    [Video Instruction for Synchronous Video Recording of Mimic Movement of Patients with Facial Palsy].

    Photografy and video are necessary to record the severity of a facial palsy or to allow offline grading with a grading system. There is no international standard for the video recording urgently needed to allow a standardized comparison of different patient cohorts.A video instruction was developed. The instruction was shown to the patient and presents several mimic movements. At the same time the patient is recorded while repeating the presented movement using commercial hardware. Facial movements were selected in such a way that it was afterwards possible to evaluate the recordings with standard grading systems (House-Brackmann, Sunnybrook, Stennert, Yanagihara) or even with (semi)automatic software. For quality control, the patients evaluated the instruction using a questionnaire.The video instruction takes 11 min and 05 and is divided in 3 parts: 1) Explanation of the procedure; 2) Foreplay and recreating of the facial movements; 3) Repeating of sentences to analyze the communication skills. So far 13 healthy subjects and 10 patients with acute or chronic facial palsy were recorded. All recordings could be assessed by the above mentioned grading systems. The instruction was rated as well explaining and easy to follow by healthy persons and patients.There is now a video instruction available for standardized recording of facial movement. This instruction is recommended for use in clinical routine and in clinical trials. This will allow a standardized comparison of patients within Germany and international patient cohorts.

    The results of neuromuscular reconstructions of the paralyzed face are difficult to assess. Very sophisticated methods are necessary to measure the motor deficits of facial paralysis or the functional recovery in the face. The aim of this development was a relatively simple system for data acquisition, which is easy to handle and which makes it relatively cheap to delegate data acquisition to centers all over the world, which will not be able to derive a data analysis on their own, but will send their data to a center with specialized equipment.

    Objective: The prognosis for facial nerve palsy (FNP) depends on its severity. Currently, many clinicians use the Yanagihara, House-Brackmann, and/or Sunnybrook grading systems to assess FNP. Although these assessments are performed by experts, inter- and intra-observer disagreements have been demonstrated. Read More
