Demographic parameters in patients undergoing head and neck soft tissue tumor surgery in Imam Khomeini Hospital's Plastic Surgery Ward and Cancer Institute between 1372 - 1383

Soft tissue tumors are one of the most important reasons for cancer mortality. Determination of total frequency of cancers and their causes are difficult due to amplitude of soft tissue tumors and lack of prior evaluation. The aim of this study was to determine the frequency and distribution of maxillofacial soft tissue tumors. This study was a descriptive work or more appropriately، a case series. The population under study included patients with soft tissue tumors that referred to Imam Khomeini Hospital''s Plastic Surgery Ward and Cancer Institute between 1372 and 1383. SPSS 11. 0 (Statistical software) was applied for data analysis. Among 513 evaluated tumors، 475 (89%) were malignant and 56 (11%) were benign. There were 328 (64%) males and 185 (36%) females in our study. 293 (64%) males had malignant tumors، compared to 164 (36%) females. Approximately one fourth of patients were in the 6th decade of their lives. About sixty percent of patients were under age of 60. The most frequent tumor observed was less than 2. 5 cm in size. Squamous cell carcinoma was the most common tumor in our study with 200 (39%) cases and inferior lip was the most common site of soft tissue tumors. Since the mentioned frequency includes referral bias and the nature of our study did not allow the implementation of statistical tests، we suggest to perform a cross sectional study to look for probable correlations and patient survival.
