Technical Field
The invention relates to the technical field of external auditory canal expansion, in particular to an expansion device for preventing and treating external auditory canal stenosis and a using method thereof.
Background
External auditory canal stenosis is often classified into both congenital and secondary: congenital stenosis of the external auditory canal is caused by developmental deformity, often accompanied by middle and inner ear deformity; postnatal external auditory canal stenosis is mostly caused by scar tissue hyperplasia and contracture caused by inflammatory lesions, trauma, chemical injury and burns, and can also be caused by foreign body, neoplastic lesions and obstruction caused by lesions of adjacent structures of the external auditory canal.
External auditory canal angioplasty is the primary treatment for congenital and secondary external auditory canal stenosis, but restenosis of the newly created external auditory canal after surgery is a clinically troublesome and common postoperative complication. Early support after external auditory canal shaping is important in order to effectively prevent post-operative ear canal restenosis. However, no effective and dedicated external auditory canal dilator exists clinically at present, and is mainly supported by filling gelatin sponge or expanded sponge in the auditory canal after operation, which usually needs to be placed for a long time, but still cannot prevent the risk of restenosis and even occlusion of some patients after operation, and the failure reasons are that the traditional dilator has uneven pressure, is not easy to fix, and is easy to cause secondary infection.
In view of the above clinical problems, it is necessary to design and invent an external auditory canal stenosis prevention and treatment expansion device, so as to effectively improve the postoperative rehabilitation effect of the external auditory canal stenosis patients, and solve the problem of lack of a dedicated external auditory canal expansion device for medical care personnel.
