Transfer of the patient to the operating theater and positioning of the patient. Consultation with the anesthesiologist. Start with inspection of the oral mucosa. This is non-irritating and inconspicuous. The tonsils and base of the tongue are also palpable and clinically unremarkable. The lateral and posterior walls of the pharynx are also unremarkable, as are the cricoid region and both piriform sinuses. The left vocal fold shows a whitish, exophytic mass over the entire length of the vocal fold. Reinke's edema can also be seen. The mass is carefully cut around with the CO2 laser. A swab on the tube protects the cuff, which remains intact. A sufficient safety margin was left anteriorly at the anterior commissure. If the patient is difficult to adjust, it is necessary to switch between the small bore tube C and D and to readjust the tumor several times. However, complete resection of the tumor is possible without any problems. Dorsally, the resection margin extends to the vocalis process, basally to the vocalis muscle. The vocalis muscle can be identified as tumor-free muscle tissue. There is no increased bleeding after resection. Now take 3 marginal samples. These are taken dorsally at the vocal process, basally at the vocalis muscle and caudally at the sedimentation margin or subglottic slope. Insertion of a suprarenal swab. All these marginal samples are tumor-free. Removal of the swab. If there is no bleeding, the operation is ended. Final consultation with the anesthesiologist. Conclusion: The patient has a cT1a glottic carcinoma of the left vocal fold. The final histology should be awaited, the marginal samples were clear today. A follow-up MLE is recommended in 8 weeks.
