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。
To investigate the relationship between bacteria and cyst infection in maxillofacial cyst fluid. Methods A total of 96 cases of oral, maxillofacial and neck cysts filled with cyst fluid were taken out and the cyst fluid was taken for bacterial culture immediately. The integrity and damage of the cyst wall, the positive rate of cyst and cyst were compared. . Results Of the 96 cysts, 37 were positive for bacterial culture, of which 2 were odontogenic cysts, 1 non-odontogenic cyst, and 14 were facial and cervical cysts. There was no significant difference in positive rate of bacterial culture between jaw cysts and facial and cervical cyst (P> 0.05), but the positive rate of bacterial culture more than 3cm cyst was significantly higher than that of cyst less than 3cm <0 .0 5). Conclusion There are a certain number of bacteria in the maxillofacial cyst fluid, some of which have certain relationship with cyst infection.
