Abstract

Objective

This study aims to evaluate the clinical effectiveness of 3D SPECT/CT imaging in determining the osteotomy range during surgical treatment of Medication-Related Osteonecrosis of the Jaw (MRONJ) when combined with composite tissue flap techniques.

Methods

A retrospective analysis was conducted involving 12 patients diagnosed with MRONJ. Each patient underwent a 3D SPECT/CT examination prior to surgery, where the region of interest (ROI) was outlined in the 3D images. During surgery, the affected bone was excised 0.5 cm beyond the delineated ROI. Various types of composite tissue flaps were utilized to close the defects based on their size and location.

Results

Patients were followed for an average of 7.9 months (range: 6–12 months), with all 12 achieving successful outcomes devoid of complications such as pyorrhea.

Conclusion

The utilization of 3D SPECT/CT enhances the precision of determining the osteotomy range in MRONJ surgeries. Coupled with composite tissue flap techniques for defect closure, this approach yields favorable clinical outcomes.

三维SPECT/CT成像在确定药物相关性颌骨骨坏死手术治疗截骨范围中的临床效果：一项回顾性研究

目的：本研究旨在评价三维SPECT/CT成像结合复合组织瓣技术在药物相关性颌骨坏死（MRONJ）手术治疗中确定截骨范围的临床效果。方法：对12例诊断为MRONJ的患者进行回顾性分析。每位患者在手术前接受3D SPECT/CT检查，其中感兴趣区域（ROI）在3D图像中勾画。在手术中，受影响的骨在划定的ROI外0.5 cm处切除。根据缺损的大小和位置，采用不同类型的复合组织瓣来闭合缺损。结果：患者平均随访7.9个月（范围：6-12个月），所有12例患者均获得成功，无脓漏等并发症。结论：三维SPECT/CT的应用提高了MRONJ手术截骨范围的确定精度。结合复合组织瓣技术修复缺损，该方法可获得良好的临床效果。
