Objective To explore the feasibility and value of three-dimensional image body surface projection technique in preoperative localization of intracranial lesions.
Methods Fifteen patients with operation assisted by three-dimensional image surface projection positioning technology were selected, including 9 cases with puncture and drainage of intracranial hematoma, 2 cases with resection of meningioma, 2 cases with resection of cerebral arteriovenous malformations and 2 cases with microvascular decompression. The positioning effect was analyzed and the positioning experience was summarized.
Results Puncture and drainage of intracranial hematoma were successful by one time in 9 cases, and meningioma of three cases and vascular malformations of three cases were located in the designed bone window; 3 cases had paravenous sinus lesions, the location of venous sinus could be accurately described before operation.
Conclusion The three-dimensional image body surface projection positioning technology can accurately locate brain lesions, and adding body surface markers can increase the positioning accuracy of this technology.
