It is now possible to limit the extent of selective neck dissection for mucosal squamous cell carcinoma of the head and neck by sparing selected lymphatic levels thereby reducing the morbidity. This has been brought about by our improved understanding of the metastasis behavior of these cancers. Studies have demonstrated similar rates of neck recurrences and survival after selective neck dissection compared to modified radical neck dissection. ⋯ SND (I-III) is a sound and effective procedure in the management of clinically negative neck in squamous cell carcinoma of the oral cavity. Clinically N0 neck but pathologically N+ neck requires adjuvant radiation therapy. It probably has a therapeutic role in the selected cases of squamous cell carcinoma of the oral cavity with N1 neck, and in these cases an extension of dissection to levels IV and V is beneficial.
