Auxiliary stent beneficial to fixation and scar reduction after cranioauricular angle forming operation and preparation method thereof

Abstract

The invention discloses an auxiliary stent beneficial to fixation and scar reduction after cranioauricular angle forming operation and a preparation method thereof. The auxiliary stent is formed through 3D printing according to the auricle shape obtained after mirror image overturning is conducted on the auricle of the normal side of a patient, and the auxiliary stent is a C-shaped stent matched with the cranioauricular angle of an affected ear of the patient. The auxiliary stent comprises an upper edge fixing part, a flap attaching part and a lower edge fixing part; the upper edge fixing part is wound to the front of the helix foot of the affected ear, the flap attaching part is tightly attached to the cranioauricular angle of the affected ear, the lower edge fixing part is wound to the position below the earlobe of the affected ear, and the auxiliary stent is directly clamped to the cranioauricular angle and wraps the cranioauricular angle from the rear portion and is tightly attached to the cranioauricular angle. The auxiliary stent is beneficial to fixation and scar reduction after cranioauricular angle forming operation.

Description

technical field [0001] The invention relates to an otology medical device and a preparation method, in particular to an auxiliary bracket that is beneficial to fixation and reduces scars after cranio-auricular angle plasty and a preparation method. Background technique [0002] The main treatment for congenital microtia is auricle reconstruction. With the improvement of aesthetic concepts and the development of technology, people's expectations and requirements for auricle reconstruction are getting higher and higher, hoping to recreate a more realistic and beautiful three-dimensional auricle, and the cranial ear angle is an important factor for forming a three-dimensional sense of auricle. component. Auricle reconstruction generally includes three stages, the first stage is autologous costal cartilage carving ear stent implantation, the second stage is cranial ear angle molding, and the third stage is ear conchaplasty. In cranial and ear hornplasty, the costal cartilage t...

AI Technical Summary

Problems solved by technology

However, because the costal cartilage may be absorbed and become shallow, the angle and shape of the elevated cranial-ear angle may be deformed during the recovery process, which is quite different from the contralateral normal ear. Suboptimal, may cause significant scarring
