Implant-based breast augmentation through a hidden axillary (under-arm) incision, leaving no scar on the breast itself. The signature procedure of Umnagumo Plastic Surgery, refined over 25 years through the Tokyo Nagumo Clinic protocol.
Breast augmentation at Umnagumo Plastic Surgery is performed with implants (Mentor, Motiva, or Sebbin) selected to match the patient’s chest anatomy, soft-tissue thickness, and desired outcome. The trans-axillary approach — an incision hidden in the natural armpit fold — is the clinic’s signature technique and leaves no visible scar on the breast itself.
Implant size, profile, and placement plane are individually planned during consultation, taking into account the patient’s rib cage width, existing breast tissue, skin elasticity, and lifestyle. Where anatomy is suitable, the trans-axillary approach is preferred to preserve breast and nipple aesthetics.
A 3–4 cm incision is made within the natural axillary skin fold. The implant is placed in a sub-glandular, dual-plane, or sub-muscular pocket, selected based on the thickness of the patient’s soft tissue. The axillary scar typically settles into the natural folds and fades within 6–12 months.
Implant brand (Mentor, Motiva, Sebbin), profile (moderate, high, or extra-high), and base width are matched to the patient’s rib cage and breast footprint. The objective is a natural-looking result that is proportionate to the body, rather than a uniformly enlarged silhouette.
Most patients return to light daily activity within 2–3 days. Driving and desk work are typically resumed within one week. Vigorous exercise and arm-overhead movements are reintroduced gradually over 4–6 weeks.
In-clinic follow-up is scheduled at 1 week, 1 month, 3 months, 6 months, and 12 months. International patients can complete long-term follow-up by video consultation after the initial in-person visits, with annual ultrasound monitoring recommended thereafter.
Umnagumo Plastic Surgery uses Mentor (Allergan), Motiva, and Sebbin implants — all KFDA-approved. The choice depends on tissue thickness, desired feel, and lifestyle. A side-by-side implant comparison is reviewed during consultation.
No. The implant is introduced via an incision distant from the milk ducts and does not interrupt the gland or the nerve supply involved in lactation.
Primary breast augmentation typically takes 40–60 minutes under general anesthesia. Patients are discharged the same day after a recovery monitoring period.
Modern breast implants do not have a fixed expiration date but require periodic ultrasound monitoring (every 1–2 years). Replacement is only indicated if a complication or implant change is detected.
