Inferior Pedicle Technique in Breast Reduction: Practical Steps



Inferior Pedicle Technique in Breast Reduction: Practical Steps


Saul Hoffman



In 1975, Ribeiro described a new technique for reduction mammaplasty in which the nipple is based on an inferior dermal flap (1). Two years later, Robbins (2) and then Courtiss and Goldwyn (3) reported a similar procedure. Soon thereafter, Reich (4), then Georgiade and et al. (5), published their experience with the same method. Since then, the inferior pedicle technique has become one of the most common methods of breast reduction in use today. In 1987 a survey of the members of the American Society of Plastic and Reconstructive Surgery found that 36% preferred this method (6). This may have changed with the introduction of newer techniques, such as the short-scar technique of Marchac (7), the Lejour vertical mammaplasty (8), and the round block operation of Benelli (9).

The operation is versatile and safe and can be used for most cases of breast hypertrophy. There are virtually no contraindications, except perhaps in cases of gigantomastia. The pedicle in these cases will be large, and adequate reduction may not be possible. Free nipple grafting for this group of patients is preferred. An inferior flap consisting of dermis and glandular tissue with free nipple grafting will prevent overresection and maintain an aesthetic contour.

The term “inferior pedicle” is descriptive but misleading because it implies that the blood supply comes through an inferiorly based pedicle. A more accurate description, as given by Labanter et al. (10), is the inferior segment technique. The main blood supply of the breast is from the lateral thoracic, internal mammary, and intercostal vessels. It is therefore possible to resect the inferior segment without compromising the blood supply (Fig. 95.1). A procedure using this principle was described by Hester et al. (11) in an operation using a central breast pedicle. An understanding of the anatomy is essential if one is to maintain circulation and sensation to the nipple. A layer of tissue over the fascia must be preserved to protect the vessels as they enter the pedicle. The pedicle can be sculpted to the appropriate size and the flaps thinned when further reduction is required. (Patients often complain of lateral fullness after a reduction mammaplasty if adequate resection has not been performed in this area.) On the other hand, care must be taken to preserve enough tissue medially for adequate cleavage. Before closure, the pedicles and the thickness of the flaps should be compared in order to obtain the best possible symmetry. Suction-assisted lipectomy can be added for further refinement.


Preoperative Planning

Precise planning is essential if one is to achieve a good result. Patients are now being admitted on the day of surgery, so it is more efficient to mark them in the office within a few days before the operation. The markings are made in the routine fashion with a marking pen and reinforced with a sharpened applicator stick that is dipped into a 20% solution of silver nitrate. The silver nitrate leaves a brown stain on the skin that lasts for 7 to 10 days. The patient can shower preoperatively without disturbing the markings.

Marking is begun with the patient in the standing position. The vertical axis of each breast is marked (Fig. 95.2). This line extends through the nipple to the inframammary fold—in some patients the nipple is located medial or lateral to the vertical axis. Next the nipple position is determined by placing a finger in the inframammary fold and marking the anterior projection on the vertical axis (Fig. 95.3). This position is checked by measurement to the clavicle and to the midline and with the contralateral nipple to ensure symmetry. In large breasts, the nipple position may need to be lower or more medial in order to avoid positioning it too high or too lateral. The amount of skin to be resected is then determined by pinching the breast between the thumb and index finger (Fig. 95.4). These points are marked.

An inverted V-shaped incision is then outlined from the new nipple site to these two points. A distance of 7 cm is measured along the limbs of the inverted V from the apex (Fig. 95.5). The inframammary fold is marked and the medial and lateral skin excision outlined so that the upper and lower limbs are approximately the same length (Fig. 95.6). With experience, one will determine a range for these measurements. In order to keep the incision from extending too far medially and laterally, the lower incision can be moved above the fold onto the skin of the breast.
