Background: Since its original description in 1979, the Moufarrege total posterior pedicle reduction mammaplasty technique has proven to be a safe and reliable procedure providing aesthetic and functional enhancement.

Objectives: To determine if the Moufarrege total posterior pedicle reduction mammaplasty affects successful breastfeeding.

Method: Retrospective chart review was performed for patients operated on between 1981 and 1997, and a written questionnaire was given. Patients were asked about their ability to lactate and successfully breastfeed preoperatively and postoperatively. The t test and χ(2) test were used to compare means and categorical variables, respectively. Values were also compared with a sample of women (n = 2223) from the Quebec general population as collected by the Longitudinal Study of Child Development in Quebec (ELDEQ, 1998-2002).

Results: A total of 931 patients (all women) underwent reduction mammaplasty during the study period at Jewish General Hospital, Montreal, Quebec, Canada (H.S.) or Hopital Hotel-Dieu, Montreal, Quebec, Canada (E.B. and R.M). There was a 62% response rate to the questionnaire. There were no statistically significant differences in the percentage of women able to lactate postoperatively vs preoperatively (98% vs 100%, respectively; P = .2). The percentage of women able to successfully breastfeed for 4 and 6 months was also not statistically different when comparing postoperative vs preoperative ability (4 months: 33% vs 44 %, P = .13; 6 months: 29% vs 28%, P = .77). The sample of women from the Quebec population did not differ statistically from those undergoing the Moufarrege breast reduction in terms of successful breastfeeding for 1, 2, 3, and 4 months (59% vs 67%, 52% vs 47%, 42% vs 41%, and 40% vs 33%, respectively).

Conclusions: The Moufarrege breast reduction technique is a reliable and safe procedure that does not seem to negatively affect the success of breastfeeding based on the results of our retrospective chart review and patient questionnaire.

Personalized implant for high tibial opening wedge: combination of solid freeform fabrication with combustion synthesis process.

J Biomater Appl 2012 Sep 12;27(3):323-32. Epub 2011 Jul 12.

In this work a new generation of bioceramic personalized implants were developed. This technique combines the processes of solid freeform fabrication (SFF) and combustion synthesis (CS) to create personalized bioceramic implants with tricalcium phosphate (TCP) and hydroxyapatite (HA). These porous bioceramics will be used to fill the tibial bone gap created by the opening wedge high tibial osteotomy (OWHTO). A freeform fabrication with three-dimensional printing (3DP) technique was used to fabricate a metallic mold with the same shape required to fill the gap in the opening wedge osteotomy. The mold was subsequently used in a CS process to fabricate the personalized ceramic implants with TCP and HA compositions. The mold geometry was designed on commercial 3D CAD software. The final personalized bioceramic implant was produced using a CS process. This technique was chosen because it exploits the exothermic reaction between P₂O₅ and CaO. Also, chemical composition and distribution of pores in the implant could be controlled. To determine the chemical composition, the microstructure, and the mechanical properties of the implant, cylindrical shapes were also fabricated using different fabrication parameters. Chemical composition was performed by X-ray diffraction. Pore size and pore interconnectivity was measured and analyzed using an electronic microscope system. Mechanical properties were determined by a mechanical testing system. The porous TCP and HA obtained have an open porous structure with an average 400 µm channel size. The mechanical behavior shows great stiffness and higher load to failure for both ceramics. Finally, this personalized ceramic implant facilitated the regeneration of new bone in the gap created by OWHTO and provides additional strength to allow accelerated rehabilitation.
