Objective: This study was designed to detect the application feasibility and accuracy of multiple planar re-construction (MPR) nerve display technology in desmoplastic fibroma therapy via argon-helium cryoablation. Meth-ods: 11 patients with systemic desmoplastic fibroma (8 males and 3 females) were recruited from XX hospital.Preoperative CT thin slice scan was performed on lesion area and MPR display technology was applied to detectthe association between tumors and nerves, whose results determined surgery plans. The conformal distributionof cryoprobes and ablation range were determined based on real-time nerve display images during surgery. Thecurative effects were assessed instantly, 3 months, 6 months and 12 months after surgery via MPR display imagesand clinical symptoms. Results: All surgeries were completed successfully guided by MPR nerve display images.Nerve display images explicitly demonstrated the correlation of nerves with tumors before surgery, rapidly mani-fested whether probe distributions were accurate and whether ablation ranges were satisfactory during surgery, andcompleted reexaminations to observe the recovery conditions of neural structure and functions through imagingand clinical symptoms in different periods after surgery. After operations, all patients underwent good recoveries inneural functions, expressing gradual remission of symptoms (like pains and limb sensory disorders). Conclusion: Inthe treatment of desmoplastic fibroma through cryoablation, adopting MPR display technology can guarantee the protection for neural structure while maximally ablating tumors, and greatly improve the accuracy of surgery, thus avoiding complications. Therefore, this technology should be further applied in clinic.
