Role of open incisional biopsy in parotid tumors.
OBJECTIVE
Parotid gland enlargement due to diffuse pathologic processes represents a diagnostic challenge for the surgeon. In such cases, fine-needle aspiration is inconclusive and superficial parotidectomy is usually performed.


METHODS
The authors treated eight patients who underwent open incisional biopsy of the parotid gland with continuous monitoring of the facial nerve.


RESULTS
In all cases, fine-needle aspiration cytology did not provide a definitive diagnosis while open incisional biopsy provided an accurate diagnosis of a lymphoproliferative disorder, with no operative complications.


CONCLUSIONS
In certain infiltrative parotid diseases such as lymphoepithelial or lymphoproliferative diseases, when fine-needle aspiration biopsy is insufficient as tissue architecture is an important component of the pathological diagnosis, an open incisional biopsy can be considered. This procedure can provide an accurate histological diagnosis while avoiding superficial parotidectomy.
