144例颌面部间隙感染患者的流行病学分析

目的：探讨口腔颌面部间隙感染患者的流行病学特点。方法：回顾分析144例口腔颌面部间隙感染患者的病历资料。结果：144例口腔颌面间隙感染患者男女比为1．18∶1；60岁以上人群（34．02％）为好发人群；牙源性感染为首要致病原因（65．97％）；单间隙感染70例（48．61％），多间隙感染74例（51．39％），下颌下间隙在单间隙感染患者和多间隙感染患者受累间隙所占比率分别为31．43％和30．81％。合并危及生命的并发症以气道梗阻最为常见（16．67％）。结论：口腔颌面部间隙感染患者以牙源性引起的间隙感染最为常见，应及早有针对性（特别是危及生命的并发症）进行相应处理。

An epidemiological analysis of 144 cases with maxillofacial space infection

Objective:To analyze the epidemiological characteristics of patients with maxillofacial space infection(MSI).Meth-ods:A retrospective review of 144 patients with MSI was carried out and the medical records were analyzed.Results:The ratio be-tween male and female cases was 1.18∶1.34.02% of the patients were aged above 60 years.The most common cause was odonto-genic infection (65.97%).The submandibular space was the most commonly involved in both single space and multiple space infec-tion(31.43% and 30.81% respectively).The most common life-threatening complication was upper airway obstruction(23.8%). Conclusion:The most common cause of maxillofacial space infection was odontogenic infection.Treatment should be timely and di-rected agaist the cause.Special attention should be paid to control the life-threatening complications.
