OBJECTIVES: To determine whether resection of level IIb is necessary in elective or therapeutic neck dissections.
STUDY DESIGN: Prospective case series.
METHODS: Level IIb nodes were analyzed for micrometastases as separate specimens in 160 neck dissections on 148 patients with squamous cell carcinoma of the head and neck.
RESULTS: In 106 elective neck dissections (N0 necks) from upper aerodigestive tract (UADT) and skin/parotid squamous carcinoma primaries, level IIb was involved in 4.5% and 33%, respectively. In 54 therapeutic neck dissections (N+ necks) from UADT and skin/parotid squamous carcinoma primaries, level IIb was involved in 25% and 71%, respectively. Apart from skin/parotid squamous carcinoma primaries, level IIb was never involved unless level IIa was also involved.
CONCLUSIONS: Level IIb nodes can be left in situ in UADT primary carcinomas in nontonsillar N0 necks without significantly compromising regional clearance of micrometastases.
