In plastic surgery, clean, elective operations such as breast reductions are anticipated to have low risk factors for infections (1.1-2.1%). To further lower or prevent surgical site infections (SSI), the efficacy of a prophylactic administration of anti-microbacterials remains a current controversial issue in plastic surgery. We report here the findings of a retrospective study in which we examined two groups of patients with breast reductions, one of which received a single-shot antimicrobacterial prophylaxis with cefuroxime preoperatively and the other who were given no anti-microbacterials. The aims were to determine the early SSI incidence of both groups, to classify breast reductions with respect to their inherent SSI risk by two widespread, combined risk scores, i.e., the National Nosocomial Infection Surveillance (NNIS) score and the Study on the Efficacy of Nosocomial Infection Control (SENIC) score, and to compare the actual SSI incidence to the predicted risk of the scores. In the divisions of plastic surgery at two hospitals, 153 patients (group I) and 136 patients (group II) could be included in the study in the 4-year period April 1997 to December 2001. Excluded were all patients with unilateral breast reduction or breast reconstruction and patients who were followed up less than 30 days postoperatively. The two groups were comparable with respect to demographic and clinical features such as age and risk factors, and there were no detectable significant intergroup differences in the general perioperative data. According to the NNIS and the SENIC scores, all operations were "clean," and the American Society of Anesthesiologists (ASA) score was < 3 in all patients. Although the mean duration of the operation was significantly different in the two groups (190 min in group I, 160 min in group II; p < 0.001, Mann-Whitney test; 75th percentile at and 4 and 3 h, respectively), it was longer than 2 h in both groups. The incidence of early infections was 3.9% in the first group, compared with 3.6% in the second group (p = 1.0, odds ratio = 1.07, 95% CI = 0.32-3.6). All infections were local and superficial; no general symptoms were noticed. Three patients had to be readmitted and two of these were reoperated. The rate of infections for both groups was higher than generally anticipated for this kind of clean operations and higher than predicted by the NNIS score for medium risk (predicted risk of 2.9%). The reason for this discrepancy is that the NNIS score is an inpatient risk score which does not include a postdischarge SSI surveillance. Using the NNIS definition of SSI we would have had an infection rate of 0% in both groups in our study. According to the SENIC score, breast reductions can be classified also as medium risk of SSI with a predicted risk of 3.9%, which showed a nearly perfect correspondence with the actual SSI incidence in both study groups. The reason for this increased, medium risk is the factor "operation time > 2 h," which is obviously an inherent risk factor in breast reductions. Among t...

Radiation therapy combined with the sensitizer razoxane is able to control a recurrent AAM for an unknown time. It remains open whether a radiation treatment alone would have had a similar effect.

From a total of 281 patients with protruding ears who underwent a bilateral otoplasty between 1990 and 2001, a group of 28 (10%) was selected for a retrospective quality control study. The goal was to compare two methods of otoplasty, the Francesconi, a cartilage-sparing technique, and the Converse, a cartilage-cutting technique, in terms of objectively measurable and subjectively discernable differences in results. Objective parameters included measurement of the three cephaloauricular distances and the conchoscapal angle. An independent plastic surgeon performed the evaluation by means of a systematic evaluation system for rating cosmetic surgical procedures and a 5-point visual analog scale for rating satisfaction. The patients' subjective rate of satisfaction also was investigated using the 5-point scale. The mean medial and inferior cephaloauricular distances were significantly smaller in the Francesconi group. The concoscaphal angle was 90 degrees, or less in all the patients of the Francesconi group, but more than 90 degrees in eight patients (57%) of the Converse group (p = 0.041). Accordingly, the independent surgeon found adequate correction of protrusion in 86% of the Francesconi group and 50% of the Converse group (p = 0.050). His satisfaction rate was significantly in favor of the Francesconi technique (p = 0.006). Not unexpectedly, the patients' satisfaction rate was comparably high in both groups, and there was no statistical difference between them. In conclusion, the quality control led to a clear preference of the Francesconi over the Converse otoplasty. In addition, the assessment of the postoperative results with the systematic evaluation system offered an excellent information base by which to judge the results of otoplasty. Consequent use of this evaluation system will lead to progress in the surgical procedure.
