After positioning the patient, re-inspection of the tumor with the small bore tube: The above-described, partially exophytic, spherical mass in the area of the right base of the tongue is seen. Insertion of the Olympus mouth retractor. This is achieved with difficulty so that the tumor can be exposed here. It can be seen that the tumor has spread from the base of the tongue to the glossotonsillar groove and the caudal tonsillar pole. Docking of the robotic system. Start of resection in the area of the base of the tongue and the lateral pharyngeal wall at the caudal tonsil pole. From here, resection caudally to the base of the tongue. The tumor is cut around here with a large safety margin. The resection just reaches the entrance to the vallecula. The tumor can be completely removed macroscopically in healthy tissue. Careful hemostasis is then performed. The suture is marked on the specimen. The specimen is sent for frozen section diagnostics. All margin samples and suture markings are found to be tumor-free. However, the marginal sample from the caudal margin is only just in sano, which is why a resection of about 1/2 cm is carried out into the base of the tongue and also caudally into the vallecula at the base of the lingual epiglottis. Here too, another marginal sample is taken, which is sent back for frozen section diagnostics and is clearly diagnosed as tumor-free. Repeated careful hemostasis. If the wound is absolutely dry and the patient can be intubated very well, the patient is not tracheotomized. The patient is transferred to the in-house intensive care unit for monitoring and should remain there over the weekend. The procedure was completed after further bleeding control. Further procedure: Planning of right neck dissection in the near future.
