Introduction
Brief introduction of pharyngeal insufficiency Velopharyngeal insufficiency is a pronunciation and dysphagia caused by soft palate or pharyngeal wall lesions that prevent the pharyngeal pharyngeal from closing properly. The main cause of pharyngeal regurgitation is soft sputum lesions such as soft palsy, which can not move upwards and backwards to the posterior pharyngeal wall; 20% to 40% of patients with cleft palate repair have incomplete occlusion; soft palate defect and scar contracture, tumor destruction Or surgical removal of a part of soft palate, trauma, tuberculosis, ulcers, non-specific inflammation, etc., causing soft scar contracture and the disease, posterior pharyngeal wall lesions such as pharyngeal muscle spasm, proliferative surgery, pharyngeal wall tumor, inflammatory lesions make the pharyngeal wall Destruction, can not shrink forward and shrink the pharyngeal cavity leading to the disease. Physical examination revealed signs of scars, defects, etc. When the sound was "ah", the soft palate and the posterior wall of the pharynx could not be closed. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: hearing impairment
Cause
Cause of velopharyngeal insufficiency
Cause:
Soft palate lesions such as soft palsy can prevent soft palate from moving back and forth in contact with the posterior pharyngeal wall; 20% to 40% of patients with cleft palate repair have incomplete occlusion; soft palate defect and scar contracture, tumor destruction or surgical removal of a part of soft palate, trauma , tuberculosis, ulcers, non-specific inflammation, etc. cause the soft scar contracture and the disease occurs, the posterior pharyngeal wall lesions such as pharyngeal muscle spasm, proliferative surgery, pharyngeal wall tumors, inflammatory lesions cause the pharyngeal wall to break, can not shrink forward The pharyngeal cavity causes the disease.
Prevention
Velopharyngeal insufficiency prevention

Symptom
Symptoms of pharyngeal insufficiency common symptoms ear sputum soft palate scars hearing loss dysphonia dysphagia
When you pronounce, you can't close the open nasal sound, the pronunciation is unclear, the language is disordered, the food can return to the nasal cavity when swallowing, the fluid is obvious, because the eustachian tube can not open normally, there may be ear nausea, blockage, hearing loss, etc. Physical examination revealed signs of scars, defects, etc. When the sound was "ah", the soft palate and the posterior wall of the pharynx could not be closed.
Examine
Check of pharyngeal insufficiency
