The common causes of laryngeal voice during breathing include congenital diseases, inflammatory reactions in the airway, and laryngeal tumors. 1. Congenital diseases: for example, congenital laryngeal cartilage softening or congenital deformity of laryngeal bone, resulting in laryngeal stenosis, laryngeal voice phenomenon when breathing, and sometimes there will be cyanosis, respiratory distress and other symptoms of hypoxia, which is mostly found in infants and young children. 2. Inflammatory reaction of airway: for example, wheezing bronchitis, pharyngolaryngitis, bronchial asthma, etc. Due to the inflammation of airway mucosal edema, increased secretion, airway spasm, which results in the increase of airway resistance, there is the phenomenon of voice when breathing, and there are wheezing, shortness of breath and other symptoms. 3. Laryngeal tumors: benign tumors such as vocal polyps and vocal cysts can cause narrowing of the vocal folds, thus causing a voice when breathing; malignant tumors of the larynx such as laryngeal cancer can also cause narrowing of the vocal folds and airway, and the voice will also show the symptom of rumbling when breathing. There may be other reasons for the sound of voice when breathing, so it is recommended to go to regular hospitals in time for examination and treatment under the guidance of professional doctors.
