[Clinical pathology and anatomy features of parapharyngeal region neoplasms: a report of 69 cases].

Objective: To analyze the relationship between clinical pathology and anatomy features of primary neoplasms in the parapharyngeal regions.

Method: A total of 69 cases of primary neoplasms in the parapharyngeal regions were included. Fifty-eight cases were benign, and 11 cases were malignancy.

Result: Disorders of swallowing, breath or speaking were the common symptoms of neoplasms located in parapharyngeal regions. The majority of neoplasms located in parapharyngeal regions were benign. CT and MRI provides useful information about tumor size, shape and extent. The relationship of the tumor and vessel could be shown with selective angiography.

Conclusion: Primary parapharyngeal regions neoplasms are rare in head and neck tumors. Surgery is the main treatment for parapharyngeal regions tumors. The operation type was decided by the location and the pathological type of the neoplasm.
