颌面颈部囊肿囊液细菌与感染的关系

探讨颌面颈囊肿囊液中的细菌与囊肿感染的关系。方法　对 96例口腔颌面颈部各类囊液充盈的囊肿手术时抽出囊液立即作细菌培养 ,进行囊壁完整与破损、颌骨囊肿与面颈囊肿、囊肿大小的细菌培养阳性率的比较。结果　 96例囊肿中 ,细菌培养阳性者 37例 ,其中牙源性囊肿 2 2例 ,非牙源性囊肿 1例 ,面颈囊肿 14例。囊肿完整者与破损者 ,颌骨囊肿与面颈囊肿细菌培养阳性率均无显著性差异 (P>0 .0 5 ) ,但大于 3cm囊肿的细菌培养阳性率明显多于小于 3cm的囊肿 (P<0 .0 5 )。结论　颌面囊肿囊液中有一定数量的细菌存在 ,其中部分细菌对囊肿的感染与增大有一定的关系。

The relationship between bacteria of liquid and infection in patients with oral maxillo-facial-cervical cysts

Objective To determine the relationship of bacteria of liquid and infection in patients with oral maxillofacial cervical cysts. Methods The liquid was sucked immediately just before operation in 96 cases which cystic wall was not damaged or fistula and the liquid was plentiful and the specimen were made cultrue of bacteria. Then statistical analysis of the result was done between the group of jaw cyst and facial cervical cyst, the group of complete wall and damaged cystic wall, the group of big cyst and small cyst. Results In 96 cases, 37 were positive culture of bacteria, which 22 cases from odontogenic cysts; 1 from non odontogenic cyst and 14 from facial cervical cysts. There were no obvious difference between the group of jaw cyst and facial cervical cyst, the group of complete cystic wall and damaged cystical wall( P >0.05), but the group of big cyst and small cyst( P <0.05). Conclusion Some bacteria exist in the cystic liquid of oral maxillofacial cervical cysts, and some of them may lead to infect the cysts.
