Background: Though both anterior and posterior approach are used for the management of multilevel cervical spondylotic myelopathy (CSM), the choice between both approaches remains to be of considerable debate. Aim of the work: The aim of the study was to evaluate the clinical and radiographic outcomes of patients with multiple level CSM who underwent posterior laminectomy (PL) versus anterior cervical discectomy and fusion (ACDF). Methods: This is a retrospective comparative study of 30 patients, with multiple level CSM managed by the authors, either by PL (n = 15) or ACDF (n = 15). Clinical outcome was assessed at 1, 3, 6, and 12 months postoperatively using the modified Japanese Orthopedic Association scale (mJOA) while the postoperative radiographic changes represented by the Cobb's angle variation was recorded at 12 months postoperatively and compared with preoperative values. Also, the incidence of postoperative complications and neurological deterioration was recorded and studied between the two groups. Study duration was for 2 years from December 2014 to December 2016. Results: Both the ACDF and PL groups showed an improvement in the mJOA score mean value at 1 year after surgery in comparison with the preoperative evaluation data; however, on comparing between both groups at 1 year postoperatively, the median percent of increase in mJOA score was significantly higher in the ACDF group compared with the PL group (33.3% vs 22.2% respectively). On the other hand, the Cobb's angle percent of change 1 year after surgery showed a median percent of increase of 18.7% in the ACDF group in contrast to a median decrease of − 11.1% in the PL group which was statistically significant. Minimal complications were reported in both groups. Conclusion: Both PL and ACDF are effective modalities for the surgical management of multilevel CSM showing good clinical outcome; however, when compared with the posterior approach, there was a statistical significant difference favoring ACDF regarding the median percent of increase in mJOA score and the postoperative Cobb's angle improvement.

Background Symptomatic chronic subdural hematomas (CSDH) remain one of the most encountered forms of intracranial hemorrhages particularly in the elder patients, yet fortunately implies a good surgical prognosis. Burr hole evacuation under general anesthesia is the most commonly used neurosurgical technique for the management of CSDH. Clinical disagreement between many studies regarding the number of burr holes required to achieve the optimal surgical and clinical outcome has long existed. The objective of this study is to evaluate the prognosis and clinical outcome following the use of single-burr hole craniostomy technique in the aim of surgical evacuation of CSDH. Results This is a retrospective study of 30 patients, with symptomatic unilateral or bilateral CSDH managed by the authors strictly by single-burr hole evacuation with closed-system drainage on the corresponding site of the hematoma. Clinical outcome was then assessed at 1, 7, and 30 days after surgery using the Glasgow Coma Scale (GCS) and by comparing the Markwalder grade scale before surgery to 1 month following surgery; the pre- and post-operative radiological data, clinical neurological progress and the possible incidence of complications postoperatively were also recorded. Study duration was from August 2019 to October 2020. Our study included 18 (60%) male patients and 12 (40%) female patients. The main presenting symptom was altered level of consciousness noted in 29 (96.7%) patients; a history of a relevant head trauma was recorded in 11 patients (36.7%). The GCS showed a statistically highly significant improvement comparing the preoperative to the postoperative values throughout the follow-up intervals (p = 0.001); similarly, the Markwalder score significantly improved 1 month after surgery, where 17 (63%) patients were Markwalder grade 0, 9(33.3%) patients were grade 1, a single patient (3.7%) was grade 2, and none were Markwalder grade 3. Conclusion Our study concluded that single-burr hole craniostomy with closed-system drainage for the management of symptomatic CSDH would be a sufficient approach to achieve a good surgical outcome with a low complication rate. Larger series and further studies would be yet considered with longer follow-up periods.

Background: Patients diagnosed with pituitary apoplexy and presenting with acute visual deterioration require urgent surgical resection. This is also commonly associated with pituitary hypopituitarism that requires hormonal replacement for correction. This study was undertaken to evaluate the clinical recovery of 45 patients diagnosed with symptomatic pituitary apoplexy who underwent early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection with an emphasis on visual, ocular craniopathy, and endocrinological outcome. Methods: This is a retrospective analysis of a consecutive series of patients diagnosed with pituitary apoplexy between 2011 and 2020 treated by early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection. All tumors were histologically proven as pituitary adenomas. Clinical and neuro-ophthalmological examinations, imaging studies, and endocrinological evaluation were retrospectively reviewed. Patients with a minimum of 6 months follow-up were included in the study. The influence of patients’ demographics, extent of visual and ocular motility impairment, preoperative endocrinological dysfunction, tumor size and extent, degree of resection, and surgical complications were analyzed as potential prognostic factors for recovery. Results: Forty-five patients were included in this retrospective study. Ages ranged from 27 to 57 years (mean: 42 years). All patients presented with headache and variable degrees of visual loss and visual field deficit. Ophthalmoplegia was present in 22 (48.9%) patients with 17 (37.8%) having bilateral ocular cranial nerve palsy. All patients had variable degrees of endocrinological deficiencies. All patients showed evidence of low cortisol, 14 (31.1%) showed hypothyroidism and 11 (24.4%) showed hypogonadism. There was evidence of hyperprolactinemia in 16 (35.6%) patients. All patients harbored a pituitary macroadenoma. Tumor resection was complete in 33 (73%) of patients, with residual tumor related to cavernous sinus or retrosellar extension. Operative complications were mainly related to short-term nasal complications occurring in 14 (31%) patients. Cerebrospinal fluid leak requiring revision surgery occurred in only one patient harboring a modified SIPAP Grade 3s tumor. Transient diabetes insipidus occurred in 9 (20%) patients, with 2 (4.4%) requiring long-term hormonal replacement. The mean follow-up was 25 months. Baseline visual improvement was achieved in 39 (86.7%) patients. Ocular cranial nerve palsy showed complete recovery in 17 (77.2%) patients. Endocrine follow-up showed that patients with panhypopituitarism (11 [24.4%]) failed to recover. Conclusion: The current surgical series showed safety in terms of low complication rate and efficacy in terms of clinical outcome. The significant prognostic factor related to visual recovery was the degree of preoperative visual deficit. Recovery of ocular cranial neuropathy showed a higher recovery rate when it was unilateral as opposed to bilateral. Pituitary hormonal recovery was less favorable with pituitary panhypopituitarism being a poor prognostic factor.

Background: Lumbar interbody fusion procedure is a recognized surgical technique in management of a variety of lumbar pathologies including recurrent lumbar disc prolapse. Interbody fusion augmented by pedicle screw fixation has been considered to improve fusion rates and clinical outcomes. Interbody fusion is commonly associated with better fusion potentials through applying the bone graft in the load bearing, vascular position of the anterior, and middle spinal columns. However, it still remains unknown whether interbody fusion with unilateral pedicle screw fixation (UPSF) is superior to that with bilateral pedicle screw fixation (BPSF). Aim of the work: The aim of this study is to evaluate the efficacy and safety of unilateral versus bilateral pedicle screw fixation associated with interbody fusion for the management of single level unilateral recurrent lumbar disc prolapse as regard the clinical and biomechanical results, operation time, intraoperative blood loss, and postoperative stay. Material and methods: This observational prospective comparative study of the two groups who were operated either unilateral (group A /15 patients) or bilateral (group B/15 patients) pedicle screw fixation with interbody fusion was done. Patients were followed up for 1, 6, ad 12 months. Results: Significant improvement in functional outcome of the two groups was noted compared to preoperatively, except in early postoperative period where the back VAS and ODI in the unilateral group was better than bilateral group. However, on further follow up, no significant difference was noticed. There was no significant difference comparing fusion rate, complication rate, and duration of hospital stay between the two groups at postoperative follow-up. There was significantly less blood loss, and significantly shorter operation time in the unilateral PS fixation group as compared with the bilateral PS fixation group in our study. Conclusion: Our study suggested that TLIF with unilateral PS fixation was as safe and effective as that with bilateral PS fixation for the management of recurrent single level lumbar disc prolapse; it showed better clinical outcome scores of ODI and back VAS, and a significant reduction of the intraoperative blood loss as well as the operation time, without significant differences considering fusion rate, complication rate, and duration of hospital stay between the two groups at postoperative follow-up. However, BPSF with TLIF likely causes more degeneration at the cranial adjacent segment compared with UPSF techniques. Nevertheless, the long-term follow up is required to demonstrate the impact of these findings.

Background Chronic subdural hematoma (CSDH) is a commonly encountered neurosurgical entity, particularly among the elderly population. Surgical intervention by trepanation or burr hole craniostomy remains the gold standard approach for symptomatic cases. However, despite the excellent outcome, the surgical pathway remains also associated with possible complications, some of which might be fatal, in addition to a recurrence rate of up to 25%. Dexamethasone (DXM) therapy was used as an alternative non-surgical approach, yet its clinical effectiveness remains controversial. Therefore, the objective of this study is to evaluate the outcome of DXM use for the management of chronic subdural hematomas with regard to the clinical results, safety, efficacy and potential incidence of complications. Results This is a retrospective study of 30 patients, with symptomatic CSDH managed by the authors by DXM therapy protocol. Subjects were assessed upon admission then closely monitored to evaluate their response to conservative management, then followed up and their data were recorded at 2 weeks, 1 month, 3 months, and 6 months after protocol initiation. Clinical scoring systems included the Glasgow Coma Scale (GCS) and the Markwalder Grading Scale (MGS), whereas radiological evaluation consisted of serial Computerized tomography (CT)scans to assess CSDH changes between time of protocol initiation and over the same time intervals. There was a statistically highly significant improvement regarding the GCS and the MGS of the studied cases on comparing the starting values to those throughout the follow-up intervals at 2 weeks, 1 month, 3 months, or six months (p = 0.001). Patients presented with a neurological deficit also showed a statistically highly significant improvement on comparing the values at the beginning of our study to those recorded at the third month or those at the sixth month (p = 0.001). Conclusions Our study concluded that dexamethasone use is a safe and effective choice for the management of chronic subdural hematoma with an acceptable success rate and a low incidence rate of serious complications. We do not advocate for the replacement of surgery by DXM treatment but to consider its possible role in selected cases. Larger series and further studies would be yet considered with longer follow-up periods.
