Benefits of placing intra-aortic vacant guide wire on interventional treatment of aorto-ostial lesions / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the potential benefits of placing intra-aortic vacant guide wire on interventional treatment of aorto-ostial lesions.</p><p><b>METHODS</b>A total of 86 consecutive patients underwent percutaneous coronary interventions (PCI) for aorto-ostial lesions were randomly divided into conventional treatment group (group A) and intra-aortic vacant guide wire group (group B). Standard PCI techniques were applied in group A and an intra-aortic vacant guide wire was placed outside the guiding catheter before the guiding catheter into the target coronary artery in group B on basis of standard PCI techniques. The number of guiding catheter, guide wire, X-ray exposure time, total PCI time, the incidence of pressure drop and malignant arrhythmia, contrast agent dose and the number of failure cases were compared between the two groups.</p><p><b>RESULTS</b>The number of used guide wire was similar between the groups (2.0 ± 1.1 vs. 2.2 ± 0.4, P > 0.05) and the number of guiding catheter used was significantly more in group A than in group B (2.3 ± 1.1 vs. 1.3 ± 0.5, P < 0.01). The X-ray exposure time (18.8 min ± 6.9 min vs. 14.2 min ± 5.7 min, P < 0.01) was significantly less in groups B and the total PCI time (31.2 min ± 8.1 min vs. 20.1 min ± 4.5 min, P < 0.01) and the amount of contrast agent (193.5 ml ± 25.4 ml vs. 130.6 ml ± 32.8 ml, P < 0.01) and the frequency of pressure drop (19 cases vs. 2 cases, P < 0.01) were all significantly higher in group A than in group B. Incidence of malignant ventricular arrhythmia (8 vs. 0) and procedure failure (6 vs. 0) was also higher in group A compared to group B.</p><p><b>CONCLUSION</b>The method of using Intra-aortic vacant guide wire is associated with reduced risk and improved success rate of PCI for aorto-ostial lesions.</p>

Cryotherapy combine with pingyangmycin for the treatment of venous malformations / 中华整形外科杂志

<p><b>OBJECTIVE</b>To observe the therapeutic effect of 120 cases venous malformations treated by cryotherapy combine with pingyangmycin.</p><p><b>METHODS</b>Pingyangmycin was injected into venous malformations and cryotherapy with liquid nitrogen was followed immediately.</p><p><b>RESULTS</b>Cure rate was 77.5%, incomplete cure rate was 17.5% and efficiency rate was 5%.</p><p><b>CONCLUSIONS</b>The method of cryotherapy combine with pingyangmycin injection to treat venous malformations has good effect.</p>

Clinical study of surgical treatment of ankylosis of temporomandibular joint / 中华整形外科杂志

<p><b>OBJECTIVE</b>To analyze the clinical feature of temporomandibular joint (TMJ) ankylosis and to investigate the advantage and disadvantage of all kind of surgery methods of TMJ ankylosis for supplying references to the treatment of TMJ ankylosis.</p><p><b>METHODS</b>Aetiology, sex, age at time of treatment, clinical features, radiographic findings, surgical treatment was reviewed and analyzed.</p><p><b>RESULTS</b>Trauma (66.86%, n = 117) and infection (24.57%, n = 43) were the primary causes of TMJ ankylosis. The 10 approximately 19 years age group (44.57%, n =78) occupied the highest frequency in five age groups, one hundred and fourteen (65.14%, n = 114) of the patients presented with lateral ankylosis. They were carried out different surgery method according to their difference of age, aetiology, and so on.</p><p><b>CONCLUSIONS</b>The person at 10 approximately 19 years old had the more feasibility of TMJ ankylosis than others. Trauma was the commonest cause of ankylosis. Different surgical method should be choose according to the different patient.</p>

Function of disk reposition in the treatment of traumatogenic temporomandibular joint ankylosis / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the method and results of disk reposition in the treatment of traumatogenic TMJ ankylosis.</p><p><b>METHODS</b>In 19 cases of traumatogenic ankylosis of TMJ, the dislocated disks were repositioned during anthroplasty. In the operation, the dissection of dislocated disk was performed carefully around the TMJ. The disk was repositioned to its anatomic location over the top of condylar stump, then the lateral aspect of the disk was sutured to the soft tissue of zygomatic root.</p><p><b>RESULTS</b>At the last follow-up examination, interincisal opening distance ranged from 24 to 43 mm in all cases (mean 32.63 mm), which approached or reached the normal level. No recurrence and TMJ symptom were found during the period of follow-up.</p><p><b>CONCLUSIONS</b>The disk repositioning in treatment of traumatogenic TMJ ankylosis is a feasible and effective approach to reconstruct the structure and function and prevent recurrence.</p>

A clinical investigation on the surgical approach and fixation in operative treatment zygomatic fractures / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the effect of soft tissue incision and rigid internal fixation in the treatment of zygomatic fracture.</p><p><b>METHODS</b>70 cases with zygomatic fracture were entered into the study. The clinical data of 65 patients who were performed operations in the treatment were analyzed. The study focused on the incision, number and locations of Titanium plate. The facial contour, reduction,fixation, healing of incision, facial bisymmetry and complications of the operation were followed up 3 - 24 months after surgery.</p><p><b>RESULTS</b>All the incisions were primary healing. Clinical and radiologic assessment of reduction was symmetric and stable in 91.5% of all cases, asymmetric in 8.5% of all cases. Subcutaneous hematoma happened in 5 cases, Ti plate exposure 1 in case, scalp scar width was more than 0.5 cm in 6 cases, frontal part or scalp paresthesia 8 cases.</p><p><b>CONCLUSIONS</b>Coronal scalp incision has advantages such as good exposure, precise removal of the bone block and good symmetry of both sides. RIF can improve the stability of fracture, promotes fracture healing and guarantees the rehabilitation of zygomatic complex. direct reduction and rigid internal fixation with Titanium microplate or miniplate are satisfactory in zygomatic fracture.</p>

Management of disk displacement with condylar fracture / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate clinical features of disk displacement during the course of condylar fracture and to explore the techniques of disk reposition and suturation.</p><p><b>METHODS</b>32 patients (10 females and 22 males) who had disk displacements with condylar fractures were followed up. Reduction and reposition of the dislocated disks simultaneously with fixation of fractures were performed. 7 patients underwent intermaxillary fixation with elastic bands for 1 to 2 weeks.</p><p><b>RESULTS</b>The occlusions were satisfactory in all cases but one for the reason of ramus height loss. No TMJ symptom was found when examined 3 months post operation.</p><p><b>CONCLUSIONS</b>Anterior disk displacements were most occurred with high condylar process fractures. Surgical reposition and suturation of disk play an important role for the later TMJ-function.</p>
