Objective To observe the clinical effect on cervicogenic headache (CEH) of pulsed radiofrequency stimulation (PRF) applied to the C2 dorsal root ganglion combined with nerve block.Methods A total of 78 cases diagnosed as CEH were randomly divided into a combined treatment group,a PRF treatment group and a nerve block group.The combined treatment group was given both PRF applied to the C2 dorsal root ganglion and blocking therapy.The other two groups were given only one treatment or the other.All the treatments were once weekly for 3 weeks.Before treatment and 1,3 and 6 months after treatment,all of the patients' headaches were evaluated using a visual analogue scale (VAS).Results At 1,3 and 6 months after treatment,the average VAS scores of all three groups had decreased significantly.The VAS ratings dropped the most in the combined treatment group,followed by the PRF group and then the nerve block group.All the intergroup differences were statistically significant.The combined treatment group's cure rate (88％) was significantly better than that of the PRF group (81％),which was significantly better than that of the nerve block group (54％).Conclusion Combining PRF applied to the C2dorsal root ganglion with nerve block therapy has a synergistic effect on CEH.The curative effect of the combined treatment was better than either PRF or blocking alone.

Objective To investigate the reconstructive effect and method on breast deformation after polyacrylamide hydrogel injection for breast augmentation.Methods Sixty patients underwent B type ultrasonic and MRI examination for confirmation of breast deformation after removal of polyacrylamide hydrogel injection and clear distribution level of the injection material and surrounding tissue infiltration.According to skin elasticity,breast subcutaneous layer,glandular layer and pectoral muscle layer,then placed in the suction apparatus with injection of normal saline and completely sucked out and clear the injection material.Based on the wishes of patients and tissue damage,divided into Ⅰ or Ⅱ prostheses implanted and provided appropriate treatment Results Within 3 months to 3 years visiting,breast shape was good.Prosthesis had no herniation,without infection.Bilateral breasts were symmetry without capsular contracture.Conclusions Reconstruction of breast deformation after polyacrylamide hydrogel injection for breast augmentation can improve breast shape and achieve satisfactory effects.

Objective To explore the methodology of skin flap muscle flap (double flaps) and and effect of the double flaps on eyelid bag blepharoplasty.Methods Through lower eyelid incision,skin flap and muscle flap were formed,orbicularis muscle and orbital septum separated between the skin and flaps,direct access to the inferior orbital rim depression.Arcuate edge of the orbicularis muscle was fully stripped and released,especially the orbicularis muscle at the inferior orbital rim periosteal surface.The orbital fat was released,sutured below the inferior orbital rim periosteal surface.The orbicularis muscle flap was designed,lift and fixed to enhance midface to achieve the rejuvenation effect in the lower eyelid region.Results The 36 patients treated had no hematoma and flinch in the lower eyelid.Within 3 to 18 months follow-up,there were no ectropion,and facial nerve damage and other complications.Conclusions Double-flap is a feasible method as it can effectively enhance midface rejuvenation and correct eyelid bags deformity.

Objective To investigate the clinical indication and effect of instant reconstruction of breast after removal of polyacrylamide hydrogel injection for breast augmentation.Methods Patients had breast ultrasound,MRI check before operation,to define the distribution and level of the injections and tissue infiltration.Depending on tissue degree,capsule integrity and breast degeneration situation,three different methods were chosen,including implantation of silicone gel underneath the breast,pectoralis major or dual-plane.Results 56 patients' incision healed well.Follow-up for 6 months to 3 years showed that breast shapes were good without scars,prosthetic herniapsular,capsular contracture and other complications.Conclusions Instant reconstruction of the breast after removal of polyacrylamide hydrogel injection can improve breast shape and get satisfied effects.

Objective To study the methods and clinical effects of joint expansion of double fascia flaps wrapping the Medpor to perform full-ear reconstruction on congenital microtia deformity.Methods 60 patients with congenital microtia deformity were selected.including 22 left ears and 38 right ears.Majority had loss of ear auricle or only partial earlobe.Phase Ⅰ procedures included:temporal-parietal branch was used for the vascular pedicle,and mastoid area behind the ear was moved and expanded for fascia flap.Phase Ⅱ included:the joint expansion of double fascia flap wrapped Medpor to do full-ear reconstruction.Results Flaps survived and no complications for all 60 patients.Reconstructed ears had lifelike appearance and clear anatomical structures.Auriculocephalic angulars positions and sizes were consistent with the healthy ears.None of them had exposed prosthesis and scar contraction.Three-dimensional shapes were good.Conclusions Joint expansion of double fascia flap wrapping Medpor could avoid the chest wall deformity and exposed prosthesis.The fine structure of the reconstructed ear is satisfactory.

Objective To study the methodology and effect of auricle reconstruction with prefabricated expanded fascial flap in temporal and parietal area and skin flap in mastoid area, covered on the Medpor support. Methods Thirty cases of congenital vestigial auricle were involved in this study. The operations were divided into two stages: in the stage I,the temporal and parietal superficial fascia flap was cut with a vascular pedicle in the parietal and temporal superficial area, which was implanted under the skin of mastoid, and then both layers of those were expanded at the same time; in the stage II, this fascial skin flap was cut down and covered on the whole Medpor support to rebuild the man-made auricle. Results Thirty cases were successful after following-up for 6 months to 3 years. Their auricle shapes were vivid; their skin color was normal, and it had no any difference from all around skins, or no any appearance of the support. Conclusions With best understanding the biological characteristics of the Medpor support and choosing the suitable procedures and using the prefabricated expanded support, we could minimize the surgical complications in this operation. The results show that this procedure is satisfactory, without any necrosis of flap, swelling of contour, or appearance of the support. The combination of two flaps is the best method for the auricle reconstruction.

Objective To study the methodology and results of the auricle repair with expanded skin flap in mastoid process area and Medpor support in children with congenital malformation.Methods Thirty cases of congenital malformation were enrolled with age ranged from 5～16 years old.Whole auricles were all reconstructed with an expanded skin flap in mastoid process area and Medpor support.Resuits In all successful cases.their repaired auricles had the natural complexion and profile,and the positions were symmetric with healthy one,but in 2 cases(age group of 11-16 years),the expanded skin flap had less skin grafting.Conclusion It is suggested that optional operation time might be selected before 10 years old,because their psychological trauma could be avoided owing to microtia and in that age the size of the expanded flap is larger enough to reconstruct the ear as their auricle iS well-developed.

Objective:To explore the effect of combined orbicularis muscle double stitch operated on blepharoplasty.Methods:A total of 90 patients, 79 females and 11 males, aged 18-49 years, were treated by using combined orbicularis muscle double stitch procedure, that is, to fix upper lifting muscle, to remove partial fat, and to perform blepharoplasty.Results:All 90 cases＇ incisions were healed at the first phase, no obvious swelling and bleeding. Within 3-24 months follow up, all patients＇ upper eyelids were significantly improved. The skin was smoothy when closing eyes, and eyelash was up when opening eyes, and arc was natural and satisfactory.Conclusions:This method can improve the shape of the upper eyelid swelling and get long-lasting and stable physiological eyelid.

Objective: To explorea long-term effect of in situ artificial anal reconstruction using five-combined-operation technique after lower rectal cancer resection. Methods: After miles operation, 60 patients suffered with lower rectal cancers underwent in situ artificial anal reconstruction using five-combined-operation technique, which included internal and external anal sphincter, rectal flap, rectal angle, and anoperineal reconstruction. Results: All cases in this study were performed successfully, with primary healing in the wounds. Awareness of defecation had reoccurred in all cases since 1 week postoperatively and self-control of defecation had been regained since 3 weeks postoperatively with formed stool excreted once or twice a day. Long-term follow-ups: ①In 95% cases, rectal controlled discharge time was longer than 2 minutes, which was significantly higher than that of sphincter reconstruction group as a control(P<0.05). ② Five-year survival rate reached to 88%, which was significantly higher than that of the control group(P<0.05). Conclusions Anal reconstruction using five-combined operation method after Miles operation could be a safe and effective surgical procedure, which could completely cure tumor, and improve patients′ life quality and long-term survival rate.
