* All patients with a primary tumor stage of T3 and more with no previous radiotherapy (for other malignancies than laryngeal carcinoma) history underwent elective neck dissection according to the localization and lateralization of the tumor. No neck dissection was performed for patients whose preoperative diagnosis was verrucous carcinoma. For patients with a T1 and T2 tumor stage, elective neck dissection was performed only if clinical and radiological metastasis presence or occurrence was present.

Ŧ: Follow-up period for papillary carcinoma is less than 5 years, 5-year survival rates are not available.
