title: Radical versus supraomohyoid neck dissection in the treatment of squamous cell carcinoma of the inferior level of the mouth.
abstract: The therapeutic paradigm for neck metastasis of squamous cell carcinoma (SCC) in the lower level of the mouth has changed due to survival.
  
  
  OBJECTIVE
  A comparative study between radical (RND) versus selective neck dissection (SND).
  
  
  METHODS
  An analysis of mouth SCC in the lower level of the mouth in 460 files from the Head & Neck and ORL Department of the Heliopolis Hospital, from 1978 to 2002. In the RND the metastathic rate in levels IV and V was assessed; in the SND the presence and site of recurrence was identified. The chi square test with the Yates correction was the chosen statistical method.
  
  
  RESULTS
  In the RND the metastatic rates were 5.8% (level IV) and 4.6% (level V) for cNO cases, and 9.9% (level IV) and 5.9% (level V) for cN+ cases; for level I only the rates were 11.0% for cNO cases and 5.5% for cN+ cases. In the SND the number of recurrences was 4 (4.1%) in 97 neck dissections (pNO) and 2 (10%) in 20 neck dissections (pN+). There was no advantage in using radiation compared to non-irradiated cases (5.6% and 5.7%).
  
  
  CONCLUSIONS
  The SND may be used for SCC of the lower level of the mouth.
