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

In our study, 66-year-old and 57-year-old women, both Chinese, were diagnosed with GRH presenting preoperatively definite imageology characters as pituitary adenoma. The 66-year-old woman presented with a year of headache, half a year of gradual decrease of visual acuity, and one month of right ptosis. Serum prolaetin level was slightly elevated. Screening computed tomography （CT） scanning revealed typical low density mass found on the enlarged sella, which demonstrated invasive extension from the sella to the right cavernous sinus by contrast enhanced magnetic resonance imaging （MRI）. Consequently, the patient was diagnosed with probable invasive pituitary adenoma. The other 57-year-old woman complained a light headache and had been previously treated as nonfunctional pituitary adenoma in other hospital. Finally these two patients underwent transsphenoidal microsurgery and were diagnosed with GRH according to postoperative histopathology. They then were treated with steroid. During the follow-up, the clinical symptoms such as headache, visual damage, and ptosis vanished, and the mass of the sellae dramatically shrank on repeated MR images. Clinically and radiologically, GRH is a rare sellar entity easily to be misdiagnosed as a pituitary adenoma. Trans-sphenoidal surgery can decompress the optical nerve or oculomotornerve as a therapeutic strategy, and support biopsy or further pathological diagnosis. However, the hormonal therapy should be emphasized both as diagnostic and therapeutic strategies. Conservative and tentative steroid treatment should be performed in preoperative period without acute nerve damage.展开更多
