Pediatric laryngeal papilloma has been an extremely difficult disease to treat, despite being essentially a benign lesion, because of its unique location and the high risk of recurrence after excision. There is even a risk of life-threatening spread. So far, no method has been found to effectively control or eliminate human papillomavirus. The main reason for this is that it is not possible to control or eliminate human papilloma virus. In addition to its antiviral effects, interferon “also has a role in regulating the immunity of the body”, probably by enhancing the expression of protein kinases and nucleic acid endonucleases that inhibit viral protein synthesis to regulate the host immune response. The therapeutic effect of measles vaccine may be due to factors other than the enhancement of host immunity, such as the biological immune effect, which may be due to the symbiosis of the two viruses, resulting in mutual inhibition and interference, which is not present in the other two drugs. In addition, new therapeutic drugs have emerged in recent years, and research on human papillomavirus vaccines have all made great progress. Some studies have shown that pidomod has a beneficial effect on enhancing immunity and reducing recurrence in children with laryngeal papilloma.
