First tracheoscopy: Entering the cervical trachea with the 0° straight tracheoscope. No evidence of exophytic tumor growth. Subsequent intubation. Now perform esophagogastroscopy. Enter the stomach through the esophagus with the flexible gastroscope. The stomach shows a partially lifted gastric fold. No evidence of exophytic tumor growth. Retraction of the esophagoscope, no evidence of exophytic tumor growth in the esophagus. Now inspection of the hypopharynx and the piriform sinus on the right and left: No evidence of exophytic tumor growth. Now inspection of the larynx, lingual, laryngeal epiglottis, anterior commissure, posterior commissure, left and right vocal fold macroscopically unremarkable. Postcricoid region macroscopically unremarkable. Now inspection of the oral cavity. The previously described mass at the edge of the tongue is now visible on the right. Now place a holding suture, elevate the tongue to the left, cut around the mass in a circular fashion and extirpate it in toto. Samples are taken from the edges of the specimen in a clockwise direction and sent for processing. Marking of the remaining surgical specimen. Careful hemostasis is then performed again. Suturing of the wound edges. Ultrasound on <2008> showed several small lymph nodes up to 12 mm in diameter and hilar signs in the right tongue after PE. On the advice of <CLINICIAN_NAME>, a right neck dissection is currently being avoided. After receiving the definitive histology, a decision will be made about a right neck dissection. Conclusion: Panendoscopy and excision of a right tongue margin tumor.
