ABSTRACT
Objective:To explore an optimal surgical approach for different types of labia minora hypertrophy and to design a better personalized surgical treatment plan for patients.Methods:From October 2017 to October 2020, 71 patients with labia minora hypertrophy were treated in the plastic surgery department of Sichuan Provincial People＇s Hospital, aged 18-38 years, with an average of 26 years. According to the type and degree of hypertrophy, the appropriate surgical method was selected. The wound healing and complications were observed after operation, and the shape of labia minora was followed up.Results:Among the 71 patients, 1 patient had postoperative hematoma and no flap necrosis after active treatment. 1 patient had poor healing of distal labia minora incision and improved after dressing change. The other patients had good blood supply of labia minora, no necrosis, no postoperative infection, hematoma and other complications. The patients were followed up for 1-6 months. The appearance of labia minora was natural, bilateral symmetry, and the incision scar was hidden. The improvement was significant compared with that before operation. The patients were satisfied with the shape and function.Conclusions:According to the degree of hypertrophy of the labia minora, the specific shape and the psychological expectation of patients, we can choose the appropriate operation method, which can achieve the aesthetic standard of symmetry and beautiful shape of the labia minora, and meet the normal physiological function and aesthetic requirements of patients.
ABSTRACT
Objective:To investigate the clinical application and effect of orbicularis oculi muscle shaping in lower blepharoplasty.Methods:A retrospective analysis was performed on the clinical data of 32 cases of flabby blepharoplasty patients admitted to the Orthopedic Surgery Clinic of Sichuan people＇s Hospital from October 2018 to September 2019. At the same time of transcutaneous blepharoplasty, 32 patients were treated with orbicularis oculi muscle shaping to remove the relaxed orbicularis oculi muscle, to reconstruct the annular strength and shape of the orbicularis oculi muscle, to strengthen the supporting structure of the lower eyelid, to reset the relationship between the external canthus orbicularis muscle and the skin, and then to reconstruct the soft tissue filling degree of the lower eyelid margin. The safety, efficacy and stability of the operation were evaluated by Barton grading, postoperative complications and scoring before and after operation and satisfactory analysis based on patients＇ satisfaction scale after operation.Results:All the patients were free of postoperative infection and healed at stage I. There were 2 cases of ecchymosis, 3 cases of ocular foreign body sensation, and no cases of infection, lower eyelid retraction, lower eyelid ectropion, or retrobulbous hematoma. The mean Barton score of all patients before surgery was 1.88±0.49, and the mean Barton score after surgery was 0.53±0.51. The t-test showed that the difference was statistically significant ( t=15.75, P<0.05), and the postoperative lacrimal groove deformity was improved. According to the score of satisfaction scale, 7 people were basically satisfied (21.88%) and 25 people were very satisfied (78.12%). Conclusions:Forming in the orbicularis oculi muscle relaxation eyelid bag type of prosthesis, in addition to the part of the orbicularis oculi muscle relaxation, deformation, and widely shed canthus outside skin and orbicularis connection, make the next eyelid edge to reproduce the full shape, obviously the bulging under the eyelid relaxation, the shape of the degree of repair, lateral canthus wrinkles tail department have also improven, restoring the full eyelid platform. The operation has strong pertinence, simple procedures, less complications and better long-term effect.
ABSTRACT
Objective:To explore the effect of the principle of tissue gradient difference in repairing the over wide eyelid fold after double eyelid operation by incision.Methods:From July 2019 to July 2020, we applied the principle of tissue gradient difference to 30 cases (a total of 60 eyes; age ranging 20-35 years with mean 30) of female patients with excessively wide eyelids after incision double eyelid surgery needing a repair. All cases were from the Plastic Surgery Department of Sichuan Provincial People＇s Hospital. The difference in tissue gradient was manifested as the difference in thickness, texture and tension of soft tissues such as the skin above and below the double eyelid line and the orbicularis oculi muscle.Results:Satisfactory evaluation results showed in a total of 30 patients with 60 eyes, 95.0% ( n=57) were satisfied, and 5.0% ( n=3) were dissatisfied. Two of the patients received the second repair due to the inconsistency of the double eyelid width after correction. One patient obtained satisfactory double eyelid morphology after the second repair, and the other patient obtained satisfactory double eyelid morphology after the third repair. Evaluation results of double eyelid morphology showed that it obeyed a normal distribution by analyzing the difference between preoperative and postoperative double eyelid morphology scores. The results of paired t test showed that the double eyelid morphology was significantly improved 6 months after operation compared with preoperative, and the difference was statistically significant ( t=15.86, P<0.01). Conclusions:The principle of tissue gradient difference guides the repair of double eyelid width that is simple and easy, the effect is good, and it is worth applying.
ABSTRACT
Objective: To explore the feasibility and effectiveness of using auricular cartilage multi-point suspension fixed on deep craniofacial fascia in correcting mild to moderate cupped ear malformation. Methods: Between January 2014 and March 2016, 22 patients (12 males and 10 females) with mild to moderate cupped ear malformation were admitted, aged from 6 to 28 years, with an average age of 15 years. Sixteen cases were unilateral and 6 cases were bilateral. According to Tanzer classification, there were 18 sides of type Ⅰ and 10 sides of type Ⅱ. The otocranial groove incision was selected to expose and release the posterior auricular muscles and ligaments. The abnormal structure of auricle subunits was remolded. The auricle cartilage was suspended and fixed on the deep craniofacial fascia with non absorbable line to remodel the shape and position of auricle. Results: The incision healed by first intention, without hematoma, infection, and skin necrosis. All the patients were followed up 3-48 months, with an average of 12 months. In addition to 1 case of slippage of the fixed line knot, the effect was good after being suspended and fixed again, the auricles of the other patients were not drooping and tilted forward, the shape of the outer ear was good, the ear boat was obvious, the shape of the upper and lower feet of the ear wheel and the pair of ears was natural, the bilateral symmetry was good, and the patients and their families were satisfied. Conclusion: Auricular cartilage multi-point suspension fixed on deep craniofacial fascia is effective in the treatment of mild to moderate cupped ear malformation.
ABSTRACT
Objective@#To study the effect of individualized treatment of prominent ears using mattress suture combined tubed cartilage method.@*Methods@#A total of 21 patients (28 ears) with prominent ear deformity were retrospectively analyzed from January 2013 to December 2015. Horizontal mattress suture and tubed cartilage were used to correct the deformed ears. The patients were followed up for 6 months to 1 year (mean: 9 months).@*Results@#Hematoma occurred in 3 cases after operation, but the wounds were healed after removal of hematoma. No infection, flap necrosis, cartilage absorption or deformation, or other complications occurred. 28 ears were corrected. The shape of the antihelix was smooth and the auriculocephalic angle and scapha-conchal angle were significantly reduced, compared with preoperative. No obvious scar hypertrophy was left on incision.@*Conclusions@#The method of horizontal mattress suture combined with tubed cartilage is simple to use for prominent ear, result in satisfactory and stable outcomes.
ABSTRACT
According to current assembly situation of infant incubator in company A, basic industrial engineering means such as time study was used to analyze the actual products assembly production and an assembly line was designed. The assembly line was modeled and simulated with software Flexsim. The problem of the assembly line was found by comparing simulation result and actual data, then through optimization to obtain high efficiency assembly line.
