RESUMEN

Objective@#To investigate the feasibility of using a carbon dioxide(CO2) laser in the treatment of facial papilloma in children and to evaluate its curative effect and prognosis.@*Methods @#A case of pediatric facial papilloma treated with a CO2 laser was reported, and the effects of this disease and CO2 laser treatment were reviewed and analyzed in combination with the literature. @* Results@#Under general anesthesia, the lesion tissue of the left lip was excised for pathological biopsy, and the diagnosis was maxillofacial papilloma. The lesions were surgically ablated in stages with a CO2 laser, and erythromycin ointment was applied to the surgical incision after surgery. A total of three rounds of CO2 laser treatment were performed for 3 treatment courses. The child had no complications during or after the operation, the facial appearance was significantly improved, and there was no sign of recurrence during the 6-month follow-up. A literature review showed that CO2 lasers have been widely used in the excision of various surface lesions. In clinical practice, continuous CO2 laser with power of 10-50 W and wavelength of 10.6 μm is used to treat superficial tissue lesions, which can achieve accurate vaporization resection of diseased tissue, less bleeding and a good prognosis.@* Conclusion@#CO2 laser was accurate and minimally invasive for the removal of facial papilloma in children.

RESUMEN

@#Oropharyngeal carcinoma is a highly heterogeneous disease that is mainly caused by tobacco and alcohol abuse or high-risk human papillomavirus (HPV) infection. HPV-positive oropharyngeal carcinoma and HPV-negative oropharyngeal carcinoma have obvious differences in etiology, epidemiology and prognosis; therefore, different methods should be adopted for treatment. It is known that the TP53 gene is not mutated in HPV-positive oropharyngeal carcinoma, and radiation therapy can activate it and induce cell apoptosis via DNA damage. There are common repair pathways to DNA damage, such as nonhomologous end joining, and this pathway is more sensitive to radiotherapy under the inhibition of HPV oncoprotein. In addition, the further activation of the immune response under the effect of radiation also participates in the elimination of tumors. In this paper, we reviewed the research on the sensitivity of HPV-positive oropharyngeal cancer to radiotherapy to provide a scientific basis for targeted treatment for various pathogenic factors and clinical stages of oropharyngeal cancer in the future.
