摘要:
Women with eating disorders have been disqualified as candidates for plastic surgery. We present a group of 6 young women with bulimia nervosa who presented with clinically symptomatic evidence of macromastia. All patients reported that dysfunctional eating habits, at least in part, where due to breast enlargement. Five patients underwent bilateral reduction mammaplasty. Patients were interviewed postoperatively and reported relief of physical symptoms and improvement in psychological well-being. Symptoms of eating disorders were completely eliminated or greatly reduced. This series has supported the contention that macromastia can produce a distortion of body image and become a secondary cause of eating disorders. Surgical correction of large breasts has improved body image, leads to the amelioration of associated eating disorders, and may in part represent a surgical treatment for a psychological abnormality. The presence of an eating disorder should not, therefore, automatically exclude a patient from surgical consideration. Routine preoperative evaluation of young women seeking plastic surgery should include a set of standard questions regarding eating behaviors.

摘要:
The purpose of this clinical investigation is to confirm the efficacy of eliminating facial wrinkles by injecting botulinum toxin A into mimetic muscles. Fifty-four patients were injected with BOTOX A-14 in the corrugator superciliaris, 19 in the frontalis muscles, and 13 in the orbicularis oculis. Dilution was obtained by adding 4 ml preservative-free saline to 100 IU of BOTOX A. The dose used varied according to the patient. The severity of wrinkles and the intensity of muscle contraction (facial expression) were taken into account. The paralysis obtained in the mimetic muscles was effective for 6 months in 39 patients, 8 months in 10 patients, and 9 months in 1 patient. The results were documented by photographs, videotape, and electromyographies pre- and postin-jection. To preserve the results, 21 patients (39%) demanded a second infiltration to achieve satisfactory results. Neither local nor general adverse effects were noted, except transitory eyebrow palsy in 2 patients, and edema and ecchymosis in 4 patients. The improvement obtained in facial mimetic wrinkles was satisfactory to the patient and to us.

摘要:
The present study describes the techniques available for single-stage sarcoma resection, soft-tissue reconstruction, and radiotherapy for limb preservation in patients who are unable to undergo primary wound closure after a complete soft-tissue resection of their primary sarcoma. From 1989 to 1994, 19 patients (age range, 18–79 years; mean, 51.2 years) underwent radical resection of extremity sarcomas followed by immediate reconstruction. Seven patients had tumors in the upper extremity and 12 patients had tumors in the lower extremity. There were 13 primary tumors and 6 recurrent tumors. Fifteen patients (79%) received radiation therapy, 7 patients by external beam and 8 patients by brachytherapy. Reconstruction included 16 regional flaps in 13 patients and 7 free tissue transfers in 6 patients. Commonly used flaps included the rectus abdominis (N = 5), the latissimus dorsi (N = 4), the anterolateral thigh (N = 4), the reverse-flow radial forearm (N = 2), and the gastrocnemius (N = 2) flaps. Complications included wound breakdown (N = 2), partial skin graft failure (N = 1), hematoma requiring operative evacuation (N = 1), and partial flap necrosis (N = 1). There were no operative mortalities. Eight patients underwent wide local excision, flap closure, and brachytherapy. Mean length of hospital stay for this group was 12.3 days compared with 13.8 days for the remaining 11 patients. There was one complication (13%) in this group and four complications in the remaining patients (4 of 11; 36%). Our study confirms the utility of soft-tissue reconstruction to permit wide local excision with clear margins as well as the delivery of postoperative radiotherapy. It demonstrates the ability of pedicled flaps and free tissue transfers to remain viable and provide sufficient wound coverage in the setting of early postoperative brachytherapy. In addition, this series illustrates the efficacy of a team approach and one-stage therapy for extremity soft-tissue. Sarcomas that includes excision, reconstruction, and early postoperative brachytherapy in a single hospitalization.

摘要:
In patients who undergo oral cavity reconstruction, loss of sensation plays a vital role in producing disturbances in postoperative oral function. Microsurgical techniques have provided a method of addressing this deficit through the use of sensate cutaneous free flaps in which microneural anastomoses are performed between a sensory nerve supplying the flap, and a recipient nerve in the head and neck. The purpose of this study was to compare the cutaneous sensation of the radial forearm flap and lateral arm flap donor sites, the two most commonly used intraoral sensate flaps. For comparison, sensation was also determined in five intraoral sites: the tip of tongue, lateral tongue, cheek, gingiva, and hard palate. Sensation was evaluated at the two potential donor sites in 66 random subjects using static and moving two-point discrimination, thermal sensation differences, and Semmes-Weinstein monofilament pressures. In the same subjects Semmes-Weinstein monofilament pressures were used to evaluate intraoral sensation. Information was recorded on age, sex, smoking and denture status. All four sensory evaluations demonstrated that the lateral arm flap donor site was more sensitive than the radial forearm donor site. Thermal sensitivity differentials (0.52 vs. 0.40°C, p < 0.001), static two-point discrimination (15.4 vs. 15.0 mm, p < 0.2), moving two-point discrimination (5.8 vs. 4.8 mm, p < 0.03), and Semmes-Weinstein monofilament pressures (5.10 vs. 4.08 g per square millimeter, p < 0.001) all indicated a more sensitive lateral arm flap donor site. Older subjects had significantly decreased sensation at both donor sites based on static two-point discrimination and Semmes-Weinstein monofilament testing. No sex differences were noted. Based on Semmes-Weinstein monofilament testing in the mouth, the tip of the tongue is the most sensitive area (2.26 g per square millimeter), followed by the hard palate (3.60 g per square millimeter), the lateral tongue (4.08 g per square millimeter), the cheek (4.77 g per square millimeter), and the gingiva (8.06 g per square millimeter). Smokers had significantly decreased sensation at the tip of tongue and hard palate. Denture wearers had significantly diminished sensation in all intraoral locations except the lateral tongue. Older patients had significantly diminished sensation at all intraoral sites. No sex differences were noted. The lateral arm flap donor site is a more sensitive region than the radial forearm flap donor site. However, the lateral arm flap donor site is less sensitive than the tip of tongue and hard palate, while the radial forearm flap donor site is less sensitive than the tip of tongue, hard palate, lateral tongue, and cheek. This suggests that for certain locations, intraoral sensate flaps may require measures such as sensory reeducation protocols to approach normal recipient site sensation.

摘要:
Persistent or recurrent symptoms following endoscopic carpal tunnel release have been reported in 0.5% to 3% of patients undergoing this procedure. Unfortunately, preoperative risk factors for this complication have not been defined. We reviewed the records of 126 consecutive patients who underwent Agee single-portal endoscopic carpal tunnel release between June 1994 and March 1997. Five patients and six hands required subsequent open carpal tunnel release for persistent or recurrent carpal tunnel syndrome. Fulminant synovitis was identified during open carpal tunnel release in all reexplored patients, and four of the six hands were cured with open release and synovectomy. No recurrences were identified in the group of patients who presented with unilateral carpal tunnel syndrome. The presence of bilateral carpal tunnel syndrome may be a risk factor for persistent or recurrent carpal tunnel syndrome following endoscopic carpal tunnel release.

摘要:
The effects of tissue expansion on the hemodynamic and survival characteristics of reverse-flow island skin flaps were investigated in New Zealand White rabbits. The animals were divided into 3 groups of 15: group I (control) had no surgery prior to flap elevation, group II (nonexpansion) had a noninflated expander, and group III (expansion) had an inflated expander of 80 ml. After 3 weeks of expansion, a reverse-flow island flap based on the distal saphenous pedicle was elevated. A series of hemodynamic studies was performed to test reverse venous flow–in particular, valve competence. Besides observing the reverse flow under an operating microscope, the changes in the intravenous pressure were measured at 0, 5, 15, 30, 60, and 120 minutes after flap elevation. Moreover, reverse-flow resistance (RFR) was measured in each group to test the competence of venous valves. At each time interval, the values of intravenous pressure were significantly lower (p < 0.01) in group III than in the groups I and II. However there was no statistically significant difference between group I and group II. The RFR was measured as 126.7 &phis; 33.52 mmHg in group I, 59.3 &phis; 29.86 mmHg in group II (p < 0.01), and 25.1 &phis; 7.68 mmHg in group III (p < 0.01). Ten days after flap elevation the mean survival of group III (100%) was statistically higher than that of group I (57.4 &phis; 18.3%; p < 0.01) and group II (81.6 &phis; 12.8%; p < 0.05). These findings simply suggest that controlled tissue expansion improves retrograde venous drainage and increases the survival of reverse-flow island flaps in rabbits. Abnormal dilatation of the venous tree and incompetence of the venous valves seem to be the main factors in explaining the decrease in the values of RFR and intravenous pressure in the expanded flaps. The potential mechanisms to explain the effects of tissue expansion, and the clinical implications are discussed.

摘要:
Giant congenital nevi, confluent over 10% to 52% of the body surface area, were treated in 5 pediatric patients with allogeneic skin and autologous cultured epithelium (ACE). The lesions were excised to the adipose tissue and the wound was covered with cryopreserved or fresh allografted skin. Later, the skin surface was abraded and ACE was applied. The size of the cultured graft ranged from 360 to 900 cm2(average, 630 cm2). In 3 patients the wounds healed well. Allograft cryopreservation averaged 50 days. The average interval to ACE application after skin grafting was 10 days. Histological rejection was minimal. In 2 patients the cultured grafts did not take. The wounds were covered with split-thickness skin grafts. In one such patient, a fresh allograft was used. In the other, ACE was applied 27 days after skin grafting. Vigorous rejection reaction was observed. Cryopreservation of allogeneic skin may be important in the treatment of human leukocyte antigen-mismatch patients with giant nevi, and ACE should be applied within 10 days of skin grafting.

摘要:
From January 1994 to October 1995, 5 patients with congenital giant pigmented nevi were treated using artificial dermis with a secondary skin graft from the scalp. The nevus was excised in full thickness and the open wound was grafted with artificial dermis. About 3 weeks later, thin split-thickness skin grafting on the newly synthesized, dermislike tissue was required. We chose the scalp as the donor of the secondary skin graft. Epithelialization of each donor site was completed within 1 week. In addition, the donor site was not complicated with alopecia or hypertrophic scars. Morbidity at the donor site was minimized and favorable tissue quality of the grafted skin was obtained. The clinical results revealed that the scalp was a favorable donor of a secondary skin graft for the treatment of giant pigmented nevus with artificial dermis.

摘要:
The cutaneous vascular anatomy of the mid-dorsum in the rat and its role in flap design was studied in the rat. The investigation consisted of anatomic dissection, methylene blue injection into the axial artery, and flap harvesting in live animals. Dissection and injection revealed that the mid-dorsum of the rat derives its blood supply largely from the 10th intercostal artery, here referred to as themiddle dorsal artery,which originates from the lateral aspect of the thoracic aorta. The cutaneous vascular territory of the middle dorsal artery was defined as follows: the medial border, midline of the dorsum; the lateral border, midaxillary line; the cephalic border, a line joining the medial and lateral borders midway between the level of the axilla proximally and 1 cm above the base of the rib cage distally; and the caudal border, a line drawn midway between the latter point proximally and the anterior superior iliac spine distally. Both unilateral and bilateral vascular pedicled island cutaneous flaps were harvested in living rats based on and exceeding the vascular territory delimited by methylene blue injection. Flaps limited to this territory with intact middle dorsal arteries showed total survival, while oversized flaps underwent partial necrosis peripherally. Because of its simplicity, reliability, and consistent vascularity, this flap has potential applications in the study of flap hemodynamics.

摘要:
The standard rat epigastric artery flap has been a very reliable model for flap research. The purpose of this study was to describe a modified design of this flap that included only the medial branch of the epigastric artery. Axial-pattern epigastric island skin flaps, measuring 8 × 8 cm, were raised in two groups of Sprague-Dawley male rats. In group A (N = 20) the vascular pedicle consisted of the main trunk of the epigastric vessel and both medial and lateral branches. In group B (N = 20) the flap was based solely on the medial branch of the epigastric artery, excluding the large lateral branch. The flaps were elevated and then sutured back to their beds. Flap survival was studied and the amount of viable skin in both groups was compared 1 week later. The rats were photographed using a digital camera and the images were analyzed using imaging software. The mean percentage surviving flap area in group A was 86.24% and in group B it was 69.72%, which is statistically significant (p < 0.001). We believe that this flap model, with its new modified design that includes a larger flap and inclusion of only the medial branch, will broaden its application to microsurgery. The main advantage of this flap over the conventional epigastric flap is that in this model it is possible to achieve predictable and consistent necrosis in the random extension of the flap.
