Summary
Microdissection electrodes (MEs) offer a cost-effective alternative for endoscopic cordectomies. While both MEs and CO2 lasers showed similar complication rates, ME use resulted in comparable voice outcomes for T1 glottic carcinoma patients.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Laryngeal Microsurgery
Background:
- Endoscopic cordectomy is a standard treatment for early glottic cancer.
- Microdissection electrodes (MEs) have emerged as a potential tool for these procedures.
- Comparison with the established CO2 laser technique is crucial.
Purpose of the Study:
- To prospectively compare the efficacy and safety of microdissection electrodes (MEs) versus CO2 laser for endoscopic cordectomies.
- To evaluate voice outcomes and complication rates between the two surgical devices.
Main Methods:
- A prospective study involving 40 patients with T1 glottic carcinoma.
- Patients were alternately assigned to undergo surgery with either CO2 laser or MEs.
- Outcomes assessed included glottic incompetence, web formation, granuloma, and dysphonia grade.
Main Results:
- No statistically significant differences in glottic incompetence or web formation between groups.
- One granuloma occurred in the CO2 laser group; no granulomas in the ME group.
- Dysphonia rates were high in both groups, with no significant difference based on surgical device.
Conclusions:
- Microdissection electrodes (MEs) are a viable, inexpensive alternative to CO2 laser for endoscopic cordectomy.
- Both techniques yield comparable complication profiles and voice outcomes in T1 glottic carcinoma.
- Further research may explore optimizing ME use for improved functional results.
