Mastopexy following Explantation
number of reports of palpable or mammographically detectable masses present in the breast following explantation when the capsule had been left
presence of residual silicone particles within the capsule
dissection of a subpectoral implant is more difficult than that of a subglandular (risk of pneumothorax)
Postoperatively, the breast mound drops inferiorly producing a glandular or pseudoptosis.
Options after explantation
explantation alone
implant exchange
mastopexy with implant
mastopexy alone.
Rohrich Algorithm for mastopexy alone post explantation
OTHER CONSIDERATIONS
Parenchymal Transposition Flaps of lower pole breast tissue to the upper pole to attain fullness above.
IMF is formed by attachment of the dermis to the underlying fascia. To re-position the crease, these attachments need to be divided and re-created with sutures.
Skin Patients with inelastic, striated skin receive minimal lasting support from skin tightening. The skin below the NAC bears the brunt of the force and heals slowly, especially if the patient is a smoker.
Lateral folds will become more prominent post-op and therefore must be dealt with as part of the plan.
COMPLICATIONS
EARLY
1. Haematoma: Uncommon. If large - return to theatre.
2. Infection: Uncommon - associated with poor vascularity - smokers etc.
3. NAC Necrosis: Uncommon - only occasionally seen in heavy smokers.
LATE
1. Asymmetry: May need revision.
2. Recurrent Ptosis The most common problem following mastopexy. Often associated with weight loss. A loss of 5kg will significantly be reflected in breast shape. It is said to occur most predictably with “skin only” mastopexy where the lower pole ptotic breast tissue is not excised at the initial procedure.
3. Upper pole flattening: Should be noted in pre-op assessment. Treated with appropriate sized implants.
4. Implant Related Problems
5. Scar problems
LONG TERM RESULTS
Mastopexy is a temporary procedure - one should expect some recurrence with time.
Patient satisfaction is directly related to pre-operative decisions - the more time spent discussing the options with the patient pre-operatively, the less likely the need to justify the result.
CONCLUSIONS
1. Mastopexy is not a single operation but rather one that must be individualised to fit the patient’s deformity and desires. It bridges the spectrum of aesthetic breast surgery from augmentation to glandular reduction.
2. None of the currently accepted techniques are without problems. None of the solutions are permanent and there is always a trade off to be made - scars +/- implants.
3. As with any aesthetic procedure, careful pre-operative assessment - both physical examination and discussion of aesthetic goals with patient, will minimise the problems post operatively.
4. For the minor ptosis - augmentation +/- NAC elevation appears to give the most satisfactory results.
5. For more severe ptosis, lower pole resection and augmentation to achieve upper pole fullness offer the best and most predictable long term results.
MASTOPEXY
Essentially aesthetic in nature so consideration of scarring is critical
Classification of Ptosis —Regnault
I nipple descends to level of inframammary fold
II nipple below fold but above lowest contour of breast
III nipple reaches lowest contour of breast
Pseudoptosis—loose, lax breast with nipple above inframammary fold
Majority of gland is below IMF
Ptosis is also a lateralization of the breast
Grabb and Smith pg 744
Nipple—IMF > 7cm ptosis that can’t be corrected by implant alone
Benelli Round Block Mastopexy +/- reduction
Best for moderate ptosis and small reductions (<250gm)
+/- reduction or augmentation
reshape gland and redrape without tension (tension flattens breast)
mark midline and breast meridian
sup margin of new nipple point 2cm above IMF
less skin excision laterally than medially
excision appears elliptical when standing and round when lying
de-epithelialise
s/c flaps raised to IMF
elevate sup dermoglandular pedicle and divide inferiorly the remaining breast to create lat
and med glandular flaps
resection for reduction as necessary
if poor quality gland of low volume—no flaps raised—inferior gland plication only
glandular flaps arranged to reduce size of base of breast and provide conical shape
suspend superior flap to deep fascia
lat and medial flaps folded to midline—usually lat over med to medialise the breast
this also reduces the base of the breast—more conical
breast lacing suture to maintain shape—with straight needle
round block cerclage stitch to prevent pull and widening of areola (Mersilene)
Goez modification
Less of a sup dermoglandular flap
Central mound pedicle
Absorbable mesh (Vicryl) over gland
Ide-ep skin is used to suspend breast to pec fascia and surround gland—it lies over
the top of the Vicryl mesh
PTOSIS
Caused by post-partum involution of gland, volume loss after weight loss or lax stretching skin
Stretching of Cooper’s ligaments
Due to discrepancy between volume and envelope
Correction can be increase volume
Reduce envelope
Combination
Augmentation mastopexy is a combination
Ideal
Sternal notch to nipple 19-25cm
Equilateral triangle nipple—nipple—sternal notch
Nipple to IMF 4-8cm
Mild ptosis increase volume alone
Smaller scar
Less affect on sensation
If more severe ptosis—increase volume alone and accept some residual ptosis
Moderate and Severe ptosis require augmentation mastopexy
Superior crescent mastopexy
Elevates NAC a little
Can excise small sup component of areola to account for post-op areolar stretch
Doesn’t address envelope
Concentric Mastopexy Benelli
If truly concentric—won’t elevate nipple
Will reduce envelope
Can reduce areolar diameter
Eccentric Mastopexy
Nipple elevation—mild
Reduces envelope
Can reduce Nipple projection
Vertical Scar
More reduction in envelope
More elevation of nipple
Minimal scar—vertical
Inverted tear drop skin excision
Minimise skin excision initially as implant takes up envelope
? lower IMF
Formal Mastopexy
For advanced ptosis
Wise pattern or incision wide enough to excise NAC and then raise flaps and resect as
appropriate
Wise pattern with minimal angle—enough to excise NAC and long limbs
Place nipple at IMF or up to 2cm above
Raise skin flaps superiorly to level of new nipple, not further
Insert implant and redrape skin
