| khuki Total Posts: 18 | Posted: Sat Jun 16, 2007 02:59 pm Modifications to the radical neck dissection include the following: * Type I: The spinal accessory nerve is preserved. * Type II: The spinal accessory nerve and the internal jugular vein are preserved. * Type III: The spinal accessory nerve, the internal jugular vein, and the sternocleidomastoid muscle are preserved. Indications (usually an intraoperative assessment) for a modified radical neck dissection include the following: * Modified radical neck dissection type I - A clinically positive lymph node metastasis that does not include the spinal accessory nerve * Modified radical neck dissection type II - Metastatic tumor mass that involves the sternocleidomastoid muscle but not the internal jugular vein or spinal accessory nerve * Modified radical neck dissection type III - Indicated to remove clinically positive lymph node metastasis that does not infiltrate the nonlymphatic structures o Modified radical neck dissection type III is also indicated for patients with a palpable metastasis caused by a differentiated carcinoma of the thyroid. o According to some authors, modified radical neck dissection type III is indicated in patients with squamous cell carcinoma and an N0 neck when the original tumor is in the larynx, hypopharynx, or both. Other authors prefer further modification by sparing the submandibular triangle nodes because of low risk of metastasis to those nodes. |
