作者统计五年间就诊病人22,036人,其中可能形成上齿龈瘘者185例,但实际形成瘘孔者28例。病因讨论:1.乳幼儿上颌窦炎10例,5例齿源性,其中3例形成上齿龈瘘,2例鼻源性,3例原因不明。因此,齿源性乳幼儿上颌窦炎容易发生龈瘘。2.齿源性上颌窦炎21例,6例形成上齿龈瘘,其中拔牙创口感染形成瘘管者4例;由龋齿引起的2例。3.术后面颊部囊肿28例,其中6例形成上齿龈瘘,均为上颌窦根治术后发生。因此,在诊断时应详问既往史和X线检查,必要时手术探查及病理检查。
The authors calculated 22,036 patients over the five-year period, of which 185 may be upper gingival fistulas, but 28 were actually formed by fistula holes. Etiology: 1. Infantile maxillary sinusitis in 10 cases, 5 cases of odontogenic, of which 3 cases of upper gingival fistula, nasal 2 cases, 3 cases of unknown cause. Therefore, dental origin of children prone to maxillary sinus inflammation gingival fistula. Tooth-derived maxillary sinusitis in 21 cases, 6 cases of upper gingival fistula, of which tooth extraction wound infection in 4 cases of fistula; caused by dental caries in 2 cases. Postoperative 28 cases of cheek cyst, of which 6 cases of upper gingival fistula, are maxillary sinus radical surgery occurred. Therefore, in the diagnosis should be detailed history and X-ray examination, if necessary, surgical exploration and pathological examination.
