The Pull-Through Technique — Minimal Scar, Maximum Removal

Key takeaway

The pull-through technique (Morselli, 1996) is a minimally invasive gynecomastia approach that combines liposuction with gland delivery through the same small port — avoiding the formal periareolar incision. Best suited to Simon Grade I–IIa cases with mixed glandular-fatty composition where the gland is not too dense. The result: a flat masculine chest with no visible periareolar scar, only 3–4 mm puncture sites that fade within months.

The pull-through technique is a minimally invasive approach to gynecomastia that removes the glandular component through the same small port used for liposuction — avoiding the classical inferior periareolar incision while still addressing the tissue that liposuction alone cannot reach. For selected Simon Grade I–IIa patients, it offers the best of both worlds: gland removal with no visible surgical scar.

Key principle: the pull-through technique is elegant and effective — but it is not universal. A gland that is too dense, too adherent, or too large cannot be safely delivered through a small port. Knowing when the pull-through is indicated and when it is not is the clinical skill; blindly attempting it in the wrong anatomy produces incomplete gland removal and recurrence.

How the technique works — step by step

  1. Marking and anaesthesia. The patient is marked standing. General anaesthesia is typical; local + sedation is possible in lean patients with small resections
  2. Tumescent infiltration. Lidocaine-epinephrine solution is infiltrated into the entire operative field for haemostasis and hydrodissection
  3. Aggressive subcutaneous liposuction. Using 3–4 mm cannulas through a single lateral or axillary 4 mm incision. The fat component is removed in full; the gland remains because it resists cannula action
  4. Gland mobilisation. A slightly more aggressive pass of liposuction around — but not through — the gland disrupts the surrounding adherent fat, leaving the gland semi-free in the cavity
  5. Pull-through. Through the same 4 mm port, a small Allis or tenaculum forceps is introduced, grasps the gland, and delivers it in one or several pieces without enlarging the incision. A dedicated "gynecomastia retractor" may be used
  6. Cavity verification. Finger palpation through the port confirms that no residual firm tissue remains. Any retained fragment is removed with further liposuction or additional forceps passes
  7. Closure. The 4 mm port is closed with a single subcuticular suture. No visible periareolar scar

Ideal candidates

When the pull-through is NOT the right choice

Advantages over classical periareolar excision

The classical approach involves a ≈5 cm periareolar arc incision, direct visualisation, and formal gland excision. It remains the gold standard for larger glands and Grade IIb cases. The pull-through's advantages over it, in appropriately selected patients: no visible scar, shorter operative time, faster recovery, less post-operative bruising, and often less swelling. Its disadvantages: reduced tactile control of resection margins and inability to handle very large or very dense tissue.

Frequently asked questions

What is the pull-through technique in gynecomastia surgery?

The pull-through technique is a minimally invasive approach in which the surgeon performs aggressive subcutaneous liposuction first, then grasps the remaining fibrous gland with forceps through the small liposuction port and delivers (pulls through) the gland without enlarging the incision. This avoids the formal periareolar scar of classical gland excision while still removing the glandular component.

Who invented the pull-through technique?

The pull-through technique was described by Morselli in 1996 as an evolution of standard gynecomastia liposuction. The technique has since been refined by multiple surgeons internationally. It is now a mainstream approach for Simon Grade I–IIa gynecomastia, especially in patients prioritising minimal scarring.

Can pull-through technique be used for all gynecomastia cases?

No. Pull-through is best suited to Simon Grade I–IIa with mixed glandular-fatty composition. It is less suitable for very dense fibrous glands (where the tissue cannot be effectively pulled through the small port), Simon Grade IIb–III with significant skin excess (which requires formal excision and skin tightening), and revision cases. The right technique depends on individual anatomy.

Is the scar smaller with pull-through than gland excision?

Yes — significantly. The pull-through technique uses only 3–4 mm puncture sites at the inframammary border or lateral chest, similar to liposuction-only. There is no periareolar incision and therefore no periareolar scar. The puncture sites fade within months and are essentially invisible at any reasonable distance.
