Q

describe physical exam for consult for breast hypertrophy / breast reduction

A

Specific

  • examine when standing and follow footprint/conus/envelope/symmetry

A
  • Top of neo-nipple:
    • IMF translated and marked on anterior surface of breast
    • 20-21 cm (small-moderate size breasts)/22-26 cm (larger breasts)
    • Midhumeral height
    • 10cm inferior to superior border of footprint (Hall-Findlay)

Q

describe how you will make skin markings for wise-pattern skin for reduction mammoplasty

A
  • Always mark conservatively à can take skin and narrow pedicle later
  • Patient standing/sitting
  • Measure: SN-N, N-IMF
  • Midsternal line, breast meridian, IMF
  • Top of neo-nipple:
    • IMF translated and marked on anterior surface of breast
    • 20-21 cm (small-moderate size breasts)/22-26 cm (larger breasts)
    • Midhumeral height
    • 10cm inferior to superior border of footprint (Hall-Findlay)
  • Upper border of areola should be ~2cm above position of new nipple (point 1)
  • +/- Template used to make markings; 14cm circumference = 4.5 cm areola
    • 7cm across and 4.5cm height, with 4cm gap at bottom of mosque (to free-hand areola marking)
  • Vertical limbs: lines drawn down from neo-NAC marking ~ 5-6cm in length (line 2)
    • range=5-8 cm in length, depending on current / desired size of breast
    • width btwn limbs: 9 – 11 – 13 (for small, mod, large anticipated breast / reduction)
    • a + b > c; C line laterally to anterior axillary line and medially to ptotic corner
    • If inferior pedicle, width=>8-10 cm (approx 1:2 width:length – ie measure N-IMF)

Q

describe skin markings and pedicle selection/marking for circumvertical reduction mammoplasty

A
  • Patient standing/sitting
  • IMF, Midline, breast meridian to intersect IMF
  • Neo-nipple position
    • previous 4 markers (esp anterior transposition of IMF) = Superior margin of neo-_areola_ (Pt A) vertical reduction gives more projection
  • Top of mosque at desired superior margin for neo-NAC
    • When pt C & D converge, will form a circle
    • Mosque ~4cm in height, 7cm in width – goal areola 4-5 cm diameter
    • Lista - blocking triangles from C to D à prevents teardrop deformity of NAC
  • Breast moved laterally & superiorly, vertical line drawn down from mosque
  • Breast moved medially & superiorly, vertical line drawn down from mosque
  • 2 lines should converge to a point (Point B) ~2-4cm above IMF
    • Larger reduction: Point B higher above IMF
    • Inferior vertical incision can be rounded (Lejour/Hall-Findlay) or point of ellipse (Lista)
  • Technical points
    • Superior or medial pedicle (depends on NAC elevation/rotation)
      • NAC below line D-C = medial pedicle (or lateral)
      • Any part of NAC above line D-C = superior pedicle
      • This limits pedicle length, preventing NAC compromise
      • Pedicle base: 6-8 cm
      • Pedicle creation: 1 cm of tissue around areola

Lateral and medial pillar preservation and approximation (pillar stitches) to give conical shape. Most inferior pillar stitch >4cm above inferior point of incision to prevent dog ear

  • +/- Vertical incision gathering (to shorten)
    • “Box” stitches starting at distal end (Lista)
    • Bunched subcuticular suture
  • Simultaneous SAL possible – infiltration prior to incisions with tumescent solution
  • May incorporate a short transverse scar to eliminate distal vertical dog-ear

    • Significant systemic diseases that may impair blood flow
    • Patients with previous operations or chest wall radiation that may impair blood flow
    • Patients requiring short anesthesia times

Q

discuss treatment of complications

A
  • High-riding nipples**VERY difficult to treat: a) horizontal wedge excision along IMF, b) direct repositioning NAC, c) implant placement to project nipple better, free nipple graft
  • Nipple loss: nipple sharing, local flaps, tattooing, skin grafts
  • Asymmetry: liposuction, re-reduction
  • Breast loss (partial or total): treat as breast reconstruction
  • Fat necrosis: FNA to r/o CA, observation, excisional biopsy
  • Dog ears: revision, liposuction, wait 1 yr
  • Postop hematoma: NAC in danger 2o direct pedicle pressure, vasoconstriction due to inflammatory mediators, direct toxic effects of blood byproducts
  • Scar revisions: wait 1 year
  • NAC malposition/ pseudoptosis: move nipple or breast, wait 1 yr (Ok to do inf wedge resection or BBA thru IMF for pseudoptosis thru prior inf pedicle BBR if >1yr)
  • BBR and NAC sensation: according to many studies <400 g reductions can expect almost 100% sensation – if lost returns in 2 to 12 months on average
  • BBR and lactation:~60-70% able to breastfeed postop

Q

briefly discuss approach to revision BBR

A

·Risks of all complications increased in revision reductions (wound healing, fat necrosis, nipple necrosis, infection).

oABSOLUTELY NOT in a smoker.Patient MUST accept these risks and ↑ potential for nipple graft

·find out initial technique, follow the same pedicle

·If 1⁰ pedicle unknown or in doubt à use free nipple graft vs. inferior pole wedge (if NAC position good) or vertical pattern with superior pedicle (Lista 2011)

·BROWN: if Wise pattern incision, stick to the same and use an inferior pedicle (this is what was most likely used – just keep broader base), but don’t cut the keyhole until the end

·Okay to do BBA thru IMF or PA incisions post BBR or revisions requiring transection of prior inf pedicle as long as not also repositioning/mobilizing NAC at same time

17
Q

what to do if permanent path report shows occult invasive malignancy in specimen

A
  • Incidental finding of breast cancer in BBR specimen: Rare 0.16-1%, Should be followed by: thorough workup, oncologic consultation and Rx (likely imaging, complete mastectomy)
18
Q

what do you do if you come across a suspicious lesion in breast DURING breast reduction?

A
  • Intraoperative suspicious mass during BBR
    • Intraoperative frozen sections
    • Intraoperative Gen Sx consultation (*consider only doing if frozen section comes back malignant)
    • If mass
      • Benign àclip, excise + no further treatment required
      • Malignant à entire mass excised, biopsy site marked (staples or clips), breast closed/ case terminated (to obtain closure – will likely need to complete resection but do as minimal as possible to close breast; if contralateral breast has not been cut yet – then DO NOT perform; if it has been cut e.g. simultaneous resection, then complete & close); postop formal workup (staging, oncologic consultation)
      • If on pedicle: don’t excise mass, mark with clips, close breast (if have consent and haven’t cut out mosque yet e.g. in Mahoney’s technique, then can covert to free nipple graft and excise mass)
19
Q

describe considerations for BBR in adolescent pt

A
  • Hormone induced occurrence
  • Virginal hypertrophy
  • Difficulty breast feeding in the future
  • Emotional & physiological maturity
  • Scars
  • Interference with mammography
  • Management: Counseling & Breast feeding_,_ Discussion of scars and possible recurrence in great length; aim to wait until breast maturity if possible (done growing x ~ 12 mos)
20
Q

discuss management of intra-operative dusky nipples/NAC

A
  • Initial steps: check systemic issues first (hypo/hypertension, hypothermia, u/o, O2 sat), release sutures, check for kinking of pedicle, hematoma warm saline soaks, give time
  • If nipple remains venous congested
    • McKissock or have not yet cut out mosque – can salvage with free nipple graft (need consent)
    • If pedicle cut already – need to decide if NAC has chance of surviving or not
    • no change: take NAC off pedicle as graft & bank in groin (make incision parallel to inguinal fold, elevate skin flaps, & bury NAC, close skin over top), also need to debride pedicle back to bleeding tissue. Replace NAC when breast fully healed (months)
    • ? salvageable: admit pt, pack open breast or loosely tack, put on Abx, warm saline and/or hep soaks, leeching, maintain hydration/BP/Temp, decide in 2-3 days if survived (yes – return to OR to close BBR; if no – must discard NAC & plan for delayed NAC recon & also debride pedicle)
  • **NB – arterial insufficiency to NAC is rare. Usually venous
21
Q

What is the purpose of mastopexy

A
  1. Elevate the NAC & breast parenchyma
  2. Reduce the skin envelope
22
Q

Describe the pathophysiology and risk factors for breast ptosis

A
  • Breast ptosis results from a combination of factors such as:
    • skin: laxity, reduced recoil, relative excess
    • parenchyma: involution, maldistribution, atrophy, fibrolipomatous change
    • fibrous & ligamentous breast tissue (investing breast fascia, cooper’s ligaments): laxity, reduced recoil
  • RFs/etiologic factors:
    • age
    • gravity
    • pregnancy, lactation
    • menopause
    • weight fluctuations
    • genetic predisposition
    • genetic or congenital anomalies
23
Q

How do you classify breast ptosis?

A
  • Regnault classification
  • Grade 1: Nipple at or within 1cm of IMF
  • Grade 2: Nipple below IMF, not at most inferiorly projection part of breast (~ 1-3cm below IMF)
  • Grade 3 ptosis: Nipple below the IMF, sitting on the most inferiorly projecting part of breast (> 3cm below IMF)
  • Pseudoptosis: the Nipple is above the IMF but the majority of breast parenchyma is below the IMF
24
Q

What factors do you consider when choosing an operation for breast ptosis?

A
  1. Procedures to address the amount of NAC ptosis (grade 1-3)
  2. Procedures to address the amount of excess skin (mild/mod/severe)
  3. Procedures to address the quantity and distribution of parenchymal (sufficient, insufficent, excess)
  4. Scars the patient is willing to accept
  5. Generally, amount of NAC ptosis and amount of skin excess are similar, and the chosen operation will address both components to a similar extent
25
Q

What are teh goals of mastopexy?

A
  1. Restore firm, youthful, durable breast appearance
  2. Elevate the NAC
  3. Tighten the skin envelope
  4. Reshape the parenchyma
  5. Maintain vascularity and sensation to NAC
  6. Minimize scar burden
26
Q

Describe how you will choose an operation for primary mastopexy

A
  1. To determine the incisions:
    1. Assess amount of NAC ptosis and skin excess
      1. Mild ptosis / excess: peri-areolar/concentric/eccentric
        1. Consider implant only if insufficient parenchyma
      2. Moderate ptosis / excess: Circumvertical, short vertical scar
        1. Consider inverted T if relative SKIN excess vs. ptosis
      3. Severe ptosis / excess: Inverted T
  2. To determine the approach to parenchyma
    1. Parenchyma sufficient
      1. skin redraping over parenchyma
      2. parenchymal redistribution & resuspension
    2. Parenchyma insufficient:
      1. Augment alone
      2. Mastopexy w/ augment
    3. Parenchyma excess
      1. Choose reduction mammoplasty instead of mastopexy
27
Q

List the advantages and disadvantages of periareolar incisions for mastopexy (or augment)

A
  • Advantages:
