摘要: 目的:探讨不同类型下颌骨骨折对上气道间隙的影响。方法:选取不同类型下颌骨骨折患者56例(男29例,女27例),正常对照组20例(男12例,女8例)。将整个上气道分为腭咽段、舌咽段、喉咽段3个区,所有人在同一条件下进行上气道锥形束CT(CBCT)扫描,数据经DICOM格式直接转入Simplant软件中,测量上气道各段容积及气道总容积。结果:单、双侧下颌角线性骨折患者喉咽气道容积及气道总容积明显变小(P<0.05)。双侧下颌骨体部线性骨折及颏/颏旁粉碎性骨折对舌咽气道、喉咽气道容积及气道总容积影响显著,严重者易引发通气障碍。结论:三维重建测量技术,可直观显示双侧下颌骨体部线性骨折和颏/颏旁粉碎性骨折后,上气道间隙的减小,指导临床。

Abstract: Objective: To assess the changes of upper airway clearance after different type of mandibular fractures.  Method: 56 patients with different type of mandibular fracture and 20 normal controls were chosen. The whole upper airway was divided into three parts,palatopharyngeal section,glossopharyngeum section, and laryngopharynx section. The upper airway of all patients were scanned by CBCT under the same condition. The scanning data were directly inputted to Simplant software in DICOM format, the total volume and each section of upper airway were measured. Results: In patients with unilateral or bilateral mandibular angle fractures, the volume of laryngopharynx airway and whole upper airway obviously decreased (P<0.05). In patients with bilateral mandibular body and chin / para-chin comminuted fractures, the volume of glossopharyngeum, laryngopharynx airway and total upper airway significantly decreased (P<0.05). Conclusion: Bilateral mandibular body and chin / chin comminuted fracture leads to breathing volume decrease of upper airway.

Key words: CBCT, Simplant software, mandibular fracture, the upper airway clearance
