Background:
The purpose of this study was to determine whether the aesthetic results of subpectoral augmentation mammaplasty using anatomically shaped versus round prostheses are differentiable.
Methods:
Thirty observers (i.e., plastic surgeons and nurses) assessed preoperative and postoperative photographs (frontal and oblique views) of 30 patients who had undergone subpectoral augmentation mammaplasty with cohesive silicone gel implants, with an average implant volume of 295 cc (range, 220 to 340 cc). The observers classified each case as round or shaped on two different occasions with a 12-week time interval. A statistical concordance analysis was performed, calculating the overall concordance rate, the interobserver, the intraobserver, and the overall intraobserver kappa indexes, to evaluate the expert observers’ capacity to differentiate the implant type.
Results:
Among the total of 1800 observations (30 observers assessed 30 cases on two occasions), the overall concordance rate was 50.33 percent (95 percent CI, 47.99 to 52.67). The interobserver kappa value was 0.010 (95 percent CI, 0.0025 to 0.04). The overall intraobserver kappa value was 0.0602 (95 percent CI, 0.0025 to 0.123). The observers were unable to recognize the type of implant used, nor was interobserver concordance noted. An agreement was not reached before the different observers, nor was an intraobserver concordance seen between the first and second classifications of the same cases by each observer.
Conclusion:
The results obtained from subpectoral augmentation mammaplasty using anatomically shaped and round prostheses with a volume of 340 cc or less are indistinguishable, not justifying the systematic use of anatomically shaped implants in this patient.

Los fluoruros se han utilizado durante décadas para prevenir la caries y su eficacia está aceptadaaunque no así su vía de administración. Actualmente se preconiza la utilización tópica de loscompuestos de fluoruro para maximizar sus beneficios y minimizar sus riesgos. La utilizaciónracional de la vía tópica entraña la educación de la población y un cambio en los profesionalesde la salud para asumir que preparados como las pastas dentales y los colutorios que se consideranproductos cosméticos son medicamentos con riesgos ciertos si no se utilizan adecuadamente. Laconcentración excesiva del preparado activo y la ingesta sistemática de pequeñas cantidadespueden desarrollar fluorosis si ocurre cuando el niño no ha completado la formación de suscoronas dentarias. Asimismo, la ingestión de cantidades importantes pero posibles puede darlugar a un accidente agudo de carácter grave. Los médicos pediatras y en general los profesionalesde la salud deben conocer los beneficios y riesgos de estos preparados, determinar la ingestatotal de flúor de cada uno de sus pacientes y prescribir los que están indicados. Los padres tienenque comprender que los preparados tópicos a base de fluoruro son medicamentos y deben sermanejados como tales siendo ellos responsables de que no ocurran accidentes por mal uso. Losfabricantes deberían modificar sus estrategias comerciales y evitar envases de contenido excesivoasí como incluir información detallada sobre sus componentes, tanto del principio activocomo del contenido de alcohol.
