Abstract

The invention discloses a method for in vitro establishment of special-shaped tissue engineering scaffolds, comprising steps as follows: (1) applying computer aided design to establish a digital model for special-shaped tissues or organs; (2) guiding the digital model acquired in the step (1) into a rapid prototyping machine for processing, to shape a solid female die for the special-shaped tissues; (3) adding biodegradable materials acceptable by the medical science into the solid female die gained in the step (2), to acquire a special-shaped tissue engineering scaffold. The special shapes are chosen according to the shapes of auricle, external nose, nose prosthesis, chin prosthesis and other human issues or organs. The special-shaped tissue engineering scaffold can be effectively compounded with the chondrocytes to finally form special-shaped tissue engineering cartilages. The invention also provides a detailed method of preparing tissue engineering auricle and external nose scaffolds and application thereof.

Description

technical field

[0001] The invention relates to the fields of medicine and biomedical engineering, and more particularly to a preparation method and application of tissue-engineered cartilage applied in the field of craniomaxillofacial surgery of plastic surgery. Background technique

[0002] The defect or loss of the outer ear caused by congenital microtia, trauma, or tumor is relatively common in clinical practice; the current treatment method is mainly to excise the autologous costal cartilage, and sculpt it to reconstruct the affected ear; however, there are different shapes in different degrees. , secondary defects and other issues. The defect or loss of the external nose due to congenital external nasal deformities, trauma, and tumors is relatively common in clinical practice; the current treatment methods are mainly the use of frontal pedicled flaps and postauricular island flaps with superficial temporal postauricular vascular pedicles. , forearm leather tube, and m...
