Hysterectomy is an effective treatment for refractory menorrhagia resistant to conservative methods and the commonest major gynecologic operation. However, hysterectomy is associated with substantial post-operative morbidity. As an alternative to hysterectomy, it has become possible to destroy the endometrium in situ with minimal access techniques. Unfortunately, hysteroscopic ablation techniques require considerable surgical skill and long learning curve. Second generation ablative devices have been developed for an effective, safe, quick and easy treatment of mennorrhagia. Microwave endometrial ablation (MEA) at a frequency of 9.2 GHz was first described in 1995 and its effectiveness has been confirmed in randomized trials. Recently a new curved microwave applicator was developed for MEA at 2.45 GHz for uteri with an enlarged distorted uterine cavity. Using the applicator, menorrhagia caused by submucosal myoma nodes was successfully treated. A large number of hysterectomies could be avoided by MEA.
