A Case Report of Pleomorphic Adenoma in Maxillary Sinus / 대한이비인후과학회지

Pleomorphic adenoma is the most common benign tumor of the salivary gland. It occurs mainly in the major salivary gland, but it can be originated from any minor salivary glands and upper airway. Pleomorphic adenoma arising in the maxillary sinus is extremely rare. Recently, we have experienced a huge pleomorphic adenoma originated in the maxillary sinus. The patient was 64 years old woman and the tumor in the left maxillary sinus extended to the infratemporal fossa, pterygopalatine fossa, and parapharyngeal space through destructed maxillary sinus bony wall. Surgical resection was performed via midfacial degloving approach and the result of surgery was successful. We report this case with the review of literature.
