Introduction: External and middle ear diseases and tumors are among the most common cases referred to the ear clinic. These lesions can range from benign inflammatory lesions to metastatic tumors. Therefore, in this study, we aimed to study middle and external ear biopsy lesions to obtain information about the frequency distribution of gender, age and their clinical symptoms so that we may be able to take steps to detect them early and prevent their spread.Methods: This descriptive and cross-sectional study was performed retrospectively. The data were collected through a premade questionnaire, including demographic data such as age, gender, the precise anatomical location, the involved side, clinical symptoms, and pathology report. Then, the obtained data were statistically analyzed through SPSS software version 17.Results: Total 542 patients were enrolled in this study, whom 332(61.3%) of them were male and 208 (38.3%) of them were female. The mean age of patients was 36.93 18.51 years old. Between them 57 (10.5%) of cases were malignant, and 485 (89.5%) were benign. There was a significant relationship between the pathologic types of middle and external ear lesions with age, gender, and clinical symptoms (PV < 0.001). Most lesions were seen in men older than 50 years. The benign lesions such as cholesteatoma were the most widespread lesion in the middle ear, mostly observed on the left side. The majority of patients with cholesteatoma were between 20 and 39 years old.Conclusion: The results of this study showed that there is a close relationship between clinical symptoms and the type of the lesion. Most benign lesions presented with otorrhea and hearing loss, while most malignant lesions were presented as ulcerated lesions.Keywords: External Ear; Middle Ear; Pathology; Lesion
