Histopathological findings in surgical specimens obtained from reduction mammaplasties.

The objective of this study was to check the histopathological findings following reduction mammaplasty. A total of 274 patient files were reviewed retrospectively. All women ascertained were divided into three groups by age. All of them had undergone reduction mammaplasty between January 1987 and December 2002. Breast tissues resected during surgery were submitted to histopathological examination. Benign lesions were more frequently encountered than any other type of breast pathology. Dysplasia and fibroadiposity accounted for 69.1% of the lesions found, most being in group 1. Atypical ductal hyperplasia was found in 0.6% of cases. The frequency of carcinoma was 1.1%. The prevalence of ductal carcinoma was 0.6%, and most of these cases were in group 3. It was observed that the age group with the highest number of histopathological lesions was that of women younger than 35 years of age and that benign lesions were the most common kind. Lack of pathological investigation or a cursory or hurried examination of any mammary tissue by the pathologist may cause important lesions to be overlooked.

Breast pathology and reduction mammaplasty.

Breast cancer is the tumor with the highest prevalence and incidence in women. Reduction mammaplasty is one of the most common procedures performed in Brazil by the plastic surgeon, and it is not uncommon for the surgeon to find a breast tumor during the operation or afterward, when the histopathological report is received. In this study, 2488 patient files were reviewed retrospectively. All patients had undergone reduction mammaplasty at the senior author's private clinic (the Ivo Pitanguy Clinic) between January of 1957 and December of 2002. Resected breast tissue was examined histopathologically. The objective of this study was to verify the occurrence of breast carcinoma found accidentally postoperatively. The senior author's team performed all of the operations and the same pathologist performed every histopathological examination. The histopathological test results were divided into two groups: benign lesions and tumors. The highest frequency of breast pathology was benign lesions, and of them, 80.8 percent involved fibrocystic changes and fibroadiposity. The tumor group was subdivided into benign tumors and malignant tumors. Among the benign tumors, fibroadenoma was the one most common, in 2.2 percent. The frequency of malignant tumors was 0.5 percent of all patients. Most of the histopathological lesions were found in patients between 30 and 50 years of age. A reduced number of patients had no lesions (3.7 percent). Lack of a pathological investigation or a cursory or hurried examination of any mammary tissue by the pathologist may overlook important lesions. In the analysis of these statistics, the concept of normal breast tissue was questioned.

Forehead lifting: the juxtapilose subperiosteal approach.

Aging in the upper face becomes more evident as the eyebrow level descends. Sometimes this may begin at an early age. The senior author has described a limited approach for the treatment of this aesthetic alteration. In selected cases, the juxtapilose incision, placed laterally at the margin of the anterior hairline, allows for the subperiosteal undermining of the entire forehead and dissection of the elements that cause the descent of the eyebrow. The procedure is safe and expedient, and permits for a controlled repositioning of the eyebrow. In this paper, the authors describe the juxtapilose incision and the subperiosteal approach of the forehead as a practical ancillary procedure for correction of the aging face.

[Body-contouring surgery].

Concepts of beauty have been continuously evolving throughout the history of mankind. The voluptuous figures that were idealized by artists in the past have been substituted by slimmer forms. Medical advances in this century have permitted safe and efficient surgical correction of contour deformities. Until recently, these alterations were mostly hidden under heavy clothing or were reluctantly accepted. Current fashion trends generally promote body-revealing attire. The media frequently encourages the importance of fitness and good health linking these qualities with youthfulness and beauty. The subliminal as well as overt message is that these are necessary and desirable requirements for social acceptance and professional success. On the other hand, current sedentary lifestyle and dietary excesses, associated with factors such as genetic determination, pregnancy and the aging process, contribute to alterations of body contour that result in the loss of the individual's body image. This creates a strong psychological motivation for surgical correction. Localized fat deposits and skin flaccidity are sometimes resistant to the most sincere efforts in weight loss and sport activities. This ever-increasing request for contour surgery has been favorably met by safe and effective anesthesiology as well as efficient surgical techniques, resulting in a high degree of patient satisfaction. It is essential that today's aesthetic surgeon understand the motivations of patients who present with body contour deformities. A request for surgical treatment should be seen as a legitimate desire to achieve a physical form that approximates the individual with his or her ideal self-image. Additionally, the surgeon must always consider the possible benefit of including the participation of a multidisciplinary team approach. Depending on each case, this team should include consultants in endocrinology, dermatology, oculoplastics, pediatrics and other appropriate specialties.

Repeated expansion in burn sequela.

This paper presents a retrospective study of the use of 346 expanders in 132 patients operated at the Ivo Pitanguy Clinic, between the period of 1985 and 2000. The expanders were used in the treatment of burn sequela. In the majority of cases, more than one expander was used at the same time. In 42 patients, repeated tissue expansion was done. The re-expanded flaps demonstrated good distension and viability. With the increase in area at each new expansion, larger volume expanders were employed, achieving an adequate advancement of the flaps to remove the injured tissue. The great advantage of using tissue re-expansion in the burned patient is the reconstruction of extensive areas with the same color and texture of neighboring tissues, without the addition of new scars.

Follicular transplantation for the correction of various stigmas after rhytidoplasty.

BACKGROUND: Rhytidoplasty may cause permanent and unwanted stigmas, such as dislocation of the temporal and cervical hairline. Widened scars inside the hairline may cause considerable social embarrassment. Furthermore, pretrichial incisions, even if well placed, may widen or become hypochromic, thus revealing that an aesthetic procedure has been performed. Various procedures for the correction of these undesirable telltale signs of a face-lift have been published. This report aims to present the results of correction for postrhytidoplasty stigmas using follicular transplantation. Patient assessment is discussed, and relevant technical aspects are detailed and illustrated. METHODS: A prospective study at the Ivo Pitanguy Clinic investigated patients who underwent hair transplantation to correct unaesthetic signs secondary to rhytidoplasty from January 2001 to December 2004. The aesthetic results and complications were evaluated, as well as the patients' satisfaction rate. The patients presented in this series either were referred from another service or had their rhytidoplasty originally performed in the authors' service. RESULTS: A total of 33 female patients were included in this study. Two patients were lost to follow-up evaluation and not included. The complications were minor. In the late follow-up assessment, 24 patients classified the result as excellent, 4 as satisfactory, and 3 as unsatisfactory. Only the patients who classified the results as unsatisfactory requested a second procedure (i.e., another follicular transplantation). CONCLUSIONS: When performed by an experienced surgical team, the follicular unit transplantation technique is a simple, safe, and efficient way to correct stigmas secondary to a rhytidoplasty, such as a visible scar or a displaced hairline, with satisfactory results and a very low complication rate.
