Background

Nicholas Rowan is a sinus and skull base surgeon who helps patients with conditions such as deviated septum, nasal congestion, nasal obstruction, sinus pressure and chronic sinusitis, as well as complex issues like loss of smell, sinus cancers, cerebrospinal fluid (CSF) leaks and tumors that grow near the brain.

He frequently performs nasal polyp surgery and endoscopic sinus procedures, using minimally invasive approaches to help patients recover quickly and breathe more easily. For tumors of the skull base or brain, he works closely with neurosurgeons and cancer specialists to deliver coordinated, comprehensive care.

Dr. Rowan’s research is focused on improving patients’ quality of life and long-term outcomes after sinus and skull base surgery. A major part of his work involves studying the sense of smell — not just how to restore it, but how it reflects overall health. He explores how smell loss may be an early warning sign of unhealthy aging, frailty or cognitive decline. Through this work, he aims to better understand the biological link between the nose and brain, and what it can reveal about a person’s health trajectory. He works closely with biomedical engineers to develop novel diagnostic and therapeutic technologies, and he is the principal investigator of multiple ongoing clinical trials that are testing new treatments for chronic sinusitis and nasal polyps.

A frequent speaker at national and international conferences, Dr. Rowan shares insights from his innovative research and surgical experience. He leads courses and delivers lectures on advanced sinus and skull base techniques, smell loss and the evolving science behind how nasal health connects to overall well-being.

Nicholas Rowan Lab  

The Rowan Lab is actively engaged in both outcomes and translational research focused on the sense of smell, chronic rhinosinusitis and endoscopic skull base surgery. A primary emphasis is on how the sense of smell changes with age. The lab also explores patient-reported quality of life measures, particularly those related to brain tumors and smell. Dr. Rowan leads clinical trials investigating new medical treatments and innovative technologies to improve care for patients with chronic rhinosinusitis, including ongoing drug trials evaluating novel therapies for this condition.

Research Summary

Dr. Rowan’s research focuses on improving the understanding and treatment of chronic rhinosinusitis and disorders of the sense of smell. In addition to studying changes in the sense of smell, he investigates how these changes may serve as early warning signs of broader health problems. His work also emphasizes improving patient quality of life and surgical outcomes. Additionally, Dr. Rowan has contributed to multiple patents for novel therapies designed to restore smell and treat sinus conditions.
