Abstract Introduction: Head and neck tumors are a collection of tumors with different histopathology that originate from upper aero-digestive tract, skin, salivary glands, thyroid and parathyroid glands. It has been proven that various risk factors such as tobacco, alcohol and some viruses (HPV6 & HPV11) increase the prevalence and incidence of such tumors and that’s why the frequency and prevalence of head and neck tumors vary in different areas, throughout the world. Objective: study was determining the relative frequency of these kinds of tumors and the respective risk factors. Materials and Methods: In a cross-sectional retrospective and descriptive study, data of patients with histologically confirmed diagnosis of head and neck tumors, were extracted from their recorded files in Amir-Al-Momenin hospital and entered into SPSS V.16 software and using frequency tables and graphs the data were analyzed. Results: In total, 558 patients with mean age of 54.34±16.37 years including 372 males (66.7%) and 186females (33.3%) were admitted with diagnosis of head and neck tumors, from 2001 to 2012 in this hospital. (74/7%) of the tumors were malignant. The most frequent tumor was Squamous Cell Carcinoma with 279(50%) cases. The most frequent site of tumors was larynx with 195 (34/9%) cases. Having reviewed social habits of the patients we found that (51/4%) were smoker (21/5%) opium addict ( 9.7%) alcoholic and (8.6%) of them used hubble bubble. As revealed, (1.6%) of patients had positive family history and (1.6%) of them had history of another tumor in the past medical history .The most frequent chief complaint of all the patients referred to this center with head and neck tumor was hoarseness. Conclusion: Data of our samples were similar to those in some studies but different in some cases. Reason of such variations may be definition of samples and other biases in different studies, but the life style and different risk factors also may be responsible for these differences. So further comparative studies in other geographical regions are recommended.
