作者为评价内窥镜诊断颌下腺导管疾患的作用,先用内窥镜观察6例正常受试者的正常颌下腺导管壁,接着对12例有导管阻塞症状的患者作内窥镜检查,并与X线平片、涎腺导管X线造影、超声检查等诊断方法作比较。内窥镜检查均在门诊完成,不需局麻或镇静,操作时先用探针扩张颌下腺导管开口,再将外径0.8mm或1.0mm的硬镜或软镜插入导管内。结果,内窥镜检查发现导管结石的5例中,4例涎腺导管造影示充盈缺损,超声检查示强回声结构,另1例无提示。内窥镜证实阻塞原因为分泌栓或导管狭窄的7例中,
In order to evaluate the role of endoscopy in the diagnosis of submandibular gland duct disorders, we first examined the normal submandibular gland duct wall of 6 normal subjects with an endoscope, followed by endoscopy in 12 patients with ductal obstruction symptoms and with X Line plain film, salivary gland duct radiography, ultrasound examination and other diagnostic methods for comparison. Endoscopy are done in the clinic, without local anesthesia or sedation, the first expansion of the operation of the submandibular catheter catheter opening, and then the outer diameter of 0.8mm or 1.0mm hard mirror or soft mirror into the catheter. Results, endoscopy found catheter stones in 5 cases, 4 cases of salivary gland duct angiography showed filling defects, ultrasound showed strong echo structure, and the other 1 case without hint. Endoscopic confirmed the cause of obstruction or septal suppository catheter stenosis in 7 cases,
