Unilateral vocal cord paralysis(UVCP) is defined as affected side vocal cord emerges immobility or motion weakening and abnormal tension due to unilateral intrinsic laryngeal muscles suffering from disorder about motor nerve. The patients usually present with hoarse voice, disability of high pitch, cough, aspiration, or a combination of these symptoms. There are increasing therapeutics researches and case analyses regarding UVCP in recent years. Thus this review summarized the progression about its causes and treatment methods.

The authors present the clinical findings of a 30-year-old female and a 29-year-old male who both had isolated unilateral lateral rectus muscle palsy in neuro-Behcet's disease. The clinical feature related to isolated abduscens nerve palsy was identified by CT, systemic assessment and extraocular examination. These patients' constellation of findings appear to be unique: it does not follow any previously reported pattern of ocular manifestations of neuro-Behcet's disease.

Here we reported a Chinese case of bilateral peripheral facial paralysis (PFP) in human immunodeficiency virusc (HIV) infected population. A 38-year-old homosexual male patient was referred to our hospital for bilateral facial paralysis. 21 days prior to admission he had developed high fever, chills, headache, fatigue, general malaise, nausea and vomiting. Neurological examination revealed bilateral ptosis of lower lip and cheeks, as well as failure of bilateral eyes closure. Analysis of cerebrospinal fluid (CSF) revealed pleocytosis, a marked rise of micro total protein and a marked rise of intrathecal lgG synthesis. The result of HIV-1 serology was positive by ELISA and that was confirmed by western blot. His CD4 cell count was 180 cells/mm . HIV-1 viral load in CSF was almost 10 times higher than that in plasma. The patient's condition improved steadily and experienced complete resolution of bilateral PFP after 2 months.

OBJECTIVETo investigate the characteristics of laryngeal electromyography and evoked electromyography in vocal fold immobility.

METHODS108 cases of vocal fold immobility were analyzed by clinical manifestation and laryngeal electromyography characteristics, including spontaneous potential activity, motor unit potential (MUP) measurement, recruitment pattern analysis and evoked electromyography evaluation.

RESULTSNeurogenic vocal fold immobility showed a wide variety of abnormal activity. Fibrillation potentials and positive sharp waves were found in patients with laryngeal nerve injuries. For laryngeal paralysis, there was no reaction with LEMG and evoked LEMG. For laryngeal paresis, it showed decreased MUP and decreased recruitment activities with simple pattern recruitment or mixed pattern recruitment, and decreased evoked muscle response potentials were also shown with delayed latency than normal (P < 0.05) in the TA (2.2 +/- 1.0) ms(x +/- s), PCA (2.4 +/- 1.0) ms and lower amplitude in the TA (0.9 +/- 0.7) mV and PCA (1.2 +/- 1.0) mV (P < 0.05). Patients with vocal fold mechanical limitations generally yielded normal LEMG and Evoked LEMG. Patients with neoplastic infiltration of the laryngeal muscles demonstrated decreased LEMG and nearly normal Evoked LEMG with normal latency and lower amplitude.

CONCLUSIONSGeneral EMG and evoked EMG play a crucial role in the diagnosis of vocal fold immobility.

OBJECTIVETo observe therapeutic effects of different acupuncture methods for recovery of mimetic function in the patient of spontaneous facial paralysis.

METHODSOne hundred and thirty-four cases of facial paralysis were randomly divided into a mimetic muscle acupuncture group (mimetic muscle group, n = 79) and a routine acupoint group (n = 55). The mimetic muscle group were treated by encircling needling frontal belly of epicranial muscle, orbicular muscle of eye, orbicular muscle of mouth and buccinator muscle, and the routine acupoint group with acupuncture at Dicang (ST 4), Jiache (ST 6), Yangbai (GB 14), Sibai (ST 2), Cuanzhu (BL 2), etc. on the affected side. Their therapeutic effects were compared after they were treated for 2 courses.

RESULTSThe effective rate and the good rate were 94.9% and 92.4% in the mimetic muscle group and 70.9% and 52.7% in the routine acupoint group, respectively, with a significant difference between the two groups (P < 0.05).

CONCLUSIONThe therapeutic effect of needling the mimetic muscle on spontaneous facial paralysis is superior to that of the routine acupuncture therapy.

With the development of electronics and information technology, the application of functional electrical stimulation in the medical field has been expanding. However, the use of functional electrical stimulation to treat patients with peripheral facial paralysis is still in its infancy. The main problems include: (1) Finding in the signals which could fire the stimulator; (2) Exploring the parameters for the stimulator; (3) The effects on the muscle attributed to the electrical stimulation. A review on these problems is presented.

Facial paralysis is a frequently-occurring disease, which causes the loss of the voluntary muscles on one side of the face due to the damages the facial nerve and results in an inability to close the eye and leads to dropping of the angle of the mouth. There have been few objective methods to quantitatively diagnose it and assess this disease for clinically treating the patients so far. The skin temperature distribution of a healthy human body exhibits a contralateral symmetry. Facial paralysis usually causes an alteration of the temperature distribution of body with the disease. This paper presents the use of the histogram distance of bilateral local binary pattern (LBP) in the facial infrared thermography to measure the asymmetry degree of facial temperature distribution for objective assessing the severity of facial paralysis. Using this new method, we performed a controlled trial to assess the facial nerve function of the healthy subjects and the patients with Bell's palsy respectively. The results showed that the mean sensitivity and specificity of this method are 0.86 and 0.89 respectively. The correlation coefficient between the asymmetry degree of facial temperature distribution and the severity of facial paralysis is an average of 0.657. Therefore, the histogram distance of local binary pattern in the facial infrared thermography is an efficient clinical indicator with respect to the diagnosis and assessment of facial paralysis.
