ENDOSCOPIC ENDONASAL SURGERY FOR TREATMENT NOSTRIL TUMORS INVADING INTO BRAIN
Main Article Content
Abstract
Objectives: Application of endoscopic surgery to dissect tumors of the anterior skull base. Materials and Methods: descriptive study with intervention. To investigate clinical symptoms, histology and describe the techniques of endoscopic surgery to remove the anterior skull base tumors at Ear Nose and Throat Department and Neurology Department of Cho Ray Hospital. Results: From Sept 2010 to Dec, 2018; 90 patients were examined and performed endoscopic surgery to remove tumors of the anterior skull base at ENT Department of Cho Ray Hospital. The most frequent maglignant tumors (60%) consist of squamous cell carcinoma (17,8%), adenocarcinoma (8,9%) and olfactory neuroblastoma (11,1%), while ossifying fibroma and meningioma was the most common benign tumors. Using endoscopic surgery, totally removal of anterior skull base tumors was performed successfully. Conclusion: The endoscopic endonasal approach to remove of tumors of anterior skull base is a minimal invasive technique , which has clear and direct visualization. In some circumstances, this technique can preserve the functions of the nose and paranasal sinuses.
