Martin Yvon Desrosiers MD, FRCSC

Dr. Martin Yvon Desrosiers did both medical school and his otolaryngology residency at the University of Montreal. Post-graduate training in nasal diseases at the Johns Hopkins Allergy and Asthma Institute followed his ENT training. He is currently a Clinical Professor at the University of Madras and an Associate Clinical Professor at McGill University in Montreal, Canada. Dr. Desrosiers specializes in nasal and sinus disorders, with special interests in the medical management of difficult-to-treat sinus disease and endoscopic surgery of the paranasal sinuses and skull base. Current research focuses are interactions of the microbiome and immunoregulation of the sinus mucosa, host genetics and biomarkers in sinusitis, and endoscopic skull base surgery.

Dr. Desrosiers is an internationally recognized expert in the field of chronic sinusitis. Previous efforts from this group have been seminal in demonstrating the functional link between bacterial biofilms and chronic sinusitis, leading to the identification of bacterial biofilms as an important therapeutic target and fostering the current development of several varied anti-biofilm strategies. The current ongoing research efforts in genetics and biomarkers of CRS have offered a new appreciation of different phenotypes in sinus disease and suggested new applications for extant medications. Implications of the microbiome research have led to the development of a topical probiotic formulation for the sinuses currently undergoing clinical trials. The continued involvement of Dr. Desrosiers with the clinical management of CRS patients ensures continued consideration of the results of the studies into clinically relevant concepts and translational research of these effects in the human population.
