With the evolution of technology, other, more sophisticated and objective methods were introduced, using cameras, computers and software of varied types [11][12][13]17,18,[20][21][22][23] , with the intent of making the method more accurate and cancel subjectivity. It happens that these methods are usually sophisticated and expensive.…”

Di fferent methods used to evaluate the movements of the face have many degrees of subjectivity and reliability. The authors discuss the ease of using these methods in clinical practice or their accuracy in scientific research. Aim:To obtain the standard for normal facial muscles movements using an objective method -the Vicon system. Materials and Methods:Light reflective markers were placed at points of interest on the face of 12 normal subjects. The movements were captured by cameras that sent the images to a computer. The points' displacements were measured between rest and maximum muscle contraction; and we calculated the means and the standard deviations (SD) were calculated.Results: When smiling, the variation of the oral commissures was between 6.45 and 12.11 mm, mean of 9.28 mm and SD od 2.83; for lifting the eyebrow, it is between 6.0 and 13.08 mm, mean of 10.57 mm and SD of 2.51; for eyelids movement there was a variation of 6.89 and 11.29 mm, with a mean value of 9.09 mm and SD of 2.20; for the movement of wrinkling the forehead, the results showed a variation of 4.16 and 10.85 mm, with a mean value of 7.56 and SD of 3.29. Conclusion:The authors obtained normal patterns for facial muscle contraction. Braz J Otorhinolaryngol. 2012;78(2):41-51. ORIGINAL ARTICLE

The ophthalmologist plays a pivotal role in the evaluation and rehabilitation of patients with facial nerve palsy. It is crucial to recognize and treat the potentially life-threatening underlying causes. The immediate ophthalmic priority is to ensure adequate corneal protection. The medium to long-term management consists of treatment of epiphora, hyperkinetic disorders secondary to aberrant regeneration and poor cosmesis. Patients should be appropriately referred for general facial re-animation. This review aims to provide a guide to the management of this complex condition.

“…Another novel approach based on the principles of moire topography to measure the subtleties of facial contours has been described and offered as a manner to objectively assess facial nerve function (19). Moire topography of the face consists of using a special camera to project an array of optical stripes on the subject's face, yielding a facial contour map; this map allows visualization of the face in three dimensions.…”

“…One study analyzed the use of moire topography in 51 patients with varying degrees of unilateral facial nerve palsy (19). In this investigation, three specific quantitative indices were measured based on counting the number of bending moire stripes in three specific areas of the face: the inner canthus, the nasolabial groove, and the oral angle.…”

OBJECTIVE To assess methods of evaluating the function of the facial nerve that have been introduced over the past 15 years, particularly in comparison with the House-Brackmann scale. DATA SOURCES A Medline search was undertaken of the English-language medical literature between 1983 and 2000 to identify proposed methods of evaluating facial nerve function. STUDY SELECTION Although all grading systems were considered, attention was focused on the systems that provided improvements in either precision or ease of use. CONCLUSIONS Because of the limitations and subjectivity of the House-Brackmann scale, several new scales of various degrees of objectivity and ease of use have been introduced. The Nottingham system offers a more objective but easy-to-use facial nerve grading system that has been demonstrated to be valid and that would be easy for the average practitioner to adopt. The authors propose a more systematic evaluation of this system to determine whether its widespread application is appropriate.
