Answer

Microwave endometrial ablation (MEA) was developed and has been used in Europe since 1996. It uses high-frequency microwave energy to cause rapid but shallow heating of the endometrium. Microwaves are selected so that they do not destroy beyond 6 mm in depth.

MEA requires 3 minutes of time and only local anesthetic. It is proving to be as effective as TCRE.

In a Japanese study, investigators found that multiple MEAs in the same region in women with adenomyosis and menorrhagia was more effective than conventional single ablation treatment, as well as resulted in higher patient satisfaction rates. [41]
