Is elective neck dissection necessary for the surgical management of T2N0 glottic carcinoma?

As occult metastasis was not detected in any of the neck dissection specimens in cT2N0M0 patients and no regional failure was experienced during the follow-up period, it was concluded that the neck could be followed up without performing elective neck dissection in the surgical management of cT2N0M0 glottic carcinoma patients.
