Transposition of orbital fat and orbicularis muscle flap over the orbital rim for correction of lower eyelid pouches complicated with lacrimal groove deformity / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce the experience in the treatment of lower eyelid pouches orbital rim.</p><p><b>METHODS</b>An incision was made along the margin of lower eyelid and dissection was performed under the orbicularis muscle to expose the orbital septum and periosteum of lower orbital rim. The fat released from orbital septum was transposed just below the lower orbital rim and fixed on the periosteum. If lacrimal groove deformity was not corrected completely, the musculocutaneous flap, which may be excised beside the incision, was kept to correct the deformities further with only the muscle portion.</p><p><b>RESULTS</b>72 cases with lower eyelid pouches complicated with lacrimal groove deformities were treated with transposition of orbital fat and orbicularis muscular flaps. Satisfactory results were achieved in all the patients after a follow-up period of 3-6 months.</p><p><b>CONCLUSION</b>It is an effective and feasible technique to correct lacrimal groove deformities with transposition of orbital fat and orbicularis muscular flaps.</p>

Preliminary clinical study on the treatment of severe infantile hemangioma with high-dose propranolol in China / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical results of the treatment of severe infantile hemangioma with high-dose propranolol in Chinese.</p><p><b>METHODS</b>56 cases with severe infantile hemangioma were treated with propranolol. Clinical evaluation, electrocardiography, and experimental examination of liver function and heart function were performed before treatment. The daily dose of propranolol was increased from 1 mg/kg at the first day to 1.5 mg/kg at the second day, and to 2 mg/kg at the third day. The propranolol was given twice a day. The treatment was lasted for six months. The patients were visited every month.</p><p><b>RESULTS</b>The lesion color was changed after 2-4 days of treatment in all the cases. All the lesions were dramatically improved after one month of treatment. The ulceration were healed, except one case. Until now, complete regression was achieved in 10 cases and marked improvement in 46 cases. Side effects were happened in 3 cases, including one case of abnormal liver function, one case of CK-MB increase and one case of continuous increase of CK-MB, LDH, ALT, GGT.</p><p><b>CONCLUSIONS</b>High-dose Propranolol is very effective in the treatment of infantile hemangioma with minor side effects and short disease period. It might he used as the first-line treatment for infantile hemangioma.</p>

Monobloc distraction osteogenesis and cranial vault remodeling in a pediatric patient with severe Crouzon's syndrome / 中华整形外科杂志

<p><b>OBJECTIVE</b>To report the treatment of a case of severe Crouzon's syndrome using monobloc distraction osteogenesis and cranial vault remodeling.</p><p><b>METHODS</b>Through intra-and extra-cranial approach, monobloc osteotomy was performed and external distractor was placed. Distraction began on the 7th postoperative day at a rate of 1 mm a day, two times a day. The distractor removed after consolidation for 4 months.</p><p><b>RESULTS</b>The distraction distance attained 20 mm. The exophthalmos and cross bite were corrected completely. The severe obstructive apnea improved markedly.</p><p><b>CONCLUSIONS</b>Monbloc distraction osteogenesis and cranial vault remodeling are effective and safe procedure for Crouzon's syndrome.</p>

Research and clinical application of computer-aided design of craniofacial prosthesis using mirror technique / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the feasibility of creating a 3D-CAD model of craniofacial prostheses through mirror technique to repair the unilateral craniofacial defects and restore craniofacial symmetry.</p><p><b>METHODS</b>Patients with unilateral craniofacial defects underwent spiral CT scanning. CAD3-D image was reconstructed ad 3-D CAD model of craniofacial prosthesis was created with mirror technique, Boolean operation and rapid prototyping technique. Then the prosthesis made of bioactive artificial bone was made through plaster cavity block.</p><p><b>RESULTS</b>15 cases were treated with no complications. Good symmetry was achieved after operation.</p><p><b>CONCLUSIONS</b>Designing the craniofacial prosthesis with mirror technique guarantees excellent functional and cosmetic results for repairing the unilateral craniofacial defects.</p>
