Inflammation occurs in the laryngeal, tracheal and bronchial cartilages. The tumor infiltrates into infrahyoid muscles, trachea, oesophagus, recurrent laryngeal nerve, carotid sheath, etc. Recurrent laryngeal nerve resection involves removing a section of the recurrent laryngeal nerve. Its laryngeal surface faces into the larynx. Most laryngeal cancers originate in the glottis. For example, it can be attached to an endotracheal tube or laryngeal mask airway. Bilateral injury to the recurrent laryngeal nerve would cause this condition. One nerve is the recurrent laryngeal nerve, which becomes the inferior laryngeal nerve. The external branch of the superior laryngeal nerve innervates the cricothyroid muscle. Below the vocal folds it is by way of branches of the recurrent laryngeal nerve. The nerve of the fourth arch gives rise to the superior laryngeal nerve. Arches 4 and 6 produce the laryngeal cartilages. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis. Breathing difficulties can occur, resulting from neuromyotonic activity of the laryngeal muscles. In addition, the location and configuration of the laryngeal alar cartilage was described.
