Changes in breast sensibility after reduction mammaplasty remain a controversial subject and most previous studies report only qualitative results. There is more accurate measuring of the sensibility of the skin with the Pressure-Specified Sensory Device (PSSD), which measures the pressure perception of the skin in grams per square millimeter. The evaluation of breast sensibility before and after reduction mammaplasty using the upper medial pedicle technique was undertaken in 25 patients. The PSSD was used to measure one dynamic point threshold in nine points of the breast during the preoperative period and 6 months after surgery. After surgery all patients had decreased sensation in all points studied, and this was significant. There are few reports of breast sensibility after mammaplasty using the PSSD, and the discrepancy in results reported using other methods of evaluation could be related to precision in evaluation.

The distinctive anatomic features and topography render the ear unique in the human body. Total or partial reconstruction of the ear may be required in many clinical conditions, but because technical difficulties are common, the rate of postoperative complications increases. Objectives: To analyze the epidemiologic data of patients who underwent surgery for reconstruction of the ear due to congenital conditions (microtia) or acquired deformities (trauma, burns and others), and to compare the results in order to define which group had the lowest rate of complications. Methods: A retrospective analysis was conducted with 279 cases of ear reconstruction performed between 1994 and 2004 by the Discipline of Plastic Surgery of the University of São Paulo Medical School. The patients were initially separated in two groups, according to their condition (congenital or acquired), to compare their data. Results: Male was the prevailing gender in both groups of ear deformities: congenital (61.3%) and acquired conditions (68.7%). The patients with congenital deformities had a mean age of 14.3 years at the beginning of the treatment, whereas the patients with acquired deformities were 29.5 years old, in average. The major causes of acquired deformities were trauma (55% of the cases in this group) and burns (29%). The only cause of congenital deformity observed was microtia. Patients required an average of 4.2 surgical procedures. However, those with sequelae of burn injuries were submitted to a significantly higher number of procedures (5.9-p<0.01). Cartilage exposure (15.1% of the total) and postauricular bridles (16.5%) were the major complications observed in this study. The latter was more common among those cases with microtia and sequelae of burns. Conclusions: Patients with traumatic injuries had a better outcome after surgery than those with microtia or burn injuries, because of a lower rate of complications.
