ABSTRACT
Acute hematoma remains one of the most frequently encountered complications after face-lift surgery. Several risk factors inherent to the patient and omission of certain intraoperative regimens are considered to cause hematoma. Significant risk factors include high blood pressure and male gender. Possible intraoperative regimens for the prevention of hematoma include tumescence infiltration without adrenaline, clotting of raw surfaces with fibrin glue, usage of drains, and application of compression bandages. However, little attention has been paid to postoperative measures. To examine whether different regimens in the postoperative phase can influence the incidence of hematoma, all face-lift patients who underwent surgery by a single surgeon in two different clinics (n = 376) with two different postoperative regimens were evaluated over the course of 3 years. In group 1 (n = 308), all postoperative medication was administered on request including medication for pain control, blood pressure stabilization, and prevention of nausea and vomiting as well as postoperative restlessness and agitation. In group 2 (n = 68), this medication was administered prophylactically at the end of the operation before extubation. The hematoma rate was 7% in group 1 and 0% in group 2. This study showed that the prophylactic use of medications (e.g., analgesics, antihypertonics, antiemetics, and sedatives) during the postoperative phase is superior to making drugs available to patients on request and can decrease the occurrence of acute hematoma in face-lift patients.

BACKGROUND: Angiogenesis and lymphangiogenesis are considered to play key roles in tumour growth, progression and metastasis. However, targeting tumour angiogenesis in clinical trials showed only modest efficacy. We therefore scrutinised the concept of tumour angiogenesis and lymphangiogenesis by analysing the expression of crucial markers involved in these processes in primary breast cancer. METHODS: We analysed the expression of angiogenic, lymphangiogenic or antiangiogenic factors, their respective receptors and specific markers for endothelial and lymphendothelial cells by quantitative real-time RT-PCR in primary breast cancer and compared the expression profiles to non-cancerous, tumour-adjacent tissues and breast tissues from healthy women. RESULTS: We found decreased mRNA amounts of major angiogenic and lymphangiogenic factors in tumour compared to healthy tissues, whereas antiangiogenic factors were upregulated. Concomitantly, angiogenic and lymphangiogenic receptors were downregulated in breast tumours. This antiangiogenic, antilymphangiogenic microenvironment was even more pronounced in aggressive tumours and accompanied by reduced amounts of endothelial and lymphatic endothelial cell markers. CONCLUSION: Primary breast tumours are not a site of highly active angiogenesis and lymphangiogenesis. Selection for tumour cells that survive with minimal vascular supply may account for this observation in clinical apparent tumours.

The presence of three phalanges in the first digit is considered to be a relatively rare congenital hand malformation. Six groups of this deformity can be distinguished: some digits are opposable, others resemble a non-opposable five-fingered hand. In cases of a hypoplastic thenar region with a restrained opposition, a clear verification of thumb-specific musculature has been hardly possible. We report of the possibility of a non-invasive identification of thumb-specific muscles by means of magnetic resonance imaging.

A quality assurance study was undertaken three years after beginning the vertical scar breast reduction technique. We examined the rate of early and late complications (major and minor) and compared these to the formerly used inverted-T scar and L scar breast reduction techniques. Inverted-T scar breast reductions have an early complication rate of up to 20% and a late complication rate of 20-30%. Our vertical scar breast reduction is a modified Lassus technique, incorporating a geometrically based and measurable preoperative marking of the breast, a superior pedicle, a central breast resection, an intraoperative positioning of the nipple-areola complex, and occasionally a periareolar skin resection.In the time span examined (September 1998-December 2001) 153 patients could be included in the study. The resection weight per breast ranged from 60 to 1262 g (mean 390+/-210 g, median 380 g). The early complication rate (hematoma, seroma, wound dehiscence, wound infection and necrosis) was 21.6%. Of these cases, 19.6% were minor complications. The late complication or imperfection rate was evaluated very strictly using the standardized, extended scheme of Ferreira (problems of volume, shape, symmetry, areola, scars and position of the breast on the thorax) and was 26%. Major late complications necessitating a reoperation occurred in 11.1% of cases. These complication rates compare well to those of other vertical breast reduction techniques and T scar reductions in our own clinic and in the literature. Given that the vertical scar breast reduction method also results in shorter scars and a significantly better, long-lasting breast projection, this technique is clearly justified to remain the standard method at our clinic.

With the goal of ensuring maximal safety, surgeons tend to apply antibiotic prophylaxis generously to patients undergoing selective operative procedures. However, the indiscriminate or inappropriate use of prophylactic antibiotics i) leads to the selection of resistant microbial organisms and ii) results in an increase in general medical treatment costs. Given this controversy, the clinic of reconstructive surgery implemented in 1999 a set of guidelines for the proper use of antibiotics. Antibiotic prophylaxis was defined as a pre- or perioperative application of antibiotics as a single to maximum triple-shot dose. It was recommended only for operations involving special risk factors or the implantation of alloplastic material. The recommended medication of choice was the widely-accepted standard first-generation cephalosporin product Cefazolin. We have carried out a quality control trial to analyse prospectively our own experience with the implementation of these guidelines and to compare results with a retrospective group of patients. A total of 792 patients (441 in the retrospective group, 351 in the prospective group) were enrolled in the study. About one third of all patients received an antibiotic prophylaxis. Of these, about 3/4 received the antibiotic prophylaxis without having one of the above-mentioned indications. We observed that 35% of all prophylaxis were given for breast surgery, followed by surgery for scar revisions and lipodystrophy. The most commonly used antibiotic was Cefuroxim rather than Cefazolin. There was no significant reduction in the general application of antibiotic prophylaxis yet apparent in the prospective group. However, there was a clear increase in the use of Cefazolin from 0.2% to 13.2%. We conclude that guidelines can be created to reduce the incidence of uninformed and inappropriate decisions, but their implementation requires time, motivation, and thorough and repeated information campaigns.

The causes of bilateral absence of the nipple-areola complex in men are seldom congenital, but attributable rather to destruction as a result of trauma, or after mastectomy in female-to-male transsexuals and in male breast cancer, or after the correction of extreme bilateral gynecomastia. Such a bilateral loss becomes a major reconstructive challenge with respect to the configuration and localization of a new nipple-areola complex. Because there is very little information available in the literature, we carried out a cross-sectional study on the configuration and localization of the nipple-areola complex in men.A total of 100 healthy men aged 20 to 36 years were examined under standardized conditions. The first part of the study dealt with the configuration of the nipple-areola complex (dimensions, round or oval shape). The second part concentrated on the localization of the complex on the thoracic wall with respect to anatomic landmarks and in correlation to various parameters such as weight and height of the body, circumference of the thorax, length of sternum, and position in the intercostal space. Of the 100 subjects examined, 91 had oval and seven had a round nipple-areola complex. An asymmetry between the right and the left side was found in two cases. The mean ratio of the horizontal/vertical diameter of an oval nipple-areola complex was 27:20 mm and the mean diameter for a round nipple-areola complex was 23 mm. The center of the nipple-areola complex was in the fourth intercostal space in 75 percent and in the fifth intercostal space in 23 percent of the subjects. To localize the nipple-areola complex on the thoracic wall de novo, at least two reproducible measurements proved to be necessary, composed of a horizontal line (distance from the midsternal line to the nipple = A) and a vertical line (distance from the sternal notch to the intersection of line A, = B). The closest correlation for the horizontal distance A was given by the circumference of the thorax: A = 2.4 cm + [0.09 x circumference of thorax (cm)], (r = 0.68). The best correlation to calculate the vertical distance B was found using the distance A and the length of the sternum: B = 1.2 cm + [0.28 x length of sternum (cm)] + [0.1 x circumference of thorax (cm)], (R = 0.50). In cases of bilateral absence, we recommend creating an oval nipple-areola complex in men. The appropriate localization can be calculated by means of two simple equations derived from the circumference of the thorax and the length of the sternum.

Modern strategies for preventing or controlling pain and anxiety demand a premedication for operations using local anesthesia and for those using sedation or general anesthesia. For optimal patient care, the premedication should be given orally and, with respect to the outpatient basis of the operations, should have a short recovery period. Midazolam, one of the most favored premedications for general anesthesia, has been recommended as a premedication for operations using local anesthesia as well. However, midazolam has only sedative-anxiolytic effects and does not reduce pain sensation, which should be mandatory for operations using local anesthesia. A further requirement is the maintenance of stable hemodynamics for the prevention of postoperative hematomas, especially in the face. For these reasons, another premedication meeting all requirements (anxiolysis, analgesia, and stable hemodynamics) was researched. A randomized, double-blind prospective study was performed from March of 1997 to June of 1998. Five groups totalling 150 patients were included in the study; each group contained 30 patients who had operations performed solely on the face. In the first four groups, the effect of midazolam (0.15 mg/kg(-1)), morphine (0.3 mg/kg(-1)), and clonidine (1.5 microg/kg(-1)) administered orally was compared with a placebo. The fifth group was the control group and received no premedication. To evaluate the effects of the premedications, a corresponding questionnaire was completed independently by the patient and surgeon. With regard to the anxiolytic or analgesic properties of the premedication, 61 percent of the patients preferred pain reduction to anxiety control, and 24 percent of patients preferred reduction of anxiety. The remainder insisted on a reduction of both properties (8 percent) or had no preference (7 percent). Reduction of anxiety was largest in the midazolam and the clonidine groups, but the difference was not significant. The least pain during the application of local anesthesia was experienced by the morphine group (37 percent) and the clonidine group (33 percent), in contrast to the midazolam group (60 percent) (p = 0.04). Morphine and clonidine met the requirements of pain reduction equally well. Nevertheless, considering the rate and intensity of adverse effects with respect to hemodynamic compromises, nausea, and emesis, clonidine is even better suited as an oral premedication for operations on the face using local anesthesia.

Standardized experimental nerve crush attempts should include the number, duration, and intensity (amount of pressure) of crushes. The authors have developed a new crushing device, a clamp with which predetermined forces can be applied to nerves. This allows the exertion of different, standardized forces to crush a nerve within a scale that produces second-degree injuries. The main advantages of the clamp are that it is small, although very robust, is purely mechanical, and is easy to handle. The jaws of the clamp are not serrated, so that pressure on the nerve is uniformly transmitted. To avoid unintended nerve damage, the edges of the jaws are smoothly rounded off. The closure of the clamp is mechanized by a spring. As the spring is exchangeable, any number of different preloads are available. The force can be varied, according to different requirements, and is applicable to variantly thick nerves in any experimental animal, thus enhancing standardization, and making cross-over comparisons of experimental study results possible.

To study nerve degeneration and regeneration the peroneal nerve of the rabbit is a rewarding experimental model. The access to the nerve should be as atraumatic as possible and no muscular tissue should be incised or transected in order to lower postoperative morbidity and enhance the welfare of the animals. Given such conditions it is not possible to expose the undistributed proximal and central parts of the peroneal nerve from the intervertebral notch to its passage through the lateral head of the gastrocnemius muscle by a single approach, but rather a two-level incision is required. Such an approach to the peroneal nerve was carried out on 24 New Zealand White rabbits. The amount of postoperative pain was estimated by the rabbits social and feeding behaviour. The observed overall impairment was impressively low. This approach has been shown to be beneficial for the animals, and is atraumatic and should be strongly recommended.

Although a variety of electrophysiological and morphological tests are available for studying nerve regeneration in animals, these endpoints do not necessarily correlate with the return of muscle function. Recent efforts have focused on the assessment of function as the endpoint of nerve regeneration. One of the best known of these tests is the sciatic function index in rats. For rabbits, the toe-spreading reflex has been suggested as a valuable index of peroneal function. We examined the reliability and sensitivity of the toe-spreading reflex in a study of nerve regeneration of the peroneal nerve in 10 New Zealand White rabbits. Eleven weeks after the transection and immediate suturing of the peroneal nerve in both hind legs (at two slightly different sites), a toe-spreading reflex could always be elicited on that side where the level of the severed nerve was closer to the dependent muscles. Also on this hind leg the muscle weight of the peroneal target muscles was significantly higher (P = 0.031) than on the contralateral side, which corresponds well to the results of the toe-spreading reflex. The toe-spreading reflex is an excellent and sensitive indicator of the onset of motor recovery in the peroneal nerve-dependent muscles of rabbits. Even small differences in the localization of lesions in both hind legs can be differentiated with this test.

Experimental nerve surgery involves test procedures, including those for nerve lesions in continuity, that leave no visible traces of impairment after surgery. In such cases, non-resorbable sutures are usually used to mark the lesion sites on the nerves. However, this method has two drawbacks: it is not completely atraumatic, and may be frustrating due to displacement of the suture material. The authors demonstrate the use of carbon tattoo pigment to mark nerve lesions permanently, thus allowing their identification reliably at any later date. Following successful preliminary experiments, the tattooing procedure was used in 12 New Zealand White rabbits that had been operated on for a specific nerve regeneration problem. Altogether, 56 tattoo marks were set. The small pigment spots were well-preserved and clearly visible during a second and third operation 4 and 15 weeks later. Histologic examination identified the carbon granules in the outer epineurium; there were no signs of inflammation. This simple, atraumatic, inert, and permanent method for nerve markings in the experimental animal is recommended.

The use of vertical-scar breast reduction techniques is only slowly increasing, even though they have been advocated by Lassus and Lejour and are requested by patients. Possible reasons why surgeons are reluctant to use these techniques are that they are said to be more difficult to learn, they require considerable experience and intuition, and their applicability is confined to small breasts. Several surgeons have developed modifications, combining vertical-scar breast reduction techniques with details of the familiar inverted-T-scar technique. We present a procedure involving two further modifications of the vertical-scar breast reduction technique: first, a standardised, geometrical preoperative drawing from our superior-pedicle T technique, with the aim of establishing a reproducible method of reduction requiring no particular intuitive touch, and, second, the addition of a periareolar skin resection, to give the breast the desired round shape. Between September 1998 and December 1999 we used this technique in a prospective series of 52 patients. The median resection weight was 450 g. The maximal postoperative follow-up was 15 months. There were no acute postoperative complications necessitating reoperation. The late complication rate was within the expected range for such procedures (seven patients, 13.5%) and included vertical-scar widening, areolar distortion, residual wrinkles due to incomplete shrinkage of the undermined skin in the inferior pole and asymmetry of the breast. This procedure enables us to offer patients with moderate to marked hypertrophy a reproducible versatile vertical breast reduction technique. The technique is easy to teach and easy to learn, especially for those who are familiar with the superior pedicle inverted-T-scar technique.

Nevus sebaceous has been considered a relatively infrequent and unimportant congenital hamartoma for plastic surgeons unless the lesions are so big that they require a demanding defect closure. As the dignity of such tumors is primarily benign and the malformed sebaceous glands are localized abnormally high in the dermis, the temptation is appealing not to excise these tumors any more but to eradicate them by laser beam therapy. Yet a nevus sebaceous not only affects sebaceous glands but includes various other malformations of the affected skin and its appendages. In addition, different malignant tumors may occur in nevus sebaceous, even in children and young adults. We encountered 4 such malignant tumors of 18 nevi sebaceous operated on from 1989 to 1997. All nevi had been unsuspicious macroscopically. In three patients, one of them only 15 years old, an associated basal cell carcinoma was found. In the fourth patient there was a mixture of three additional tumors, a cystadenoma, a keratoacanthoma, and a basal cell carcinoma, besides the sebaceous malformations. These findings have two consequences: first, to continue surgical treatment of nevus sebaceous instead of dermabrasion or dermablation and to have the specimen examined histologically and, second, to excise such tumors as early in childhood as possible.

OBJECTIVE: Nevus sebaceus has been considered a relatively infrequent and unimportant congenital hamartoma for plastic surgeons, unless the lesions are so big that they require a large closure of the defect. As such tumors are primarily of a benign nature and the malformed sebaceus glands are located abnormally high in the dermis, surgeons are tempted not to excise the tumors but to eradicate them by dermabrasion or laser beam therapy. Yet, a nevus sebaceus does not only affect sebaceus glands but includes various other malformations of the affected skin and its appendages. In addition, different malignant tumors may occur in nevus sebaceus, even in children and young adults. MATERIALS AND METHODS: We encountered 4 such malignant tumors out of 18 nevus sebaceus operated from 1989 to 1997. All nevi had been clinically inconspicuous. RESULTS: In three patients, one of them being only fifteen years old, an associated basal cell carcinoma was found. The fourth patient had a mixture of three additional tumours, a cystadenoma, a keratoacanthoma and a basal cell carcinoma besides the sebaceous malformations. CONCLUSION: These findings have two consequences. The first is to continue surgical treatment of nevus sebaceus instead of dermabrasion or dermablation and to have the specimen examined histologically. The second consequence is to excise such tumors as early as possible.

Atraumatic haemorrhages in the posterior cricoarytenoid (PCA) muscles can be observed for from 1% to 9% of various causes of death. It has been claimed that there is an association between these findings and the cause of death, particularly coronary death. Additionally it has been assumed that haemorrhages in the PCA muscles may be caused by an asphyxial mechanism and it has even been suggested that the haemorrhages may be a "sign" which could be used to differentiate between natural and unnatural death. Because of the differing views we carried out additional research into the course of these haemorrhages. Six characteristic cases out of 2060 autopsies with macroscopically diagnosed haemorrhages in the PCA muscles are presented. The six cases included acute heart failure, death caused by bolus, drowning, trauma of brain and skull, exsanguination from polytrauma and choking after aspiration of vomit. These cases were completely different with regard to all the circumstances of death. On the basis of these findings and in contrast to the literature it cannot be shown that proofs exist for a correlation between the haemorrhages and the causes and the manner of death. As a consequence it must be stated that haemorrhages in the PCA muscles do not have any diagnostic significance.

Until now, it has been taken for granted that the point of emergence of the supraorbital nerve is by way of a notch or a foramen at the border of the inner to the medial third of the supraorbital rim. In contrast to several anatomic textbooks, we noticed that the exit point was repeatedly not at the site where anticipated when implanting lid springs for facial palsy. This gave us the idea of investigating these variations and how big they are, because most open and recent endoscopic forehead lift techniques have relied on a constant exit point of the supraorbital nerve. A total of 507 macerated skulls (1014 orbits) from three anatomic collections in Austria and Germany were studied. All skulls were adult European skulls gathered from the prehistoric age up to the twentieth century. Additionally, 18 fixed cadavers (36 orbits) and 25 fresh cadavers (50 orbits) were studied. These data were not included in the statistical analysis but in the discussion. The anatomic measurements on the skulls were carried out with an anthropometric calliper. The examinations concentrated on the configuration (notch/foramen) and the number of exit point(s) on the supraorbital rim, the vertical distance from the supraorbital rim, and the distance from the nasion to the various exit point(s). Combining all of these parameters, 74 percent of the skulls showed asymmetric findings between the right and left orbits. In 15 percent of both orbits, the supraorbital nerve left the orbital cavity already in its two branches, the medial and lateral branch, either through a notch or a foramen, the foramen being sometimes the exit of a supraorbital canal. The average distance from the nasion to the frontal notch/foramen was 25 mm on both orbits (range 16 to 55 mm) and to the supraorbital notch/foramen 31 mm (range 20 to 49 mm). The largest vertical distance from the supraorbital rim to its farthest exit point was 19 mm. Other than what is cited in literature, the variations concerning the configuration and the distance of the exit point(s) of the supraorbital nerve were so significant that all forehead operations, especially those using endoscopic techniques, must take into account these findings.

Quality is essentially based on excellent training. Therefore, all medical disciplines in Austria, including the Plastic Surgery, have to orientate on EU-standards including efforts to adapt the surgical training. To gain an overall impression of the present training situation in Austria, an anonymous questionnaire was sent to all the 25 trainees in Plastic Surgery in summer 1995. Eight centres were involved throughout the country. The questions covered quality of training, reference departments, rotation in training, and postgraduate studies, 52% of the questionnaires were sent back. The conclusions resulting from the questionnaires are the following: unrestricted passing of plastic surgery know-how, provision of reference departments, implementation of rotation for training, carrying out of all operations listed in the EU-catalogue, regular postgraduate training. Only in this way excellently trained plastic surgeons with a strong self confidence can be a convincing counterpole to other fields of surgery which increasingly lay claim to Plastic Surgery terrain.

There is a myriad of proposals for nasal defect closure. One of the older concepts, the so-called topographical concept, adheres to the nasal subunit principle without taking into consideration textural details of the nasal skin such as thickness and mobility. In a newer concept, a morphological concept, the texture of the nasal skin is a basic consideration for defect closure. The morphological or textural concept demands defect closures only with local flaps of nearly identical texture located within the "unit" nose. In order to find out how the morphological concept influenced our operative design, we carried out a retrospective study from 1988 to 1995 checking the defect closure of all basal cell carcinoma on the nose. Of 598 basal cell carcinoma operated in the face, 141 were located on the nose. During the first years, free skin grafts and regional flaps dominated our operative design, in recent years the use of local flaps according to the criteria of the morphological concept increased significantly, leading not only to functional but also to more aesthetic results.

Unilateral hypoplasia of the breast and the pectoralis muscle with a missing anterior axillary fold as part of Poland's syndrome are of major concern, especially for women. The latissimus dorsi is one of the most suitable flaps for breast and anterior thorax reconstructions but it may be hypoplastic or absent. If so, a free tissue transfer of the contralateral latissimus dorsi muscle is the next possible option for reconstruction. As Poland's syndrome is additionally associated with vascular malformations of the diseased hemithorax such as hypoplastic or missing vessels, a preoperative angiography is mandatory for planned microvascular tissue transfer.
