Pleomorphic adenoma of the pterygopalatine fossa: a case report

Pleomorphic adenoma (PA) is the most common benign tumor of the major salivary glands. It can also Occur in the minor salivary glands, mainly in the oral cavity, and in other sites in the head and neck region. We present a very rare case of PA in the pterygopalatine fossa. Surgical resection of the tumor was performed via the transmaxillary approach. The patient has experienced neither surgical complications nor recurrence in the past 3 years. This case suggests that a localized benign tumor in the pterygopalatine fossa can be removed safely and efficaciously via a transmaxillary approach.
