[When the cause of dyspnea is on larynx. Asthma of difficult control, resistant to treatment? Vocal cords dysfunction? or Both?].
Dyspnea is a symptom whose diagnosis requires the exclusion of other diseases with which it can be confused, such as asthma and a variety of pulmonary and heart diseases. Dyspnea originated in the larynx may occur due to obstruction by a tumor or other affections in situ, interfering the airway, such as: edema by infections or inflammatory processes, a traumatism, an abnormal movement of the larynx structures, such as the inappropriate or absent of the vocal cords or the laryngospasm. Severity of larynx dyspnea may be to mild to acute, risking the life. This paper reviews the normal laryngeal function and the anatomic, obstructive, and functional disorders that can lead to dyspnea. Some suggestions are also made to determine the cause and treat these diseases.
