selective neck dissection
Also written as: SND — selective neck dissection
Surgical removal of specific lymph node groups in the neck while preserving non-lymphatic structures.
Full Definition
A targeted surgical approach that removes predetermined lymph node levels based on the primary tumor's predictable drainage patterns, while preserving the spinal accessory nerve, internal jugular vein, and sternocleidomastoid muscle. This procedure is indicated for clinical N0 necks with high risk of occult metastases or for limited nodal disease. The specific levels dissected vary by primary tumor site, with common variations including levels II-IV for oral cavity cancers and levels II-V for oropharyngeal cancers.
Usage
Usage note: Specify lymph node levels removed in documentation.
