“…This alternative has recently been advocated and supported by other authors [8,23 & ,24]. Using three-dimensional motion analysis, this same group showed a reduction in the significant presurgical asymmetry of facial movements [24]. None of their patients demonstrated a spontaneous smile and one patient demonstrated masseter muscle atrophy without chewing difficulty.…”

Facial reanimation surgery is a difficult challenge for any reconstructive surgeon. The use of the masseteric nerve branch to reanimate the face is gaining popularity. Its versatility, anatomical location, relative ease of dissection, low morbidity, and high potential for motor neural input make it an excellent option for many different reanimating techniques. The appropriate nerve use should be based on the type of facial paralysis, its timing, and patient factors such as age, prognosis, and desires. Understanding the benefits and potential drawbacks of utilizing this nerve represents an essential piece of knowledge for the facial reanimation surgeon.

“…Facial motion was investigated with marker displacements; this method had already been successfully used in several laboratories, without interfering with the movement. 5,6,16,19,22,30,31,35,36 The different marking method depends on the kind of motion analyzer. In both approaches analyzed in this study, the markers have to be positioned on the face and subsequently semiautomatically tracked from the computerized recordings, whereas in other studies the facial characteristics were automatically singled out without previous marking.…”

“…These methods were found to be minimally disturbing and reliable and to accurately detect total and local motion during the performance of standardized facial animations. 4,5,16,21,30,31,33 They offer a valuable support for the extraction of numeric values, which are very useful in the differential diagnosis. 4,5,21,23,29,31 The aims of the current study were to assess the accuracy of displacements of tracing landmarks in standardized facial movements for optoelectronic motion analyzer and surface laser scanning, and to compare the 2 methods in healthy people.…”

“…During the execution of the movements, special software of each camera identified the two-dimensional coordinates of passive markers positioned on facial landmarks identified by a set of 2-mm round reflective markers. 4,16,22,30,35 Subsequently, all the coordinates were converted to metric data, and a set of three-dimensional coordinates for each landmark in each frame that constituted each movement was obtained.…”

The objective of this study was to assess the accuracy of displacements of tracing landmarks in standardized facial movements. Forty healthy persons were evaluated in 2 different groups (20 men and 20 women, aged 18-30 years) with optoelectronic motion analyzer and surface laser scanning. The displacements of tracing landmarks in brow lift and smile were calculated, and the 2 methods (optoelectronic motion analyzer and surface laser scanning) were compared in healthy persons. Side-related differences were found in the tracing landmark (superciliare) during brow lift movements between both methods (the largest movements were found on the right side, P = 0.044), whereas in smile movements the tracing landmark cheilion did not show significant differences between the 2 sides. In both movements, the differences of the tracing landmark displacements between the 2 systems and sexes were on average less than 2 mm, without statistically significant differences (P > 0.05). In conclusion, normal young adult men and women had similar standardized facial movements. The 2 analyzed movements can be measured by both optical instruments with comparable results.

“…Among others, optoelectronic motion analyzers and laser scans offer valuable support for extracting accurate numerical values (Weeden et al, ; Giovanoli et al, ; Ferrario and Sforza, ; Popat et al, ; Sforza et al, ; Sidequersky et al, ; Lee et al, ). A patient's range of facial motion can be compared to reference values obtained from healthy individuals matched for age, gender, and ethnicity (Sforza et al, ; Popat et al, ); longitudinal assessments can also be performed during treatment and rehabilitation (Proff et al, ; Sforza et al, ; Hontanilla and Marre, ; Al‐Hiyali et al, ). Facial movement symmetry is another important parameter that can be measured both at rest and during mimicry.…”

Functional impairments of facial expressions alter the quality of life and their quantitative analysis is key to describing and grading facial function and dysfunction. The aim of this investigation was to quantify 3D lip movements in a group of healthy young subjects. Lip movements during five repetitions of common and random sequences of vowels and nonverbal expressions were recorded using an optoelectronic 3D motion analyzer. The mean maximum displacement of facial landmarks was used to compute 3D unilateral mobility and the symmetry indices (SI) separately for each sex. Facial mobility was significantly greater during open-mouth than closed-mouth smiles. Facial movement among the subjects was largest during articulation of the vowel /a/ and smallest for /i/. Lips were pursed with a SI very close to 95%, while smiles were slightly more asymmetric. The vowel /a/ was articulated with significantly greater symmetry than /e/, /i/ and /u/. The outcomes suggest that the proposed method characterized normal facial animations satisfactorily, so it could be a useful tool for assessing patients with facial lesions and dentofacial deformities. Patient assessment would profit from this quantitative approach, which would reduce discrepancies among several clinical examinations. Clin. Anat. 29:991-997, 2016. © 2016 Wiley Periodicals, Inc.
