Induction of anesthesia and intubation by the anesthesia colleagues. Repositioning of the patient and insertion of the mouth guard. The right tonsil is then disluxed with the tonsil grasping forceps and the mucosa is incised over the upper tonsil pole with the conchotomy scissors. Locate the capsule and dissect it in depth. The findings are intraoperatively suspicious for a tumor. Careful bipolar coagulation and removal of the upper tonsil pole with the raspatory and conchotomy scissors. If the findings are suspicious for a tumor, perform a generous resection up to the pharyngeal muscles. Further dissection of the tonsil towards the lower tonsil pole. Generous resection 2 to 3 mm lateral to the resection margin. Bipolar coagulation at the lower tonsil pole and removal of the tonsil. The specimen is thread-marked for urgent histology. At this point, demonstration of the findings to <CLINICIAN_NAME> and termination of the procedure in dry conditions. The frozen section diagnosis unfortunately revealed R1, according to the pathology at the upper pole forming a margin, R1 anterolaterally and R0 resected at the lower tonsil pole with a 0.1 cm safety margin. Renewed demonstration of findings to <CLINICIAN_NAME>. He recommends no further resection in this session, but a resection with ipsilateral neck dissection with flap coverage if necessary. Conclusion: Tonsillectomy on the right, excision biopsy, which revealed a poorly differentiated squamous cell carcinoma. Unfortunately, no resection in healthy tissue as part of the tonsillectomy. Complete staging and planning of definitive therapy as part of a subsequent resection with or without flap coverage and neck dissection.
