Introduction: We describe the surgical technique for the resection of laryngeal carcinomas using microelectrodes (MEs), and also report our oncologic and functional results.
Material and method: Retrospective study of 83 patients with T1, T2 or T3 glottic and supraglottic carcinoma and operated using MEs.The following parameters were compiled: tumor location, TNM stage, age, gender, tracheostomy, neck dissections, requirement of nasogastric feeding, duration of hospital stay, time of decannulation, recurrences and metastases.
Results: Eight patients required tracheostomy. Nasogastric feeding was indicated in eight cases. The duration of hosspital stay ranged from 1 to 20 days post-operatively (median, 2.9 days). The length of follow-up ranged from 6 to 60 months. There were seven cases with local recurrences (8.5%). Three patients required total laryngectomy as second operation procedure. Three patients had a second laryngeal tumor after two years of evolution (3.6%).
Conclusions: All tumors that are resectable with a CO2 laser can be resected with MEs, with the following advantages: shorter operating time; improved hemostasis; cutting in angle is possible; the sense of “touch” with MEs is direct and real through the instrument; excellent visualization with full lighting by the operating microscope; easier handling of instruments; and lower equipment costs.
