Abstract
Controversy remains regarding extending the level I-III selective neck dissection (SND) to include level IV in the management of the clinically N0 (cN0) neck in patients with oral squamous cell carcinoma (OSCC). Histologic and follow-up data of 87 patients with previously untreated OSCC undergoing I-IV SND and 41 undergoing I-III SND between 2002 and 2006 were reviewed. Of the 98 I-IV SNDs performed, 4 had involvement of level IV. No relationship between tumor variables and level IV involvement was identified. Survival analysis failed to demonstrate a significant difference between I-III and I-IV SND in terms of developing neck recurrence in the 2 years following surgery. Level I-III SND is effective management of the cN0 neck (when coupled with postoperative radiotherapy in selected cases) in patients with OSCC, although it is recommended that a larger prospective study be performed in this field.
