OBJECTIVETo explore the therapeutic effect of the temporal rotation flap combined with cartilage plasty for cryptotia correction.
METHODSFrom January 2009 to June 2012, 8 cases with cryptotia (10 ears) were treated. After complete dissection of the cartilage adhesion, the cartilage was reshaped by suture to restore its appearance. Then the temporal triangular rotation flap was transferred to cover the wound.
RESULTSNo hematoma, infection or flap necrosis happened. The follow-up period ranged from 3 months to 1 year, with an average of (6.88 +/- 2.85) months. The ear appearance kept stable with no recurrence and inconspicuous scar. Satisfactory result was achieved.
CONCLUSIONTemporal rotation flap combined with cartilage plasty is a good option for correction of mild or moderate cryptotia.

OBJECTIVETo explore the reasonable therapeutic strategy for different types of epicanthus.
METHODSPatients with epicanthus were classificated according to the shape, extent and inner canthal distance and treated with different methods appropriately. Modified asymmetric Z plasty with two curve method was used in lower eyelid type epicanthus, inner canthus type epicanthus and severe upper eyelid type epicanthus. Moderate upper epicanthus underwent '-' shape method. Mild Upper epicanthus in two conditions which underwent nasal augumentation and double eyelid formation with normal inner canthal distance need no correction surgery. The other mild epicanthus underwent '-' shape method.
RESULTSA total of 66 cases underwent the classification and the appropriate treatment. All wounds healed well. During 3 to 12 months follow-up period, all epicanthus were corrected completely with natural contour and unconspicuous scars. All patients were satisfied with the results.
CONCLUSIONSClassification of epicanthus hosed on the shape, extent and inner canthal distance and correction with appropriate methods is a reasonable therapeutic strategy.

Objective To summarize and explore the clinical effect of auricular reconstruction with autologous costal cartilage grafts and delaying postauricular skin flap.Methods The procedure involved three stages.The first stage was the delay procedure of postauricular skin flap.The second stage was the auricular reconstruction with autologous costal cartilage grafts and delaying postauricular skin flap about 3 weeks after the delay procedure.The third stage involved construction of tragus and conchal cavity and other local correction 6 months or longer after the second stage surgery.The clinical effect,patients' satisfaction and complication were observed.Results This method was used in 28 patients,31 ears of congenital microtia.23 cases completed auricular reconstruction with three stages,the other 8 cases completed only two stages.All auricular reconstruction were successful.The location,size and shape of reconstructive ears were good.The complications were few.The patients or their relatives were basically satisfactory.Conclusions Auricular reconstruction with autologous costal cartilage grafts and delaying postauricular skin flap is a safe and effective method.

Objective To investigate the clinical effect of 595 nm tunable pulsed dye laser (PDL) in treating fresh trauma scars.Methods 85 patients had been selected,of which,117 sites were treated with a 595 nm tunable PDL one time or two times at a fluence of 7-15 J/cm2 and pulse widths of 1.5-3 ms,7 mm spot size.Nursing skill of burn wound was also used on treatment area after laser treatment.Scars were evaluated for melanin,height,vascularity and pliability using the Vancouver Scar Scale (VSS) before treatment and after the last treatment 8weeks.Results Total score of 117 sites decreased from (8.30 ± 2.63) to (2.70 ± 1.25),melanin decreased from (1.60 ± 0.84) to (0.60 ± 0.97),height decreased from (1.30 ± 0.82) to (0.40 ± 0.51),vascularity decreased from (2.40 ± 0.52) to (0.40 ±0.52),pliability decreased from (2.80 ± 1.32) to (1.30 ±0.48),with statistical significance between before treatment and after treatment (P < 0.05).Conclusions 595 nm tunable pulsed dye laser appears to have a beneficial clinical effect on patient's fresh trauma scar.

The prevention and treatment of scars has always been an important task in the field of wound repair.Humans have started treatment for scars long time ago and have created a series of treatments.At the same time,with the development of science and technology,the diagnosis and treatment of scars have made great progress.Through the basic research for new therapeutic targets and innovative of treatment methods,treatment for scar turns more diversified and integrated.As a result,clinicians will suffer many challenges while having more options for scars treatment.Combined with traditional treatment,developing new treatments,and the comprehensive therapy of multiple treatment methods is the mainstream trend of scar treatment.
6.The effect of gauze filtration on the content of adipose stem cells in fat gel
Journal of Chinese Physician 2024;26(3):341-344
Objective:To study the effect of gauze filtration on the content of adipose stem cells in fat gel.Methods:In March 2022, fat samples from 5 patients who underwent abdominal fat aspiration at the Hunan Provincial People′s Hospital were collected, prepared fat ged, the fat gel was filtered 1-5 times with 2 layers of gauze, and the amount of fat gel passing through a 1 ml threaded syringe with a 27 G needle was measured after each filtration. At the same time, the content of fat stem cells in the filtered fat gel was detected by flow cytometry.Results:As the number of filters increases, the amount of fat gel passing through gradually increased. The increasing trend was obvious after the first to fourth filters, and the increasing trend slowed down after the fifth filter. After statistical analysis, the differences between the first filter and the second filter, the second filter and the third filter, and the third filter and the fourth filter were statistically significant ( P<0.05). There was no statistically significant difference between the fourth filter and the fifth filter ( P>0.05). As the number of filters increased, the content of adipose stem cells in the fat gel gradually decreased. The decreasing trend was obvious after the first to third filters, and the decreasing trend slowed down after the fourth filter. After statistical analysis, the differences between the first filter and the second filter, as well as the second filter and the third filter, were statistically significant (all P<0.05). However, there was no statistically significant difference between the third filter and the fourth filter, and the fourth filter and the fifth filter (all P>0.05). Conclusions:The more times gauze is filtered, the better the permeability of fat gel. However, the content of adipose stem cells will significantly decrease in the first three filters. Therefore, the number of times gauze is filtered for fat gel should be minimized as much as possible.
