Skull base neoplasm

This study tests giving chemotherapy and immunotherapy before standard surgery for head and neck cancer. The goal is to shrink tumors enough so that surgeons can perform less extensive, function-preserving operations, reducing damage to swallowing, speech, and vision. The trial e…

This study tests a special hydrogel (PuraGel) placed inside the nose after skull base surgery to see if it helps the surgical site heal faster and reduces pain. Thirty adults having this surgery will be randomly assigned to get either the hydrogel or a standard silicone splint. D…

This study compares two surgical tools—cautery and scalpel—used during endoscopic skull base surgery to see which better preserves a patient's sense of smell. 80 adults who need this surgery will be randomly assigned to one method. Their smell function will be tested before and a…

This study uses repeated MRI scans after radiation therapy to see if they can predict normal tissue damage, like bone death (osteoradionecrosis), in patients with oral cavity or skull base tumors. Researchers will track changes in imaging over time and link them to radiation dose…

This study is observing 120 patients with sinonasal or skull-base tumours at a specialist ear, nose, and throat centre. Researchers are tracking how these conditions are managed, what the outcomes are, and how patients' quality of life changes. The goal is to better understand cu…

This study follows 300 people treated for sinonasal, nasopharyngeal, or skull base tumors to track their symptoms and functional changes over time. Participants will complete symptom questionnaires and undergo standard tests like hearing, eye, and speech exams. The goal is to lea…

This study is gathering information from 4500 people who have or will have brain surgery for conditions like aneurysms, tumors, epilepsy, and Parkinson's disease. The goal is to find patterns that help doctors predict how well someone will recover. By standardizing how outcomes a…

This study uses a special MRI technique called diffusion tensor imaging to map cranial nerves before skull base tumor surgery. Researchers will compare the nerve positions seen on MRI with what surgeons actually find during the operation. The goal is to see if this imaging can he…

This study collects and analyzes tumor samples from 4000 people with skull base tumors. Researchers will study the genetic and molecular makeup of these tumors to learn how they form and resist treatment. The goal is to identify new targets for future therapies.
