Objective To explore the comprehensive approach of rhinoplasty using autologous costal cartilage,and to observe the outcome and summarize the possible complications.Methods A 6-7 cm long costal cartilage was taken out mostly from the 6th or 7th rib and then divided into several parts and shapes.A lancet shaped piece was used for dorsal augmentation,several cartilage bars for collumellar elevation and nasal tip elongation.Comprehensive structural rhinoplasty was then done with open rhinoplasty incision.Results 52 patients were treated with this method and satisfying aesthetic contouring of the nasal tip and dorsum was achieved.Among these patients,no such complications as implant extrution or dislocation,cartilage distortion,pneumothorax,hemothorax,infection or hemotoma were observed.The scar on the donor site was not obvius.Conclusions Costal cartilage can meet the demands of patients who consider prosthesis as an unacceptable option.For secondary revision rhinoplasties,costal cartilage provides sufficient materials to ensure a promising outcome with lower risk of infection and other complications.

Objective To employ autologous septal cartilage grafting as a new method of elongating the nose and adjusting the nasolabial angle in order to correct the deformities of short nose and bulbous tip.Methods A set of techniques,including,yet not limited to,releasing and sculpturing of the alar cartilages,harvesting of septal cartilages and carving them into L shape and cap-like shape for transplant,moulding the soft tissue envelop with buried through and through sutures etc.were used to lengthen the nose and modify the tip.Results From 2004 to now,the new technique had been applied to 345 patients with short nose and bulbous tip.Follow-up ranged from 6- 48 months,satisfactory outcomes were obtained.Conclusions The new technique adopted by the author in which autologous septal cartilages are settled to the anterior angle of the nasal septum and between the domes of alar cartilages has been proved to be a viable and reliable way to lengthen the nose.Further advantages of this technique include the easiness of harvesting grafts,minimal injury,rare complications of infection and rejection etc.

Objective To observe the effect of hydrocolloid dressings with instant ice compress on the healing process,postoperative pain and efficacy of patients with acne scar treated by 2940 nm erbium pixel laser.Methods We selected 60 patients with acne scar from November 2012 to June 2014 treated by the erbium pixel laser.They were randomly divided into two groups:hydrocolloid dressings with ice compress after treatment were used in observation group (n=37)and postoperative wound dry were kept in control group (n=23);pain,duration of burning,erythema duration,efficacy,decrustation time,postoperative complications were evaluated and quantitatively analyzed.Results Compared with the control group,the application of hydrocolloid dressings with ice compress group (observation group) received less postoperative paim postoperative VAS pain score was (5.81± 0.64) in observation group and (6.09±0.69) in control group;duration of burning was shorter:(1.86± 0.75) h in observation group and (3.65±0.93) h in control group;duration of erythema was shorter:(2.27±0.73) d in observation group and (3.52 ±0.79) d in control group;decrustation time was shorter:(5.76± 1.06) d in observation group and (8.09±0.95) d in control group;postoperative complications were reduced:(5.4％,2/37) in the observation group and (30.4％,7/23) in the control group,with statistically significant difference (all P＜0.05).The differences were not statistically significant in the intraoperative VAS score and the curative effect.Conclusions The application of hydrocolloid dressing with instant ice compress after erbium pixel laser in the treatment of acne scar can effectively reduce postoperative pain and burning sensation,shorten the duration of erythema and crusting time after operation.It also reduces the incidence of complications.

Objective To analyze the clinical efficacy and technical key points of genioplasty for the deformities of the chin.Methods 153 patients with chin deformities were treated with the genioplasty,and the chin was moved in any direction,including sagittally,vertically and transversely;the key points of this procedure were summarized.Results There was no severe complication such as infection or nonunion observed.15 patients had ecchymosis and faded in 2 weeks;33 patients had hypaesthesia and recovered in 12 weeks.With the 12-24 months follow-up,all the patients healed well with satisfactory aesthetic results.Conclusions The genioplasty is a reliable and efficient method for the deformities of the chin,and it can significantly improve the appearance of the chin.

Objective To evaluate the effect of three-point rigid internal fixation technique in reduction malarplasty for prominent malar complex.Methods From January of 2014 to January of 2017,45 patients with prominent malar complex were treated with double L shape osteotomy combined bony Z plasty and three-point rigid internal fixation for prominent malar complex.The preoperative and postoperative photographs were taken to monitor the contour improvement,the adverse effects were recorded,and 3D CT was used to assess the bone union situation at 6 months after operation.Results All the wounds got primary intention healing and no severe complication occured in perioperative period.3D CT showed good bone recovery 6 months after operation.Postoperative appearance of all cases showed that the width of middle face was efficiently reduced.All patients expressed high levels of satisfaction.Conclusions Reduction malarplasty with three-point rigid internal fixation for prominent malar complex is an effective and safe method for the treatment of prominent malar complex.

Objective To compare the efficacy between autologous fat and hyaluronic acid in filling nasolabial grooves.Methods Sixty patients who wanted improvement of nasolabial grooves were involved in the study.They were randomly and equally classified into two groups:autologous fat injection group and hyaluronic acid injection group.Photographs were taken before,half a year,and one year after injection.The nasolabial grooves were also graded before,half a year,and one year after injection.The grade improvement was obtained after postoperative grade minus preoperative grade.If the grade improvement was more than 1 grade,the treatment was regarded as effective to evaluate the outcome between the two methods.Results The results of the two groups were tested by SPSS 13.0 software.The effects of the two methods were not significantly different after half a year of filling (P＞0.05).The difference was significant one year after filling (P＜0.05).In autologous fat injection,the patients had a long and magnificant swelling and redness around the nasolabial grooves;on the contrary,the patients who underwent hyaluronic acid had slight and short-time local reaction like swelling and redness.No other serious complications were found in both the groups.Conclusions The effects of the autologous fat and the hyaluronic acid are equal after half a year of filling.The autologous fat has a longer effect in one year.Both methods are safe and effective.Surgeons can select the method accordingly.

OBJECTIVETo study the biomechanical properties of the new bone generated by mandibular distraction osteogenesis (DO).

METHODSA total of 11 healthy adult goats were randomly divided into 2 groups, the experimental group (n=9) and the control group (n=2). For the goats in the experimental group, the bilateral mandibles were gradually lengthened for 10 mm with distraction appliances. Three goats were sacrificed respectively at 2, 4 and 8 weeks after completion of distraction. Compressive, three-point bending and shearing tests were conducted on the standard regenerated bone samples and the whole unilateral mandibular specimens. For the goats in the cont rol group, no operation was made and the whole unilateral mandible was taken as the test specimen.

RESULTSThe compressive strength and bending stiffness of the new bone reached the normal level at 4 and 8 weeks after completion of distraction, respectively. But the shearing strength remained significantly weaker than that of the controls at 8 weeks after distraction.

CONCLUSIONSThe distraction appliance can be removed and the lengthened mandible should be exposed to adaptive functional exercise at 8 weeks after completion of distraction.
