Effect of the tumescent infiltration solution temperature on body temperature / 中华整形外科杂志

<p><b>OBJECTIVE</b>To evaluate the effect of tumescent infiltration solution temperature on core body temperature after liposuction.</p><p><b>METHODS</b>15 healthy female subjects were randomly divided into 2 groups to receive tumescent infiltration solution at 25 degrees C as group A, or at 37 degrees C as group B. All subjects were under epidural anesthesia. Vital signs, including core temperature, heart rate, respiratory rate and blood pressure, were monitored immediately, 1 hour, 2 hours, 3 hours, 4 hours and 8 hours after operation.</p><p><b>RESULTS</b>The core body temperature immediately, 1 hour, 2 hours and 3 hours after operation were (35.8 +/- 0.5) degrees C, (35.8 +/- 0.5) degrees C, (36.0 +/- 0.5) degrees C, (36.1 +/- 0.5) degrees C in group A, and (36.5 +/- 0.4) degrees C, (36.5 +/- 0.3) degrees C, (36.5 +/- 0.3) degrees C, (36.6 +/- 0.4) degrees C in group B, showing a significant difference between the two groups (P = 0.008, P = 0.008, P = 0.03, P = 0.033, respectively). There was no difference in body temperature 4 hours and 8 hours after operation and in heart rate, respiratory rate and blood pressure between the two groups (P > 0. 05).</p><p><b>CONCLUSIONS</b>The tumescent infiltration solutions at room temperature (25 degrees C) can decrease the core body temperature and increase surgical risk. It might not be good for rehabilitation. It is recommended to use tumescent infiltration solution at body temperature (37 degrees C) in liposuction.</p>

Application principles of hatchet skin flap for repairing tissue defect of cheek / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the design principles, clinical results and significance of hatchet skin flaps for repairing tissue defects in different parts of cheek.</p><p><b>METHODS</b>The area of cheek was divided into three parts, P(I), P(II) and P(III), with vertical lines through the medial canthus and lateral canthus. Different kinds of hatchet skin flaps were designed to repair tissue defects in different part of cheek. The hatchet skin flaps were performed in 29 cases with tissue defects in different part of cheek from August 2005 to August 2009. There were 17 male and 12 female, aged from 19 to 81 years, with a mean age of (45 ± 16) years. The size of tissue defect ranged from 1.5 cm × 1.5 cm to 2.5 cm × 3.5 cm. Patients' satisfactions were evaluated with a questionnaire in 5 aspects:color and texture match, scar, morbidity, and function after 6 months operatively.</p><p><b>RESULTS</b>All the flaps survived completely with good color and tissue match. The facial contour was not altered obviously. Six to eighteen months later, all scars were almost invisible. All 29 patients were satisfied with their results.</p><p><b>CONCLUSIONS</b>The hatchet skin flap is one of the versatile reconstructive methods for repairing of medium and small defects in the three parts of cheek. Defects in different part of cheek should be repaired individually with hatchet flap based on characters of natural lines.</p>

3-dimensional CT cephalometry before and after mandibular angle osteotomy and its clinical significance / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the change of skeleton structure and masseter after mandibular angle osteotomy and its clinical significance in preoperative design.</p><p><b>METHODS</b>3-dimensional CT cephalometry was performed before and after surgery in 18 cases of prominent mandibular angle.</p><p><b>RESULTS</b>Pre- and post-operative data were compared. Significant differences between the pre- and post-operative data were found in the mandibular angle, the distance between mandibular angle, length of ramus, ectropion angle of mandibular angle, triangle Go-Me-Go, the thickness, width and length of masseter.</p><p><b>CONCLUSIONS</b>It indicates the skeleton structure is changed and some kind of atrophy happens in the masseter after operation. So we suggest partial resection of masseter should be unnecessary for mandibular angle osteotomy.</p>

3-dimensional finite elements vitodynamics analysis for mandible after mandibular angle osteotomy / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the changes of mandibular vitodynamics in powerful bite working condition and impact working condition after mandibular angle osteotomy through 3-dimensional finit element analysis.</p><p><b>METHODS</b>A patient of prominent mandibualr angle without malocclusion was selected and underwent 3-dimensional CT before and after operation. The DICOM data of 3-dimensional CT were read by Mimics software and 3-dimensional images were reconstructed. Then the 3-dimensional images were changed into IGES format and imported into ANSYS10.0. The boundary constrained condition and pre-processing condition was setting in ANSYS10.0 software. The 3-dimensional finite element models were generated in ANSYS10.0. Solution process was running and most powerful bite working condition and impact working condition were simulated and calculated.</p><p><b>RESULTS</b>In static stress analysis, the stress peak and stress maximal value point of mandible were basically at equal pace in preoperative and postoperative models. In transience dynamic stress analysis, although stress discrepancies were found in part time point and some region of mandible between preoperative model and postoperative model, the direction and topography of main stress were basically at equal pace. Main stress distributed beside external oblique line and concentrates at the neck of condyle. There was no significant difference of stress conduction and distribution between preoperative and postoperative models.</p><p><b>CONCLUSIONS</b>Compared with preoperative model, postoperative model has different transduction phases of stress, but has almost the same tolerance extents of main stress.</p>

Comparison study of three methods for the treatment of microgenia / 中华整形外科杂志

<p><b>OBJECTIVE</b>To analyze the clinical results and complications of three methods for microgenia, including chin augmentation with silicone implant, bone autograft, and genioplasty.</p><p><b>METHODS</b>The advantages and disadvantages of the three methods for microgenia were assessed through 3-D CT reconstruction, X-ray and intraoperative observation during the second operation. The indications for each technique were also studied.</p><p><b>RESULTS</b>The frequently observed problems for chin augmentation with silicone implants were implant malposition, underlying bone absorption, periosteal reaction and undercorrection. Chin augmentation with bone autograft had a great long-term bone graft absorption which led to undercorrection. Genioplasty showed a satisfactory cosmetic result with no serious complication.</p><p><b>CONCLUSIONS</b>Chin augmentation with silicone implant is suitable for mild microgenia with a shallow mentolabial groove, but without facial vertical insufficient and facial asymmetry. Genioplasty can be used in all kinds of microgenia in any severity, especially those with deviated chin and facial asymmetry. Chin augmentation with bone autograft can't achieve good long-term result and should be applied prudently.</p>
