Mild accessory tracheal is a term that is not often used in medical circles. But in fact, such a disease exists and a number of clinical studies and scientific papers are devoted to it.
Adding the word “additional” may be a little confusing, but in fact it’s simple: if a person has a slight malfunction of the internal structures of the respiratory system, namely the lung or trachea (the tube that connects the larynx and bronchi), this disease is called lung accessory tracheal.
