Skin-sparing mastectomy with sentinel lymph node dissection: less is more.

Skin-sparing mastectomy is an emerging technique useful for patients with early-stage breast cancer who are not candidates for breast conservation surgery and are candidates for immediate plastic surgery reconstruction of the breast. Coupled with sentinel node surgery to assess lymph node status, the goal of this technique is to achieve maximal breast and axillary tissue conservation without compromising thorough tumor resection.

Modified autogenous latissimus breast reconstruction and the box top nipple.

During the past 3 years, the authors have been using the modified autogenous latissimus myocutaneous flap (MALF) for breast reconstruction in increasing numbers because of occasional patient and surgeon dissatisfaction with other methods of breast reconstruction. They have found this method to have unprecedented reliability, making it preferable to other forms of reconstruction in many patients. Considering the very low morbidity, the high patient satisfaction, and current economic factors, the authors are strong advocates of this form of reconstruction. A procedural outline proposed by McCraw and coworkers is followed, with some useful modifications. An elliptical transverse skin paddle is centered over the back fat roll. The area of the skin ellipse measures approximately 8 +/- 2 cm vertically and 30 +/- 5 cm transversely. After making the skin incision, a feathering technique is used in all directions through the fatty layer overlying the latissimus and in the tissue beyond the anteroposterior borders of the latissimus (not beyond 5 cm from the skin incision). By means of feathering, the shape of a breast mound can be created in the allowable tissue supported by the latissimus. A 180-degree rotation of the flap allows dependentvenous drainage and more bulk in the inferior outer quadrant, where it is needed. In the current series of 47 modified autogenous latissimus breast reconstructions, seromas were common. Other complications included one wound infection, one ulnar neuropraxia, and one fat necrosis. There were no flap necroses (partial or complete) or hematomas. The rarity of complications supports the use of this technique in selected patients. An innovative new technique for nipple reconstruction is also described. The "box top technique" of nipple reconstruction consists of four deepithelialized local flaps covered with a skin graft from the groin.

Mammographic determination of breast volume: comparing different methods.

OBJECTIVE: The purpose of this study was to compare the accuracy and reproducibility of different methods for calculating breast volume when using measurements made on mammograms. MATERIALS AND METHODS: The volumes of 32 breasts were determined by pathologic evaluation of mastectomy specimens. Two radiologists independently measured breast height and width on the preoperative craniocaudal mammograms and measured height, width, and width at half-height on mediolateral oblique mammograms. Compression thicknesses used on the craniocaudal and mediolateral oblique projections were recorded. Volume was then calculated using six different formulas. The accuracy of each method was determined and compared using bivariate and univariate linear regression analyses. Interobserver variability in measurement was also assessed. RESULTS: The most accurate method for calculating breast volume was the one that assumed a half-elliptic cylinder shape for the compressed breast in the craniocaudal projection. Measurements made on the craniocaudal view were more reproducible than those made on the mediolateral oblique view. CONCLUSION: Breast volume can be accurately and reproducibly determined on mammograms by making two measurements on the craniocaudal view and knowing the compression thickness. This information may be useful to plastic surgeons, investigators who study parenchymal patterns, and physicians who examine cancer patients being considered for breast conservation surgery.

Salvage of failed amputation about the hip in peripheral vascular disease by open wound care and nutritional support.

Five consecutive patients with wound and/or plastic surgical flap failure after hip disarticulation or amputation at the lesser trochanteric transfemoral level were treated with local tissue debridement, open wound management, culture-specific antibiotic therapy, and nutritional supplementation. All of the patients underwent amputation about the hip as a result of ischemic necrosis of the lower extremity. Four of the five patients were able to achieve wound healing by second intention. The fifth patient died 2 months after the surgery. None of the patients required revision surgery. One patient underwent split-thickness skin grafting to minimize the need for continued wound care. Local wound management combined with nutritional support and culture-specific antibiotic therapy is an acceptable alternative to major amputation stump revision in patients with potentially high morbidity who fail to heal after amputation about the hip.

A full nasal skin rotation flap for closure of soft-tissue defects in the lower one-third of the nose.

Large soft-tissue defects in the lower one-third of the nose challenge the reconstructive surgeon both technically and aesthetically. Many procedures have been described previously that close the wound with varying degrees of color and texture match. We present a modified nasal rotation flap that closes large soft-tissue defects of the lower one-third of the nose in a single stage with minimal donor-site morbidity and a pleasing aesthetic result.

Sonographic signs of breast implant rupture.

OBJECTIVE: This study evaluated sonography as a screening test for breast implant rupture and developed diagnostic criteria for implant rupture. SUBJECTS AND METHODS: Women contemplating implant removal were evaluated prospectively with sonography. Implants were classified as normal, indeterminate, or ruptured. Individual sonographic signs were analyzed for their statistic association with implant rupture. To measure the degree of interobserver variation, static images were evaluated by two different observers. RESULTS: Of 236 implants evaluated, surgical confirmation was available in 78, 22 of which were ruptured and 56, intact. Echogenic noise, multiple discontinuous parallel linear echoes, and echodense aggregates in the implant lumen were statistically associated with rupture. Based on sonographic findings, we classified 34 implants as intact (at surgery: 31 intact, 3 ruptured). We classified 19 as ruptured (at surgery: 11 ruptured, 8 intact). Of the 25 implants we classified as indeterminate, 17 were intact and 8 were ruptured at surgery. Therefore, sonography had a positive predictive value of 58%, a negative predictive value of 91%, a sensitivity of 50%, and a specificity of 55%. Receiver operating characteristic analysis suggests a learning curve effect and no significant interobserver variation. CONCLUSIONS: A normal sonographic result is highly predictive of an intact implant. Thus, sonography is useful in evaluating symptomatic women or women concerned about implant rupture. An indeterminate sonographic result suggests the need for further testing.

Functional outcome following traumatic upper limb amputation and prosthetic limb fitting.

Nineteen consecutive patients underwent traumatic upper limb amputation for nonreconstructible or replantible upper limb injury at a Level I trauma center over a 9-year-period. Eleven amputations were at the transradial level, five were transhumeral, and three were shoulder disarticulation. Eighteen patients underwent prosthetic limb fitting. Fifteen of the 18 initially underwent preparatory prosthetic limb fitting within 30 days following amputation with a body-powered, cable-driven prosthesis. Seventeen of the 18 achieved sufficient proficiency with their prostheses to allow them to return to work. Of these, 15 maintained daily functional prosthetic use of at least 8 hours daily at a followup examination of 12 to 110 months. Use of prosthetic limb following traumatic upper limb amputation carries a high probability for functional rehabilitation if limb fitting and prosthetic training are instituted as soon as the residual limb can tolerate the prosthetic socket as opposed to waiting for the residual limb to "mature".

Angiotensin-1-converting enzyme activity as index of pulmonary damage in thermal injury with or without smoke inhalation.

Serum angiotensin-converting enzyme (ACE) activity, plasma renin activity (PRA), and serum aldosterone levels were measured up to four weeks in a population of adults exposed to thermal injury, with or without concomitant exposure to smoke inhalation. In 10 patients, plasma levels of angiotensin-2 and ACE activity in bronchial lavage were also evaluated. Patients with severe burn injury had a significant decline of serum ACE activity while the concentrations of aldosterone and PRA were markedly elevated. Smoke inhalation seemed to counterbalance the decline of serum ACE activity, and, in the last group of patients, ACE concentrations were higher than those recorded in patients suffering only from cutaneous burn. The ACE activity was evidenced in bronchial lavage of patients exposed to smoke inhalation with the highest values present in the first day after the injury. The same patients had also very elevated levels of plasma angiotensin 2. In conclusion, serum ACE activity decreases in burn patients according to the severity of the cutaneous burn; smoke inhalation influences serum levels of the enzyme with concentration values opposite to the low ones present in cutaneous burn. Finally, the enzyme activity has an independent pattern from that of the other components of the renin angiotensin aldosterone system. The evaluation of ACE activity may be a marker of pulmonary damage in smoke inhalation.

Management of burns of the hands in children.

Burns of the hand occur in children when the infant or toddler suffers a scald burn or a contact burn to the palm of the hand. Older children frequently suffer burns from experimenting with matches or gasoline. Although burns of the hand in children are not always as deep as in adults, optimal treatment involves the correct acute management, with skin grafting and proper splinting and physical therapy playing a large role, as well as long-term follow-up due to the excessive scar tissue that may form and the continued growth of the child's hand. The psychosocial needs of the burned child, including an understanding of the nature of child abuse and/or neglect, are also important.

Upper and lower lip reconstruction using the step technique.

The step technique for lip reconstruction is a simple, flexible, one-stage operation that allows reconstruction of full-thickness defects spanning up to two-thirds of the lower lip and, in our experience, one-half of the upper lip without violating the opposite lip or using distant advancement flaps. Twelve patients, ranging in age from 24 to 86 years, underwent full-thickness lip excisions for squamous cell and deeply invading basal cell carcinomas. Reconstruction was achieved by advancing the remaining lateral lip elements to close the defects in a stepwise fashion without violating the remaining orbicularis oris muscle. All patients had a symmetrical, mobile, oral sphincter with intact commissures, adequate buccal sulcus, no symptomatic microstomia, and normal sensation at the completion of the procedure. There have been no recurrences in a nine-month to four-year follow-up, and satisfactory aesthetic results were achieved.

Sural nerve neurocutaneous cross-foot flap.

Managing heel ulcers has proved frustrating because of the tendency for recurrence despite satisfactory use of grafts and flaps. This predisposition for continual breakdown is invariably associated with the loss of sensation. A neurocutaneous cross-foot flap was used to provide coverage and sensation to a heel after a degloving injury. Initially a full-thickness skin graft was used but resulted in a chronic, infected ulcer. Local tissue was not available for coverage. The neurocutaneous flap was based over the distribution of the sural nerve of the opposite foot. After proper delay, the flap was transferred. When the pedicle was divided, the sural nerve was anastomosed to the sural nerve in the recipient leg. This procedure has provided adequate padding and good sensation to the heel, preventing recurrence in this very active patient.

Prolactin, corticotropin, and gonadotropin concentrations following thermal injury in adults.

The concentration of serum prolactin (PRL), plasma corticotropin (ACTH), serum follicle stimulating (FSH), and luteinizing (LH) hormones were measured in 28 adult burned patients (25 males and three females). Morning and night determinations were performed for each hormone. Serum PRL was elevated in males up to the fourth week after the thermal injury. Plasma ACTH increased significantly on the second day postburn and returned gradually to normal on the fifth; serum FSH and LH increased on day 1, then decreased significantly on day 2 and remained low for about 2 weeks. In females, while PRL increased significantly, the gonadotropins were slightly elevated and the ACTH remained within normal limits for the 3 days during which it was possible to study these patients. In all subjects the circadian rhythm of the four measured hormones showed significant variations from the normal pattern.

Latissimus dorsi myocutaneous flap in Poland syndrome.

We present a new approach to the old problem of congenital chest wall malformation--an approach that is anatomically reliable, physiologically sound, and cosmetically pleasing. The procedure used the patient's own tissues, thus avoiding the problem associated with the use of a foreign body, such as a silicone mammary implant. In addition, no loss of muscle mass is seen due to the retention of the normal neurovascular supply to the latissimus dorsi muscle.

Surgical treatment of hidradenitis suppurativa of the axilla.

We review our surgical experience with hidradenitis suppurativa of the axilla at Cook County Hospital during the years 1963 to 1972. The operation for this entity described by Pollock et al has (1) reduced the length of hospitalization, (2) increased the rate of primary healing and reduced the period of secondary healing, (3) allowed a great amount of tissue to be excised, (4) permitted both axillae to be operated on at once (without incapacitating the patient), (5) avoided the need for skin grafting, and (6) has had less morbidity for those patients in whom primary healing is not achieved. We believe the method reported by Pollock et al is now the treatment of choice for this disease.
