Background: Maxillofacial cysts and tumors are major causes of jawbone destruction; and may occasionally result in early mortality of patients. This study purposed to radiologically and clinically evaluate maxillofacial cysts and tumors among Iranian patients. Methods: A retrospective study was conducted on medical records of patients referred to surgical departments of two hospitals (Bisotun and Imam Khomeini) in Kermanshah, Iran, from 2008 to 2012. Totally, 347 records were reviewed and 85 cases with intraosseously maxillofacial lesions were selected. The information including age, gender, type of lesion and its characteristics (number of lesions, anatomic location, radiolucency, and lesion border) were collected. Data were presented by descriptive statistics using SPSS 20 software. Results: Overall occurrence of maxillofacial lesions was 24.5% (85/347) including 41 cysts, 14 benign tumors, 10 malignant tumors, and 20 bone diseases in jaws. The most common cysts, benign tumor, malignant tumor, and jawbone disease was radicular cyst (41.5%), ameloblastoma (57.1%), squamous cell carcinoma (75%), and central giant cell granuloma (65%), respectively. The posterior region of mandible and anterior part of maxilla were respectively identified as the first and second most common anatomic locations for development of the maxillofacial lesions. The peak age of patients was third and fourth decade for the majority of lesions but seventh and eighth decade for squamous cell carcinoma. Conclusions: Our findings are generally consistent with those reported in the literature. However, there are a few dissimilarities that may be due to racial and/or environmental differences.
