Background: The use of selective neck dissection (SND) in the treatment of clinically node-positive necks remains controversial.
Methods: A total of 48 patients with laryngeal and hypopharyngeal carcinoma underwent 53 primary, therapeutic SNDs (levels II-V) and were retrospectively evaluated.
Results: Regional metastases were staged as pN1 in 8 patients, pN2a in 3, pN2b in 29, and pN2c in 8. Of the primarily treated necks 45 of 53 (85%) were irradiated postoperatively. Extracapsular spread was found in 27 neck specimens (51%). Regional recurrences in level I occurred in one patient (1.8%) and in level II-V in 5 patients (9.4%). The actuarial overall survival at 4 years was 36.5%.
Conclusions: In selected cases therapeutic SND (levels II-V) in node positive (N1,2) patients with laryngeal or hypopharyngeal carcinoma does not lead to increased risk for recurrence in level I or other levels of the neck and is therefore a safe procedure.
