OBJECTIVE: To determine patterns of regional @entity3 in @entity1 with advanced stage @entity957 of the auricle. STUDY DESIGN: Case series with chart review. SETTING: University-based tertiary care hospitals. SUBJECTS AND METHODS: We analyzed 41 @entity1 with stage III and @entity957 of the auricle. RESULTS: The mean age was 74.2 years (range, 20.6-91.7 years). Thirty-five @entity1 (85.4%) were stage IV. Twenty-nine @entity1 (70.7%) had a prior history of nonauricular, nonmelanotic @entity1489 . Twenty-four @entity1 (58.5%) had regional @entity3 to either the cervical or parotid nodal basin. In @entity1 with cervical @entity3 , the involvement by level was 6.7% (n = 1), 80.0% (n = 12), 46.6% (n = 7), 13.3% (n = 2), and 40.0% (n = 6), respectively. Of the 6 @entity1 with a level 5 @entity3 , 3 had primaries in the preauricular region, 2 had primaries of the auricle, and 1 had a primary of the postauricular region. @entity66 was present in 2 @entity1 (9.1%) with cervical @entity3 and in 4 @entity1 (18.2%) with periparotid lymph node @entity3 . Perineural invasion was seen in 84.4% of the study population. The recurrence rate was 46.3% (n = 19). The median time to recurrence was 28.3 months. CONCLUSION: @entity1 with advanced stage auricular @entity957 have a high rate of regional @entity3 and recurrence. When planning neck dissections for these @entity1 , level 5 should be included in the resection. @entity1 demonstrating @entity1442 without clinical or radiographic evidence of @entity3 to the parotid or cervical drainage basin should undergo a parotidectomy and comprehensive neck dissection.
