Radiographic Study of Sialolithiasis on Objective Evaluation of Sialography.

探讨涎腺造影和x线平片检查对涎腺疾病诊断的意义。得到了以下结果：1。研究的临床资料包括1978 -1989年在大阪牙科大学口腔放射科诊断的449例涎石症患者。腮腺涎石症7例。涎石症的发生在两性之间大致均匀（男性：女性=222:220），诊断时患者的平均年龄为40.2岁。右侧：左侧=222:220，下颌下导管及腺区无左右差异。涎石症的特征性症状是唾液绞痛和唾液腺肿胀。242例（54.8%）出现症状。2.结石无明显症状，一般x线检查发现者多为偶发者79例（17.9%）。对122例患者进行了唾液造影检查，探讨了唾液造影的疗效及x线平片检查的意义。x线平片可以通过轴位和侧位斜位咬合投影近似确定唾液结石。此外，通过触诊获得的信息也有助于确定。涎腺造影对96例（78.7%）患者的判断有效，对涎腺组织状况和涎结石位置的判断有效。测量涎石症和正常颌下腺复杂结构涎谱的变化。分形维数分别为1.22和1.29。可以设想以结构复杂相似图的变化作为客观评定的指导，利用分形函数进行测量。我们认为，在临床表现和组织病理表现对比上，它在实际应用和准确性方面要比现在的形式有所提高。少

We carried out examination about the significance to diagnosis of sialography and plain radiographic examination in diseases of salivary glands.The following results were obtained :1. The material in the clinical part of the investigation consisted of 449 patients with sialolithiasis, diagnosed in Department of Oral Radiology, Osaka Dental University, during 1978 -1989. Patients with the sialolithasis of parotid gland were 7cases.a. The occurrence of the sialolithiasis is approximately evenly between the sexes (male : female=222 : 220), and the mean age of the patient at the time of diagnosis was 40.2 years.b. There was not the right and left difference in submandibular duct and gland region (right side : left side =222 : 220).c. The salivary colic and swelling of salivary gland was characteristic symptoms of the sialolithiasis. The symptom presents in 242 cases (54.8%). The stone presents no remarkable symptoms and almost it found by general radiographic examination by chance were 79 … More cases (17.9%).2. It examined about the efficacy of sialography and the significance of plain radiographic examination, about 122 cases that carried out sialography.a. Plain radiographic examination was able to decide approximate determination of salivary calculus by using axial and lateral oblique occlusal projection. Also, even the information by palpation became to help concerning the determination.b. Sialography was useful in judge of 96 cases (78.7%) and the sialograms were effective with condition of salivary gland tissue and determination of location of salivary calculus.C. It measured changes of complicated sialograms of structures of sialolithiasis and normal submandibular glands. The results of fractal dimension was 1.22 of sialolithiasis and 1.29 of normal gland. conceivable that be used changes of complicated sialograms of structures as a guideline of objective rating and carries out measuring by using fractal function.We are thinking that it wants to improvement as be used practically and be exact than a form now on clinical findings and histopathological findings contrasted.
