In the patient, a squamous cell carcinoma in the area of the base of the tongue on the left was histologically confirmed during a panendoscopy and assessed as cT1 in the panendoscopy. Due to dental artifacts, it was not possible to determine the exact extent of the tumor in CT diagnostics. No evidence of metastasis on sonography and computed tomography. In our interdisciplinary tumor conference, the primary surgical procedure was recommended and primary transoral resection was planned due to the initial extent of the tumor.
