Research at Cal Sinus

Our research efforts are directed towards better understanding of the causes and treatments of sinus disorders. We are always working to develop safer and more effective treatment options for our patients.  We are known to work closely with new technologies and medical device companies (and their engineers) during their development and initial implementation phases.  We are also interested in elucidating the underlying etiology of chronic rhinosinusitis and developing treatments for the safer management of patients with chronic rhinosinusitis and other nasal / sinus problems.
