Postnasal Drip

Understanding Post-Nasal Drainage: Insights from Rhinology and Laryngology ExpertsMost cases of post-nasal drainage are dismissed as benign or overlooked, but beneath the surface lies a complex, under-researched challenge affecting millions. In this eye-opening episode of Rhinology Roundtable, host Dr. Ashleigh Halderman pulls back the curtain on post-nasal drainage—a symptom that can feel like drowning in mucus despite normal exam findings. Joining her is renowned laryngologist Dr. Kathleen Tibbetts from Thomas Jefferson University, who reveals surprising insights that challenge conventional thinking.
