已知下颌矢状截骨术和下颌第三磨牙拔除术有损伤下齿槽神经的危险。但受损伤后感觉完全恢复需要多长时期,从临床上预测神经再生采用哪些描写术语更合适,以及继发于第三磨牙拔除同升支矢状截骨术感觉改变的预后有无差异。本研究回答上述问题。材料和方法作升支矢状截骨术(基本采用改良Epker术式)。术中给地塞米松8mg,逐渐减量至术后第二天。第三磨牙拔除后当病人诉述神经功能改变时,同样给予上述处理。研究采用两种表格进行调查。第一种是日记式的,即从术后立即开始到术后6个月每隔
It is known that mandibular sagittal osteotomy and mandibular third molar extraction have a risk of damaging the alveolar nerve. However, how long it will take to recover completely after injury? It is more appropriate to predict which terms are used in clinical practice and whether there is any difference in the prognosis of secondary sagittal osteotomy after secondary molar removal. This study answers the above questions. Materials and methods for ascending sagittal osteotomy (the basic use of modified Epker technique). Intraoperative dexamethasone 8mg, tapering to the second day after surgery. After the removal of the third molar when the patient complained about changes in nerve function, the same treatment given to the above. The study used two forms of investigation. The first is diary, that is, immediately after the start to 6 months after surgery every other
