Objective. To report on the efficacy of Iso-C 3-dimensional intraoperative spinal navigation in excising osteoid osteomas.

目的:研究切除脊柱骨样骨瘤术中C臂三维导航的作用.

summary of background data. curative treatment of osteoid osteomas entails complete intralesional excision of the nidus.

背景信息摘要：骨样骨瘤的根治方法是病变内完全切除病灶。

single cancellous osteomas, unlike exostosis , are a relatively rare lesion in the external auditory canal.

单一性疏松骨瘤，不像外生骨疣，是一个外耳道较少见的病灶。

in this particular case , there were osteomas of the skull , a periampullary adenocarcinoma , and epidermal inclusion cysts

在这个特殊的病例中，有颅骨骨瘤，壶腹周围的腺癌和表皮囊肿。

Further processing of resulting boundary with binary morphological operation produces a closed osteomas contour. So osteomas is isolated from background.

最后利用二值形态运算进一步处理，便可得到封闭的骨肿瘤边界，从而将骨肿瘤与背景分离。

to date, only less than 50 osteomas of the tongue have been reported in the literature.

目前文献上舌部骨瘤之报告未超过50例。

method. iso-c 3-dimensional intraoperative navigation was used to localize osteoid osteomas of the spine in 4 patients.

方法：术中ISO-C3D导航技术用于4名患者术中脊柱骨样骨瘤的定位。
