Abstract

Background.

To determine the presentation and management of parotid lesions requiring excision in a largely Chinese Asian population.

Methods.

Retrospective study of 118 consecutive parotidectomies.

Results.

Thirty-seven percent were Warthin's tumor (WT), 33% pleomorphic adenoma (PA), 21% other benign disease (OBD), and 9% malignant tumor (MT). Mean age was significantly different between benign (51 years) and malignant (40 years) lesions. MT decreased above 50 years, but increased five times with pain and two times with a noninferior pole lesion. Sensitivity of fine-needle aspiration (FNA) for differentiating benign from MT = 78%, for WT =5 8%, for PA =82%, for OBD = 28%, and for MT = 38%. CT scans did not alter WT management. Facial nerve (FN) paresis was not associated with histology, tumor size, site, or parotidectomy type.

Conclusions.

This is the first report documenting that most benign parotid tumors are WT and not PA. MT risk is greater in those less than 50 with pain and a noninferior pole lesion. Cystic lesions such as WT require great care in the evaluation of FNA findings. © 2003 Wiley Periodicals, Inc. Head Neck 25: 543–548, 2003
