OBJECTIVE To determine the distribution of ovarian dermoid cysts in a large series of women. METHODS Observational study (Canadian Task Force classification II-3). METHODS University teaching hospitals. METHODS Three hundred thirty-six women. METHODS Evaluation of operative reports. RESULTS Dermoid cysts had a mean diameter of 5.6 cm. They were present in the right ovary (48.8 %), left ovary (37.8%), and bilaterally (13.4%). Unilateral cysts were more frequent in the right ovary (56.4%) than in the left (p = 0.002, odds ratio 1.7, confidence interval 1.2-2.3). This was significantly different from the expected 50% (4.45, chi2). A similar predisposition was found when we included women with bilateral cysts (p < 0.01, OR 1.5, CI 1.1-1.9). Patient age and size of cyst did not differ between those with left and right lesions. CONCLUSIONS In this large cohort of women, ovarian dermoid cysts had a predisposition to a right lateral location.
