Description
Technical Field
The invention belongs to the field of auricle reshaping, and particularly relates to a positioning method for unilateral auricle reconstruction.
Background
Congenital auricular malformations are common in congenital diseases of children, and the pathogenesis is not clear at present. The clinical symptoms of congenital small ear deformity are mainly auricle dysplasia, and are often accompanied by external auditory canal occlusion, middle ear and maxillofacial deformity. At present, the treatment of congenital small ear deformity is mainly performed by ear reconstruction surgery. In China, autologous costal cartilage auricle scaffold auricle reconstruction is the mainstream method for treating congenital small ear deformity. The ear with the same size as the healthy side ear and symmetrical position is the standard for successful ear reconstruction operation. Therefore, the accurate positioning of the position of the affected reconstructed ear before the auricle reconstruction operation is the key for the success of the operation. However, there is no unified standard for the position location of the reconstructed auricle in clinical practice, and it is one of the difficulties in the ear reconstruction operation to accurately locate the position of the reconstructed auricle. The prior art has the following disadvantages: the existing reconstruction technique for auricle reconstruction used in clinic is complex and is easy to deviate, for example, a Nagata mirror symmetry positioning method needs a special Nagata standardized film template. The T-positioning method requires a special T-ruler. The positioning method of the Su's reconstructed auricle position has no specific reference object, the manual drawing is easy to cause errors to cause inaccurate positioning, and the reconstructed auricle and the healthy auricle are asymmetric.

step 2: the lower edge of the lobe of the auricle at the healthy side of the patient is used as a starting point to be transversely straightened and is perpendicular to the calibration axis, and then the other end of the silk thread is pulled to the reconstructed auricle side of the patient to draw a line at the position where the silk thread is located at the two sides of the calibration axis and has the same length as the length of the reconstructed auricle lobe to be used as a reconstructed auricle lobe lower edge line;
and step 3: the silk thread is transversely straightened and is vertical to the calibration axis by taking the middle point of the tragus on the healthy side of the patient as a starting point, and then the other end of the silk thread is pulled to the reconstructed auricle side of the patient to draw points at the positions of the silk thread with equal length on the two sides of the calibration axis as reconstructed tragus middle point sites;
and 4, step 4: the silk thread is transversely pulled by taking the lowest point of the ear lobe of the healthy side auricle of the patient as a starting point and is vertical to the calibration axis, and then the other end of the silk thread is pulled to the reconstructed auricle side of the patient to draw points at the positions with the same length of the silk thread at the two sides of the calibration axis as the lowest point of the reconstructed auricle lobe;
and 5: connecting the reconstructed tragus midpoint site and the reconstructed auricle lobe lowest point site by using a silk thread, drawing a line along the silk thread to connect the reconstructed tragus midpoint site and the reconstructed auricle lobe lowest point site to obtain a connecting line, determining the range of the reconstructed auricle according to the connecting line, the reconstructed auricle lobe lower edge line and the reconstructed auricle upper edge line, and simultaneously determining the inclination angle of the reconstructed auricle according to the principle that the long axis of the reconstructed auricle is parallel to the axis in the back of the nose.
In the above technical solution, the marking method of the calibration axis in step 1 includes: measuring the distance between the head ends of the eyebrows on two sides of the patient, drawing points at the middle position between the head ends of the eyebrows on two sides of the patient as marking points, drawing the points downwards to the middle of the patient through the nose tip of the patient along the central axis of the face of the patient by using the silk threads with the marking points as starting points, and drawing lines along the silk threads to obtain a calibration axis.
In the technical scheme, the calibration axis, the reconstructed auricle upper edge line, the reconstructed auricle ear drop edge line and the connecting line are drawn as dotted lines.
In the technical scheme, in the steps 1 to 5, a marking pen is used for drawing lines or points along the straightened silk thread.
The invention has the beneficial effects that: the upper edge line of the reconstructed auricle and the lower edge line of the reconstructed auricle lobe are accurately positioned by using a method that the silk thread is vertical to the central axis of the face as a reference object, so that the upper edge of the reconstructed auricle and the lower edge of the reconstructed auricle lobe are kept consistent with the healthy auricle, errors are not easy to occur when the middle point of the healthy auricle tragus and the lowest point of the reconstructed auricle lobe are positioned by using the distance from the middle point of the healthy auricle tragus, the lowest point of the healthy auricle lobe to the central axis of the face, and deviations are not easy to occur when the inclination angle of the reconstructed auricle is determined by using the principle that the long axis of the reconstructed auricle is parallel to the central axis of the back of the nose, so that the shape and the size of the finally reconstructed auricle of a patient are consistent with the shape and the size of.
