Gynecomastia, or abnormal breast tissue enlargement in men. The aim of treatment is restoration of a normal male chest contour while minimizing the evidence of surgery and protecting the nipple areolar complex. Although excisional techniques have traditionally been the accepted standard, liposuction has now become established as the prime surgical modality either alone or in combination with more invasive methods. 

Basic science 

Gynecomastia is thought to primarily result from an increased estrogen to androgen ratio since estrogens stimulate breast tissue while androgens antagonize its effects. This hormonal imbalance may therefore arise from an absolute or relative excess of estrogens, or an absolute decrease of androgen levels or their action. 

Etiologically gynecomastia can be physiological or pathological in nature. The former may occur during three different age groups. 

A thorough history is important to determine the underlying cause of gynecomastia  and rule out breast cancer and other tumors. On the other hand, it should be noted that around 25% of gynecomastia cases may be idiopathic. Salient points include patient age, onset and duration of breast enlargement, symp-toms of associated pain, recent weight change, and a systems review with particular attention to possible endocrine and liver abnormalities. Medications and recreational drug use need to ascertained as they may cause 10–20% of gynecomastia cases. 

On physical examination, gynecomastia is usually bilateral and felt as glandular tissue under the nipple areolar complex and extends to a variable size in all directions. It needs to be differentiated from pseudogy-necomastia or lipomastia, which is adipose tissue hypertrophy without glandular proliferation. physical examination should include assessment of secondary sexual development and the thyroid, as well as looking for signs of chronic kidney or liver disease. When examining the genitalia, it is also important to look for any testicular masses or atrophy. Liver enlargement may sometimes be encountered. There  is  no  increased  risk  of  breast  cancer  in  patients with  gynecomastia  when  compared  with  the  unaffected male  population.s  The  exception  is  patients  with  Klinefelter syndrome.  These  patients  have  an  approximately  60  times increased  risk  of breast cancer 

Bio-chemical assessment includes tests for liver, kidney,  and thyroid function; and serum levels of testosterone, prolactin, follicle-stimulating hormone, and luteinizing hormone. Additional tests may be necessary in cases of recent or symptomatic gynecomastia to rule out tumors.2 For example, serum levels of estrogens, human chori-onic gonadotrophin (hCG), dehydroepiandrosterone (DHEA), and urinary 17-ketosteroids. 

Simon et al Classification

2b and 3 types need skin excision ( in same sitting or 4-6 months later). 

Letterman  and  Schuster‘  created  a  classification  system based  on  the type  of correction:  1:  intra-areolar  incision  with no  excess  skin;  2:  intra-areolar  incision  with  mild  redundancy corrected  with  excision  of skin  through  a  superior periareolar scar;  and  3:  excision  of  chest  skin  with  or  without  shifting the  nipple. 

Rohrich  et  al.  in  a  paper  discussing  the  utility  of  ultrasound-assisted  liposuction  in  the  treatment  of  gynecomastia,  developed  the  following  classification:  grade  I:  minimal hypertrophy  (<250  g  of  breast  tissue)  without  ptosis;  grade 2:  moderate  hypertrophy  (250  to  500  g  of breast tissue)  without ptosis;  grade  3:  severe  hypertrophy  (>500  g  breast tissue) with  grade  I  ptosis;  grade  IV:  severe  hypertrophy  with  grade 2 or3  ptosis. 

Types of gynecomastia  

Three  types  of  gynecomastia  have  been  described:  florid, fibrous,  and  intermediate. The  florid  type  is  characterized by  an  increase  in  ductal  tissue  and  vascularity.  A  minimal amount  of fat  is  mixed  with  the  ductal  tissue.  The  fibrous type  has  more  stromal  fibrosis  with  few  ducts.  The  intermediate  type  is  a  mixture  of  the  two.  The  type  of  gynecomatia  is  usually  related  to  the  duration  of  the  disorder.  Florid gynecomastia  is  usually  seen when  the  breast enlargement  is of new  onset  within  4  months.  The  fibrous  type  is  found  in cases  where  gynecomastia  has  been  present  for  more  than 1  year.  The  intermediate  type  is  thought  to  be  a  progression  from  florid  to  fibrous  and  is  usually  seen  from  4  to 12 months. 

Medical management  

Most cases of gynecomastia do not require treatment  as they are benign and self-limiting. Weight loss should be recommended for male patients with pseu-dogynecomastia in the first instance. Medical therapies essentially focus on correcting the imbalance of androgens and estrogens. furthermore, medications are probably most effective during the active, proliferative phase of gynecomastia. In patients with long-standing gynecomastia of over 1 year, medical treatment is often ineffective as the breast glandular tissue progresses to irreversible dense fibrosis and hya-linization. Such cases should be considered for surgical treatment. When treatment is indicated, most patients do not need a trial of medical therapies and are best managed with surgery, which is the mainstay modality. 

Surgical management  

Well-established  surgical  techniques  for  gynecomastia treatment  include  various  forms  of  liposuction,  open glandular  excision,  skin  reduction,  and  combinations  of these. 

General Anesthesia as day care except in patients where excision of skin is planned. All  patients  receive  perioperative  broad-spectrum  antibiotic  prophylaxis  at  general anesthetic  induction. Patients  are  marked  preoperatively  in  the  upright sitting  position  highlighting  the  inframammary  fold, breast  boundaries,  planned  stab-incision  sites,  and  concentric  topography-type  marks  centered  on  the  most prominent  portion  of  the  breast. Infiltration with superwet technique done (300 mg per litre lignocaine). 


Liposuction of Breast is done however residual  subareolar  tissue  is  a  frequently  encountered complication  with  this  technique. SAL  is  not  suitable  for severe  cases  or  in  breasts  with  primarily  fibrous  tissue. It  can  be  effective in  soft  breasts  even  if  large,  but  good  skin  quality  is important  for  later  contraction  and  avoiding  the  need for  skin  resection.  Liposuction  allows  the  achievement of  better  breast  contours  with  minimal  scarring. Cross-tunnel  suctioning  for  larger breasts,  ptotic  breasts,  and  those  with  excess  skin  or well-defined  inframammary  folds  makes  SAL  more effective. The  laterally  placed  incision  in  the  inframammary  fold allows  better  access  for  the  liposuction  to  the  whole breast  laterally  and  medially. Cross-tunnel  suctioning  for  larger breasts,  ptotic  breasts,  and  those  with  excess  skin  or well-defined  inframammary  folds  makes  SAL  more effective.  Such  extensive  cross-suctioning  enables  more consistent  contraction  of  the  skin  and  allows  it  to  redrape with  less  waviness  and  irregularity. A  4.6  mm  or  5.2  mm  Mercedes  cannula  is  used  for  the  initial  suction  employing the  palm  down  and  pinch  techniques. Finer refinement by 3 mm or 3.7 mm Mercedes cannula. Once a  satisfactory  contour  is  obtained,  the  surrounding  fat is  feathered  to  avoid  a  noticeable  saucer  deformity,  and any  well-defined  inframammary  fold  as  determined preoperatively  is  deliberately  disrupted  in  order  to avoid  the  gynecoid  (female)  contour  of  the  breast. When  liposuction  is  unsuccessful  at  removing  all  of  the tissue  required  to  achieve  a  good  result,  the  pull-through technique  is  added.  In  this  technique,  either  the  lateral  or periareolar  incision  is  opened  slightly  (about  1.5  em)  and  the residual  tissue  is  grasped.  The tissue  is  pulled  out through  the wound and removed  with scissors  or  electrocautery 

UAL is more effective for firmer Breast tissue . By  emulsifying  breast  fat,  it is  particularly  useful  for  addressing  dense,  fibrous gynecomastia.  It  has  also  been  suggested  that UAL  results  in  less  postoperative  bruising,  a  smoother breast  contour,  better  postoperative  skin  contraction, and  less  surgeon  fatigue. The  well  described  UAL  endpoints73  are determined  by  loss  of  tissue  resistance,  aspirate  volume, blood-tinged  appearance  of  the  aspirate,  and  planned treatment  time. UAL induces skin contraction also. 

Different Canula types

Open approach  

Liposuction  is frequently  not  effective  for  very  glandular  tissue,  small discrete  breast  buds,  and  body  builders  as  the  latter have  large  amounts  of  glandular  tissue  with  little  fat. Open  excision  via  an  inferior  periareolar  approach11 is  the  traditional  approach.  Various  other  incisions have  been  described  such  as  circumareolar,  periareolar, transareolar, circumepithelial. The  liposuction  serves  a number  of  purposes  such  as  pretunneling  to  facilitate resection,  reducing  bleeding  and  bruising,  and  partially  breaking  down  the  breast  tissue.  After  liposuction  the  tissue  can  be  resected  via  a  number  of  access  incisions. At  least  a  1  cm  disc  of  breast  tissue is  left  under  the  areola  to  prevent  a  depression  of  the nipple  areolar  complex. Excess skin may be reduced in same or different sitting according to the acceptance of scar by the patient. 

Skin  reduction There  are  a  number  of  procedures  used  to  reduce excess  skin  in  gynecomastia. In  patients  with  obvious  skin  excess  or  very  large breasts,  skin  reduction  techniques  should  also  be planned  usually  at  the  same  time  as  the  open  excision of  the  breast  tissue  or  as  a  second  stage,  a  minimum  of 4–6  months  later.  There  is,  however,  no  consensus  on when  and  how  to  undertake  skin  resection. 

Post operative  

Drains  are  not  routinely  used,  except  for  large  resections or  when  skin  reduction  is  performed,  such  as  in  post massive  weight  loss  patients.
