Positioning method for unilateral auricle reconstruction

Abstract

The invention discloses a positioning method for unilateral auricle reconstruction, the positioning method comprises the following steps: taking the axis of a human face as a calibration axis, transversely straightening by using silk threads respectively by taking the upper edge of an uninjured auricle of a patient as a starting point, and enabling the silk threads to be vertical to the calibration axis; pulling the other end of the silk thread to the reconstructed auricle side of the patient, and drawing lines at the positions, equal in length, of the silk thread on the two sides of the calibration axis to serve as a reconstructed auricle upper edge line, a reconstructed auricle earlobe lower edge line, a reconstructed tragus middle point and a reconstructed auricle earlobe lowest point; connecting the middle point of the reconstructed tragus with the lowest point of the reconstructed auricle earlobe by using the silk thread, drawing the line along the silk thread to connect the middle point of the reconstructed tragus with the lowest point of the reconstructed auricle earlobe to obtain a connecting line, and determining the range of the reconstructed auricle according to the connecting line, the lower edge line of the reconstructed auricle earlobe and the upper edge line of the reconstructed auricle, meanwhile, determining the inclination angle of the reconstructed auricle according to the principle that the long axis of the reconstructed auricle is parallel to the central axis of the nose back part. Positioning is convenient, and precision is high.

Description

technical field [0001] The invention belongs to the field of auricle plastic surgery, and in particular relates to a positioning method for unilateral auricle reconstruction. Background technique [0002] Congenital microtia is relatively common in children with congenital diseases, and the cause of the disease is still unclear. The clinical symptoms of congenital microtia are mainly auricular dysplasia, often accompanied by external auditory canal atresia, middle ear and maxillofacial deformities. At present, the main treatment for congenital microtia is ear reconstruction surgery. In China, autologous costal cartilage auricular stent ear reconstruction is the mainstream method for the treatment of congenital microtia. Creating an ear that is the same size and symmetrical as the unaffected ear is the standard for successful ear reconstruction surgery. Therefore, the accurate positioning of the reconstructed ear on the affected side before the auricle reconstruction surge...

Problems solved by technology

Disadvantages of the existing technology: the current auricle reconstruction technology used in clinical practice is relatively complicated and prone to deviation, such as the Nagata mirror symmetrical positioning method requires a special Nagata standardized film template

There is no specific reference object for Su’s positioning method for the reconstruction of the auricle, and errors are prone to occur in manual line drawing, resulting in inaccurate positioning, and the reconstruction ear is asymmetrical to the healthy side ear
