Materials and Methods
The institutional review board of the Stomatological Hospital of Peking University (Beijing, China) approved this study. Owing to the retrospective nature of this study, it was granted an exemption in writing by the institutional review board. From September 1995 through July 2010, inpatients who underwent a neck dissection at the Department of Oral and Maxillofacial Surgery, Stomatological Hospital, Peking University for pathologically diagnosed SCC were screened for this study. Patients'
Patient Characteristics
In total, 637 eligible patients were enrolled at random in this study (355 men and 282 women; mean age, 58.6 yr; age range, 19 to 87 yr). The demographic data of the 637 patients are presented in Table 1. The cutoff date for obtaining follow-up data for the surviving patients was July 31, 2013. The median follow-up for these patients was 68 months (interquartile range, 48 to 95 months).
All 637 patients who underwent unilateral neck dissections were divided into 3 groups (MRND/RND group, 248
Discussion
Currently, the neck is staged by palpation and different imaging techniques, including ultrasound, computed tomography, magnetic resonance imaging, and more recently positron-emission tomography and computed tomography, which are more accurate than palpation alone.14, 15 However, approximately one third of nodal metastases are smaller than the 3-mm detection sensitivity limit of the currently available imaging techniques.16 Many studies have shown that elective neck dissection results in better

Feng et al. [3] in a larger retrospective study noted that a SND (I–III) is not associated with significant difference in recurrence and overall survival rates between cN0 and cN+ patients. The main morbidity attributed to the nodal dissection occurs while dissecting tissue around SAN i.e., level IIB and V.
