The study demonstrates the high efficacy of FELS in treating T1-T2 glottic carcinoma, achieving a successful treatment rate of 88.3% with local control and larynx preservation. The advantages of the method include the ability to perform treatment under local anesthesia, avoiding general anesthesia and its associated risks.
Objective: Flexible endoscopic laser surgery (FELS) is able to overcome some limitations of traditional transoral CO2 laser surgery. The objective of this study was to assess the efficacy of FELS in the treatment of T1-T2 glottic carcinoma. Methods: We applied FELS for 120 patients with T1-T2 glottic carcinoma. Tumour ablation was performed with Nd:YAG laser. In 76 (63.3%) cases the intervention was performed under local anesthesia. Twenty nine (24.2%) patients (T1b -2, T2-27) underwent postoperative radiation therapy (RT). Results: Successful treatment, with local control and larynx preservation, was obtained in 106 cases (88.3%), with mean follow-up of 6.4 years. More than 50% of the patients were followed-up over 5 years. Conclusions: FELS can be proposed as an alternative treatment method for patients with early glottic carcinoma. The advantages of the method include: possibility of applying treatment under local anesthesia, that allows avoiding of general anesthesia and its related risks; applicability to patients with contraindications to general anesthesia and patients with anatomic particularities, that make transoral microsurgery impossible, allowing avoidance of the laryngofissure and tracheotomy.
