Clinical effects of minimally invasive CO₂ laser surgery for laryngeal carcinoma

Objective To explore the clinical effects of minimally invasive CO₂ laser surgery under a laryngoscope in the treatment of laryngeal carcinoma. Methods A retrospective analysis was performed using data from 45 patients with laryngeal carcinoma from January 2016 to April 2018. There were 20 patients receiving minimally invasive CO₂ laser surgery and 25 patients undergoing traditional open operation. Both groups were compared for the operation time, the volume of blood loss, Visual Analogue Scale(VAS), hospitalization stay and costs. Results Patients in stages T1 and T2 undergoing minimally invasive CO₂ laser surgery showed shorter operation time and hospitalization stay, as well as less volumes of blood loss, VAS score, and hospitalization costs than those receiving traditional open operation (P<0.05). Conclusions Minimally invasive CO₂ laser surgery under a laryngoscope is more effective than the traditional open operation in the treatment of laryngeal carcinoma at T1/T2 stage.
