Therapeutic effects of low-temperature plasma radiofrequency ablation and partial laryngectomy for glottis cancer: A comparative study.

OBJECTIVE

To compare the therapeutic effects of low-temperature plasma radiofrequency ablation and partial laryngectomy in the treatment of early glottis carcinoma.

METHODS

Clinical data of 80 patients with early glottis carcinoma treated in our hospital from June 2019 to January 2021 were analyzed. Patients were retrospectively divided into two groups based on the type of intervention. Forty patients received partial laryngectomy (Control group) and 40 patients received low-temperature plasma radiofrequency ablation (Observation group). Surgical indexes, length of hospital stay, postoperative complications, and visual analog scale (VAS) score of postoperative pain of patients in the two groups were compared. Postoperative stress response indexes, clinical efficacy, and postoperative recovery in two groups were compared and analyzed.

RESULT: The operation time, hospital stay, intraoperative bleeding, and the incidence of postoperative complications in the observation group were significantly lower than those in the Control group (P<0.05). The postoperative pain VAS scores, Levels of malondialdehyde (MDA) and glutathione (GSH) in the observation group were significantly lower than those in the control group (P<0.05), while the level of nitro tyrosine (3-NT) and superoxide dismutase (SOD) were significantly higher than that in the control group (P<0.05). After a one-year follow-up, the excellent and good rate of pronunciation function in the observation group (95%) was significantly higher than control group (75%) (P<0.05).

CONCLUSIONS

Low-temperature plasma radiofrequency ablation in the treatment of early glottis carcinoma is associated with less trauma, short operation time, less bleeding, short hospital stay and low postoperative stress reaction rate. Compared with partial laryngectomy, it has higher safety and better postoperative vocal cord function recovery.
