BACKGROUND: The main trunk of the hypoglossal nerve enters the tongue body anterior to the hypoglossal muscle and runs in a medial direction. RESULTS: Close to the lingual septum, the nerve changes its direction to a superior path and in a second change to an anterior path. The terminal branches disperse in the apical part of the tongue. To avoid injury of the hypoglossal nerve during surgical procedures within the body of the tongue, two fingerbreadth areas should be preserved. The first area lies in a vertical direction, from the entry of the nerve up to the longitudinal superior and inferior muscles. The second area extends from here in an anterior direction up to the lingual apex. 相似文献

The purpose of this study was to investigate whether in patients with a clinical unilateral temporomandibular joint (TMJ)-related finding of internal derangement type (ID)-III (disk displacement without reduction) in combination with TMJ-related pain, the intraindividual variable of 'unilateral TMJ ID-III pain' may be linked to subject-related magnetic resonance (MR) imaging findings of TMJ ID, and TMJ osteoarthrosis (OA). The study comprised 48 consecutive TMJ pain patients, who were assigned a clinical unilateral TMJ pain side-related diagnosis of ID-III. Bilateral sagittal and coronal MR images were obtained to establish the presence or absence of TMJ ID and/or OA. Comparison of the TMJ side-related data showed a significant relationship between the clinical finding of TMJ ID-III pain and the MR imaging diagnoses of TMJ ID (P=0.000) and TMJ ID type (P=0.000). There was no correlation between the clinical finding of TMJ ID-III pain and the MR imaging diagnosis of TMJ OA (P=0.217), nor between the MR imaging diagnosis of TMJ OA and that of TMJ ID (P=0.350). Regarding the diagnostic subgroups of TMJ ID, a significant relationship was found between the presence of TMJ OA and the MR imaging diagnoses of TMJ ID type(P=0.002). Use of the Kappa statistical test indicated a fair diagnostic agreement between the presence of TMJ ID-III pain and the MR imaging diagnosis of disk displacement without reduction (DDNR) (K=0.42). The results suggest that TMJ ID-III pain is related to TMJ-related MR imaging diagnoses of ID. Further, the data confirm the biological concept of 'DDNR and OA' as an underlying mechanism in the etiology of TMJ-related pain and dysfunction. 相似文献

PURPOSE: This study emphasizes the significance of maxillofacial injuries in skiing accidents, correlating injury mechanisms and patterns, by evaluating a large population of maxillofacial injuries over a 6-year period. PATIENTS AND METHODS: Between 1991 and 1996, of 5,623 patients showing oral and maxillofacial injuries, 1,859 were sports-related. Records of 579 patients with 882 incidents of oral and maxillofacial injury due to skiing were reviewed and analyzed according to age, sex, type of injury, cause of accident, location, and frequency of fractures. Additionally, the five main injury mechanisms were analyzed. RESULTS: The oral and maxillofacial injuries in 10.3% of all trauma patients, or 33% of all sports-related trauma patients, were due to skiing. A total of 310 patients (53.5%) had facial bone fractures, 236 patients (40.8%) suffered from dentoalveolar trauma, and 336 patients (58%) showed soft tissue injuries. Five major causes and mechanisms of injury existed, namely, 263 falls (45%); 135 collisions with other skiers (23%); 70 individuals struck by their own ski equipment (12%); 46 collisions against stationary objects (8%); and 34 lift-track accidents (6%). Sex distribution showed an overall male-to-female ratio of 1.9:1.0, but varied depending on the injury mechanism. The age distribution ranged from 2 to 81 years. CONCLUSION: The results of this study show the high incidence of oral and maxillofacial injuries due to skiing accidents. Depending on the mechanism of injury, different patterns occur. Facial bone fractures are more likely in collisions with other persons, falls, and collisions with stationary objects, whereas dentoalveolar trauma is more common when persons are struck by their own ski equipment, or when accidents on lift-tracks occur. 相似文献

OBJECT: The goal of this study is to report the incidence and clinical evolution of neurological deficits in patients who underwent resection of gliomas confined to the parietal lobe. METHODS: Patient demographics, findings of serial neurological examinations, tumor location and neuroimaging characteristics, extent of resection, and surgical outcomes were tabulated by reviewing inpatient and office records, as well as all pre- and postoperative magnetic resonance (MR) images obtained in 28 consecutive patients who underwent resection of a glial neoplasm found on imaging studies to be confined to the parietal lobe. Neurological deficits were correlated with hemispheric dominance, location of the lesion within the superior or inferior parietal lobules, subcortical extension, and involvement of the postcentral gyms. The tumors were located in the dominant hemisphere in 18 patients (64%); had a mean diameter of 39 mm (range 14-69 mm); were isolated to the superior parietal lobule in six patients (21%) and to the inferior parietal lobule in eight patients (29%); and involved both lobules in 14 patients (50%). Gross-total resection, documented by MR imaging, was achieved in 24 patients (86%). Postoperatively, nine patients (32%) experienced new neurological deficits, whereas seven (25%) had an improvement in their preoperative deficit. A correlation was noted between larger tumors and the presence of neurological deficits both before and after resection. Postoperatively higher-level (association) parietal deficits were noted only in patients with tumors involving both the superior and inferior parietal lobules in the dominant hemisphere. At the 3-month follow-up examination, five of nine new postoperative deficits had resolved. CONCLUSIONS: Neurological deterioration and improvement occur after resection of parietal lobe gliomas. Parietal lobe association deficits, specifically the components of Gerstmann syndrome, are mostly associated with large tumors that involve both the superior and inferior parietal lobules of the dominant hemisphere. New hemineglect or sensory extinction was not noted in any patient following resection of lesions located in the nondominant hemisphere. Nevertheless, primary parietal lobe deficits (for example, a visual field loss or cortical sensory syndrome) occurred in patients regardless of hemispheric dominance. 相似文献
