Surgical correction of breast inferior pole hypoplasia

Abstracts

INTRODUÇÃO: As mamas com hipoplasia de polo inferior apresentam aspecto desarmônico, com o sulco inframamário alto, predominância de volume glandular nos quadrantes superiores, e, consequentemente, direcionamento inferior do complexo areolopapilar. É meta desejável, nesses casos, a correção da forma desarmônica das mamas, bem como de eventuais assimetrias, com cicatrizes mínimas ou inconspícuas. O objetivo deste trabalho é apresentar técnica cirúrgica para correção de hipoplasia de polo inferior da mama. MÉTODO: A técnica cirúrgica utilizou retalho interno rodado para reconfigurar a mama e reposicionar o sulco inframamário, tendo como vias de acesso cirúrgico tão somente as cicatrizes por onde se colocam as próteses. RESULTADOS: A técnica descrita foi utilizada em 4 pacientes com hipoplasia de polo inferior de mama, com idades variando entre 19 anos e 27 anos. Os resultados demonstram que a correção da deformidade mamária foi alcançada adequadamente, bem como o reposicionamento do sulco inframamário, sem provocar irregularidades no contorno inferior da mama. CONCLUSÕES: A técnica proposta é uma alternativa adequada para o tratamento de casos selecionados de deformidade mamária com hipoplasia de polo inferior.

ABSTRACT

BACKGROUND: Breasts with inferior pole hypoplasia have a disharmonious appearance owing to a high inframammary fold and the prevalence of glandular volume in the upper quadrants that results in a lower inclination of the nipple-areola complex. In these patients, the goal is to correct the disharmonious shape of their breasts and possible asymmetries while causing minimal or inconspicuous scars. The aim of this study was to present a surgical technique to correct breast inferior pole hypoplasia.

METHODS: The surgical technique involved a rotated internal flap to reshape the breast and relocate the inframammary fold, a result achieved using only the scores where the implants would be positioned as surgical access routes.

RESULTS: The procedure described here was used in four patients aged 19-27 years with breast inferior pole hypoplasia. The results demonstrate that the correction of breast deformities was properly achieved, and the inframammary fold was repositioned without any irregularities in the inferior breast contour.

CONCLUSIONS: The technique proposed here is a suitable alternative for the treatment of selected cases of breast deformities with hypoplasia of the inferior pole.

INTRODUCTION

Breasts with inferior pole hypoplasia have a disharmonious appearance due to a high inframammary fold and the prevalence of glandular volume in the upper quadrants that results in a lower inclination of the nipple-areola complex (NAC)^1-6.

Von Heimburg et al.² classified deformities of the base of the breast into four different types:

• Type I - only the lower-medial quadrant of the breast is deficient;

• Type II - the presence of deficiencies in both inferior quadrants of the breast but no skin deficiency within the subareolar region;

• Type III - deficiencies in both inferior quadrants of the breast and one or more subareolar skin deficiencies; and

• Type IV - deficiencies within all four quadrants of the breast (tuberous breast).

Breasts presenting with inferior pole hypoplasia, regardless of von Heimburg classification types I, II, or III, are not tuberous, although they share several treatment difficulties. Moreover, patients with deformities of the base of the breast often exhibit mammary asymmetry as well, which renders the treatment even more complex.

The available methods for the treatment of breast inferior pole hypoplasia typically include mastopexia, which implies the use of implants and an extensive scar burden, and periareolar, associated with a lower vertical or "inverted T" type³. In these cases, the goal is to correct the disharmonious shape of the breasts and the possible asymmetries using minimal or inconspicuous scars. Taking this into account, some patients may benefit from techniques that use rotated internal flaps to reshape the breast and reposition the inframammary fold, a result achieved using only the scars where the implants would then be positioned as routes for surgical access as described in this case series.

METHODS

This study presents a series of four patients who underwent correction of breast inferior pole hypoplasia between 2010 and 2011. The patients underwent the following:

• Design and planning of the incisions - with the patient standing, an ideal inframammary fold was delineated, and sometimes, the fold was delineated to > 5 cm below the pre-existing inframammary fold. During the procedure, the incision along the ideal inframammary fold had sufficient extension. In the cases reported in this study, we chose incisions approximately 6 cm long;

• Dissection - beginning in the subglandular plane and continuing until above the NAC projection. In the upper portion of the mammary gland, a breast tissue flap was prepared (Figure 1A) to be positioned with the inferior base parallel to the skin and was then rotated 180º inferiorly (Figure 1B);

• Fixation of the flap - the upper extremity of the flap to the upper edge of the surgical wound was sutured with 3-0 monofilament nylon threads. This promotes filling of the inferior breast pole and pushing of the skin from the inside to the outside to cause disappearance of the pre-existing inframammary fold (Figure 1C). This step also ensures that, after surgery, the new inframammary fold would be positioned adjacent to the surgical wound;

• Double plane dissection and implant insertion - the plane below the pectoral muscle was dissected for breast implant insertion according to the double plane procedure. Subglandular dissection was vertically extensive owing to preparation of the flap, and it extended above the NAC. For this reason, it was considered necessary to re-suture the edge of the pectoral muscle to the breast using 3-0 monocryl threads prior to implant insertion (Figure 1D); and

• Closing - suturing by planes using 3-0 monocryl threads was performed, and the skin was closed using intradermal sutures.

RESULTS

The procedure described here was used in four patients aged 19-27 years with breast inferior pole hypoplasia. In all cases, we used texture-coated, cohesive, and high-profile silicone implants with volumes of 225-325 cc.

No complications were observed in the postoperative period. The longer followed up was of 2 years.

Figures 2 to 5 illustrate the results obtained in the four cases. The breast deformities were corrected, and the inframammary fold was appropriately repositioned without any irregularities in the inferior breast contour.

DISCUSSION

The procedure used in this case series closely resembled the technique described by Oroz e al.¹ in 2005 in which internal breast flaps were used to reconstitute the volume of the inferior breast pole and reposition the inframammary fold. The flaps were dissected starting from the same incision through which the implants were inserted. This is the main (or only) difference between the procedure described by Oroz et al.¹ and the technique used in this study.

The procedure described in the study by Oroz et al.¹ used a lower periareolar incision, whereas the route for surgical access in this series was through the inframammary fold. Otherwise, the approach within the breast and the dissection of the flap are identical.

The procedure described herein is an option for the treatment of breast inferior pole hypoplasia, as scars are significantly reduced compared to those of conventional mastopexy. Moreover, it is possible to correct deformities, increase breast volume, and safely achieve a new and proper inframammary fold position without causing any irregularities in the inferior breast contour.

The cases presented here evolved positively. The patients were satisfied with the result, and thus far, no complications have been observed in the postoperative period.

CONCLUSIONS

Despite the small sample size and limited follow-up period, the results obtained here suggest that the proposed procedure is a suitable alternative for the treatment of selected cases of breast deformities and inferior pole hypoplasia.
