Fine-needle aspiration cytology in tumors and tumor-like conditions of the oral and maxillofacial region

Abstract

Four major causes of error were identified: material adequacy criteria, sampling technique, cytologic interpretation, and limitations of the procedure. FNAC proved to be a safe, accurate, inexpensive, and patient-friendly in the effort to establish preoperative diagnosis in tumors and tumor-like conditions of the oral and maxillofacial region. The authors have proposed modification in the mathematic computation of diagnostic accuracy, adding the parameter of nonconcordance with histologic typing of FNAC.
