ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
Objective To evaluate the effectiveness of using the anterolateral thigh flap and splitthickness skin grafting to repair large skin defect secondary to the excision of massive penoscrotal Paget's disease.Methods Clinical data of 6 patients with massive penoscrotal Paget's disease were retrospectively reviewed.The patients were admitted to our institute from Feb.2005 to Oct.2010 with mean age of 64 (55-68) years.No other neoplasm and enlarged inguinal lymph node were detected on physical examination,ultrasonography and CT scan.All cases underwent wide local excision of skin lesion which was taken 2 cm beyond the boundary under epidural anesthesia.An anterolateral thigh flap was used to reconstruct the scrotum,and the skin defect of penis was repaired by split-thickness skin grafting.Results Operation was uneventful for the 6 patients,with mean skin defect of 185 (150-210) cm2.The mean operative duration was 270 (210-300) min,and the mean blood loss was 75 (35-150) ml.Negative surgical margins were confirmed on postoperative pathology.Five patients recovered smoothly with satisfying cosmetic appearance,and one patient demonstrated partial necrosis of the flap which was repaired on secondary surgery.The mean follow-up was 37 (10-60) months,and no relapse was found.Conclusions It is an effective method to use anterolateral thigh flap and split-thickness skin grafting to repair large skin defect secondary to excision of massive penoscrotal Paget's disease.
ABSTRACT
Objective To investigate the blood supply of the expanded skin flap from medial up-per arm and its application in the reparation of cervical scar contracture due to sear resection. Methods The operation was carried out for three steps: (1) The expander was implanted under the superficial fascia. (2) The skin flap from medial upper arm was created with superior ulnar collateral artery as blood supply and attributive branches of basilica and axillary veins as blood collection. (3) After thes car contracture was released, the defect was covered with medial upper arm flap with maximal area of 25 cm×15 cm. Results Ten patients in all with cervical scar contracture were treated with the skin flap. All the skin flaps survived at last with nearly normal skin color, texture and contour. And the scar in donor sites seemed to be neglectable. Conclusions Reparation of cervical scar contracture with medial upper arm skin flap after expanding could be recommended. But 3 months long time and fixation of upper limb and head might be disadvantages.
