Values of mammography, ultrasound and magnetic resonance imaging in diagnosing breast cancer with silicone implants / 中华医学美学美容杂志

Objective:To investigate the diagnostic value of X-ray mammography, ultrasound and MRI in breast cancer with silicone implants.Methods:The clinical and imaging data of 20 patients with breast cancer in women with silicone implants in the First Affiliated Hospital of Zhengzhou University from March 2014 to October 2021 were analyzed retrospectively. The mammography, ultrasound and MRI findings were analyzed, and the differences in detection rate, diagnostic accuracy and omission diagnostic rate of breast cancer in women with implants were compared among the three imaging methods.Results:Compared with mammography, both ultrasound and MRI were able to display the prosthesis and breast lesions completely. There were significant differences in detection rate, diagnostic accuracy and omission diagnostic rate among mammography, ultrasound and MRI. And the detection rate and diagnostic accuracy of MRI in breast cancer in women with implants were higher than those of mammography, and the omission diagnostic rate was lower.Conclusions:Ultrasound and MRI are superior to mammography in evaluating breast cancer after silicone prosthesis implantation, and MRI has more advantages in guiding clinical diagnosis and treatment.

Efficacy of autologous costal cartilage combined with silicone prosthesis for repair of injection rhinoplasty / 中华医学美学美容杂志

Objective:To investigate the repair effect of autologous costal cartilage combined with silicone prosthesis on injection rhinoplasty.Methods:From July 2016 to July 2019, 28 patients who were dissatisfied with the appearance of injectable rhinoplasty and required surgical repair were treated in our hospital. Among them, 26 patients were injected with hyaluronic acid as filler, and 2 patients were unknown filler. On the basis of thoroughly cleaning the filler and releasing the adhesive tissue, the method of autogenous costal cartilage combined with silicone prosthesis was adopted: the costal cartilage was taken to support the nasal tip, and the silicone prosthesis was used to fill the nasal dorsum. The incidence of complications was observed postoperatively, and the score of each patient before and 6 months after operation was evaluated by ROE questionnaire.Results:No postoperative complications such as skin infection and necrosis, prosthesis deformation and displacement, and pneumothorax were observed in all the patients, and the incision healing was smooth. All patients were followed up for 6-18 months. Among the 6 questions on the preoperative and postoperative ROE questionnaire, except for question 2, the difference between the the two was statistically significant ( t=7.58, P<0.05). Conclusions:The use of autologous costal cartilage combined with silicone prosthesis can effectively repair injection-type rhinoplasty, which can not only achieve satisfactory postoperative results, but also reduce surgical complications. It is easy to operate and worthy of choice in clinical practice.

Diferente das técnicas já descritas, a prótese é implantada na aponeurose do músculo peitoral, proporcionando melhores resultados estéticos e menos complicações no período pós-operatório. Objetivos: O presente estudo tem como finalidade descrever o uso do implante mamário no plano subfascial, além de analisar os índices de complicações de pacientes submetidos a este procedimento. Métodos: Estudo retrospectivo através da análise de prontuário eletrônico de 233 pacientes que realizaram mamoplastia de aumento com descolamento subfascial. Foram excluídas as pacientes que realizaram outras técnicas de implantação de próteses, mastopexia e que utilizaram tamanhos diferentes de próteses. Resultados: A maioria das pacientes optou pela incisão realizada no sulco inframamário, o tamanho das próteses sofreu aumento ao longo do período estudado e apenas uma complicação foi relatada no pós-operatório. Conclusão: A técnica subfascial vem sendo cada vez mais utilizada pelos cirurgiões plásticos por apresentar resultados estéticos satisfatórios e baixos índices de complicações, como demostrado no estudo, tornando-se uma opção diferenciada para pacientes que realizarão a mamoplastia de aumento.

ABSTRACT Introduction: The implantation technique of subfascial silicone prostheses described by Graf in 2003 has advantages over submuscular and subglandular techniques. Unlike the techniques already described, the prosthesis is implanted in the aponeurosis of the pectoral muscle, providing better aesthetic results and fewer complications in the postoperative period. Objectives: The present study aims to describe the use of breast implants in the subfascial plane and analyze the rates of complications of patients undergoing this procedure. Methods: A retrospective study by analyzing electronic medical records of 233 patients who underwent augmentation mammoplasty with subfascial detachment. Patients who underwent other implantation techniques of prostheses, mastopexy and who used different sizes of prostheses were excluded. Results: Most patients opted for the incision performed in the inframammary groove; the size of the prostheses increased over the period studied, and only one complication was reported postoperatively. Conclusion: Plastic surgeons have increasingly used the subfascial technique because it presents satisfactory aesthetic results and low rates of complications, as shown in the study, becoming a differentiated option for patients who will perform augmentation mammoplasty.

Prosthetic Rehabilitation Technique with an Economical Customized Orbital Prosthesis

@#Post-surgical orbital defects pose a severe effect on patient, psychologically and physically, especially in the eventual return to the society and daily routine. In cases where reconstructive surgery is not possible, prosthetic rehabilitation is crucial in addressing this issue. Implant-supported orbital prosthesis provides superior retention, however, it is not economically acceptable for some cases. Various modes of retention are available to cater to each patient’s diagnosis, treatment need and economical status. This article describes the procedures in the construction of a customized silicone orbital prosthesis using adhesive and spectacles for retention. This technique is cost-effective and simple while providing comfort and satisfaction for the patient.

Rehabilitation of orbital defect with silicone orbital prosthesis retained by dental implants.

Orbital defects can result from cancer, birth anomalies, or trauma leading to an onslaught of problems in the function and psyche of the patient. These defects are restored by surgical reconstruction and followed by placement of orbital prosthesis for cosmetic makeup. The use of dental implants in retaining orbital prosthesis improves patient acceptance of the prosthesis owing to better retention and stability than conventional adhesive retained prosthesis. This case report describes a custom‑made magnetic retentive assembly anchored by a dental implant which offers the orbital prosthesis the simplicity of self‑alignment and ease of use.

Immediate Implant Reconstruction using Silicone Prosthesis in Breast Cancer Patients after Skin Sparing Mastectomy

PURPOSE: Since skin sparing mastectomy removes the mammary gland and the nipple-areolar complex preserving all mammary skin, it makes the widespread use of implants in immediate reconstruction. This article reports our experience in immediate breast reconstruction after skin sparing mastectomy by using the silicone implants in patients especially who have small to moderate sized and minimal ptotic breast. METHODS: From September of 2007 to July of 2009, we performed breast reconstruction for 44 breasts of 40 women with silicone implant after mastectomy. Tumors were divided into 5 malignant types (21 IDC, 18 DCIS, 2 ILC, 2 phylloides tumor, 1 mucinous carcinoma). The implant is placed in a submuscular pocket or in a submuscular-subfascial pocket depending upon the condition of the muscles and skin flaps after mastectomy. RESULTS: The mean age was 47 years and the average follow-up period was 11 months. Cosmetic outcome was assessed by evaluation of photographs and assessment of breast volume and shape, breast symmetry, and overall outcome. About 80% of each of these parameters was scored as good or excellent. Breast complication was developed in a total of 6 cases including 2 capsular contracture, 2 partial skin necrosis due to blue dye injection and 2 implant infection. CONCLUSION: The use of definitive implants in a skin sparing mastectomy is a one-stage immediate breast reconstruction with low morbidity and acceptable result. This method is considered reliable with favorable aesthetic result.

PURPOSE: To evaluate the clinical outcome of silicone radial head prosthesis for treatment of comminuted radial head fractures. MATERIALS AND METHODS: Seven patients who had taken a radial head replacement with a silicone prosthesis from November 2001 to April 2004 were enrolled in the study. Mean age was 49.1 years old when they sustained a fracture of the radial head or neck. There were two Mason type III fractures and five Mason type IV fractures. Associtated injuries were a variant of Monteggia fracture, Essex-Lopresti injuries and a capitellum fracture. Mean follow-up was 20.3 months. The clinical outcome was analized by Mayo Elbow Performance Index. RESULTS: Overall outcome was that two cases were excellent, four cases were good and one case was fair. There were complications which included limitation of motion, radioulnar synostosis and proximal migration of radius. CONCLUSION: The silicone radial head prosthesis was found to be recommendable treatment option for patients with Mason type III and IV radial head fractures which were difficult to be reconstructed.

A Case of Thigh Augmentation with Silicone Prosthesis in a Poliomyelitis Patient

Until now, aesthetic concerns have been focused on the face, especially on the eyes, nose and facial contour. But recently, many people have interest in the aesthetics of the trunk and extremities. There is an increasing demands for the correction or improvement of the trunk and extremity contour, especially in cases of poliomyelitis and posttraumatic deformity. Authors did the thigh augmentation with silicone prosthesis in a poliomyelitis patient. Subfascial pocket was made and prefabricated silicone implants were placed in the pocket. Circumferential differences between affected thigh and unaffected thigh were reduced from 11 cm(15 cm above knee), 9 cm(25 cm above knee) to 2.5 cm, 3 cm. No definitive complication was present. So, authors conclude that this technique is useful to obtain the good results in the aesthetic correction of asymmetric thigh.
