Long-term results of MISTI gold breast implants: a retrospective study.

MISTI Gold breast implants (Bioplasty, St. Paul, Minn.) filled with polyvinylpyrrolidone-hydrogel were developed as a promising alternative to silicone-filled implants. Some studies have reported on the positive effects of the implant, such as improved radiolucency and biocompatibility of the gel; however, there are also reports that such implants increased in volume and were subject to capsular contracture in the human body, resulting in demands for their removal. The purpose of this retrospective study was to analyze the long-term results of a series of patients with MISTI Gold breast implants. Between 1991 and 1993, the authors inserted 83 MISTI Gold implants in 61 patients with an average age of 46 years (range, 16 to 69). The authors were able to follow up 48 patients with 71 MISTI Gold implants. The average follow-up was 68 months (range, 10 to 108 months). The retrospective study found that 59 percent of all MISTI Gold implants were removed after an average period of 4.14 years. The main reason for implant removal was an increase in volume of 38 percent, followed by capsular contracture in 14 percent of all 71 MISTI Gold implants. The average increase in volume of all removed MISTI Gold implants was 43 percent. Capsular contracture was graded as Baker I and II in 63 percent and as Baker III and IV in 37 percent. In conclusion, the authors believe that MISTI Gold implants do not fulfill the criteria of safe breast implants, and they agree with the December of 2000 opinion of the Medical Devices Agency of the Department of Health in London that the hydrogel-filled breast implants should not be used until more information about the filler material and its metabolic fate is available.

Medial thigh lift free flap for autologous breast augmentation after bariatric surgery.

BACKGROUND: Massive weight loss following bariatric surgery frequently results in body contour deformities like ptotic and hypoplastic breasts, redundant abdominal tissue and loose skin especially in the medial thigh area. This redundant tissue can be used for breast augmentation in the case of hypertrophic ptotic breasts. METHOD: In 3 patients who underwent a vertical banded gastroplasty and consecutively lost more than 60% of their body weight, a breast augmentation with a transverse gracilis myocutaneous free flap was performed. RESULTS: Bilateral myocutaneous gracilis free flap breast augmentation resulted in an esthetic, pleasing result, with additional correction of the redundant skin from the medial thigh region. CONCLUSION: Autologous breast augmentation with a simultaneous medial thigh lift can be performed safely, after successful weight loss following bariatric surgery.

Functional lower lip reconstruction with bilateral cheek advancement flaps: revisitation of Webster method with a minor modification in the technique.

Major defects of the lower lip have been repaired in many ways. Of these, some employed flaps from the chin, cheek or upper lip. Some of these procedures employed flaps without regard for the facial grooves or landmarks. Some methods required incisions through nerves supplying the orbicularis oris and the flaps used for the lower lip reconstruction. Of the many methods of reconstruction that have been reported, we believe that the Webster technique should be considered as the first choice for lower lip defects larger than 80% of the total. Because this technique interferes minimally with the sensation of the lower lip and a satisfactory cosmetic outcome with a functional lower lip is achieved, the sensation and muscle function of the upper lip are unaffected. In addition to discussing the advantages of the Webster method, in this paper we present a minor modification in the dissection of the orbicularis oris muscle in an attempt to improve the motor innervation and to provide adequate oral competence and labial functioning in expression and speaking. Motor function and innervation of the lips after reconstruction was documented by clinical findings as well as electrophysiological methods.

Unilateral breast enlargement 5 years after reduction mammaplasty.

A 26-year-old woman presented with unilateral breast enlargement 5 years after bilateral reduction mammaplasty. After careful physical examination combined with a clinical assessment, mammogram, and histologic tissue examination, the patient underwent bilateral reduction mammaplasty using an inferior wedge resection technique. Histologic examination confirmed the diagnosis of a fibrocystic breast disease in both breasts. The most common differential diagnoses are juvenile fibroadenoma, virginal hypertrophy, fibrocystic disease, and cystosarcoma phylloides.
