Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Dysphagia is a feeding difficulty due to impaired function of the mandible, lips, tongue, soft palate, throat, esophageal sphincter or esophagus, which does not deliver food safely and effectively from the mouth into the stomach for adequate nutrition and moisture. Swallowing disorders can be caused by any disease in the passage from the mouth to the stomach, such as space occupying lesions like oropharyngeal cavity, esophageal tumor, etc., nervous system diseases, pharyngeal muscle weakness, etc. Brainstem injury is the most common neurological disease causing dysphagia, of which cricopharyngeal muscle achalasia is a common cause.

At present, the common rehabilitation methods for dysphagia clinically include basic training for organ tissue functions, feeding training combined with food, and neuromuscular electrical stimulation, balloon dilatation, circumpharyngeal myotomy, botulinum toxin injection, and the like. The swallowing training and the electrical stimulation treatment can improve the sensory and motor functions of the tissues of organs related to swallowing, improve the lifting of the throat, the lifting of the tongue root and the like; the balloon dilatation can reduce the resting pressure of the cricopharyngeal muscle, reduce the pressure of the pharyngeal contraction extrusion bolus entering the esophagus, increase the relaxation time and the relaxation degree of the cricopharyngeal muscle, promote the normal opening and closing of the cricopharyngeal muscle and relieve the problem of dysphagia to a certain extent by repeatedly dilating the cricopharyngeal muscle; but the clinical treatment effect is not obvious, transient and can not last for a long time. The operation of cutting the cricopharyngeal muscle is a traumatic treatment, and the cricopharyngeal muscle fiber is cut during the operation, which is easy to induce complications such as esophageal fistula, recurrent laryngeal nerve injury, pneumonia and the like. The botulinum toxin injection treatment of the site of the cricopharyngeal muscle relieves the achalasia of the cricopharyngeal muscle by reducing the tension of the cricopharyngeal muscle, has good curative effect, but has great difficulty in accurate positioning during injection.

In the clinical treatment of the cricopharyngeal muscle achalasia, the esophageal saccarography is combined with CT (computed tomography) to guide the injection of the cricopharyngeal muscle botulinum toxin to treat intractable dysphagia after brain stem damage in an existing team, and a satisfactory clinical treatment effect is achieved. Because the neck structure is complicated, the esophagus is positioned between the trachea and the cervical vertebra and is adjacent to the common carotid artery, the internal jugular vein, the vagus nerve and the thyroid tissue, the esophagus cricopharyngeal muscle is penetrated from the outside of the neck under the guidance of the CT and is continuously injected by 3 muscles, the positioning precision is required to be high, the operation process is long in time consumption, the technical level requirement on the executive doctor is high, the puncture process is easy to cause damage, and the popularization and the development of the novel medical technology are not facilitated.
