The Pull-Through Technique — Minimal Scar, Maximum Removal
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
- Marking and anaesthesia. The patient is marked standing. General anaesthesia is typical; local + sedation is possible in lean patients with small resections
- Tumescent infiltration. Lidocaine-epinephrine solution is infiltrated into the entire operative field for haemostasis and hydrodissection
- 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
- 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
- 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
- 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
- Closure. The 4 mm port is closed with a single subcuticular suture. No visible periareolar scar
Ideal candidates
- Simon Grade I–IIa with mixed glandular-fatty composition
- Moderate gland size — typically 15–40 g per side
- Semi-fibrous gland, not dense or heavily calcified
- Young, elastic skin that will retract without surgical tightening
- Younger patients (under 40) tend to respond best due to skin elasticity
When the pull-through is NOT the right choice
- Dense fibrous gland that cannot be safely mobilised — requires direct excision
- Large gland volumes (>50–60 g) that would require enlarging the port defeating the purpose
- Simon Grade IIb with skin laxity — even a perfect gland removal won't produce a good result without addressing skin
- Revision cases where scar tissue from prior surgery prevents clean mobilisation
- Suspected calcification on examination or imaging
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.
Technical pitfalls
| Pitfall | Consequence | Avoidance |
|---|---|---|
| Over-aggressive retroareolar liposuction | Crater deformity | Preserve 5–8 mm retroareolar disc |
| Incomplete gland removal | Early recurrence | Finger palpation check at end of procedure |
| Forced pull-through of dense gland | Extended port, visible scar | Convert to open if required |
| Nipple devascularisation | Partial necrosis | Preserve subdermal vascular plexus at areola |
| Ignoring skin laxity | Underwhelming contour | Re-grade to IIb if needed, change plan |
Outcomes & recovery
Compared with classical periareolar excision:
- Operative time: 45–90 min (vs 90–120 min)
- Return to desk work: 3–5 days (vs 5–7 days)
- Return to full upper-body training: same — 6 weeks
- Scar: 4 mm puncture (vs ≈5 cm periareolar)
- Patient satisfaction: very high in appropriate candidates; disappointing if technique was forced in wrong anatomy

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.
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.
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.
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.
