Objective:
Sinonasal tumors invading anterior skull base is difficult to treat in Otorhinolaryngology and Neurosurgery. Treatment requires the collaboration of ear, nose and throat (ENT) and neurosurgeon to remove the tumor completely. This study was to evaluate the outcome of combined technique nasal endoscopic and subfrontal approach in case of sinonasal tumors involving anterior skull base.
Methods:
Retrospective cross-sectional study.
Results:
The study was a cross-sectional study that had taken place at Otorhinolaryngology and Neurosurgery Department of Cho Ray Hospital, Vietnam. All 45 patients were enrolled and underwent the surgery. 71.1% of these cases were malignant tumors. The ratio of sinonasal malignant tumor is squamous cell carcinoma and esthesioneuroblastoma were 24.4% and 11.1%, respectively. All the cases were diagnosed as sinonasal tumor invading anterior skull base and successfully removed by combining nasal endoscopic approach with subfrontal craniotomy.
Conclusions:
The combined nasal endoscopic with subfrontal craniotomy for resection nasoethmoid tumor invading the brain show a good result. This technique is an important adjunct that contribute to the treatment of anterior skull base tumor involving the brain.
