Abstract
INTRODUCTION: An enlarged uterus of more than 12 cm in cavum length with a distorted cavity is a contra-indication for conventional ablative techniques. It is difficult to perform satisfactory endometrial ablation in a large uterus with submucosal myomas using straight instruments. A new curved microwave applicator 4 mm in diameter was developed for microwave endometrial ablation (MEA) for uteri with an enlarged distorted uterine cavity. METHOD: For three patients of menorrhagia due to submucosal myomas with cavum lengths 13 to 15 cm, MEA was performed using the curved applicator. RESULTS: Menorrhagia was improved in each case. No complications were encountered. CONCLUSION: A large number of hysterectomies could be avoided using the new curved microwave applicator.
