This study presents a comparative analysis of the open surgical and nonsurgical treatment of patients with bilateral condylar fractures. Sixty-seven (67) patients were treated, and the completed data on 55 patients were reviewed to compare both therapeutic modalities, which consisted of nonsurgical and surgical treatment in 37 and 18 patients, respectively. In the nonsurgical group, 23 patients (23/37, 62%) had normal mouth opening. Functional success rate was 79% (15/19) and 44% (8/18) in young adult patients (-29yrs) and older patients (30+yrs), respectively, and there was a significant difference of outcome between the two groups. In nonsurgically treated young patients with disorders, bilateral dislocation and existence of concomitant mandibular fractures were commonly observed. In the open surgical group, seven (7/11, 64%) young adult and three (3/7, 43%) older patients gained normal mouth opening, and no significant difference was observed. Additionally, there was no difference between non-surgical and surgical treatment in any category. Patients undergoing rigid fixation benefited from restoring maximum mouth opening, although there was no significant difference between the rigid and non-rigid fixation groups. Based on these findings, nonrigid fixation should be avoided, and rigid fixation might improve outcome in young adult patients with severe fracture pattern, such as bilateral dislocation and concomitant mandibular fracture. 相似文献

Salivary duct carcinoma (SDC) is a distinctive and aggressive neoplasm. The most frequent site of origin is the parotid gland, followed by the submandibular gland. SDC originating in the minor salivary glands, particularly in the ectopic glands within the mandible, is extremely rare. We describe a 62-year-old man with SDC in the mandible, who presented with a painless lump in the right submandibular region (later identified as lymph node metastasis) and ipsilateral mental nerve palsy. Histologic examination after ablative surgery revealed SDC originating in the mandible and cervical nodal metastases spreading to levels I-III. The patient remains alive 59 months after presentation as a result of postoperative full-dose irradiation and regular intensive chemotherapy using TXT, 5-FU, and CDDP. However, the patient has local recurrence and distant metastases to the lung and brain. In this report, we also discuss the specific diagnostic criteria and developmental theories of intraosseous salivary gland tumors. 相似文献

The activity of serum type IV collagen-degrading enzyme was measured in 21 patients with hepatocellular carcinoma, and the changes in the enzyme activity were investigated with respect to metastasis. The activity of serum type IV collagen-degrading enzyme did not increase until tumor invasion to the portal vein and intrahepatic metastasis were clearly detected ultrasonographically. Activities did not increase during the observation period in patients whose tumor grew slowly and did not invade the portal vein. Thus, the enzyme activity increases in relation to the metastasis of hepatocellular carcinoma and may be useful to detect ongoing metastases. 相似文献

This study aimed to evaluate postoperative long‐term liver restoration and splenic enlargement and their clinical significance in living donor liver transplantation. One hundred and sixteen donors who had donated livers more than 5 years previously accepted the invitation to participate in this study. The liver restoration rate and the splenic enlargement rate were calculated as the rate with respect to the original volume. The mean liver restoration rate was 0.99 ± 0.12 and older age was associated with a higher incidence for liver restoration rate <0.95 (P = .005), whereas type of donor operation was not. The donors with liver restoration rate <0.95 showed lower serum albumin levels than those with liver restoration rate ≥0.95. The mean splenic enlargement rate was 1.10 ± 0.16. Right lobe donors demonstrated higher splenic enlargement rate (1.14 ± 0.18) than left lobe/lateral segment donors (1.06 ± 0.13). In the donors with splenic enlargement rate ≥1.10, platelet count was not fully restored to the preoperative level. In conclusion, older age increases the risk for incomplete postoperative liver restoration, which may be associated with a decrease in albumin more than 5 years after donation. Right lobe donation poses a risk of splenic enlargement, which is associated with incomplete restoration of platelet count. 相似文献
