This study was conducted to determine whether there is an association between the removal of the corrugator supercilii muscle and the elimination or significant improvement of migraine headaches. Questionnaires were sent to 314 consecutive patients who had undergone corrugator supercilii muscle resection during endoscopic, transpalpebral, or open forehead rejuvenation procedures. The patients were queried as to whether they had a history of migraine headaches and, if so, whether the headaches significantly improved or disappeared after surgery. If the answer was affirmative, then the patients were further questioned about the duration of the improvement or cessation of the headaches and the relationship to the timing of the surgery. After an initial evaluation of the completed questionnaires, a telephone interview was conducted to confirm the initial answers and to obtain further information necessary to ensure that the patients had a proper diagnosis based on the International Headache Society criteria for migraine headaches. The charts of the patients who had migraine headaches were studied to ascertain and classify the type of surgery they had undergone. Patient demographics were reviewed, and the results were statistically analyzed. Of the 314 patients, 265 (84.4 percent) either responded to the questionnaire, were interviewed, or both responded to the questionnaire and were interviewed. Of this group, 16 patients were excluded because of the provision of insufficient information to meet the International Headache Society criteria, the presence of organic problems, and other exclusions mandated by study design. Thirty-nine (15.7 percent) of the remaining 249 patients had migraine headaches that fulfilled the Society criteria. Thirty-one of the 39 (79.5 percent) with preoperative migraine noted elimination or improvement in migraine headaches immediately after surgery (p < 0.0001; McNemar), and the benefits lasted over a mean follow-up period of 47 months. When the respondents with a positive history of migraine headaches were further divided, 16 patients (p < 0.0001; McNemar) noticed improvement over a mean follow-up period of 47 months, and 15 (p < 0.0001; McNemar) experienced total elimination of their migraine headaches over a mean follow-up period of 46.5 months. When divided by migraine headache type, 29 patients (74 percent) had nonaura migraine headaches. Of these patients, the headaches disappeared in 11 patients, improved in 13 patients, and did not change in five patients (p < 0.0001). Ten patients experienced aura-type headaches, which disappeared or improved in seven of the patients and did not change in three of the patients (p < 0.0001). This study proves for the first time that there is indeed a strong correlation between the removal of the corrugator supercilii muscle and the elimination or significant improvement of migraine headaches. 相似文献

The innervation of the accessory flexor muscle of the limbs of several decapod crustaceans was studied by means of vital staining, with methylene blue and electron microscopy. Three patterns of innervation were found. In the first pattern, the distal (DAFM) and proximal (PAFM) heads of the accessory flexor muscle were supplied by two axons (a thick and a thin) which travel in a private nerve along the length of the merus. This pattern was found in the crab (Cancer) and the lobster (Homarus), and conforms to the classical pattern established in the literature. In the second pattern, the nerve to the DAFM is made up of conjoined branches of the flexor and accessory flexor nerves. Consequently, the DAFM receives at least five axons in the portunid crabs, Carcinus, Callinectes, and Ovalipes, and occasionally six axons in Ovalipes. The PAFM in those portunids receives the usual two axons. In the third pattern, based on preliminary observations on the grapsid crab, Pachygrapsus, “super-innervation” of the accessory flexor muscle appears to include not only five axons to the DAFM but also at least three to the PAFM. In all species, methylene blue staining of the axon terminations revealed a regular pattern of blebs which are thought to correspond to synaptic terminals as revealed by electron microscopy. 相似文献

The authors, a plastic surgeon (Dirnberger) and a neurologist (Becker), conducted this study after reading the article by of Bahman Guyuron et al. in the August 2000 issue of Plastic and Reconstructive Surgery (106: 429, 2000). Sixty patients were operated on between June of 2001 and June of 2002; postoperative follow-up ranged between 6 and 18 months. Patients' charts were reviewed to confirm the diagnosis of migraine headache according to the criteria of the International Headache Society. Sixty patients (13 men and 47 women) from Austria and four neighboring countries took part in the study. The patients were divided into three groups, based on the severity of their migraines: group A comprised patients with up to 4 days of migraine per month; group B included patients with 5 to 14 days of migraine per month; and group C was composed of patients with more than 15 days of headache per month ("permanent headache") or evidence of drug abuse and drug-related headaches. The effectiveness of the operation was evaluated using the following factors: percentage reduction of headache days; percentage reduction of drugs; percentage reduction of side effects, severity of headaches, and response to drugs; and patient grade of personal satisfaction, using a scale from 1 to 5 [1 = excellent (total elimination of migraine headache) to 5 = insufficient or no improvement]. From the entire group of 60 patients, 17 (28.3 percent) reported a total relief from migraine, 24 (40 percent) reported an essential improvement, and 19 (31.7 percent) reported minimal or no change. Patients with a rather mild form of migraine headache had a much better chance (almost 90 percent in group A and 75 percent in group B) to experience an improvement or total elimination of migraine than those patients (n = 27) from group C with severe migraine, "permanent headaches," and drug-induced headaches. Contrary to the reports by Guyuron, 11 patients who had a very favorable response immediately and in the first weeks after the operation experienced a gradual return of their headaches to preoperative intensity after about 4 postoperative weeks. After 3 months, the results in all patients could be declared permanent. All side effects, such as paraesthesia in the frontal region, disappeared in all patients within 3 to 9 months. 相似文献

Fifty-two isolated spleens and 17 corpses of newborns and children up to 3 years of age have been studied. Preparation, visirographic and morphometric methods have been used. During the newborn and suckling age periods the spleen is projected in three regions: in the epigastrum, in the left subcostal and in the left lateral areas of the abdomen, and during early infancy--only in the left subcostal and in the left lateral area of the abdomen. The anterior end of the spleen beginning from the newborn period up to the early infancy comes down 1-2 vertebrae. The angle formed by the longitudinal axis of the spleen and the horizontal plane running across its anterior end increases. The spleen changes its form from the transitional one in newborn towards a long one in early infancy. During early infancy the spleen mass increases 4.6 times as compared to the newborn period, its length--1.8 and its width and thickness--1.7 times. 相似文献

Summary Caesium cation toxicity observed previously in light- and dark-germinated tomato seedlings Lycopersicon esculentum L.) without calcium cation supplementation in the germination media was also observed here in tomato seedlings germinated in light and dark environments on mixtures of caesium and calcium cations. This non-amelioration of caesium cation-induced toxicity by externally supplied calcium cations in light- and dark- germinated tomato seedlings was evident in five cultivars, thus demonstrating that this phenomenon was not cultivar specific. 相似文献

The investigation of the external iliac lymph nodes has been performed in 152 preparations of corpses of mature persons of both sex, who died from causes not connected with any disease of the lymphatic system, lower extremities and pelvic organs. The external iliac lymph nodes and their afferent and efferent lymphatic vessels have been revealed by means of interstitial injection of the lower extremities and pelvic organs, as well as by means of direct injection of Gerota mass into the lymphatic vessels. Form, amount, dimensions and topography of common iliac lymph nodes have been studied. Lymphatic vessels, running from certain parts and organs of the body to various subgroups of the external iliac lymph nodes have been described, as well as efferent lymph vessels of these nodes. The external iliac lymph nodes are constant formations; the largest of them--lymph nodes of the lacuna--are nodes of the I step for the lower extremity lymph vessels. In 54% of cases in persons of both sex positive (right-sided) asymmetry has been revealed. Total amount of the iliac lymph nodes prevails in men, while their size is greater in women. The size of these nodes in persons of both sex is greater to the left than to the right. There are connections (in 3% of cases) between the external iliac lymph nodes and aortal and lumbar nodes of the opposite side. 相似文献

Suture techniques for reshaping the nasal tip have been in use for many decades. However, the past two decades have been the most influential in the advancement of the procedures commonly used today. This report details the origin of the major tip suture techniques and tracks their evolution through the years. The early techniques in tip rhinoplasty share a basic principle: the sacrifice of lateral crus integrity to augment the middle and medial crural cartilage to gain tip projection and height. These techniques often disrupt the support mechanisms of the tip lobule, leading to undesirable postoperative results, including supratip fullness, tip asymmetry, tip drop, and an overoperated appearance. Modern nasal tip surgery is founded on the philosophy that suture placement does not simply secure partially excised sections of alar cartilage; rather it aims to directly reshape and reposition the various nasal tip components. The principal suturing methods available in the repertoire of today's rhinoplasty surgeon are the medial crural suture, the middle crura suture, the interdomal suture, the transdomal suture, the lateral crura suture, the medial crura anchor suture, the tip rotation suture, the medial crura footplate suture, and the lateral crura convexity control suture. This report acknowledges past contributions to nasal tip surgery and looks at the recent evolution of techniques commonly used today. 相似文献
