Late Intracapsular Seroma in Subfascial Buttock Augmentation: A Case Report

Late intracapsular seroma and hematoma have been described frequently as a complication of breast augmentation surgery. However, there are few reports of late intracapsular seroma in buttock augmentation. Textured and polyurethane implants have been used for subfascial enlargement of the buttocks. In this article, the authors report a large late intracapsular bilateral seroma caused by a retrofascial polyurethane-covered implant used for buttock augmentation: 1,200 ml on one side and 300 ml on the other. This patient’s intracapsular seroma was of sudden onset 2 years and 6 months after surgery, and apparently had no relation to any trauma, use of medication, or physical exercise. Local tissues, including the gluteal fascia, were distended such that the implant was replaced inside the muscle and there was no relapse of the seroma. Late intracapsular hematomas or seromas from implants for buttock and breast augmentation may have the same etiology, and textured implants seem to be involved. All the reports on the matter are associated with textured implants. Any late seroma or hematoma caused by a smooth implant is related to an additional factor that may be considered as the etiologic agent. Further studies aimed at a large-scale assessment of the cause and actual incidence of late seromas and hematomas from textured implants are required.     

An Unusual Complication of a Medpor Implant in Nasal Reconstruction: A Case Report

There are few implant materials which have been successfully used for nasal reconstruction. Of these, the medpor implant is the most accepted alloplastic material for reconstruction of the nasal framework. Here, an unusual complication of a medpor implant in nasal reconstruction is presented. A 24-year-old medical student suffering from a saddle nose deformity after a primary rhino plasty was admitted to our department. The medpor nasal implant was used to restore the nasal dorsum. The surgical result was appreciated by the patient. No problem was encountered during two years after surgery. Recently, the patient suffered from an asymmetry of the nasal dorsum. The physical examination revealed a step on the nasal dorsum with caudal mobility of the implant. The nasal implant was suspected to be broken. Multislice CT scan and ultrasonographic imaging of the implant were obtained. The radiologic evaluation of the region confirmed the fracture of the medpor nasal implant. Nasal reconstruction with a medpor implant is a good choice with low complication rates. This is the first case in the literature reporting a broken medpor nasal implant. Moreover, in this study a new method is described for imaging the medpor implant material.     

Mycobacterium chelonae Infection Following Silicone Arthroplasty of the Metacarpophalngeal Joints: A Case Report

We present a case of infection caused by an uncommon pathogen, Mycobacterium chelonae, in a patient that underwent Swanson silicone arthroplasty of the metacarpophalangeal joints for rheumathoid arthritis. This is the first report of an infection caused by nontuberculous Mycobacteria in flexible silicone implants in the hand. The patient was successfully treated with implant removal, debridement, and antimicrobials tailored to the results of in vitro susceptibility testing.     

Autologous Fat Transplantation and Delayed Silicone Implant Insertion in a Case of Mycobacterium avium Breast Infection

Background  

Infection after breast augmentation is uncommon, occurring in 1–3% of cases. They are typically caused by bacterial skin flora, specifically Staphylococcus aureus and the coagulase-negative staphylococci. There have been infrequent reports of breast implant infection caused by the atypical mycobacteria.     

Late Hematoma After Aesthetic Breast Augmentation with Textured Silicone Prosthesis: A Case Report

Late hematoma is an extremely rare complication after augmentation mammaplasty with silicone prostheses. The authors present a case of late hematoma after breast augmentation with textured gel-filled silicone prostheses, which appeared after intense physical effort 1 year after the implantation of the prosthesis. The hematoma was drained in three subsequent ultrasound-guided percutaneous needle aspirations, with no need for removal of the implant. In a 9-month follow-up period, the patient had no other problems with the implants.     

Transverse Upper Gracilis Flap with Implant In Postmastectomy Breast Reconstruction: a Case Report

Autologous flaps can be used in combination with prosthesis in postmastectomy breast reconstruction. The deep inferior epigastric perforator (DIEP) flap is considered the preferred choice among autologous tissue transfer techniques. However, in patients with a peculiar figure (moderately large breasts and large thighs with flat stomach), who cannot use their abdominal tissue, the transverse upper gracilis (TUG) flap with implant is investigated as a further option for breast reconstruction. This report presents a patient who underwent the TUG flap plus implant reconstruction. A bilateral skin‐sparing mastectomy was performed removing 340 g for each breast. The volume of the TUG flaps was 225 g (left) and 250 g (right). Preoperative volumes were restored by placing under the TUG muscle a round textured implant. No complications occurred during the postoperative period both in the recipient and donor site and the outcomes of the procedure were good. In cases where the use of the DIEP flap is not possible because of past laparotomies or inadequate abdominal volume, the TUG flap plus implant may be considered as a valid alternative. © 2013 Wiley Periodicals, Inc.

Fibromatosis Associated with Silicone Breast Implant: Ultrasonography and MR Imaging Findings

Desmoid type fibromatosis is an uncommon benign disease entity of which its etiology is currently unknown. It constitutes 0.3% of all solid neoplasms, but it is rarely seen in the breast and even more scarcely reported to develop in association with breast implant. We present ultrasonography and magnetic resonance imaging findings of a 29‐year‐old female patient with fibromatosis after breast implant surgery. Knowledge of imaging findings of breast fibromatosis associated with implant will be helpful for accurate diagnosis and appropriate management.     

Effect of Fixation, Soft-Tissues, and Scan Projection on Bone Mineral Measurements with Dual Energy X-ray Absorptiometry (DXA)

The objective of this study was to determine the effect of fixation, soft tissues, and scan projection on bone mineral measurements with dual energy X-ray absorptiometry (DXA). In seven fresh cadavers, DXA scans were obtained within 48 hours of death and after 10 months of fixation with 5% formalin/95% ethanol. The measurements showed a high linear relationship (r2 > 0.97; SEE% < 10%), with no significant deviation after fixation (except for total body BMD: -3.1%). In 14 specimens, the precision of femoral and spinal analyses was determined under in situ and ex situ conditions. There was no significant difference between ex situ and in situ reproducibility, the coefficient of variation being < 3% for the BMC and < 2% for the BMD (except at the greater trochanter). The effect of the soft tissues and scan projection was assessed in 83 cadavers aged 80.4 +/- 10.3 years. The soft tissues had only a small effect on analyses of the total femur (r2 > 0.90; SEE% < 9%), but led to more substantial deviations in regional femoral analyses and in the spine (r2 = 0.78-0.90; SEE% = 8-22%). Comparing lateral with anterior-posterior (AP) spinal scans, the vertebral bodies were found to occupy 40.2 +/- 7.2% of the BMC, and 62.0 +/- 11.2% of the BMD, the ranges being 26-58%, and 38-91%, respectively. There were large deviations from linearity between in situ AP and ex situ lateral spinal scans with r2 values of 0.63 and 0.73 for BMD and BMC (SEE% = 52% and 27% relative to the vertebral body), respectively.     

Late Spontaneous Extrusion of a Texturized Silicone Gel Mammary Implant

A case report of late spontaneous extrusion of a 250-cm³, round, texturized silicone gel mammary implant, 14 months after implantation, is presented. The irregular surface of the implant, the location of the implant pocket, and the absence of the fibrous capsule were responsible for alterations in the skin thickness. In addition, the pressure exerted by the implant against the skin provides for stasis with venous trombosis at the inferior portion of the breast. The continuous manipulation of the breast over a thin skin with vascular alterations led to the skin perforation with implant extrusion.     

Quantification of Scan Analysis Errors in GE Lunar DXA Visceral Adiposity in Adults

Utilization of dual-energy X-ray absorptiometry is increasing in clinical settings and the fitness industry as a viable tool to assess total and regional body composition, including visceral adiposity. Previous research using small samples (<50) has described several pitfalls in patient positioning, scan acquisition, and/or analysis that alter regional body composition values. Our aim was to quantify the largest probable error in measures of total, android, gynoid, and visceral fat caused by incorrect placement of the head cut-line, in a large sample of adults. Total body images (N = 436) from 196 women and 67 men (20–85 years) scanned on a GE Lunar Prodigy densitometer were analyzed using enCORE software in 2 ways: (1) placing the head cut-line just beneath the bony protuberance of the chin according to manufacturer recommendation (correct method); (2) placing the head cut-line at the lowest point below the chin and just above the soft tissue at the shoulders (incorrect method). All other cut-lines were fixed. Mean differences in adiposity were examined using Lin's concordance correlation coefficient; equality of means and variances were evaluated using Bradley-Blackwood F-tests. The limits of agreement were displayed as Bland-Altman plots and calculated as the mean difference ±1.96 times the standard deviation of the difference. Correlation coefficients for paired comparisons of adiposity for correct vs incorrect cut-line placement ranged from 0.983–0.999 for all variables (all p < 0.001). Significant mean differences were 172 ± 130, 201 ± 168, 65 ± 122, and ?143 ± 336 g for android, gynoid, visceral, and total fat mass, respectively (all p < 0.0001). These differences exceeded our site's least significant change in 66%, 37%, 29%, and 4% of participant scans for android, gynoid, visceral, and total fat mass, respectively. Our findings underscore the importance of careful review of the manufacturer's auto analysis and consistency in conducting serial scans to ensure accurate and precise measures of regional body fat.     

International Breast Implant Registry: A User Report

The International Breast Implant Registry (IBIR) was founded in 2002 under the auspices of the International Plastic, Reconstructive, and Aesthetic Surgery Foundation (IPRAF), the International Confederation for Plastic, Reconstructive, and Aesthetic Surgery (IPRAS), and the European and International Committee for Quality Assurance, Medical Technologies, and Devices in Plastic (EQUAM) on the basis of continuous discussion about the safety and compatibility of different breast implants. The IBIR aims to integrate and replace the already existing national breast implant registries. It also is assumed that the European Parliament, the Food and Drug Administration, and international organizations of plastic and aesthetic surgeons will postulate obligatory international breast implant registration. Currently, IBIR is in a pilot phase with the goal of understanding data collection issues and concerns in various countries whereby the data entered to date will be completely available in the final version. A well-established global registry represents an important tool of quality assurance. By publishing their experiences in applying the registry, the authors aim to encourage more plastic and aesthetic surgeons to submit their cases to the registry and thus enhance its value as a successful and powerful device.     

Osteoarthritis of the Trapezio-Metacarpal Joint: Results of Treatment with a Silicone Cap Implant

The results of surgical treatment for arthritis of the first carpometacarpal joint using Kessler's silicone implant were examined in a group of 23 patients. The mean follow-up period was 24 months. Pain relief was obtained in 18 patients (78 per cent), functional improvement in daily activities in 16 patients, and power of pinch and power of grasp were improved in 10 out of 13 patients. Limitation of abduction complicated surgery in 6 patients. A high incidence of subluxation was found without correlation to the subjective results. Most of our patients were satisfied with the functional end results.
