The Pectoralis Peg with Bowtie Nipple-Areolar Reconstruction
An image article
by Edward Knowlton MD


Incision for a skin preservation mastectomy

Careful sharp dissection of the breast skin during mastectomy

The defect created from a skin-sparing mastectomy

During a skin-sparing mastectomy

Immediately after a mastectomy with insertion of a breast expander

Two months after a mastectomy with complete inflation of a breast expander

Growth of new vessels from the pectoralis major

Neovascularization of the remaining breast skin

The relationship of a skin-sparing mastectomy scar with the Bowtie incision

The relationship of a skin-sparing mastectomy scar and the Bowtie incision within the neovascular territory of the Pectoralis Peg

Small neovascular perforators grow perpendicular to the skin surface

Creation of the nipple-areolar complex will cover a nondisplaced mastectomy scar

A rectangular shaped Bowtie flap will result in a flat areolar contour

The width of the Bowtie flap determines the height of the nipple

A divergent shaped Bowtie flap will result in a conical areolar contour

A divergent shaped Bowtie flap that is curved

The left breast is fully expanded for the second stage Pectoralis peg with Bowtie nipple-areolar reconstruction

The Bowtie flap raised full thickness with a central pedicle of pectoralis and scar capsule

The semicircular flap is advanced to the top of the nipple

With the exception of irradiated skin, the circulation of the Bowtie flap is excellent

The removal of the expander and the replacement with the permanent implant is performed through the Bowtie incision

Adequate exposure is obtained through the Bowtie incision for modification of the implant pocket

Insertion of the permanent implant through the Bowtie incision

The permanent saline implant is inflated with a closed system

Preliminary closure of the Bowtie incision.
Patient is then placed in a sitting position to judge symmetry

The nipple is created with the Bowtie flap

Closure of the Bowtie incision after achievement of volume symmetry

A 3.8 cm or 4.2 cm circular template is used to inscribe the areolar border

The inscribed areolar border. Closure of the bowtie incision has created a conical shaped areolar contour

The inscribed areolar border is incised

The adjacent breast skin is undermined

Irregular skin margins are conservatively excised

Purse string suture is inserted into breast skin margin

Purse string suture is drawn around the nipple-areolar complex

Closure and projection of the nipple-areola is achieved with the purse string suture

Nipple-areolar projection is achieved without compromising flap perfusion

Breast expanded with a standard mastectomy scar

The neovasularization of the Pectoralis Peg with a standard mastectomy scar

The relationship of a standard mastectomy scar with the Bowtie incision within the Neovascular territory of the Pectoralis Peg

The Bowtie Flap Raised full thickness with an expanded central pedicle of Pectoralis and scar capsule

A typical deformity from a modified radical mastectomy with skin resection

After the first stage with insertion of the expander and repositioning of the left breast. The right breast has been fully expanded

Three months after completion of the right breast reconstruction. A Pectoralis Peg with Bowtie nipple-areolar reconstruction was performed
