title: Lymphatic metastasis to the supraretrospinal recess in laryngeal squamous cell carcinoma.
abstract: In order to evaluate lymphatic metastasis to the supraretrospinal recess (SRSR) in laryngeal squamous cell carcinoma (SCC), we separately dissected SRSR lymph nodes and submitted them to pathological examination. Fifty-three lateral neck dissections (LNDs), 2 radical neck dissections (RNDs), and 19 modified RNDs were performed in 49 previously untreated patients with laryngeal SCC. The nodal status of the patients was N0 in 29 patients, N1 in 17, and N2 in 3. The neck was pathologically positive in both RNDs (100%), in 7 of 19 modified RNDs (37%), and in 7 of 53 LNDs (13%). No SRSR lymph nodes were positive in any of the dissection materials. No metastasis was found in the SRSR lymph nodes in the N0 necks treated with LND, and none was found even in N1 and N2 necks treated with RND or modified RND. We conclude that the SRSR may be left undissected during treatment of an N0 neck with LND so that accessory nerve dysfunction can be minimized and operative time can be saved.
