinological Symptoms and Outcomes with Endoscopic Endonasal Treatment.

BACKGROUND: Nonfunctioning pituitary adenomas are the most common pituitary adenomas in adults and cause significant morbidity unless adequately treated. METHODS: This study retrospectively assessed the medical records of 160 patients operated via pure endonasal endoscopy. The presenting symptoms, results of neurologic and visual examinations, levels of pituitary hormones, results of radiologic examinations, size of the adenoma, rates of resection, results of postoperative visual examination, and pituitary hormone levels at follow-up were recorded to establish the appropriate approach, operative criteria, and outcomes of patients with nonfunctioning pituitary adenoma. RESULTS: Headache was the presenting symptom in 87.5% of the patients. Thirty-three percent had visual loss, and visual examinations on the whole study population revealed a visual field defect in 47.5% of the patients. Only 16.25% of the patients presented with endocrinological symptoms; 52.5% had abnormal anterior pituitary hormone levels. Regarding adenoma size, 56 patients had macroadenoma (35%), 84 (52.5%) had mesoadenoma, and 20 patients had giant adenoma. Gross total resection was achieved in 90% of the patients; subtotal resection was achieved in the remainder. The rate of total resection was lower for giant adenomas and recurrences. Visual symptoms and anterior pituitary hormone levels improved in 27 and 42 patients, respectively, after the operation. CONCLUSIONS: Nonfunctioning pituitary adenomas present frequently as mesoademonas and giant adenomas. Patients with these tumors may have subclinical visual or hormonal deficits at the time of diagnosis. Early and effective surgical treatment is essential for rapid recovery of visual and/or hormonal deficits, particularly in symptomatic cases.

Endoscopic Endonasal Transsphenoidal Pituitary Surgery: Experience of 80 Cases.

AIM: Surgical approaches to the pituitary have undergone numerous refinements over the last 100 years. The fully endoscopic transsphenoidal approach has gained widespread use all around the world. We report the results of a consecutive series of patients who underwent pituitary surgery using a pure endoscopic endonasal approach and the results of the evaluation of the efficacy and safety of this procedure. MATERIAL AND METHODS: We retrospectively reviewed the hospital database of 80 consecutive pituitary adenomas that were resected with the purely endoscopic endonasal transsphenoidal technique. RESULTS: The preoperative clinical condition of the patients, hormone profile, visual field, computed tomography and magnetic resonance imaging findings, and the Hardy-Vezina and Knosp scores were evaluated and revealed the importance of the parameters for surgery. Surgical technique, postoperative clinical condition of the patients, hormone profile, complications and follow-up period were reviewed. CONCUSION: Endonasal endoscopic pituitary surgery is a safe and effective surgical technique.

Use of Spongostan™ for Prevention of Cranial Subdural Adhesions Following Craniotomy in an Experimental Rabbit Model.

AIM: Spongostan™ is a sterile, water-insoluble, porcine gelatin absorbable sponge, which is widely used as a hemostatic material. The aim of this study is to test the anti-fibrotic capacity of Spongostan™, using a craniotomy model in an experimental rabbit model. MATERIAL AND METHODS: Eighteen rabbits were divided into two groups: Each group consisted of 9 rabbits, duratomy plus Spongostan™ (group 1), and duratomy without Spongostan™ (group 2). Right parietal bone was removed via trephine and low speed drill and dura was opened. On the group 1 rabbits, an appropriate piece of Spongostan™ was meticulously placed under dural layer. On group 2 rabbits, same procedures were repeated without Spongostan™. Histological sections were taken from each group and evaluated for degree of fibrosis and collagen fibers. RESULTS: There was marked increase in number of fibroblasts and collagen fibers in group 2 rabbits, however most of the rabbits in Spongostan™ group demonstrate scarce histopathological findings for fibrosis. CONCLUSION: We conclude that an appropriately placed subdural Spongostan™ over cerebral tissue may prevent postoperative surgical adhesions after neurosurgical operations.

Outcomes and demostration of cranial firearm injuries: A multicenter retrospective study.

BACKGROUND: Cranial firearm injuries (CFAI) are associated with significant morbidity and mortality.This study was aimed to determine the factors affecting mortality of CFAI cases managed in our institution by a retrospective analysis of CT scans and clinical data. METHODS: This multicenter retrospective study examined two hundred and nineteen patients presenting to neurosurgery clinics after CFAI between January 2012 and November 2014. Age, sex, Glasgow Coma Score (GCS), CT findings, and mortality and morbidity rates of the patients were analyzed to determine the factors affecting mortality. RESULTS: Mean age of the study population was 24.19±12.25 years, 85.8% of them were male. The most common CT findings were fracture (100%), intracranial hemorrhage (61.2%), and an intracranially located foreign body (44.3%). A cranial operation was performed in 64.8% of the victims. Mean GCS on admission was 8±3.9, which increased in survivors (p<0.05). CONCLUSION: CFAIs are associated with increased mortality and morbidity. We determined that many factors affected morbidity and mortality rates, and patient age, presence of intracranial hemorrhage, GCS, and treatment protocols were significantly associated with mortality.

Anterior Herniation of Partially Calcified and Degenerated Cervical Disc Causing Dysphagia.

We report a rare case of anterior cervical disc herniation associated with dysphagia. A 32-year-old man presented with complaints of dysphagia and concomitant pain in the right arm resistant to conservative therapy. On physical examination with respect to the muscle strength, the right shoulder abduction and flexion of the forearm were 3/5. Lateral X-ray revealed calcified osteophytes at the anterior C4-5 level. Magnetic resonance imaging showed soft disc herniation involving the right C6 root at the C5-6 level and anterior herniation of the C4-5 cervical disc. Anterior discectomies for C4-5 and C5-6 levels stabilized and ameliorated the dysphagia and pain. Cervical disc herniation usually presents with radicular findings. However, dysphagia may be an uncommon presentation. Anterior cervical disc herniation should be considered in a patient presenting with dysphagia.

Pure Endoscopic Endonasal Clipping of an Incidental Anterior Communicating Artery Aneurysm.

Anterior communicating artery (AcoA) aneurysm is the most common form of intracranial aneurysm. It occurs rarely together with other intracranial lesion. Today, microsurgical techniques and endovascular methods are used in the treatment of these aneurysms. Endoscopic endonasal approach is a useful technique for midline lesions of the skull base and is underpinned with extensive experience. In this article, we present a 72-year-old female patient who underwent endoscopic endonasal transplanum-transtubercular surgery for tuberculum sellae meningioma followed by clipping of the incidental AcoA aneurysm. After complete removal of a tuberculum sellae meningioma via an endoscopic endonasal approach, an anterior and superior projected saccular AcoA aneurysm in the gyrus rectus area was totally clipped successfully via pure endoscopic endonasal transplanum-transtubercular approach, without any damage to parent arteries. The patient was discharged from the hospital within a short period of time without any postoperative complication. Endoscopic endonasal approach is a new paradigm in the treatment of aneurysm. Although this technique cannot be routinely used due to lack of experience, it is an effective and safe method in selected and anatomically appropriate cases. We believe that increased knowledge and experience will create successful results in this approach, and it can offer an alternative method for selected aneurysm cases.
