Objective facial paralysis evaluation method based on H-B grading scoring monitoring

Abstract

The invention relates to an objective facial paralysis evaluation method based on H-B grading scoring monitoring. The method is characterized by comprising steps that S1, a face image detection sample of a facial paralysis patient is acquired; S2, a facial paralysis grading classifier based on H-B grading scoring monitoring is established, and the facial paralysis grading classifier comprises multiple classifiers; S3, a facial paralysis grading evaluation class of the detection sample is predicted through the multiple classifiers of the facial paralysis grading classifier to acquire multiple prediction results based on the H-B grading scoring class results; and S4, statistics of each prediction result is carried out, the class with the largest quantity of the prediction results is taken as a facial paralysis grading evaluation result of the facial paralysis patient and is outputted. The method is advantaged in that facial paralysis grading classification based on H-B grading scoring monitoring is established, the result in consistent with H-B grading scoring can be objectively acquired, subjective deviation caused by subjective evaluation of clinic doctors carried out through an H-B grading scoring method is eliminated, and influence of experience of the clinic doctors on the facial paralysis evaluation result can be avoided.

Description

[0001] 【Technical field】 [0002] The invention relates to a method for evaluating facial paralysis, in particular to an objective evaluation method for facial paralysis under the supervision of H-B grading and scoring. [0003] 【Background technique】 [0004] Facial paralysis is a common and multiple disease, and its main symptom is that the facial expression muscles cannot perform normal functional movements. According to the difference of nerve damage position, facial paralysis is divided into peripheral facial paralysis and central. Peripheral facial paralysis is caused by nerve nuclei and damage, and manifests as total muscle and facial paralysis on the same side of the lesion. This kind of paralysis is mostly caused by wind-cold, ear or meningeal infection. Central facial paralysis originates from damage to the position above the facial nerve nucleus, and manifests as paralysis of the lower facial muscles on the opposite side of the damaged part, and is more common in ce...

Problems solved by technology

The system can better distinguish patients with facial paralysis and normal people, but it is unable to grade and evaluate patients with facial paralysis. In addition, Hontanilla and Auba proposed a 3D multi-camera acquisition system for facial information calculation. The evaluation results given by this system It is objective and sensitive, and its disadvantage is that it needs to paste markers on the patient's face, so although the evaluation results of this system are good, it is inconvenient to use and will have a certain impact on patients

[0012] In summary, although the H-B facial nerve function evaluation standard is widely used and has a strong guiding standard, its implementation depends on the experience of clinicians, and its subjectivity makes the evaluation results of facial paralysis susceptible to interference

However, the traditional objective evaluation method for facial paralysis, although its result evaluation is objective and eliminates subjective bias, its evaluation method is difficult to replace the H-B grading score, and it is difficult to adapt to the current treatment plan, so its applicability is poor, and it is difficult to be widely implemented
