Sinonasal endoscopy has brought radical changes in the concepts of pathophysiology and treatment of sinonasal aliments as well as surgical techniques. <strong>Aim of the Study:</strong> To compare between the use of endoscopic and microscopic trans-sphenoidal approach in resection of growth hormone-secreting pituitary adenomas with Suprasellar Extension. <strong>Patients and Methods:</strong> This is a prospective study. It had been conducted upon 20 patients having growth hormone secreting pituitary adenoma admitted to Neurosurgery department in Alzar University hospitals and Nasr City Insurance hospital from 2015 to 2018, divided into 2 groups;group A (10 cases) underwent endoscopic endonasal trans-sphenoidal pituitary adenoma resection, while group B (10 cases) operated upon using the standard microscopic trans-sphenoidal pituitary adenoma resection. The inclusion criteria were included: All patients with growth hormone secreting pituitary adenomas showing manifestations of acromegaly, mass effect or hormonal disturbance. <strong>Results:</strong> This study showed that improvement in outcome was higher in endoscopic group opposed to microscopic group (100% vs. 71% improved headache, 80% vs. 60% visual improvement, 75% vs. 20% fundus improvement and 60% vs. 30% field improvement).<strong> Conclusion:</strong> We concluded that fully endoscopic procedure result in improved rates of complete tumor removal and a reduced incidence of complications, when compared to the microscopic approach.展开更多

Methods: A comparative descriptive study, involved 117 patients suffering from lumbar canal stenosis, aged between 40 - 70 years;admitted to department of Neurosurgery from March 2011 till august 2016 in King Fahad Hospital in Saudi Arabia. Study groups are consisted of group A as patients managed with classical laminectomy, group B as patients managed with endoscopic spinal procedures and group C as patients managed with microscopic decompression facilitated by the Metrex Tubular System. SPSS was used in data entry and analysis, and ethical considerations taken into consideration and participants filled the required inform consents. Results: Age of particaoncet ranged from 45 - 63 years, Mean +/‒50. The degenerative canal stenosis with acute disc single level (cauda equina syndrome) was the most common type of lumbar canal stenosis encountered in group A;the unilateral foraminal and lateral recess stenosis without disc prolapse was the most common type of lumbar canal stenosis encountered in group B;while the unilateral foraminal and lateral recess stenosis without disc prolapse was the most common type of lumbar canal stenosis encountered in group C. Classic laminectomy and disectomy used mostly in group A;endoscopic unilateral decompression lamino-foraminotomy without discectomy used mostly in group B and bilateral microscopic laminectomy without discectomy followed by unilateral microscopic laminoforaminotomy without discectomy used mostly in group C. Mean of operation duration was the highest in both gender of group A, followed by group B, then group C. Unintended durotomy was the most common intra operative complications occurred in the whole study especially in group A. Mean of blood lost was the highest in both gender of group A, followed by group B, then group C. Postop complications in the patients of study groups were the highest in group A (33.3%), followed by group B (8.5%) and then group C (2%). Conclusion: Microscopic decompression facilitated by the Metrex Tubular System is the most effective technique of Surgery for Lumbar Spinal Stenosis and the least intra-operative and post-operative complications.展开更多

Methods: This random control study included 63 patients (63 eyes) with primary pterygium. These were randomly divided into a group with corneal limbal conjunctival autograft combined with pterygium excision (group A) and a group with pterygium excision with exposed sclera (group B) and subjected to long-term follow up. The surgical outcomes were classified and evaluated (grade Ⅰ-Ⅳ). Several indexes were analyzed, including ocular surface irritation symptom,tear film stability, surgical complication, and recurrence rate. Results: The follow up ranged from 24 to 38 months, (26.9± 3.4) months on average. No recurrence was noted at 6 weeks postoperatively. At 6 months postoperatively, the recurrence rate of pterygium was 5.2% in group A and 8.0% in group B. At 1 year postoperatively, the recurrence rate in group A was 10.5% and 20.0% in group B. At the end of follow up, the recurrence rates were 13.1% in group A and 24.0% in group B. No statistical significance was found between two groups regarding the recurrence rates at each time point (P>0.05). After the follow up. (> 2 years),the severity of ocular surface conditions was significantly milder in patients in group A than in group B (P <0.01).No statistically significant differences were noted between the two groups at 6 weeks,6 months, and 1 year after surgery. No statistically significant differences were observed between the two groups regarding postoperative tear film break-up time. Fewer postoperative complications and milder ocular surface irritation symptoms occurred in patients in group A. Conclusion: Corneal limbal conjunctival autograft combined with pterygium excision yields sound long-term efficacy and a low recurrence rate and induces only mild damage on the ocular surface when used as a treatment for pterygium.展开更多

Results: Surgeries were performed in a very clear field under microscope. Wesuccessfully did vascular microdissection and ACV preservation. Also with the use ofmicroscope, various kinds of strabismus microsurgery videos were recorded.Conclusions: Microscopic technique can be used to enhance the quality and accuracy ofstrabismus surgery and to reduce surgical damage, postoperative inflammatory reactionand scar formation. All kinds of strabismus surgery , especially, oblique muscles andcomplex paralytic operations can be performed under microscope.展开更多
