Reconstruction of anterior auricular defect with postauricular island / 中华医学美学美容杂志

Objective:To investigate the clinical effect of postauricular island flap in reconstruction of anterior auricular defect.Methods:Twelve patients with auricular tumors were retrospectively analyzed in the Department of Aesthetic Plastic and Craniofacial Surgery, the First Affiliated Hospital of Xi'an Jiaotong University. After the tumors were completely removed, the skin defects were repaired with retroauricular island flaps, and the clinical results of the flaps were observed.Results:All the twelve postauricular island flaps were survived postoperatively. One of the flaps had the disorder of blood supply. After puncture with the needle, the congestion was drained out and the flap survived finally. During 1 to 2 years' follow-up, all patients were well satisfied with the surgical results.Conclusions:The posterior auricular island flap in reconstruction of anterior auricular defect has the advantages of simple and easy operation, high survival rate, small scar in the donor area and good aesthetic effect, which is worthy of clinical promotion.

Surgical treatment of pediatric mandibular fractures / 中华医学美学美容杂志

Objective To explore the effectiveness of the individualized surgical fixation for the treatment of mandibular fractures in children.Methods The individualized mandibular fixation methods were used to treat mandibular fractures in 85 children in Department of Plastic and Reconstructive Surgery in Xijing Hospital from April 2010 to July 2015.Depending on the fracture types and 3D pre simulation with stress and tension band fixation,six methods of treatment were used,including titanium plate,titanium plate-dental arch bars,biodegradable plate-dentalarch bars,biodegradable plate-occlusal splint,occlusal splint,and anchorage devices.Postoperative occlusal relationship,mouth opening and masticatory function were evaluated.Results Fixation of titanium plate was used in 10 cases,titanium plate-dental arch bars in 25 cases,biodegradable plate-dentalarch bars in 20 cases,biodegradable plate-occlusal splint 15 cases,individualized occlusal splint in 3 cases and anchorage devices in 12 cases.The treatment outcomes were good in the combined methods of open reduction with personalized fixation for children with mandibular fractures,and the reduction was satisfactory.Occlusal relationship had a good recovery after operation.Eating and functional training started earlier in these pediatric patients after operation.Conclusions For pediatric mandibular fractures,open reduction and fixation with appropriate methods can lead to favorable anatomic morphology and occlusion relationship.The application of 3D imaging technology in analyzing the fracture and showing tooth germ in the jaw helps the improvement of surgical efficiency and avoidance of unwanted tooth germ injuries.Personalized dental arch bar and splint provide good strength for external fixation or assist fixation on strain band.

Clinical efficacy of novel ‘umbrella’ autogenous graft in secondary cleft rhinoplasty / 中华医学美学美容杂志

Objective To observe the effects of a novel type ‘umbrella’ graft in secondary cleft rhinoplasty.Methods 38 secondary cleft patients with moderate to severe nasal deformity that were older than 16 years in our department from September 2013 to March 2016 were received rhinoplasty with novel type ‘umbrella’ graft.Nasal augmentation and piriformaperture filling with autologous rib cartilage was applied in patients with saddle nose or nasal base depression.The appearance and patient's satisfaction were assessed at 6 months after surgery.Results There were no complications such as infection,hematoma and graft exposure in all 38 patients with rhinoplasty.The nasal tip,dorsum,nostril and nasal base were improved significantly 6 months after surgery.Especially the nasal tip and nostril,most of them,became almost normal.The patients' self-evaluation of the appearance and function were satisfying.Conclusions The novel type ‘umbrella’ graft can improve the deformity of cleft nose significantly,especially the appearance of the nose tip and nostril,which is a reliable method.

Clinical efficacy of repair for defect after xanthelasma removal with a subcutaneous pedicle flap based on the orbicularis oculi muscle / 中华医学美学美容杂志

Objective To study the method and effect of subcutaneous pedicle flap based on the orbicularis oculi muscle in the treatment of xanthelasma.Methods According to the situation of xanthelasma and the soft tissues of upper eyelid,two new double-folds eyelid was designed.The soft tissues (including the skin and muscle) between two lines were intended to form a subcutaneous pedicle flap based on the orbicularis oculi muscle.Then,after the excision of xanthelasma from the surface of orbicularis oculi muscle,the flap was transferred to the defected site.Finally,a new double-folds eyelid was made.Results 13 cases with 25 sides were treated with a follow-up period of 3-6 months.All flaps were survived with good functions and the appearance of upper eyelids were satisfactory.Conclusions Subcutaneous pedicle flap based on the orbicularis oculi muscle is a reliable option for the treatment of xanthelasma.It has the advantages of abundant blood supply,convenience and effective.

Repair of cervicai cicatricial contracture with cervico-shoulder island skin flap / 中华医学美学美容杂志

Objective To explore a better method to repair cervical cicatricle contracture deformity.Methods The cervicai cicatrical contraction deformity was repaird by the cervico-shoulder island skin flap with blood supply crossing and abundant anastomotic branches of the neck-shoulder blood vessels. After removing the cervical scar, the flaps were designed according to the size of the wound to be repaired, and the clinical anatomy of crossing and abundant anastomotic branches of the neck-shoulder blood vessels. The secondary wound of donor site was closed directly if the donor region was small, or closed by skin graft. Results Sixteen patients in this clinic were operated with this method, and venous return dysfunction occurred in 1 case, but blood circulation was improved after treatment. All the flaps survived with good appearance and texture. The extensive flap was created and transferred to the anterior neck by one stage without pre-expansion which met some patients'requirement of repairing cervical cicatricle contracture deformity. Conclusion The cervico-shoulder island skin flap, with abundant blood supply, is a new method to repair cervical cicatricle contracture deformity.
