Aesthetic reconstruction of the tuberous breast deformity

The tuberous breast deformity is a rare entity affecting young women bilaterally or unilaterally. The deformity is characterized by a constricting ring at the base of the breast, which leads to deficient horizontal and vertical development of the breast with or without herniation of the breast parenchyma toward the nipple-areola complex and areola enlargement. Several methods have been put forward to correct the deformity, but most of these fail to address the issue of the constricting ring and subsequently yield results that are not aesthetically satisfactory. A new approach to the treatment of the deformity is presented, which consists of a periareolar approach and rearrangement of the inferior part of the breast parenchyma by division of the constricting ring, thus creating two breast pillars. These pillars are allowed to redrape, and in cases of volume deficiency, a silicone breast implant is placed in a subglandular pocket. The procedure is completed by a donut-type excision to address the size of the nipple-areola complex. The technique has used on 11 patients (21 breasts) with excellent aesthetic results.     

Chest-wall deformity following soft-tissue expansion for breast reconstruction

We have presented a case in which the presumed pressure effects of tissue expansion caused multiple nondisplaced rib fractures of the anterior thorax in a patient undergoing breast reconstruction. Although the deformity was severe, a satisfactory cosmetic result was obtained and there have been no clinically significant sequelae during a 1-year follow-up period. The degree of bony deformation was most likely enhanced by the combination of this patient's severe osteoporosis, chronic steroid use, and peripheral vascular disease. The fragility and ease of fracture in the bones of osteoporotic postmenopausal females and the long-term effects of steroids on tissues is well known. We believe this observation to be important, since many reconstructed patients are postmenopausal and have variable degrees of osteoporosis. Many undergo adjuvant chemotherapy with steroids and antihormonal agents, and this group of women may therefore be at a greater risk for the occurrence of pressure deformities. The incidence and long-term significance of such deformities are not known. The reconstructive surgeon should be alert to the possibility of this phenomenon occurring as a result of tissue expansion in the patient with severe osteoporosis, peripheral vascular disease, or chronic steroid use.     

Chest-wall deformity after tissue expansion for breast reconstruction

A prospective longitudinal study of chest-wall deformity after tissue expansion for breast reconstruction was performed in 19 women. CT imaging was a sensitive method for detecting occult deformity. Using a semiquantitative scale for measuring deformity, all patients and 94 percent of expanders had some thoracic abnormality after tissue expansion. Rib and chest-wall contour changes were observed under 81 and 68 percent of the expanders, respectively. Routine chest roentgenograms were not a sensitive method for evaluating these deformities. The magnitude of deformity after unilateral expansion was not significantly different from that after bilateral expansion. Linear regression analysis indicated that early periprosthetic capsular contracture was negatively correlated with chest wall deformity. Only one patient experienced a clinically noticeable complication from chest compression--transient postexpansion exertional dyspnea. After removing the expanders and placing permanent implants along with capsulotomy, the mean deformity index decreased by 57 percent after 10.5 months median follow-up, which was highly significant (p less than 0.001). Our findings suggest that chest-wall deformity is a common occurrence after tissue expansion in patients undergoing breast reconstruction and is usually of minor clinical significance.     

Breast reconstruction using an inflatable breast implant with detachable reservoir

An inflatable breast implant having a detachable filling reservoir is described. Once in position, the implant can be filled under controlled conditions postoperatively. The implant functions either as a tissue expander or as a delayed-filling implant in the initial stages of the procedure. Once the desired breast size is achieved, the reservoir is removed, leaving the filled implant in position. This implant has been used successfully in various types of breast reconstructive procedures, including both primary and secondary reconstruction following modified mastectomy, immediate reconstruction following subcutaneous mastectomy, secondary reconstruction following radical mastectomy combined with the latissimus dorsi flap, and following the removal of silicone gel implants with associated capsular contracture. A total of 23 patients, representing 34 breasts, are reported on. The results have been encouraging over a period of 20 months of follow-up.
