Dyspnea originating from the larynx

The larynx is a critical anatomic region through which all incoming and outgoing air must pass. The fine, complex movements of this fascinating area of our respiratory tract are carefully coordinated using an orchestra of neurologic and musculoskeletal movements combined with proprioceptive, auditory, and cognitive inputs. Numerous infections and noninfectious conditions may structurally interfere with airflow, and many require intervention for resolution to take place. Other conditions involve abnormal movements of laryngeal structures, and some, but not all, are amenable to treatment. The foundation for accurate diagnosis of these laryngeal abnormalities is direct visualization of the larynx. It is imperative that physicians who treat patients with shortness of breath are familiar with the normal anatomy and function of the larynx to accurately diagnose these conditions and orchestrate their effective treatment.
