Sensitivity,Specificity, and the Predictive Value of Facial Electromyographic Data in Diagnosing Myofascial Pain-Dysfunction

Studies have shown uniformly that myofascial pain-dysfunction/temporomandibular (MPD/TM) patients have higher electromyographic (EMG) activity in the head-neck muscles than do non-MPD/TM subjects. However, no attempt has been made to use facial EMG data in diagnosing MPD/TM conditions. This paper explicates four concepts that can, in principle, serve to guide individual diagnosis using EMG data. It then reports an experiment in which resting facial EMG data were acquired from MPD patients and control subjects, and it evaluates preliminarily the diagnostic utility of the EMG information. The conclusion is offered that diagnosis via EMG is sufficiently promising to justify additional research.     

Facial aesthetics: 2. Clinical assessment

The clinical ability to alter dentofacial form requires an understanding of facial aesthetics. This is vital for any clinician involved in treatment that will alter a patient's dentofacial appearance, whether through orthodontics, facial growth modification, corrective jaw surgery or aesthetic dentistry. Part 1 of this article covered the historical and theoretical aspects of facial aesthetics and their importance in contemporary dentofacial treatment. Part 2 covers important aspects of the interview and clinical assessment of patients requiring alterations in their dentofacial appearance, including guidelines used in the assessment of facial proportions and symmetry. CLINICAL RELEVANCE: These articles cover the theoretical and clinical aspects of facial aesthetics required by clinicians involved in the treatment of dentofacial deformity.     

创伤性面神经损伤的临床神经电图研究

通过对69例创伤性面神经损伤的神经电图(ENoG)测定各指标的系统研究,发现面神经受损后,其ENoG完全恢复时间常早于临床恢复时间.面神经损伤后,潜伏时(LT)延迟,在正常值14%以下者可望于损伤后半年内神经功能完全恢复;25%～40%则多可于半年至一年内完全恢复;电反应在伤后15日仍中断者,一年内不能恢复,多留后遗症,LT可作为临床量化诊断分级指标.神经受损早期持续时间(DT)缩短,随着神经传导的恢复,DT延长;最大积分面积(S)及反应波幅(A)均呈降低趋势;病变严重者电反应连续性可中断,其电反应开始恢复时间越早,则其预后越好.

Facial type, dental form and cosmetics]

Is there a disgrace where there is no matching of the facial shape with the shape of the teeth? How can the dentist and the beautician solve it? This study proposes to: define the different facial shapes in Africans, specify the different forms encountered, propose a make-up according to these shapes.     

腮腺切除术中腮腺导管与面神经颊支关系的观察

目的:观察研究腮腺导管与面神经颊支之间的解剖关系,为手术中以腮腺导管为标记寻找面神经提供指 导。方法:通过138例腮腺切除手术,观察、测量腮腺导管与面神经上、下颊支的距离与走向。结果:面神经上颊 支位于腮腺导管上0.2-1cm范围内;下颊支位于导管下0.2~1.5cm内。结论:面神经上、下颊支与腮腺导管的 关系恒定,以导管为标志,寻找解剖面神经较为安全、方便、可靠。     

Facial growth: before, during, and following orthodontic treatment.

A longitudinal growth study was done on nineteen persons, involving three types of malocclusion and several types of treatment. Facial growth direction of the middle and lower face was compared during pretreatment, treatment, and posttreatment phases of the individuals. The individuals in the sample varied in direction of facial growth, Some individuals had an almost horizontal growth direction, and others had a vertical growth direction. The individuals in the sample varied in their degree of response to orthodontic treatment. Several had no change from their normal growth direction. Several had a deviation in direction associated with orthodontic treatment. The deviation was clockwise in nature and the direction changed from horizontal to vertical or from vertical to slightly backward of vertical. Middle and lower face tended to move in conjunction during all phases. If ANS moved in a horizontal direction, pogonion tended to move in a horizontal direction. If ANS moved in a vertical direction, pogonion tended to move in a vertical direction. If ANS stopped moving forward, pogonion stopped moving forward.     

点阵激光在面部美容中的疗效观察

目的：评价点阵激光在面部美容中的疗效。方法：从2009年10月-2010年8月,用点阵激光进行面部美容158例,其中皱纹52例,毛孔粗大43例,色斑35例,嫩肤28例。结果：总有效率为94％,痊愈率为58％,显效率为86％。效果最好为嫩肤,其次是毛孔粗大、皱纹、色斑。结论l点阵激光在面部美容中疗效显著。     

Facial profile-esthetics and acceptance

The human face influences and moulds one's personality and behaviour. The facial profile has become an important field of investigation by sculptors, artists, physiotherapists, orthodontists and maxillo-facial surgeons. The present study was conducted to understand the facial profile acceptance of 55 girls from silhouettee photographs judged by 3 orthodontists, 3 artists and 3 common men. To find out who appreciates the profile change the most, the chi-square test was applied to distribution of 3 professionally different groups for various occlusal categories. It was found that common bases for judging the profile do exist amongst the professionally different groups, however the public is more astute analyst of the face. Two profiles which got all acceptable votes were associated with malocclusion. Attempts were made to find out which areas on the facial outline alter the most between the acceptable and non-acceptable groups. It was concluded that the lip outline and the chin are chiefly responsible for profile acceptance while the nose alone, of its own, does not play important role. The only way by which the nose affects the facial profile is its relative position as compared to the position of the chin. Thus if the lip posture and the chin position can be corrected, a poor facial profile may be converted into a good and pleasing one.
