The Pull-Through Technique — Minimal Scar, Careful Selection

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. Typically suited to Simon Grade I–IIa cases with mixed glandular-fatty composition where the gland is not too dense. The aim: a flatter chest contour without a periareolar scar — only 3–4 mm puncture sites, which typically fade within months. Individual results vary.

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 allows gland removal without a periareolar scar. Whether you are one of those patients is decided by examination — see liposuction vs. gland excision for how tissue type is assessed, and the Simon classification for grading.

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.

Outcomes & recovery

Compared with classical periareolar excision:

The recovery stages themselves — compression, swelling, return to travel — follow the same course as other gynecomastia procedures and are described in the recovery protocol, the week-by-week recovery guide and the compression vest guide.

When the plan changes in theatre: conversion to open excision

A pull-through is planned on the basis of examination, but the true density of a gland is only fully known once it is being mobilised. If the gland proves too dense or too adherent to deliver through the 4 mm port, forcing it risks an extended port and a visible scar — and leaving it behind risks early recurrence. The safer course is to convert to formal excision through a periareolar incision, the approach described in liposuction vs. gland excision.

For this reason, the possibility of conversion is part of the consent discussion for a pull-through. It is raised before surgery so that a periareolar scar, if it becomes necessary, is an expected outcome rather than a surprise. The aim is complete gland removal; the smallest possible scar comes second.

Risks to discuss before choosing a pull-through

No surgery is risk-free. A smaller incision does not change the main risks of gynecomastia surgery, which are discussed individually before any decision:

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 generally 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 typically fade within months and are usually difficult to see once mature, although healing varies between individuals.
