  ABSTRACT: A study was performed to investigate histological changes in capsules formed around silicone breast implants and their correlation with the clinical classification of capsular contracture defined by the Baker score. For histological classification, the authors used the classification introduced by Wilflingseder, which identifies four grades of contracture. The study included 24 female patients (average age, 40 +/- 12 years) with capsular contracture after bilateral cosmetic breast augmentation with smooth silicone gel implants (Mentor, Santa Barbara, Calif.). The Baker score was determined preoperatively for each patient. Samples of capsular tissue were obtained from all patients for histologic and immunohistochemical analyses. Capsular thickness, age of the collagen fibers, presence of synovia-like metaplasia on the inner surface of the capsule, number of histiocytes, giant cells, and other inflammatory cells, amount of silicone, foreign body granulomas, and capsule calcification were evaluated. There was a positive correlation between capsular thickness (p < 0.05) and Baker score. Silicone-containing deposits were found in all four histological capsule types. A trend toward greater capsular thickness was documented in patients with severe inflammatory reaction. These patients also had more clinical symptoms. Greater capsular thickness was associated with a higher number of silicone particles and silicone-loaded macrophages in the peri-implant capsule. The authors demonstrated a positive correlation (p < 0.05) between the clinical classification (Baker score I to IV) and the histological classification introduced by Wilflingseder (Wilflingseder score I to IV). An exact histological classification is needed to describe precisely the morphological changes in capsular contracture.

• Article: Modification of the second stage of auricular elevation in Nagata's technique for treating microtia.

  ABSTRACT: The ultimate goal in treating congenital microtia is the reconstruction of an auricle with a natural appearance as close as possible to the healthy one in terms of shape, contour, size, texture, position, and projection. Here we present another option to the second stage of raising the ear in Nagata's technique for treating microtia. The first step includes implantation of a cartilaginous framework and transposition of the ear lobe. Raising the cartilage leaves a skin defect behind the auricle. Instead of using a superficial temporoparietal fascia flap as described by Nagata, we raise a simple rotation flap from the mastoid and neck to close the defect with a minimal scar. The advantages of this technique include firm elevation, good frontal projection, and a natural appearance of the auriculo-cephalic sulcus with a normal retroauricular hairline. In addition, the procedure fast and practical, creates no additional scars on the scalp, and preserves the superficial temporoparietal fascia.
