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.
For three patients of menorrhagia due to submucosal myomas with cavum lengths 13 to 15 cm, MEA was performed using the curved applicator.
Menorrhagia was improved in each case. No complications were encountered.
A large number of hysterectomies could be avoided using the new curved microwave applicator.
宫腔长度超过12厘米且宫腔形态异常的子宫增大是传统消融技术的禁忌症。使用直器械在伴有黏膜下肌瘤的大子宫中进行满意的子宫内膜消融很困难。为伴有增大且形态异常子宫腔的子宫微波子宫内膜消融（MEA）研制了一种新型直径4毫米的弯曲微波施源器。
对于3例因黏膜下肌瘤导致月经过多且宫腔长度为13至15厘米的患者，使用弯曲施源器进行MEA。
每例患者月经过多均得到改善。未出现并发症。
使用新型弯曲微波施源器可避免大量子宫切除术。
