چکیده

OBJECTIVE To describe a highly quantitative facial function-measuring tool that yields accurate, objective measures of facial position in significantly less time than existing methods. METHODS Facial Assessment by Computer Evaluation (FACE) software was designed for facial analysis. Outputs report the static facial landmark positions and dynamic facial movements relevant in facial reanimation. Fifty individuals underwent facial movement analysis using Photoshop-based measurements and the new software; comparisons of agreement and efficiency were made. Comparisons were made between individuals with normal facial animation and patients with paralysis to gauge sensitivity to abnormal movements. RESULTS Facial measurements were matched using FACE software and Photoshop-based measures at rest and during expressions. The automated assessments required significantly less time than Photoshop-based assessments.FACE measurements easily revealed differences between individuals with normal facial animation and patients with facial paralysis. CONCLUSIONS FACE software produces accurate measurements of facial landmarks and facial movements and is sensitive to paralysis. Given its efficiency, it serves as a useful tool in the clinical setting for zonal facial movement analysis in comprehensive facial nerve rehabilitation programs.

Facial Reanimation by Masseteric Muscle-Mandibular Periosteum Transfer

Permanent facial paralysis is a catastrophic event for involved patients. In long lasting paralysis with severe facial muscles atrophy, masseter muscle transfer is a very good choice. But its greatest problem is postoperative elongation of flap and gradual diminishing of early results and loss of symmetry. This article advocate a new modification for resolving this problem with concomitant el...

Results of End-To-Side Hypoglossal-Facial Nerve Anastomosis in Facial Paralysis after Skull Base Surgery

Introduction: The primary aim of facial reanimation surgery is to restore tone, symmetry, and movement to the paralyzed face. Hypoglossal-facial end-to-side anastomosis provides satisfactory facial reanimation in the irreversible proximal injury of the facial nerve. This study discussed the facial function results of end-to-side anastomosing of hypoglossal nerve to facial nerve when the i...

Facial Reanimation Surgery

Facial nerve disorders encompass a broad spectrum of dysfunction, ranging from subtle dynamic facial asymmetry to complete, dense paralysis. Facial nerve regeneration following injury can vary greatly and may result in hypofunction (persistent weakness or poor excursion of facial muscles), hyperfunction (hypertonicity, spasm), or aberrant regeneration (synkinesis). The impact of a facial nerve ...

Seeing is believing: objectively evaluating the impact of facial reanimation surgery on social perception.

OBJECTIVES/HYPOTHESIS Objectively measure the ability of facial reanimation surgery to normalize the appearance of facial paralysis using eye-tracking technology. STUDY DESIGN Prospective randomized controlled experiment. METHODS An eye-tracker system was used to record the eye-movement patterns, called scanpaths, of 86 naïve observers gazing at pictures of paralyzed faces (House-Brackmann ...
