title: Supraomohyoid neck dissection.
abstract: BACKGROUND
  Supraomohyoid neck dissection (SOHND) has assumed increasing importance as a staging lymphadenectomy in patients with N(o) oral and oropharyngeal squamous cell carcinoma (SCC), as well as a potentially curative procedure in selected patients with limited metastatic disease in the neck.
  
  
  METHODS
  Retrospective chart review of 287 patients who had a total of 320 SOHND for SCC between 1986 and 1993 as a follow-up to an earlier report that covered our experience between 1980 and 1985. After excluding 24 patients who also had local recurrence, or a new primary, the remaining 296 SOHND were assessed for the effectiveness of tumor control in the neck.
  
  
  RESULTS
  Of 248 elective SOHND, clinically negative nodes proved histologically positive in 60 patients (25%), only 4 of whom failed in the neck (7%). A total of 48 patients (16%) had a therapeutic SOHND for limited N+ disease, confirmed pathologically in 31, with neck recurrence documented in 2 (6%). Nodes proved negative histologically in 205 patients, 10 of whom failed in the neck (5%). Nine of the 16 patients with neck recurrence had received postoperative radiation therapy and 9 recurred within the field of the SOHND.
  
  
  CONCLUSIONS
  SOHND is a reliable staging procedure in patients with N(o) oral or oropharyngeal SCC. Therapeutic SOHND, in conjunction with postoperative radiation therapy, was highly effective in controlling neck metastases in carefully selected patients with limited disease in the upper neck.
