Cervical tissue damage after Hegar dilator and continuous controllable balloon dilator dilation. (A) Percentage of patients with cervical epithelial damage. There was a statistically significant difference in the percentage of epithelial damage between the cervices dilated using the Hegar dilator (HeD) and the cervices dilated using the continuous controllable balloon dilator (CCBD). Mean ± standard error, n = 40 per group, P <0.001. (B) Percentage of patients with cervical basal membrane damage. There was a statistically significant difference in the percentage of basal membrane damage between the cervices dilated using the HeD and the cervices dilated using the CCBD. Mean ± standard error, n = 40 per group, P <0.001). (C) Percentage of patients with cervical stromal damage. There was a statistically significant difference in the percentage of stromal damage between the cervices dilated using the HeD and the cervices dilated using the CCBD. Mean ± standard error, n = 40 per group, P < 0.001).
