Pharyngeal muscle paralysis
Introduction
Introduction to pharyngeal muscle paralysis The pharyngeal muscles are mainly dominated by motor nerve fibers from the pharyngeal plexus, which are common in soft palate. The causes can be divided into central and peripheral sputum. Centrally seen in various causes of medullary lesions, such as medullary sputum, encephalitis, acoustic neuroma invasion and medulla. Peripheral paralysis is more common with multiple neuritis, and other causes such as infection, myasthenia gravis, dermatomyositis and skull base lesions oppress the IV, V, VI brain nerves. basic knowledge Sickness ratio: 0.5% Susceptible people: no special people Mode of infection: non-infectious Complications: glossopharyngeal nerve injury
Cause
Cause of pharyngeal muscle paralysis
Cause:
The causes can be divided into central and peripheral sputum, centrally seen in various causes of medullary lesions, such as medullary sputum, pseudobulbar medulla, posterior cerebellar artery thrombosis, encephalitis, acoustic neuroma invasion and medulla, Venous stenosis, peripheral paralysis is more common with polyneuritis, other such as infection, jugular foramen syndrome, botulism, myasthenia gravis, dermatomyositis and skull base lesions (trauma, tumor) compression IV, V, VI caused by brain nerves.
Prevention
Pharyngeal muscle paralysis prevention
Mainly due to the prevention of the cause, the reasons can be divided into central and peripheral sputum. Centrally seen in various causes of medullary lesions, such as medullary sputum, pseudobulbar medulla, posterior cerebellar arterial thrombosis, encephalitis, acoustic neuroma invasion and medulla, medullary cavity. Peripheral paralysis is more common with polyneuritis. Others such as infection, jugular foramen syndrome, botulism, myasthenia gravis, dermatomyositis and skull base lesions (trauma, tumor) oppression IV, V, VI Caused by the cranial nerves. Pay attention to the prevention of the cause from the above machine.
Complication
Pharyngeal muscle paralysis complications Complications of the glossopharyngeal nerve
When the pharyngeal muscles are paralyzed, the swallowing machine can be affected, and early fluid intake is difficult, and eating solid foods is unobstructed, and gradually develops the risk of being accidentally inhaled into the throat.
Symptom
Symptoms of pharyngeal muscle paralysis Common symptoms Nasal pharyngeal respiratory muscles are presented... Talking with nasal nasal cavity can not close the lead... Food reflux to the nasal cavity
According to the different extent of the lesion, pharyngeal muscle paralysis can be divided into complete or incomplete, unilateral or bilateral, unilateral paralysis is often asymptomatic, bilateral is heavier, due to soft palsy, the nasopharynx can not be closed, when the patient speaks There is an open nasal sound. When entering the liquid diet, it is easy to return to the nasal cavity. Eating solid food has little effect.
Check the body, open mouth "ah" sound, you can see that the healthy side moves and the affected side can not lift; if both sides are paralyzed, the soft palate is loose, can not be lifted, the pharyngeal muscle paralysis, then saliva or food can be seen in the pear-shaped fossa Stay.
Examine
Examination of pharyngeal muscle paralysis
Imaging studies can identify the cause and guide treatment. X-ray examination of X-ray chest radiograph can be used to understand whether there is any foreign body in the mediastinum or esophagus with or without space-occupying lesions; esophageal X-ray barium meal examination can observe the presence or absence of tincture to determine the lesion as obstructive or muscle peristalsis . If necessary, the use of air sputum double dysphagia chest X-ray to understand esophageal mucosal fold changes. Endoscopic and biopsy can directly observe esophageal lesions.
Diagnosis
Diagnosis and differentiation of pharyngeal muscle paralysis
diagnosis
Diagnosis can be performed based on clinical manifestations and examinations.
Differential diagnosis
It is mainly the identification between central and peripheral sputum.
