Objective To investigate a safe and effective method to correct the over rotation of nasal tip in rhinoplasty. Methods 16 cases, including 11 of primary and 5 of secondary over rotation of nasal tip, were corrected with strut grafts using autologous cartilage or combined with Medpor to reconstruct the supporting structures underneath to improve the upward and forward strength of the nasal tip in order to increase the nasal height and to correct the over rotation of of nasal tip. The shield and cap grafts were also used for the patients whose nasal tip were too low, with vertical dome division technique. Results 16 cases were corrected satisfactorily, the nasal lip angles were normal and there were no complications by follow-up from 6 months to 1 year. Conclusion It is necessary to provide powerful forward and upward strength to correct the over rotation of nasal tip effectively and safely, and proper cartilage grafts can im-prove the height of the nasal tip and correct the over rotation of the nasal tip further.

Objective To improve survival rate of hair follicle after hair-bearing scalp minigrafting and to investigate the role of microsurgery in this procedure. Methods From 1990 to 2003, 156 cases suffered from male pattern baldness (MPB) and cicatrical baldness (CB) received hair-bearing scalp minigrafting. Moreover microsurgical technique was applied to this procedure. Among of them, the largest alopecia zone was about 12.5 cm ?15 cm. Results Survival rate of transplanted hair follicles was 95% (MPB) and 89% (CB) respectively. Baldness never occured in the former alopecia zone. Survival rate of transplanted hair follicles in CB was significantly higher than that of the former reports. There were 2 cases with abnormal figure of hair margin and 4 cases with unsatisfactory hair direction in hair grafted zone. Hematoma occurred in 2 patients who had no negative effects on hair follicle after hematoma were cleaned. The other cases all obtained satisfactory postoperative appearance. Conclusions Hair-bearing scalp minigrafting, combined with microsurgery technique, can improve survival rate of hair follicle after hair transplantation. Preoperative design, choice of indication and anesthesia, etc. are very important, too.

Objective To explore an epicanthoplasty with good effect and small scar. Methods A V shape incision was designed in medial canthus and the two lines: point A is the top point of medial canthus and point A' is the top point of new medial canthus. The length of line AA' is about 4 to 8 mm according to the medial canthus and th incision is Y shape, and then Y-V epicanthoplasty is raised and enlarged. Results From January 2005 to December 2008, 98 cases were treated with this method to eliminate the medial epicanthal fold of the upper eyelid with simple procedures. Scarring of the medial canthal area had not been a problem with this technique because we designed incisions along the eyelashes and skin-mucosal junctions. By raising the point of new medial canthus to physiological position the angle of medial canthus was enlarged to reveal a lacrimal lake. Conclusion This technique is a simple, easy procedures with no visible scar.

Objective To investigate the application of the parietal branches of superficial temporal artery island flap in the complex scalp defects.Methods A parietal branches of superficial temporal artery island flap on the ectatic scalp flap was designed to repair the complex scalp defects in 25cases and the repairing effect was observed.Results The island flaps were survived completely in 24patients,in which 1 patient had partial necrosis because of the flap tension was too large,but healed after local dressing and debridement.After followed up 6～ 12 months,the color and texture of the flap were the same to the surrounding normal scalp,and the shape was satisfactory.The flap donor site of hair growth was good,with well healing and no obvious complications.Conclusions The parietal branches of superficial temporal artery island flap can repair the complex scalp defects with the flexible flap design and movement.The flap survives well and the repair area is large.The flap and the surrounding scalp connects good.Therefore,it is a good method strongly recommended for small area complex scalp defects repair in clinics.
