OBJECTIVETo determine if miniprostheses would form a capsule of significantly different biophysical, biochemical and histologic properties than the conventional silicone implant.

METHODSFour miniprostheses (experimental group) and one big silicone implants (control 1 group) were separately implanted beneath the panniculus carnosus muscle of 30 rabbits. After 3 months, measures related to contracture and capsular histology were performed on anesthetized animals.

RESULTSBaker ranking, capsular incision width and capsular thickness of the control groups were evidently higher than that of experimental groups (P < 0.01). Implant compression of the control groups was evidently lower than that of the experimental group. Histology revealed a thinner, more flexed capsule around the miniprostheses as compared with big silicone implants.

CONCLUSIONSThe miniprostheses form a looser and thinner capsule than the conventional silicone implant.

OBJECTIVETo inquire into the reason why the postoperative complications of augmentation mammaplasty by injecting polyacrylamide hydrogel took place and to find the best method to deal with the complications.

METHODS12 patients who accepted polyacrylamide hydrogel injection for augmentation mammaplasty were included in this study. Operations were performed to remove the polyacrylamide hydrogel.

RESULTSAll patients didn't argue with the result, but the outside shape of mamma was not good post-operation.

CONCLUSIONSSo-called standard injection method can't avoid the postoperative complications. The considerable therapy for the complications of polyacrylamide hydrogel was removing it by operation.

OBJECTIVETo investigate the complications in 16 patients who had breast augmentation with polyacrylamide hydrogel injection. The distribution and late changes of the injected material was observed.

METHODSThe physical signs and symptoms of the 16 patients were classified. Ultrasound and infrared examinations or MRI were used in some cases.

RESULTSTwo patients had operations for extraction. The injection material was distributed in the muscles diffusely, or existed in the breast and subcutaneous tissue as many masses.

CONCLUSIONThe reliability of this injection method for breast augmentation is in doubt.

OBJECTIVETo analyze the effect of acellular dermal matrix (ADM) on complications of breast reconstruction using tissue expander/implant, and to offer preliminary evidences for ADM clinical application.

METHODSArticles published from Jan. 2010 to Oct. 2012 were searched in Pubmed, EMbase, Science Direct and CNKI database. Literatures were filtrated according to inclusive criteria. Values were extracted from included literatures; factors regarding complications were collected. Meta-analysis was performed with Stata 12. 0.

RESULTS10 researches were included. Comparing to control group, the pooled odds ratio (OR) of overall complications, infections, hematomas/seromas, explantations are 1.51(P=0.038), 1.91(P=0.032), 1.80(P=0.005) and 2.37 (P=0.138) in ADM group In breast reconstruction using tissue expander/implant, ADM increases the respectively.

CONCLUSIONSoccurrence of hematomas/sarcomas as well as risks of infections and overall complications.

OBJECTIVETo investigate the bad effect of breast augmentation with PAAH injection and the technique to remove PAAH from breast effectively and safely.

METHODS43 cases (86 sides) underwent operation to remove the PAAH from breast through submammary incision, followed by dressing with pressure for 3 days. The patients received colored doppler ultrasonography and immunologic test before and 3 months after operation.

RESULTSPostoperative ultrasonography showed residual PAAH in breast in one case. Among the 20 cases who had preoperative breast pain, the pain relieved completely in 10 cases and improved in the other 10 cases. All the patients had some abnormal results in immunologic test which improved 3 months after operation.

CONCLUSIONSBreast augmentation with PAAH injection can result in breast pain and other complications. It may also have bad effect on the immune system. PAAH should be removed as soon as possible. The technique through submammary incision to remove PAAH is one of the safe and reliable methods.

OBJECTIVETo discuss the complications of breast augmentation with injected polyacrylamide hydrophilic gel (PAHG) in order to avoid further injury by taking treatment at the right moment.

METHODS90 patients with some side-effects after breast augmentation with injected polyacrylamide hydrophilic gel had been undergone the treatment in our hospital from 1999 to 2006. Their clinical data were analyzed.

RESULTSThe major complaints of the patients were feeling pain, multiple indurations, secondary deformity, PAHG displacement, low-grade fever of unknown reason, limitation of upper limb activity, spillage of milk and blood, ulceration and sinus tract of breast, inversion of nipple, infection. All patients were treated by surgical operations to remove the injected PAHG.

CONCLUSIONSThe complications are might not only related to the injected material but also caused by incorrect manipulation during operation. To do suction several times may cause the injected material distributed diffusely and the tissue was badly injured. Operation can remove the PAHG as completely as possible. It is a better treatment for the complications of PAHG injection for augmentation mammaplasty.

OBJECTIVETo investigate the correction of secondary breast deformities after removement of injected polyacrylamide hydrophilic gel (PAHG).

METHODSFrom March 2003 to March 2008, 100 patients with bilateral breast augmentation with injected PAHG underwent operation to remove the PAHG. The age of patients ranged from 35 to 50 years. Ultrasound and MRI were performed before operation to show the distribution of PAHG and the muscle infiltration around the PAHG. According to the PAHG distribution, muscle infiltration, skin elasticity, infection and PAHG residue, the patients were treated respectively with breast implants at the same stage or at the second stage, or without implants.

RESULTSThe patients were followed up for 3 months to 3 years. The percentage of satisfactory, median satisfactory and dissatisfactory was 90%, 9%, and 1%. In the median satisfactory group, 3 breasts in 3 cases showed slight capsular contracture (Baker II), 8 implants in 6 cases were palpable on the lower pole of the breasts. The middle-aged patient in dissatisfactory group was not satisfied with the high-projected implants shape which were chosen by herself and placed at the second stage. Then implants were removed. There was no complication of implant hernia, infection, wound disruption, or asymmetry.

CONCLUSIONSThe secondary breast deformities could be corrected by breast augmentation with implants. Both breast appearance and the psychological affection can be improved.

OBJECTIVETo explore the relationship between mammaplasty and results after polyacrylamide hydrophilic gel (PAHG) removal from breast.

METHODSFrom Feb. 2003 to Aug. 2009, 130 patients with bilateral breast augmentation by PAHG injection were treated. Preoperative ultrasound examination and MRI were performed to know the distribution of PAHG and infiltration at the surrounding tissue. According to the conditions after removal, the patients were received implant augmentation immediately, or at the second stage, or no implant.

RESULTSThe patients were followed up for 3 months at the most with a very satisfactory rate of 63.84% (83/120), a satisfactory rate of 31.53% (41/120) and a unsatisfactory rate of 4.63% (6/120). Slight capsular contracture (Baker I) occurred in 5 cases with 6 breasts in satisfactory group. All the patients in unsatisfactory groups who selected unsuitable implants by themselves were re-operated to take out the implants. 3 cases with much residue PAHG insisted to receive breast implants. Among them, 2 cases achieved acceptable results even the surface of the breasts were not smooth. No other complication happened.

CONCLUSIONSThe breast reaugmentation after PAHG removal should be performed based on the deformity and condition of breast. Both cosmetic result and psychological relief could be obtained after mammaplasty.
