Immediate Vs Delayed Breast reconstruction – Benefits & Risks
![Page 7: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/7.jpg)
Immediate
•Better aesthetic result•Better psychological effect•Lower cost
•Higher risk of complications independently the method of reconstruction
•Lower complication rate•Less optimal result
•High percentage of anxiety, depression and impairment of their sexual attractiveness
•Higher cost (2 operations, hospital stays)
Delayed

What is the effect of radiation on Implant
based breast reconstruction?
![Page 11: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/11.jpg)
The objective of this meta -analysis is to examine:
whether patients requiring post-mastectomy radiotherapy should have an immediate or delayed reconstruction
whether a prosthesis or autologous reconstruction is associated with the optimum outcome in terms of postoperative morbidity
![Page 12: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/12.jpg)

conclusion Post-mastectomy radiation, irrespective of the method
of reconstruction, increases the incidence of postoperative complications; however, this study demonstrates that an autologous flap offers a more favorable outcome in terms of morbidity than expander/implant reconstruction

Can we always know if RT is going to be followed?

Indication for Post-mastectomy RT Many decisions regarding radiation therapy are made after mastectomy
•T3 or T4 tumors or four or more positive axillary lymph nodes needs RT•Radiation in T1 or T2 tumors and one to three positive axillary nodes is controversial.
•fine-needle aspiration instead of open excisional biopsy techniques, has limited the ability to diagnose the amount of invasive tumor within the breast parenchyma compared to the permanent section
•sentinel lymph node biopsy cannot detect lymph node micrometastases

Benefits of Delayed-Immediate Breast Reconstruction
Avoid problems associated with PMRT after an immediate breast reconstruction.
Better aesthetic outcome than is achieved with standard delayed reconstruction. Specifically, re-expansion of the mastectomy skin after PMRT provides additional usable breast skin to perform delayed breast reconstruction.
Provides an additional option that broadens patients’ treatment choices and allows patients to participate fully in treatment and reconstruction decisions.

Tissue expander under the pectoralis major + 150 (+- 25 cc) of fat in the upper quadrants between the skin and the muscle and also inside the muscle
In the 1st operation
In the 2nd operation After 3 months, removal of expander, insertion of the cohesive silicone prosthesis, and injection of 150 (+-30 cc) of fat in the lower quadrants

Mean follow-up was 1 year.
No complications were recorded with the fat injections.
Patients’ mean satisfaction rating was 4 on a scale of 1 (low) to 5 (high), and the capsularcontracture was never above 1 on the Baker classification

Plastic and Reconstructive Surgery • August 2011
From 2000 to 2010, the authors reviewed 646 lipofilling procedures from 513 patients
The average follow-up time from the last lipofilling procedure to the last visit was 19.2 months (range, 1 to 107 months)
12 radiologic images appeared after lipofilling:
From 7 histopathologic reports:
7: Benign calcifications2: Benign opacity masses3 :Suspicious lesions
5: Benign lesion2: Local breast relapse
![Page 24: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/24.jpg)
Conclusion
Lipofilling following breast cancer treatment leads to a very low rate of complications
Does not affect the radiologic follow-up
There is no proof of the safety of lipofilling in terms of cancer recurrence or distant metastasis
Lipofilling should be performed in experienced hands, and a cautious oncologic follow-up protocol is advised

Pharmacologic Agents
Leukotriene antagonists (LTRAs) have emerged as effective prophylactic agents in the management of reactive airway diseases
Montelukast and Zfirlukast have “Off-Label” use in Breast Augmentation
They seem to prevent and improve the Capsular Contracture
There are no series of using these agents in breast reconstruction
with RT
![Page 26: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/26.jpg)
Pharmacologic Agents
Impact Factor: 1.389
In our Hypotheses we suggest that the Zafirlukast is able to prevent the post-radiation capsular contracture by blocking the TGF which plays key role in radiation induced fibrosis

Limitation of Other Implant Techniques
Total Muscle Cover Difficult Painful Bloody Limited space Poor shape Poor IMF definition Superior malposition
Partial Muscle Cover Implant migration More infections? More contractures? More exposures? More explantation
![Page 29: Implant-Based Breast Reconstruction](https://reader034.vdocuments.net/reader034/viewer/2022042604/58a451ed1a28ab55068b5619/html5/thumbnails/29.jpg)
Benefits of AlloDerm
• Technically easier than total muscle cover
• Less morbidity than total muscle
• Better shape than total muscle
• Better control of folds and shape than total muscle only
• Less capsular contraction

Plastic and Reconstructive Surgery • December 2010
Twenty patients underwent tissue expander reconstruction using the “dual-plane” acellular cadaveric dermis technique (AlloDerm). During implant exchange, intraoperative biopsy specimens were obtained of (1) biointegrated acellular cadaveric dermis and (2) native subpectoral capsule (internal control).

The key points of our technique are:
• advantages of Alloderm
•eliminate the “Step- off” deformity
•Recreate the normal tail of the breast toward the axilla

Results 7 patients required surgical intervention to the
contralateral breast for symmetry achievement.
Mean follow-up was 1 years (ranged from 6 to 17 months) Two patients with infection in the early postoperative
period required expander removal (5.4%). No complications were noticed after fat injection. During the follow-up period the capsular contracture
was never above 1 on the Baker classification
