Abstract

Objective
To evaluate the incidence of metastases to the Level IIb (supraspinal) in patients submitted to neck dissections for squamous cell carcinoma (SCC) of the upper aerodigestive tract and to identify the regional predictive factors for nodal metastases at this level.
Methods
All neck dissections (ND) carried through by the Head and Neck Surgery Department (INCAMS-RJ) in the period of four months had been studied retrospectively. A hundred and fifty- seven dissections performed in 97 patients had been analyzed. All the dissections had the separate levels in the surgery by the surgeon or by the first assistant and the Level IIb was dissected separately from the remaining levels.
