OBJECTIVE: The clinical features and patterns of growth, relative to age, were examined in @entity1 with @entity7854 to investigate disease progression and site of origin. @entity1 AND METHODS: We retrospectively reviewed 72 @entity1 younger than 15 years with intraoperatively confirmed @entity7854 diagnosed using the inclusion criteria of Levenson et al. @entity1 demographics, history, and otoscopic and operative findings were evaluated. Correlation between mass volumetric and operation age was analyzed in @entity1 with closed-type masses. Parameters of disease extent of middle ear quadrant, @entity2170 , @entity14361 , invasion of the @entity2267 , and type of mass were assessed relative to age at operation. RESULTS: Mean @entity1 age was 63.1 months (range, 20-179 months), with 51 @entity1 (70.8%) being asymptomatic and diagnosed incidentally. Nineteen @entity1 (26.4%) had closed-type cystic masses, and 53 (73.6%) had @entity75 . The volume of closed-type masses was linearly correlated with age at operation. Logistic regression showed that increased age at operation was associated with a lower proportion of anterosuperior quadrant lesions, resulting in uncertainty about the site of origin. The possibility of open-type masses also increased according to age at operation. CONCLUSION: @entity7854 shows growth and extension over time. Early detection and intervention are necessary to avoid advanced disease.
