1, speech development disorder: usually, speech is unclear due to poor language development. After a period of speech training, such as tongue twister and recitation, most patients' speech confusion can be significantly improved, and professional speech therapists can be invited to intervene and correct it if necessary;
2. Tongue strap is too short: it is recommended to extend the tongue strap. When the lingual frenum is too short, it will lead to the inability to roll the tongue, which may lead to Lickitung and slurred speech. The general doctor should check whether the tongue can stick out. If the tip of the tongue is w-shaped or v-shaped, it means that the lingual frenum is too short. We should improve the lingual frenulum by extending the lingual frenulum, solve the problem that the tip of the tongue can't be lifted, relieve slurred speech, and practice frequently after operation, so as to better improve the symptoms of slurred speech.
3, cleft lip and palate or velopharyngeal insufficiency: for patients with cleft lip and palate or velopharyngeal insufficiency, the pronunciation is unclear, which is caused by cleft lip and palate. Excessive nasal leakage can lead to excessive nasal sound. After professional cleft palate repair and pharyngoplasty, the normal anatomical structure of the joint can be restored, and after surgical treatment and long-term and arduous phonetic training, it can be restored;
4, the tongue has amyloidosis or vascular malformation: when the tongue has amyloidosis or vascular malformation, there will also be slurred speech. Through the operation, the tongue body returned to normal and narrowed, which solved the problems of slurred speech and inaccurate pronunciation.
5. Cerebrovascular diseases: The incidence of elderly people is high, such as cerebral thrombosis and cerebral blood circulation disorder, which leads to cerebral ischemia and hypoxia, local brain tissue necrosis, brain dysfunction, hemiplegia, blurred vision and slurred speech. This symptom often lasts for more than 24 hours. Anticoagulant drugs, such as Danshen Ligustrazine Injection, can be used to restore normal tongue movement and solve the problem of unclear pronunciation.
6. Tongue tumor: such as sublingual gland metastatic carcinoma, the clinical manifestations are nonspecific, mainly manifested as the progressive growth of sublingual masses. Some patients will be accompanied by pain, or numbness of the tongue and limited motor function, which may lead to slurred speech. If the sublingual gland mass is limited and the patient is in good health, local surgical resection is feasible to reduce the tumor load.
