Classification of neck dissections: An evolving system

Recently, the Japan Neck Dissection Study Group presented a new system for classification of neck dissections based on a system of letters and symbols. The system permits a comprehensive “shorthand” method of precise designation of the neck dissection procedure, but has the disadvantage of departing radically from previously employed systems by utilizing an entirely new terminology and designation of lymph node groups. This factor portends a lack of acceptance by surgeons long accustomed to conventional terminology. The abbreviated and tabular method of classifying neck dissections, however, is advantageous, and would be useful if integrated into the currently used terminology.
