Papilloma of the larynx is caused by infection with the papillomavirus (HPV for short), which has more than 60 subtypes, including HPV subtypes 6, 11, 16, 18, 31, 33, 35, 39, 42, 43, 44, 45, 51, 52, 56, 58, 59, and 68. There are differences in the HPV subtypes infecting children and adults with laryngeal papilloma, and the ease of treatment is different. Children’s laryngeal papilloma is caused by HPV subtypes such as 6 and 11, and is not usually cancerous. However, children’s larynxes are very small, and there is limited space for surgical operation, so it is difficult to completely remove the papilloma at one time, so children’s papilloma recurs, and many children have more than 10 surgeries. Surgical removal of laryngeal papilloma in children: Because of the small laryngeal cavity in children, most children with laryngeal papilloma full of vocal cords or laryngeal cavity at the time of consultation, and with varying degrees of respiratory difficulties, it is not appropriate to use CO2 laser to remove papilloma, but to use suction cutter to remove papilloma. Once bleeding occurs, it is difficult to see the papilloma, and if there is residue, it will definitely recur. Adult laryngeal papilloma Adult laryngeal papilloma is caused by HPV 16, 18, 33 and other subtypes (high-risk papilloma virus, which can cause cancer), and is also prone to recurrence, and some patients have experienced 5 to 6 surgeries. However, in adults, the laryngeal cavity is large and there is more room for surgical manipulation, making it easier to completely remove papillomas during surgery compared to children. In adults with recurrent laryngeal papillomas, there is a risk of cancer. In adults, the laryngeal cavity is large and well exposed, so laryngeal papilloma surgery is relatively easy, and the papilloma can be removed by CO2 laser. The smaller the laryngeal papilloma, the easier it is to remove it completely. The smaller the papilloma, the easier it is to remove it completely. Prevent vocal cord adhesions.
