Soft palate scar

Introduction Patients with pharyngeal insufficiency can be seen with soft sputum with scars, defects and other signs. When the sound is "ah", the soft palate and the posterior wall of the pharynx cannot be closed. Velopharyngeal insufficiency is a pronunciation and dysphagia caused by soft palate or pharyngeal wall lesions that prevent the pharyngeal pharyngeal from closing properly.

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 to contract and cause this disease. Posterior pharyngeal wall lesions such as pharyngeal muscle spasm, proliferative surgery, pharyngeal wall tumors, inflammatory lesions cause the pharyngeal wall to be destroyed, and the pharyngeal cavity cannot be contracted forward to cause the disease.

When you pronounce, you can't turn off the open nasal sounds, unclear pronunciation, and language barriers. When swallowing, the food can flow back into the nasal cavity, and the fluid is obvious. Because the eustachian tube can not be opened normally, there may be ear nausea, blockage, and hearing loss. 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.

Differential diagnosis

Soft palate motion asymmetry

Soft sputum cancer is easy to find, and there may be superficial ulcers, soft asymmetry of soft palate, etc., and the palpation lesions are harder, and biopsy is needed for diagnosis. Soft palate cancer accounts for 13.5% of the primary malignant tumor of the ankle. The etiology is similar to other malignant tumors in the oropharynx. The pathological type is more common in glandular epithelium, followed by squamous epithelium, and malignant melanoma is the third. Sarcoma is rare. The pharyngeal respiratory muscles are symmetric and flaccid: sputum, tongue, pharynx, and respiratory muscles are symmetrically flaccid, and have neurological damage such as difficulty in chewing, difficulty in swallowing, difficulty in language, and difficulty in breathing.
