Objective: The purpose of this paper is to solve certain problems with the treatment of early glottic and laryngeal carcinoma with cryoablation under a laryngoscope. 

Methods: A total of 88 patients with early glottic laryngeal cancer T0–T1 treated in our hospital from January 2016 to October 2020 were taken as the research object. Among them, 86 were male and 2 were female, aged from 35 to 99 years old. None of the patients needed radiotherapy or chemotherapy after the operation. They all underwent CO₂ laser surgical resection with a supporting laryngoscope microscope. All patients were followed up regularly for five years after discharge and the treatment results were analysed and studied.

Results: The results of the study show that the use of supporting laryngoscope microscope CO₂ laser surgery for early (T0–T1) portal larynx cancer resection can improve the treatment effect by 75%, raise the patient recovery rate to 100%, the tumour removal rate to 95.8%, the patient survival rate to 98.8% (only one person died) and lower the recurrence rate to only 7.9%.

Conclusion: These data prove the feasibility and superiority of supporting laryngoscope microscope CO₂ laser surgical resection in the treatment of early-stage laryngeal carcinoma.
