ABSTRACT

Background and Objectives: Lymph node metastases has a high prognostic value in patients with parotid gland carcinoma. However, a consensus regarding the indication of elective neck dissection (END) has not been reached. Most authors have advocated performing a neck dissection based on the histology of the primary parotid carcinoma and the tumor grade. Materials and Methods: A retrospective analysis was undertaken targeting 16 patients who were previously treated for primary carcinoma of the parotid gland with a clinically negative neck at Department of Otorhinolaryngology?Head and Neck Surgery. Eleven patients with high grade parotid carcinoma except two cases of the adenoid cystic carcinoma and three cases of low grade parotid carcinoma were evaluated to identify occult neck metastases. Results: Lymph node metastasis was detected in one (9.1 %) of the 11 patients with high grade parotid carcinoma who underwent elective neck dissection. One case of positive lymph node was squamous cell carcinoma as primary parotid cancer (33.3 %). Conclusions: Elective neck dissection seems to be necessary for the treatment of high grade parotid cancer with squamous cell carcinoma. However, there may be controversy over the cases of high grade parotid cancer except for the squamous cell carcinoma. (J Clinical Otolaryngol 2014;25:44-48)
