Application of mobile device-based video teaching in plastic surgery education / 中华医学教育探索杂志

Objective:To assess the feasibility and effects of the mobile device-based video teaching in plastic surgery education.Methods:In the study, 22 participants were assigned into two groups according to their standardized training area. The intervention group ( n=11) which was outside Beijing had an unlimited access to video-based education; the control group ( n=11) which was in Beijing received traditional teaching. After the end of the first semester of teaching, the two groups of students were tested on theory and clinical operational theory, and the evaluation results were compared. SPSS 18.0 software was applied for t test and chi-square test. Results:After the first semester, the effect of teaching method was evaluated by the scores of written examination and clinical examination. The average scores of the written test in the intervention group were (38.82±3.22) points, while that in the control group were (38.36±2.98) points, without significant differences between the two groups ( P=0.74); the average scores of the clinical examination theory test in the intervention group and the control group were (46.36±3.44) points and (41.00±5.24) points, respectively, with significant differences between the two groups ( P=0.01). In term of total scores, the average scores of the intervention group were (85.18±4.83) points, and those of the control group were (79.36±5.52) points, with statistical differences between the two groups ( P=0.016). Conclusion:Mobile device-based video teaching in plastic surgery education can not only improve students' performance but also facilitate their clinic skills, which is worth popularizing.

A new classification of labia minora hypertrophy and surgical methods / 中华整形外科杂志

Objective@#To introduce a method to classify the labia minora hypertrophy and to investigate its significance to the selection of surgical method.@*Methods@#From August 2014 to April 2018, 1 058 patients with labia minora hypertrophy were treated in the Plastic Surgery Hospital. According to the hyperplastic degree of the labia minora and praeputium clitoridis, the labia minora hypertrophy was classified to three types, namely simple clitoridis hypertrophy, simple labia minora hypertrophy and mixed type. For patients with simple labia minora hypertrophy, the methods of margin resection, or wedge resection or combination were applied. For patients with simple clitoridis hypertrophy, the reduction of clitoris hood could be performed. For mixed type, firstly the relationship of clitoris hood and labia minor should be recognized, then the appropriate surgical method should be taken.@*Results@#The age of the patients was 18 to 46 years (mean age was 25 years). 83 cases (7.8%) were simple labia minora hypertrophy. 25 cases (2.4%)were simple clitoridis hypertrophy. And 950 cases (89.8%) were mixed type. All the patients received appropriate surgical method to repair the malformation. All the surgeries were successfully performed and the cosmetic results were satisfying.@*Conclusions@#As the homologous tissues, whether praeputium clitoridis hypertrophy or labia minora hypertrophy could result poor appearance of female vulva. The concept of holism should be kept in mind when repair surgeries are performed. The labia minora hypertrophy was classified to three types and appreciate surgical methods were applied to repair the hypertrophy. The cosmetic result was satisfying.

A preliminary study on measurements of 512 normal female genital appearance of Han and Uygur nationality in Xinjiang / 中华整形外科杂志

Objective@#To collect preliminary data of normal Chinese female genital appearance, to compare the parameters of Han and Uygur nationality, and to present the preliminary data for normal female external genitalia database.@*Methods@#This study design recruited healthy females referred to the out-patient clinic for physical examination from October 2014 to March 2015 in Xinjiang Petroleum Geological Survey Department Staff Hospital. The recruitment was based on rigid inclusion and exclusion criteria. Demographic data consists of nationality, age, height, weight, marital status, gravidity, parity, vaginal delivery, and intercourse frequency. Anthropometric measurements were taken in 234 females of Han group whereas 278 females of Uygur group. For each individual 16 parameters were measured. The external genitalia appearance in Han and Uygur nationality was compared. The significance of variations in age, height, weight, BMI, gravidity, parity, vaginal delivery and intercourse frequency were analyzed.@*Results@#Primary measurements of Han and Uygur nationality are presented as mean (95% confidence interval). There are many differences in female genital appearance between Han and Uygur nationality. Several parameters were statistically associated with age, BMI, gravidity, parity, vaginal delivery and intercourse frequency. The females with complete labial asymmetry account for 5.6%(13/234) and 5.8%(16/278) in Han and Uygur normal adults, respectively.@*Conclusions@#This study presented the external genitalia measurements of normal Chinese female adults in Xinjiang, thus providing the preliminary data for normal female external genitalia database. Females of Han and Uygur nationality have multiple differences in external genitalia appearances. The parameters are associated with age, BMI, gravidity, parity, vaginal delivery, and intercourse frequency. The labial asymmetry is a universal phenomenon.

The effects of modified adhesion retention on the surrounding tissues of dental implant / 实用口腔医学杂志

Objective:To investigate effects of the modified adhesion retention on the surrounding tissues of dental implant.Methods:182 patients with tooth defects were randomly divided into 2 groups,The patients in control group (n =89) received the traditional retention,in the test group(n =93) received modified adhesion retention.The bone loss at the near and far edges of the implant,alveolar bone height and thickness,the pictorial view of pink esthetic score variables(PES),the modified plaque index(mPLI),the modified sulcus bleeding index (mSBI) and the satisfaction were recorded and compared 1 year after treatment.Results:Compared with control group,the test group showed less bone loss(P＜0.05),more alveolar bone height and thickness(P＜0.05).The satisfaction of the comfort,chewing and language function,retention,esthetics,PES,mPLI and mSBI improved to varying degrees(P＜0.05).Conclusion:The modified adhesion retention is more effective than the traditional retention in stabilizing the bone support of implant and reduce bacterial infection.

Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermal matrix / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.</p><p><b>METHODS</b>We retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.</p><p><b>RESULTS</b>The time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.</p><p><b>CONCLUSIONS</b>Vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.</p>
