CO2 laser excision of oral cancer. Top left: patient presented with a multinodular lesion of the ventrolateral tongue. Incisional biopsy confirmed squamous cell carcinoma. Staging of the patient revealed that there was no nodal involvement or distant metastasis. The patient elected to have the tumor excised with CO2 laser under general anesthesia. Top right: the nodules are identified and marked with an ink before excision. Bottom left: intraoperative CO2 laser excision of the tumor. Bottom right: complete tumor excision and laser of the base to achieve hemostasis. Adapted with permission from: Jerjes W, Upile T, Hamdoon Z, Mosse CA, Akram S, Hopper C.
