title: The role of selective neck dissection in pathological N1 squamous cell carcinomas of the head and neck.
abstract: OBJECTIVE
  This study aims to evaluate the effectiveness of selective neck dissection (SND) in stage pN1 head and neck cancers.
  
  
  METHODS
  Patients who underwent neck dissection due to squamous cell carcinoma of oral cavity, larynx, oro-hypopharynx were evaluated retrospectively. Sixty-one patients diagnosed with pathological N1 by neck dissection were included in the study. Thirty-four of the 61 necks, to which SND was applied, comprised the study group, and 27 necks, which underwent comprehensive neck dissection (CND), comprised the control group.
  
  
  RESULTS
  Neck recurrence rates were 4.9% for all cases, 5.9% for the SND group and 3.7% for the CND group. Two- and five-year disease-specific survival rates were similar for SND group (78.6%, 72.5%) and CND group (90.5%, 82.9%). Two- and five-year overall survival rates were also similar for SND group (67.6%, 58%) and CND group (81.5%, 66%). None of them were significantly different between groups (p>0.05).
  
  
  CONCLUSIONS
  Selective neck dissection provides comparable results to CND in the treatment of pN1 necks.
