When a straight--or even partially curved--dilator cannot traverse the tortuous path of a distorted canal, the small flexible hysteroscope may offer a solution, allowing identification of the anatomic obstruction and visualization of the course of the cervical canal. Prior visualization of the canal enhances proprioception with the dilating instrument and improves the likelihood of safe uterine access.
