OBJECTIVETo investigate the application of three-dimensional CT(3D-CT) in the treatment of oblique facial clefts with mandibular outer cortex, including the surgical design and results assessment.

METHODSFrom Jan. 2003 to Dec. 2013, 22 cases with oblique facial cleft, who underwent mandibular outer cortex onlay bone graft were retrospectively studied. 3D images from CT data were reconstructed before operation for design. Then the mandibular outer cortex onlay bone transplant was performed to reconstruct the bone defect and cleft. 3D CT was performed 5-10 days postoperatively and 6- 12 months postoperatively to assess the facial symmetry.

RESULTSAccording to the results of CT measurement, the average volume of the orbital bone defects on the affected side decreased by(64. 6 ± 14. 4)% 5 to 10 days after operation. The average volume of the maxillary and zygomatic bone defects on the affected side decreased by(71.4 ± 15.7)% after surgery. After 6 to 12 months,the average recovery of the mandibular donor site was (57. 9 ± 13. 9)% of the removed mandibular outer cortex. The average absorption of grafted bones was(24.7 ± 25.6 )%. The average height difference between the centre of pupils on both sides before surgery was(3.76 ± 1.27) mm,which decreased to( 1. 15 ± 1.00) mm 5 to 10 days after surgery(P =0. 000) , and( 1.35 ± 1. 13) mm 6 to 12 months after surgery(P = 0. 003). The relapse may be caused by the absorption of the grafted bones.

CONCLUSIONS3D-CT can be used for preoperative design and postoperative assessment in the treatment of oblique facial cleft with mandibular outer cortex.

Objective High-density porous polyethylene(Medpor)has been widely used in chin augmentation in recent years.The study aimed to observe the outcomes of clinical use of high-density porous polyethylene implant in chin augmentation in contour plastic surgery of low face.Methods From 2005 to 2008,149 cases of chin augmentations intraorally with Medpor implants combined with were collected.121 of them received bilateral mandibular angle osteotomy and 28 cases received bilateral mandibular angle osteotomy and bilateral malar reduction simultaneously.They wre all females aged from 17 to 46 years.The patients were followed up for 6 to 36 months(average 24 months)and photographs were taken before and after operations.Clinical outcomes were observed and analysed.Resuits 145 patients(97.3%)were satisfied with their chin and contour of low face.2 patients (1.3%)were not satisfied with the projection of their chin,and 1 of them were admitted to take out the implant and received sliding advancement genioplasty.1 patient(0.7 0A)felt the implants was too large to some extent and was admitted to modify the implant.1 patient(0.7%)received genioplasty 6months after operation because of the deviation of the implant.20 patients(13.4%)felt numbness of the lower lip which gradually disappeared 1 to 3 months postoperatively.Complications such as infection,edema and extrusion,break of the implant were not found during the following period.Conclusions Medpor is an excellent biomaterial with good biocompatibility.Simultaneously chin augmentation with Medpor combined with bilateral mandibular angle osteotomy intraorally shows a good result in contour plastic surgery of low face.

Objective To investigate the short term effect of gastric bypass surgery for the treatment of nonobese type 2 diabetes mellitus and possible mechanisms. Methods The clinical data of 58 patients with nonobese type 2 diabetes mellitus who received gastric bypass surgery from March to August, 2009 were retrospectively analyzed. The levels of fasting plasms glucose (FPG), 2-hour postprandial plasma glucose (2h PG) and glycosylated hemoglobin (HbA1c) were dynamically monitored, and the insulin resistance index (HOMA-IR) and body mass index ( BMI) were calculated. All data were analyzed using variance of analysis and LSD test. Results Of the 58 patients, 48 (83% ) met the requirement of complete response criteria and stopped administration of hypoglycemic agents; 7( 12% ) had to use hypoglycemic agents, but the dose of the agents was lowered by 50% compared to that before surgery. The surgery was ineffective in 3 patients (5% ). The levels of FPG, 2h PG, HbAlc and HOMA-IR of the 58 patients showed a significant decreasing trend after surgery when compared to those before surgery (F = 67. 867, 50. 885, 78. 278, 572. 757, P <0.05), while there was no significant change of the BMI after surgery ( F = 3. 503, P > 0. 05 ). Conclusions Gastric bypass surgery has a good effect on nonobese patients with type 2 diabetes mellitus whose BMI was less than 25 kg/m2. The improvement of insulin resistance after the surgery might be the main reason.

An old male patient visited the hospital due to shortness of breath and palpitation for 6 h, with fever 3 days before and pump failure at admission. Having no risk factor of coronary diseases such as hypertension, diabetes mellitus and obesity, with ST-T changes and abnormal Q wave on ECC, the signs were compatible with those of acute anterior wall myocardial infarction, while the characteristics of cardiac biomarkers ( significant increase in Troponin I and creatine kinase's isoform, and normal creatine kinase) were not in accordance with those of acute myocardial infarction. Emergency angiography was performed, which indicated normal coronary artery, normal pulmonary artery and global systolic dysfunction of left ventricle. The diagnosis of acute severe myocarditis was established, and intra-aortic balloon pump (IABP) was employed to provide hemodynamic support. Severe myocarditis mimicking acute myocardial infarction may be fatal, and can be easily misdiagnosed. Careful analysis of clinical manifestations, early diagnostic angiography and possible IABP placement are important for the successful treatment.

Objective: To discuss the establishment of three-dimensional mirror image plane ofhemifacial microsomia. Methods: 32 cases of hemifacial microsomia from Jan. 2006 to Jan. 2017 were collected in our hospital. CT scanning was performed for all patients. Then, the deformity characteristics were summarized through three steps: 3D reconstruction, mirror and discrepancy analysis. Results: After statistical analysis, the stability of these three points was good. Clinical result showed that the patient′s appearance was greatly improved. Conclusions Using these three points to determine the mirror image plane is helpful to analyze the patient's facial features and facilitate the surgical design.

Objective To aesthetically evaluate the mandible,to position the gonion landmark of the aesthetic female with digital techniques and to establish three-dimensional mandibular measurements database of the aesthetic female.Methods 14 aesthetic volunteers were chosen by plastic surgeons and ordinary people based on the identical view of esthetic mandible.The heads were scanned by a spiral CT scanner,and the data were imported into Mimics 18.0 to generate the 3D skull images.Distance,angle and ratio measurements,which could represented the aesthetic characters of the mandible,were made on the images.All the data were transferred into the SPSS 22.0 software to perform statistical analysis.A two-tailed t test was used to compare the symmetry of bilateral mandibles.Dynamic database of aesthetic mandibles was established.The mean,standard deviation,standard error and 95％ confidence interval of data were calculated by statistical software automatically.Results The results suggested that the mean of aesthetic mandibular angle was 123.91°,and the mean of mandibular plane angle was 27.03°.The ratio between the mandibular body and ramus approximated to 2 ∶ 1,and the ratio of the distance between gonion and mental foramen to ramus was close to 1.4.Conclusions The study of mandibular esthetics contributes to positioning the new gonion accurately for patients with prominent mandibular angle and gonion reconstruction,and it can assist surgeons in surgical designing,simulating and performing.

Objective To establish a cranial bone defect model of goat and to study application in craniomaxillo-facial surgery.Methods Electron beam computed tomography (EBCT) scanner was used to scan goat'heads and faces in series and thin layers.Data of EBCT were input in workstation from digital inlet,and then to three-dimensional reconstruction with method of surface shadow.After final data were transformed to the files,the rapid prototyping machine was able to identify and establish the 3D model.Results The EBCT continuous thin-layer (1 mm) scanning data were passed to wave filter,falling coarse,distinguishing and collecting the outline,3D-reconstruction,curved surface reconstruction with CAD and the substance reconstruction.The final data were input into the laser rapid prototyping machine.Three-dimensional bionic cranium models were fabricated by machine in layer by layer manufacturing principle.Conclusions Establishment of the cranial bone defect model in the goat is very useful to the three-dimensional measurement,individualized reconstruction and basic and clinical research for the cranial bone defect.

Objective: To design the aesthetic new gonion and osteotomy line for patients with prominent mandibular angle patients using computer-aided techniques, and to investigate the application of three-dimensional digital planning in gonioplasty. Methods: From April 2016 to April 2017, 14 female patients with prominent mandibular angle underwent preoperative surgical design and surgical simulation using digital technology. Gonioplasty was performed under the guide of surgical templates, preoperative, surgical simulation and postoperative data were measured including bilateral mandibular angles, the height of ramus(Co-Go) and the length of mandibular body(Go-Me). Paired t test was used to compare the differences between surgical simulation and postoperative measurements. Results: Gonioplasty was performed in 14 patients successfully, and all were satisfied with their facial outcomes. The mandibular angle was improved from 113.86°±4.11° to 124.52°±1.26° on the left side, and 114.30°±4.01° to 124.29°±1.24° on the right side respectively. The average ratio of Go-Me/Co-Go was 2.011 on both sides after operation, which was very close to surgical planning. No significant differences were found between surgical planning and postoperative measurements with respect to mandibular angle or the ratio of Go-Me/Co-Go on both sides(P>0.05). The deviations between them were 1.00°±0.68° and 0.058±0.038 on the left side, and 0.85°±0.63° and 0.072±0.053 on the right side respectively. Conclusions Computer-assisted gonioplasty could improve the efficiency and accuracy of surgery, reduce the risk of surgical complications, and attain higher patients′ satisfaction.

Objective: To design a method of mandibular division for plastic surgery. Methods: From January 2009 to June 2017, 118 patients who underwent mandibular plastic surgery were observed, measured and analyzed. Combined with clinical experience, a new method of mandibular division was designed. The mandible was divided into right and left sides and each side was subdivided into five subunits (A, B, C, D, E). Area A is mandibular ramus upper 1/2 and mandibular coracoid area; Area B is mandibular lower 1/2 area; Area C is mandibular body area; Area D is chin area; Area E is mandibular angle. Results: The mandibles of 118 patients were divided according to the new method to obtain the characteristics of mandibular deformities and guide the design of the surgical plan. Conclusions The new method of mandibular division is concise and scientific, which is in favor of the diagnosis and surgical design of plastic surgery.
