Parapharyngeal space tumors (PSTs) have been studied in 14 cases treated in our clinic between 1960 and 1983. The results obtained are as follows: 1. The incidence of malignant PSTs predominated in males aged 40 years or over.2. Though subjective symptoms of PSTs are generally lacked, 80% of the malignant cases suffered from severe and persistent pain.3. The incidence of malignant PSTs in our clinic, 35.7%, was much higher than those described in other reports.4. The area from the paratopharyngeal to postpharyngeal wall was hyperemic and swollen only in the malignant cases.5. As indicative from the above 1-3, preoperative biopsy seems unnecessary, except when malignancy is strongly suspected etiologically and clinically.6. The combined CT-sialogram was very useful in revealing the size, extent and origin of tumors and in determining the best surgical approach for complete and safe excision.
